Dear Dr. Smith
Over the past several years a number of articles have
appeared in the technical literature relative to clinical findings on individuals exposed to asbestos dust The individual studies
however raised a
have been number of
limited in scope and
questions concerning
in some instances have
the interpretation of the
resulting data
It seems evident that considerable more information is
necessary to assess properly the effects of exposures to asbestos
dust I am inviting a limited group to meet with me in Washington at 9:30 a.m. Thursday June 1 1961 HEW South Building Room 2225
to discuss the problem in some detail The objectives of this meeting are to gain a better insight on what is currently known
concerning the effects of asbestos dust on health what further
research needs to be done to obtain the information for this
assessment and the resources and facilities available for conducting
the research
I hope that you will be able to attend this meeting and participate in the discussions

Dear Paul
Recently there has been considerable discussion in various groups around this country concerning the relationship of the asbestos fibre and malignancy not only pulmonary but also abdominal Dr. Magnuson has decided to hold an informal meeting to discuss whether or not there is a problem and if there is should the U. S. Public Health Service become interested and conduct a survey This will be a limited group probably composed of Doctors Vorwald and Sander Dr. Lewis J. Cralley of the U. S. Public Health Service Cincinnati Dr. Shaw of the Asbestos
Textile Institute and one or two others
Because the U. S. Public Health Service is a federal agency Dr. Magnuson feels he cannot invite anyone outside this country He invited me and also asked for names of others to attend I mentioned your name and he indicated that I could invite you as an interested person
I do hope that you will give this serious consideration and will attend on June 1 for you have a wealth of knowledge to add to the meeting Please let me know if you can come so that I can advise Dr. Magnuson

Following your suggestion I invited Dr. Paul Cartier of Thetford Mines Quebec to attend the meeting He will be there
In our recent discussion I stated that Dr. Forde McKiver was the pathologist working with Dr. Kenneth Lynch in Charleston South Carolina I thought that he had left the university but have just learned that he still is there As a matter of fact he will be here in my office next Friday May 26. May I have your permission to see if he has any views on our malignancy problem If he has I shall let you know immediately no that you can advise Dr. Magnuson You may want to transfer the invitation from Dr. Lynch to Dr. McKiver
My tentative travel plans are to take the train to Washington arriving about 8 PM Wednesday I shall have to leave on the five o'clock train Thursday afternoon I shall be staying at the Washington Hotel

Dear Lewis
Wednesday night when we were discussing industrial hygiene instruments I questioned the type of instrument best suited for our company needs You kindly offered to contact your Noise Control Group and get their recommendations
I would appreciate it very much if you would ask them if the sound survey meter is satisfactory for our survey purposes or if we should have a wave band analy-
|
zer in addition Perhaps there is an instrument which will serve both purposes ;
I think that we had a very interesting and constructive meeting yesterday My only concern is the fact that Tom Mancuso appears to have incriminated the asbestos fibre and consequently the whole asbestos industry in his thinking whether or not the disease works in a pure exposure such as textile or in the multiple exposure occupations such as brake lining asbestos cement shingles or pipe covering Please be honest and let me know if I belabor and am too apprehensive I know that I do not understand biostatistical methods too well and if I m too apprehensive because of this please be frank and let
me know
I probably shall phone you next week before or after the Asbestos

Dear Ken
have In the first place I want to tell you that I
been greatly impressed by the general atmosphere of the meeting in Washington and I thank you for having given me the opportunity
of attending such an informative meeting
I agree with you that the conflicting opinions and
the confusion which reign among those interested in the various problems of asbestosis justify a thorough survey hoping that such a survey can produce this time solid conclusions scientifically acceptable to the majority of those concerned On the other hand
the fact that Dr. Vorwald admits himself that he did not use the
proper technique for the Saranac Experimental Study
the lungs and also the fact that the conclusions of Industrial Hygiene Foundation are not accepted even
on Cancer of the recent
by some of the
american medical authorities are of nature of rendering any one
more

less
enthousiastic about a new project

a
Following the past experience I remain slightly
apprehens in too many instances a big institution even
with a well qualified personnel has not succeeded to accomplish the
desired task either because they do not have the same interest as the
people living their problems or because they are too busy to give the time and the concentration required for any project of such
importance

I would question the method of investigation used by Dr. Mancuso in his last survey which shows that over 66 of the asbestos workers autopsied have developed a lung cancer it has to be a very selective group or workers exposed to a dangerous mixture of dust The opinion of an increased incidence of brain and peritoneum cancer in the asbestos industry would need further investigation before being accepted Also the fact that Dr. Mancuso persists to consider the results of the comparative study of the death certificates of the County of Megantic where all cases of cancer of the lungs have been detected following a special medical investigation and autopsy with the death certificates of the 2 or 3 surrounding counties without the same medical facilities and no autopsies as a conclusive proof in favor of a positive relationship this fact concurs to make me think that he has already a more or less definite opinion on some of the aspects to be investigated

Dear Myril
I have reviewed the attached draft of your letter and agree that you
have covered the subject very well I note that you have completely omitted the subject of cancer and probably have a very good reason for so doing I wonder if it might not be wise to state quite frankly that the question exists concerning the association of asbestos and cancer and that the U. S. Public Health Service would be able to give factual evidence for or against such a relationship This survey of course would cover all other aspects of health in the asbestos worker in addition to possible cancer
Aside from this thought I have
that you will receive a favorable vote in
ask Dr. Magnuson to draw up the framework
no other suggestions I do hope
the very near future so that we can for the survey

C. W. Hite
Division Managers Meeting June 21 1961
You may wish to discuss the following information at your forthcoming meeting
For many years British and South African medical authorities have associated lung
cancer with the inhalation of asbestos fibers In recent years American writers
have reported numerous cases of cancer not only of the lung but in other parts of the body associating these conditions with asbestosis While we have not had many cases of cancer in our Company these are numerous enough in other companies
to osuse Me some concern
Two weeks ago a meeting was called in Washington by Dr. Harold Magnuson Chief of the Occupational Health Division U. S. Public Health Service I was invited along with Dr. Paul Cartier Thetford Mines Dr. Arthur Vorwald former head of the Saranac Laboratory and now at Wayne University Dr. A. Sander a specialist in industrial pulmonary diseases in Milwaukee and Dr. Myril Shaw Secretary of
the Asbestos Textile Institute Also present were several men from the U.
Public Health Service who carried out the Diatomaceous Earth Survey a few years
ago It is Dr. Magnuson's responsibility to protect the health of the American worker and he called the meeting because he had become concerned over the asbestos
and cancer question
The immediate cause for calling the meeting was a report by Dr. Tom Mancuso who under the auspices of the University of Pittsburgh had studied the health of workers
in a brake lining plant in Pennsylvania Dr. Mancuso reported that there were 19
cases of lung cancer mong 31 people who had asbestosis This is a phenomenally
high incidence In addition the incidence of abdominal cancer was 50 times higher
in this group than would be anticipated in the normal population Because it is a recognisfeacdt that inhalation of certain fumes in the dye industrcayn cause cancer in parts of the body other than the lung it was felt that the same night .
be trus for inhaled asbestos
At the end of cum all day meeting there was an unanimous decision that a problem
exists in the
me } industry The question of whether or not an association
exists betarea
a
end cancer should be answered preferably by an authorita-
tive group suck
V. 8. Public Health Service rather than by University
workers Althous
muson has the authority to investigate any American
fi.
industry in whhi e fc eelsha health problem exists he would prefer to be invited
by the industry to undertake a survey
'
Dr. Magnuson indicated that he would set aside two million dollars in his budget
poems
if he is invited to study our problem There will be no direct expense to industry
other than making men and records available to the survey team The whole program
would be correlated with studies carried on in other parts of the world where
different types of asbestos fiber are used It is expected that a preliminary
report could be ready in approximately 5 years
2
Last week Dr. Shaw and I reported the results of the Association meeting to the Asbestos Textile Institute Their Board of Governors voted to invite Dr. Magnuson to survey that part of the asbestos industry Letters have been sent to member companies requesting approval of this action
I believe that we should participate in such a survey realizing that if asbestos is incriminated as a cause of cancer it might affect our Company business quite seriously However I feel that it is better to have the question answered by factual evidence rather than by hearsay Certainly we could be no worse off than
we are today when many doctors and lawyers quote medical texts associating cancer and asbestos On the other hand if the S. Public Health Service finds that no relationship exists it would be of tremendous value in our future Workmen's Compensation cases and product liability suits

9. Health Education & Welfare Dept. Proposed Survey of the Asbestos Industry
ek week.
Referring to your request of June 26 regarding the above we are returning
herewith our voted ballet on the two questions that you present
Unfortunately I was not present when this matter was presented in detail at the last A.T.I. meeting but I have spoken with Mr. B. A. Schuman and had a reflection of Raybestes Manhattan's opinion from Mr. J. A. Bettes
As you will note it is our opinion that we want to be very cooperative in
having the Asbestos Textile Institute offer every facility they have at
their command to assist the Public Health Service in the event that they
concernedthere wish to make a specific study of this industry however we do not feel
that it is wise to portray to them that are unduly
the
health conditioo f nthse industry and what has been done in
of
study and cerrection methods perhaps creating the opinion that
have
been some deficiencies On the other hafen el thd at a
of
" Study and thought on the part of all manufacturers have improved con ditions over the years but that if it is deemed adviseable that a study
be made then we as representative of the Asbestos Textile Industry should do all in our power to assist It is for this reason that we have studi
negative on Question # with the thought that probably our approsoh and opinions to Dr. Magnuson Chief of the Public Health Service could be phrased more in line with the thoughts I have expressed herewith
~~
We have voted affirmatively on question # feeling that if the Public Health Service is to investigate the Asbestos Industry then a subcommittee composed of medical son fully conversant with the problem will offer the greatest assistance in these matters

You say these are a few of the obvious questions and I wholeheartedly disagree they are in the slightest degree obvious on the basis of any evidence I have ever seen However my
impression of such statements I have seen put out by officers of the Public Health Service is that these are likely to be the only questions asked that asbestos and the asbestos industry are already condemmed
Needless Needless It appears to me that whereas a person many years ago -
used most often to die of complications medical ignorance
has now been refined to the point where any person at any time
employed in the asbestos industry who suffers a spot on his lung
or death from cause not too obvious is automatically classed a victim of asbestosis I return to my opening remarks about inability to define what that is etc.
I submit as a splendid example of the above a diagnosis
of asbestosis given us on a former employee whose total connection with the asbestos industry had been a few years as Office Systems Manager There is extreme doubt in our minds
that he was ever closer to asbestos than viewing the material
in a showcase
Accordingly until there is some clarification as to the
approach this proposed investigation might take I shall heartily recommend that this Company vote no to both propositions

To discuss pulmonary asbestosis study in Passaic County
Review of previous field reports
We met for lunch in the library of the Paterson Clinic Dr. Celikoff began the discussion by stating that in a hospital as small as Barnert 125 beds they have had 6 deaths due to
pulmonary asbestosis diagnosia by autopsy in the last 10
years Dr. Selikoff has had 21 patients with severe asbestosis of these 2 have died due to cancer of the lungs both cases were diagnosed as asbestosis in 1954 in one lung cancer de-
veloped in 158 in the other lung cancer leveloped in 159
Dr. Jelikoff mentioned that Fortune Magazine put out a list
of the 500 largest companies 1000-5000 employees in the United
States 7 of the asbestos companies were located in New Jersey Dr. Selikoff said there are two things that must be considered -
the individual exposure to asbestos and the clinical hazard
peculiar to asbestos inhalation which is carcinoma Dr.
Selikoff said that in Great Britain there were 49 deaths due
to cancer of the lung in 250 asbestosis patients Dr. Tom Mancuso did a study for PHS on diability applicants with asbestosis his findings confirmed the Great Britain finding of intraperitoneal cancer in addition to lung cancer
Dr. Selikoff said that he had met with Dr. Harold Magnuson Chief Occupational Health Program PHS about the problem Dr. Magnuson is eager to do some studies in this field He
has little literature available on the subject Dr. Magnuson recently met with representatives of the asbestos industries reviewed the literature with them and asked their support and cooperation in undertaking studies in asbestos exposure This group recommended that the asbestos manufacturers display leadership and support these projects As a result asbestos industries throughout the country are now being polled for their reactions Dr. Magnuson assured Dr. Selikoff that if the industries did not support these studies PHS would Dr. Magnuson or his staff members would be willing to come to New Jersey and help with the planning of the study One of his staff Dr. Smith is now in Europe reviewing the studies

U.S.P.H.S. Survey
In previous correspondence on this subject I indicated that Mr. R. R. Porter
President of Keasbey and Mattison requested the Asbestos Textile Institute to call another meeting of representative companies to discuss with Dr. Magnuson the proposed survey Invitations were sent to several concerns and Mr. Porter was asked to invite certain representatives from his Asbestos Cement Products Group
When the letter of invitation was sent by Dr. Shaw of the Asbestos Textile Institute Mr. Porter telephoned Dr. Shaw vehemently upbraided him for his action and said he would refuse to attend the meeting because the invitation had not been sent by a president of one of the member companies He stated that he refused to talk to anyone not on a presidential level
The meeting was held on September 25 and was attended by representatives from
Raybestos Manhattan the H. K. Porter Company and Manville The doctor
from Keasbey and Mattison was attending another meeting in the same hotel but had been forbidden to attend our meeting Dr. Magnuson outlined the purpose and
the method of the proposed survey
in the survey
Those present felt that we should participate
.
Subsequently I learned that Mr. Porter has refused to participate and apparently has managed to change the thinking of some people in Raybestos Manhattan Mr. Zimmerman of Raybestos indicated to Dr. Shaw that he should not send a letter of invitation to Dr. Magnuson Therefore the Asbestos Textile Institute has
advised Dr. Magnuson that they do not wish to participate in an industry survey but will cooperate if Dr. Magnuson initiates the study himself
I believe that this can have serious consequences because surveys of the asbestos
industries in Massachusetts and New Jersey definitely are being planned and
others in Ohio and Pennsylvania are proposed I would surmise that without the
company willingness and cooperation of the Asbestos Textile Group Dr. Magnuson may be forced to devote his funds to various state groups requesting aid I shall learn more about this next week at the Annual Meeting of the Industrial Hygiene Foundation at Pittsburgh

You will recall that we met with several others in Dr. Magnuson
office in June 1961 to discuss this subject Plans now are well developed
for this survey and three of the doctors would like to see some of the
Canadian mining operations They propose to visit our mine on September 25
and 26 and wonder if it would be convenient to see Thatford on September 27
and possibly the 28th The purpose of this trip would be for basic knowledge
only and is not part of the survey of the U. S. workers

OBJECTIVES AND GENERAL PLAN FOR OCCUPATIONAL HEALTH STUDY
OF THE ASBESTOS PRODUCTS INDUSTRY August 21 1962
Division of Occupational Health
Public Health Service
DEPARTMENT OF HEALTH EDUCATION AND WELFARE
OCCUPATIONAL HEALTH STUDY OF THE ASBESTOS INDUSTRY
Asbestos is a generic term applied to a number of fibrous crystalline silicate minerals Although chemically they are grouped as hydrated silicates they vary greatly in degree of hydration complex composition
of the silicate and physical properties of the crystalline fibrous
structure
Reference was made to asbestoass early as several centuries B.C. It
was not established as a mineral of industrial importance however until around the end of the last century Because of outstanding properties of chemical resistance fibrous structure and incombustibility asbestos
has a wide variety of uses in modern industrial technology It is used
in the manufacture of textiles felts ropes brake linings roofing and
flooring flooring materials asbestos products gaskets insulation mater-
ials special papers filters and plastic products These find use in
practically every major industry
Information from the Bureau of Mines Minerals Yearbook Volume I
1958 shows an apparent consumption of around 685,000 short tons of
asbestos in this country in 1958 in the manufacture of asbestos products
Chrysotile accounted for around 642,000 tons crocidolite 26,000 tons
and amosite 17,000 tons The consumptioonf other types of asbestos in
this Country appears negligible
Of the above tonnage this Coun-
try produced around 41,000 tons of chrysotile the remainder of the
chrysotile coming predominantly from Canada
The crocidolite was
.
imported mainly from Bolivia Australia and the Union of South Africa
-3-
malignancy associated with asbestosis The published data in this regard
are based largely on mortality statistics and autopsy records of former
employees in asbestos industries While some of the reports strongly suggest that lung cancer is an occupational hazard of asbestos workers the literature in this respect is by no means unanimous and the data are often conflicting
Several factors may account for this apparent discrepancy in the technical literature Diagnostic criteria for asbestosis are often poorly defined making valid comparisons of studies difficult if not impossible Conclusions are too frequently applied to classification encompassing all asbestos workers and are not confined to the group under
investigation Information on such factors as sex community air pollu-
tion personal smoking habits and family history of cancer are absent in the majority of reports Environmental data are scanty No clear attempt
is made to define exposures to different asbestiform minerals or associ
ated materials Mortality studies often encompass a broad exposure group and do not relate to a specific and single exposure Despite the accumulated knowledge the following questions remain unanswered
1. What is the prevalence of pneumoconiosis in asbestos workers
actively employed in the asbestos products industry industry
2. What is the significance of exposure to different sources and
forms of asbestos and to other materials commonly employed in
this industry in the development of pneumoconiosis
3. What is the role of occupational respiratory disease in the development of the pneumoconiosis
4. Are malignancies occupational risks of the asbestos worker in the products industry If so what are the important etio-
logical factors
B. Laboratory Studies Laboratory research is necessary to develop sampling and appraisal
techniques which will permit a detailed definition of asbestos dust
exposures In addition animal studies are needed to evaluate any re-
lationship between asbestos fiber exposure and tumor formation
plant Environmental Studies
The environmental studies will be designed to define the working en-
vironment of the various plants Particular emphasis will be placed on levels and nature of exposures asbestos dust Exposures to other
air contaminants - silica mineral dusts fumes mists vapors and
gases - which may be associated with asbestos or its processing also will be carefully assessed plant Medical Studies The medical studies will be designed to develop specific information
relative to the effects of asbestos dust and other associated expo- expo-
sures on health They will include medical examinations of a substan-
tial portion of the asbestos the asbestos industry
~
and provide a sufficient background for periodic follow medical surveys The medical findings will be related to the various aspects of the environmental exposures

U.S.P.H.S. Survey Asbestos Industry
On June 19th I wrote to you outlining this proposed survey report since that time
Following is a progress
I have learned from confidential sources that some states are contemplating health surveys of asbestos workers using their own facilities and ignoring the U.S.P.H.S.
plans New Jersey probably will start with a survey in Passaic County Obviously .
each state will follow its own ideas in survey methods With no consistency between them there will be as many different reports and opinions as there are states This
could be very detrimental to our interests and therefore we are trying to get interested companies to cooperate with Dr. Magnuson in Washington
The Board of Governors of the Asbestos Textile Institute agreed to invite the U.S.P.H.S. to make a survey However when the Asbestos Textile Institute membership was polled Mr. R. R. Porter President of Keasbey & Mattison vehemently opposed this survey both
vocally and in writing A copy of his letter is attached Reading this carefully you will see that the man is opinionated has not sought information on the subject and
has made mumerous irresponsible statements not founded on fact
On September 8th at the annual meeting of the A.T.I. Mr. Porter repeated many uncalled for remarks interspersed with personal prejudices Fortunately one else at the meeting appeared to agree with him
In an effort to educate Mr. Porter and to show him the seriousness of the situation I have arranged a meeting with Dr. Magnuson in Philadelphia on September 25th In addition to Mr. Porter invitations are going to executives of the following companiest
Raybestos Manhattan
H. K. Porter
U. S. Rubber
McCluskey American Asbestos Company
Union Asbestos
Gatke Corporation
Carolina Asbestos
National Gypsum Phillip Carey Flintkoto
Company
I hope that after this meeting everyone will see the necessity for a comprehensive survey carried out by a responsible agency

Unfortunately I have just learned on January 11 that our Dr. Kenneth Smith will be unable to be present at the coming A.T.I. Meeting at which
time many of the company doctors will in attendance
I am afraid we let the announcement go too long and he has made a previous commitment to be at our sines and the date can't be changed so
we have lost th onatht at score
Dr. Smith explained to me that be and possibly others will be contacting
various Asbestos Textile Industry plants in Engl andaon n td he Continent very soon Dr.Bette of Turner and Newell in England is a key man in the
situation and be will undoubtedly meet with the American doctors
Dr. Cralley through Dr. Smith would very much like to arrafn orgDe r.
Paul Gross Pathologist at Mellen Institute in Pittsburgh to accompany
the greep I am advised that a non government employee is not considered
proper unless sponsored it is Dr. Cralley and Dr. Smith's request
that the A.T.I. appoint and sponsor Dr. Gross as their representative
This would be on the basis of no cost to the A.T.I. but it would make
Dr. Gross who is an authority on Asbestosis available to the Asbestos
Research Council of England
Will you be good enough that it is placed on
to discuss this matter with Mr. Peele and see agenda for Band of Governor's consideration

GREAT BRITAIN
April 1 - The Ministry of Pensions and National Insurance of Her Majesty's
Government We met with Dr. J. Watkins Pitchford Dr. J. C. McVittie
and Dr. Sims
The ministry of Pensions and National Insurance is primarily interested in pneumoconiosis from the point of view of compensation There are some 12 or 15 pneumoconiosis medical boards in the British Isles with three primarily interested in asbestosis The latter boards are located in London Manchester and Sheffield Last year there were some 3,600 new cases of pneumoconiosis of
all kinds which came to the attention of the boards throughout the country
Of these around 2,770 were from coal workers 100 from foundry workers 70 from pottery workers and 40 from asbestos workers The potential number of workers at risk in the asbestos industry approximates 7,000 which would indicate
approximately five compensation cases per year per thousand workers at risk
This is very close to the figure given for the number of pneumoconiosis cases given in coal workers during the same time period It was also stated that in recent years lung cancer has been found in about 40 percent of the autopsied
cases of asbestosis During the period 1955-5391 cases of asbestosis were
given compensation among asbestos insulators In Belfast 11 mesotheliomas
have been diagnosed of which nine had an industrial asbestos exposure
As far as the diagnosis of asbestosis is concerned the medical boards go primarily on 1 exposure to asbestos dust 2 clinical judgment which includes the presence of one or more of the following signs and symptoms
rales clubbing diffusion defects with a decreased maximum breathing capacity It was felt that the pulmonary function tests can differentiate a diffusion
defect from some other condition which might be confused with asbestosis
April 1
Ministry of Labour and National Service of Her Majesty's Government
We met with Dr. W. D. Buchanan
The factory inspector's responsibility is primarily to enforce the factory inspection law which has to do with the maintenance of good working conditions in factories of Great Britain The medical section is primarily advisory to
the factory inspectors
One of the early stimuli to the current studies of asbestosis and lung cancer
came from a 1947 report of the Chief Inspector of Factories which showed that
during the period 1924-46 out of 235 cases of asbestosis which had been autopsied 31 or 13.2 had carcinoma of the lungs 17.2 of males and 8.4
of females In the annual report of the Chief Inspector of Factories for
the
year 1955 covering the period 1924-54 of 344 asbestotics autopsied 55 or 16.0 showed evidence of lung cancer 20 among males and 10.1 among females
There is some current interest in the Ministry of Labour on the effects of
nitroglycerin on the health of workers Professor Wayne Department of the - Practice of Medicine at Glasgow University has been working on this problem
~ 3-
April 2 - The Department of Applied Physiology London School of Hygiene and
"
Tropical Medicine We met with Dr. M. L. Thompson and staff and
Dr. W. J. Smither
Dr. N. L. Thompson has done a great deal of work in pulmonary physiology relating to asbestosio Dr. Thompson outlined some of the problems which are exparently operating in cases of asbestosis which involve primarily a decrease in the inspiratory capacity with a resultant decrease in the vital capecity total lung volume a decreased compliance and diffusion defects Ia esbestosis one finds that the diffusion defect is probably most easily Ieasured Dr. Thompson uses a single carbon monoxide test which involves inhaling the carbon monoxide mixed with 14 helium to test the residual volume and then measuring the amount of carbon monoxide in the expired air
after the breath was held ten seconds to allow the diffusion to take place The carbon monoxide diffusion test in Dr. Thompson's laboratory involved the
use of ca infrared CO analyzer developed by the Infrared Development Company Limited Welwyn Garden City England The laboratory also used a WatersConley Photoelectric Ear Oximeter in their studies
In asbestosis the diffusion or resistance of the alveolar membrane to the
passage of gases is decreased presumably due to the development of fibrosis the alveolar walls It was pointed out that one must take into account the
in
age
of the individual for the diffusion gradient falls consistently with age
Mr. Hills a statistician in the School of Hygiene stated that when eight doctors experienced in clinical diagnosis and in evaluating disability were interviewed regarding the symptoms most valuable in diagnosis the order ran . dyspnea ray findings rales cyanosis clubbing of fingers exposure to dust cough and sputum and survival The statisticians found a very good multiple linear correlation between cyanosis dyspnea rales and ray findings and percent of disability The level of disability as measured by the pneumoconiosis boards was not correlated with the lung function tests
but there is a trend toward correlation with the inspiratory capacitusinyg using
Dr. Thompson demonstrated the use of the whole body plethysmograph using
esophageal balloon to measure pressure compliance

Dr. Enterline met briefly with Dr. Reid Tuesday afternoon to discuss problems relating to the Medical Research Council's questionnaire on chronic bronchitis Dr. Enterline pointed out that when chronic bronchitis is defined as a productive cough the questionnaire did not detect known population differentials in chronic bronchitis Dr. Reid feels that the most important part of the questionnaire deals with repeated attacks of respiratory disease and presented data showing that this has differentiated rather clearly populations in which the prevalence of chronic bronchitis was known to differ He feels that a productive cough represents a chronic bronchitis in its very early stage and that this is aggravated by such things as air pollution to produce repeated attacks He feels that it is at the point that repeated attacks can be
detected that observations become of epidemiologic significance

April 3 - Meeting of Asbestosis Research Council Reading University
The Asbestosis Research Council sponsored a symposium of speakers from industry Universities of Reading and Cambridge and Pneumoconiosis Research Unit Penarth Clamorgan to discuss problems and current research on the effects
of exposure to asbestos dust and fibers
A series of papers were presented starting with a background paper by Dr. Gaze describing the properties of the three major types of asbestos used chrysotile crocidolite emosite and the source and commercial use of these minerals Re
stated that annually the United States uses about 500,000 tons of chrysotile compared with roughly 100,000 tons in the United Kingdom 10,000 tons of crccidolite compared with 4,500 tons in the United Kingdom 15,000 tons of exosite compared with about the same amount in the United Kingdom The figures he quoted for the United States are somewhat lower than those shown from the Dureau of Mines Minerals Yearbook Volume I 1958
Dr. Pack Turner Brothers Asbestos Company Ltd. spoke of asbestosis from the point of view of the factory medical officer He noted that there seemed to be a correlation between the number of years worked in the factory and the
pirocatega of men having asbestosis The shortest exposure reported by Dr. Pack was six months with the disease being recognized 24 years later at
cutopsy The microscopic lesions of asbestosis as outlined by Dr. Knox were 1 desquamation of the bronchial membrane 2 endarteritis 3 thickening of the interlobar tissue 4 thickening of the subpleural tissue 5 an
increase in the fibroblasts 6 obliteration of some alveoli 7 occasional giant cells 8 amorphous brown pigment and 9 presence of asbestos bodies
. Dr. Knex has seen no mesotheliomas in this population He discussed1939-61 provisional figures of a plant population observed for 28 years 1939-61 as
- a follow of an earlier study by Dr. Richard Doll indicating that the _- obscrved deaths due to all cancers and due to lung cancer were no more than
might be expected in the general population

It was noted that in compliance with the Factory Inspectors Act of 1933 environmental exposures to asbestos dusts and fibers during the subsequent period were dramatically lower than that of the previous study He felt that the above data reflect the improved dust conditions in the factory The above study is expected to be completed and published in about another four years For this reason the above data are provisional and are not available at this
time for publication

Professor Holt of the University of Reading discussed research he was doing
sponsored by the Asbestosis Research Council One of his findings is that the amount of ferratin which is absorbed onto the asbestos body is several times
that of the albumin seen This must mean that the protein is being put out by a
cell and is not coming from the plasma itself It was estimated that it takes at least two months to develop an asbestos body for they first find asbestos particles in macrophages then in giant cells then in fibroclasts Work done by Dr. Davis University of Cambridge indicates that a macrophage is some sort of stem cell in the giant cell - fibroblast series Dr. Davis also pointed out that the early lesion in asbestosis is found in cells just under the basement
membrane in the alveoli Next there is nodular lesion formation with interstitia
fibrosis in the septum which could be termed a type of interstitial pneumonia There are subsequently increasing amounts of lung consolidation Dr. Davis state
that in the development of the giant cells a series of microvilli varying in
length but about 12 0 units in diameter apparently interdigitate to produce thes
cells Asbestos particles are found in macrophages which have migrated to the trachea and lymph glands but apparently there is no development of eshectos eshectos
:
bodies in these extraneous sites
Dr. Smither Cape Asbestos Company outlined the problems of pulzonary function as seen by a factory medical officer He pointed out that the basic pathology involved a stiffening of the lung due to interstitial fibrosis and pleural thickening These processes decrease compliance and also contribute to an alveolar capillary block with a diffusion defect Dr. Smither stated that there
is marked disagreement in ray interpretation and that the ray cannot be used-
to demonstrate progression
Mr. Ross Hunt Pulmonary Function Technician British Belting and Asbestos outlined their program of lung function testing They determine residual capacity obtain an FEV and MBC do diffusion testing helium and an excercise test These pulmonary function tests are done as a part of
employment and periodic examinations
Company
Dr. Beverley Medical Officer at British Belting and Asbestos Company outlined the employment examination he uses with emphasis on medical history to rule out chest and heart conditions and collagen diseases including Caplan's Syndrome He examines the prospective employee by ray as well as by clinical examination and as mentioned before pulmonary function tests are used to
provide a baseline
Dr. John Cotes of the Pneumoconiosis Research Unit at Penarth outlined some of
the problems of standardization of methods relating to pulmonary function testing He stated that they have circulated for comparative purposes a series
of aliquots of various gas mixtures to laboratories throughout Great Britain who are doing diffusion tests There are three major sources of error in these
tests 1 analytical methods 2 apparatus used 3 differences in terminology The primary source of error was in the analysis of carbon dioxide

of asbestosis Dr. Smither felt that there was some small degree of asbestosis in all patients and that infection of any kind including the chronic bronchitis so prevalent in England might be the trigger mechanism for the development of _' asbestosis Dr. Smither reported a series of asbestos workers who were

East Germany has reported more in their asbestos workers than in general population We were also told that no pleural plaques were seen in West

and tuberculosis in that asbestosis may predispose and accelerate the
development of tuberculosis However the incidence of tuberculosis East Germany was said to be higher than that of West Germany so that
major conclusions can be drawn Dr. Buckup pointed out that many of former workers from East Germany were now living in West Germany and

Dr. Bjure's primary interests are in byssinosis where he has done work with
Dr. Ecuhuys who is presently working at Emory University in Atlanta Georgia In addition to this work in byssinosis Dr. Bjure has been working in the area of pulmonary function with particular interest in the diffusion capacity of the lungs He has also done heart catheterization on all their work groups His
major finding is that the diffusion capacity is significantly lowered in
asbestosis as compared with workers in glass wool industries He stated that
in asbestos there is said to be an alveolar membrane block but he feels that
there is also a block in the small arterioles with thickening of the vessel walls They are hoping to do a follow on the men in their study which is to be reported in the magazine Thorax some time in the near future
We also talked with Dr. Sven Lindell also a clinical physiologist at the
Sahlgrenska Hospital He too was interested in byssinosis and indicated that
the incidence in Sweden is increasing In a recent new study brought on by local union pressure using Schilling's questionnaire they found that the incidence was as great in the newest factory as in the oldest There was a decrease in incidence in a factory where rayon was primarily used and very little cotton was handled He also noted that spirometry on a Monday after a two holiday revealed a significant decrease in the pulmonary function Dr. Lindall stated that there is apparently a relationship between smoking and byssinosis If the workers smoke their pulmonary complaints were
intensified This causes cotton mill workers to smoke appreciably less than _ the general working population Dr. Lindell is going very soon to the University
of Malmo where he will be Chief of the Clinical Physiology Laboratory at the
new medical school there

DENMARK
April 27 - Dr. A. Grut Senior Medical Inspector of Factories Copenhagen
Denmark
Dr. Grut was greatly interested in the occupational health study we have underway of the asbestos products industry in this Country We spent considerable time discussing the scope of our study Dr. Grut has primary interests in
factors of the work environment in the factories in Denmark as well as related
compensation problems The actual number of asbestos workers in Denmark is not known but there are some 300 in the union designated as insulation workers and 30-40 as lagging workers Some asbestos is used in both weaving and
building materials but the number of workers involved is unknown In a study of 35 insulation workers who had been working from 18-45 years with an average
experience of 29 showed only lung symptoms There
when emosite was
years 22 of the 35 had some ray changes nine of the cases changes 19 had pleural changes but only three of the 23 had were also some plaque formation in these insulation workers
used Although there have been some compensation cases from
exposure to asbestos no lung cancer has been identified but it was recognized
there are only small numbers involved If a person is diagnosed as having pneumoconiosis he is advised not to work with asbestos However if he continues to work with any pneumoconiosis dust he is required to
wear a respirator
The industries in Dermark have an annual ray program with nearly 100
participation as they get paid by the factory to have their chest rays taken In the asbestos factories 30 x 40 cm films are taken as well as 10 x 10 cm
The men who read the films find that the small size is more satisfactory for
asbestos exposures and Dr. Grut is now tempted to use only the small films for
the cebestos workers He is also considering instituting a program of taking
. films for silicosis using the small size

Are ANALYTIC METHODS A project to develop separation and concentration pro-
cedures for spectrochemical analysis of metallic elements is continuing with me
evaluation of methods by radiotracer techniques Work was resumed on the de-
velopment of volatization characteristics of beryllium and of internal standard 6
elements which have been found to be most precise for the quantitative spectro-
aten
graphic analysis of beryllium in biological materials The analytical losses
of beryllium during the application of the direct spectrographic method are
being evaluated
.
Recent work has included refinement of the spectrographic method for
beryllium indium and antimony development of a quantitative spectrographic method for indium and antimony in human sweat samples and development of a method for the collection of urine samples in field studies and for their transport to the laboratory for gas analysis
DUST SAMPLING TECHNIQUES
Electron micrographs indicate that the dust
cloud produced bya newly constructed device for dispersing dry asbestos dust
jm, differs
character from that produced by the device for dispersing wet a
asbesto
underway to determine the effects of density and viscosity of the
bed collect
Blution and the effect of dust particle densities upon settling
time a
by Stokes law The mathematical model indicates that wide
te
oe
differences in theoretical settling times in a Dunn cell are possible for the
same diameter particles in commonly used collecting media
COAL MINE STUDY
Medical examinations by mobile field units of both in-

Dear Lewis
Many thanks for letting me read the attached Trip Report I
sure wish that I could have been with you
I have heard no repercussions whatsoever following the Asbestos Textile Institute Meeting You must have done an excellent job in allaying their fears If I do hear anything in the future I'll let you know

Dear Mr. Hite
I am writing in follow of the occupational health study which our Division is undertaking in the asbestos products industry
Plans for initiating elements of the study as outlined in the protocol which Dr. Kenneth W. Smith has received are progressing A study of cohort groups
employed in the asbestos products industry using social security records is
now underway It will be another year however before data from this source can be assembled and analyzed
We are ready now to begin the plant study as outlined in the protocol to obtain baseline data for prospective follow Although the environmental and medical phases of the plant study will be conducted independently it is important that we obtain the information available through both these avenues if meaningful correlation of the data is to be made and the objectives of the study are to be achieved We plan to start the environmental work early this fall It would be approximately another year however before the medical phase of the plant study gets underway
We believe that information obtained from an environmental and medical study of some of your selected plants as outlined in the protocol would be invaluable in obtaining factual data to achieve our objectives For this reason it is requested that you participate in the environmental and medical plant study We can get together at a subsequent date in discussing specific asbestos products plants which would be suitable for inclusion in the study Other plants in the asbestos products industry also will be requested to participate so that representative and statistically
Mr. C. W. Hite --- 6/25/63
meaningful study groups can be constructed We cannot at this time give a specific time for scheduling the start of environmental studies in individual plants which may be selected We will however give a minimal notice of two months and longer if possible so that satisfactory arrangements can be made prior to
our arrival
We would greatly appreciate early consideration of this request for your participation in the study
Sincerely yours

ImplementPliannogf Cecupational leaitu study of AsbestosProducts Products industry
A pretecel was developed and approved by the Division of Occupational Health Public Health Service August 21 18 covering general plans for a study of
occupational health problems in the asbestos produeia manufacturing industry as well as specific plans February 6 1935 for obtaining necessary caviron
mental mental and medical plant data
Past plant mestical and environmental studies of the Division have been cross-
sectional in that health problems of an lacustry were studied by correlating per-
timent medical and environmental sata collected through a time approach In
those studies all of the medical and environmental dala were collected by official
agencies Twy were essentially a one period to tune study with retrospective
ata baving minimal meaning due to its sparsity and the inability to confirm ita
vaikity With With the rauer massive cavironmental exposures of the past associ
atulatul with the occurrence of frank occupational tseases often la epidemia pro-
portion this type of study has been very useful in developing information relative
to the nature of such diseases and their prevention
-
However with the increased attention given to the control of plant just ez-
posures and to medical programs providing surveillance over employees the effects of exposures have changed from an acute to a chronic type response often requiring periods of a lifetime of employment before the response may be manifest through today's study techniques
This response to low levels of exposure over prolonged periods as well as broa.lenad knowledge on the suspect relationship of such exposure to diseases which in the past were considered as entirely nonoccupational in origin invalidates the use of the one time sectional study approach in collecting data in the asbestos products industry for correlating effects of the working environment on health This study will require the establishment of base line data and following this on a prospective plan until an adequate exposure time has been covered
In outtl he pli an ofn stude y outld ined in the protocol it is plantonesetad b-
lish pnewpdeypen. thet will facilitate the collection of base line data from which

and establishing the nature and extent of pertinent plant exposure for each in-
dividual throughout als employment in the industry Mortality rate and causes

Environmental data characterizing the nature and extent of plant posures will be obtained in each participating plant as outlined in the protocal This data will be collecbty etdhe Public Health Service with assistance when available from state and local occupational healta agencies
B. Employes The entire plant employment of each participating plant will be included in the cohorts The following information will be obtained
for the Public Health Services on each individual I may be collected
on a established basis by trained and competeat personnel of the medical department of the plant or by state or local occupational health agencies or by the Public health Service

spective data will be added until twenty to thirty years of retrospective and

Dr. Kenneth Smith - GHQ
Today I talked to Dr. W. L. Wilson Chief Occupational Health Section of the North Carolina State Board of Health in regards to the engineering and medical study planned
by the Public Health Service
This is the matter that you and ir Sheckler discussed with
Dr. Wilson during your visit with him last December and were in accord in participating in this survey
This survey is tentatively scheduled for the Marshville Plant for the period of May 15 and will be purely an environmental study covering extended dust counts humidity
and air flow and the usual annual visit of the mobile ray unit
Dr. Wilson pointed out that on this visit the Public Health Survey Unit would not become involved with individual histories of our employees but that this would probably be incorporated in their visit next year
