Cummins and E.M. Williams The adsorption power of various J.

Hickey Div of Indust Hyg State Dept. of Public Health Providence 1938 The jewelry industry in Rhode Island comprises 289 plants employing 10,315 workers about half of whom are women More than half of the plants onploy loss than 10 workers It was found that 8912 or 88 per cent of the number were not exposed to any hazardous material or process in any manner and the percentage of those exposed to any degree at all was vory small 0.28 per cent A few 436 or 4.8 per cont were engaged in electroplating work and the seriousness of their exposure is questioned pending further investigation SEVERAL TOXIC VOLATILE INDUSTRIAL SOLVENTS 1189 July 19 1938 Belgian D. Glibert Bruxelles 18 Because physicians are likely to encounter some of the growing number of toxic industrial solvents the author discusses a few of them in this paper and lists others which are cither not discussed at length or are otherwise generally well known Attention is especially called to the chlorinated hydrocarbon group He stresses particularly that the solvents as used ore rarely pure and that this fact should be taken into consideration along with other factors such as the origin of the solvent its instability and the particular conditions of its use in the plants 125 SOLVENTS AND THEIR DANGERS 1938 German Wenzel Zontr.Goworbehy2g5 217-24 J Industrial solvents are classified as to their general use o.g. viscosity changers plasticizers azeotropic mixtures cxtractants degreasers solvents for solids impregnators pharmaceuticals and carriers for other materials Many examples are given The flammability physiological action origin and industrial use of many solvents are discussed Special attention is given to spray booth design and exhaust paints and lacquers and solvents used in tho rubber and textile industries The most important phase of worker protection is adequate education as to the danger and proper handling of the solvent in question 126 EVALUATION OF THE ODOR NUISANCE IN THE MANUFACTURE OF KRAFT PAPER J.M.

Orenstein Johannesburg So. Africa This report deals with the various activities of the Department particularly with the health conditions of the native labor force employed in the gold mines of the Witwatersrand The total mortality from all diseases for the year has reached the record low level of 6.82 per 1000 and mortality due to accidents was 1.97 per 1000. The principal disease is pneumonia the mortality rate for which was 2.60 per 1000. Although the pneumonia rate still remains high a notable improvement has been achieved when it is noted that the mortality rate for this disease in 1911 was 13.0 per 1000. An analysis taking into account meteorological conditions shows that the highest incidence of pneumonia is during seasons of low temperature and high wind velocity The incidance of pulmonary tuberculosis has also been reduced notably In 1915 the rato was 12 per 1000 and in 1937 was 1.84 per 1000. At the same time the mortality rate for the disease has dropped from 1.48 to 0.43 The Department maintains 11 hospitals rescuc training stations and supplies the workers with adequate fully cooked . rations 267 TUBERCULOSIS IN INDUSTRY G.C.

Klotz Am Cancer 35 38-49 January 1939 In support of the view that inhaled dust particularly silica may play a J. part in the production of primary carcinoma of the lung the author presents 4 cases MWBB of bronchogenic carcinoma observed in an autopsy series of 50 silicotic subjects The incidence of % obtained in this serios is compared with that of 1.7 in control group of 4,500 routine autopsies performed during the years 1925-36 At first sight it appears that this is very strong suggestive evidence that silica plays a significant role in the otiology of pulmonary cancer but it should be pointed out as the author admits that it is not statistically accurate to compare so small a group of silicotics to so large a group of controls Other studies previously reported from the Saranac Laboratory South Africa and Europe show incidences of 0.73 0.70 and 0.93 respectivoly the latter among men with no dust history at all The conclusion is made that it does not seem justifiable to implicate the inhaled dust as a carcinogenic agent even though the author has attempted to eliminate other causes It is suggested that heredity may play a part INDUSTRIAL DUSTS AND THE MORTALITY FROM PULMONARY DISEASE A.J. Lanza and R.J. Vane Am Rev. Tuberc 39 419-39 April 1939 Early occupational mortality studies focussed attention on the importance of dust as a cause of respiratory diseases Virtually all kinds of dusts were implicated Present day clinical and laboratory studies point to the serious damage to the lung tissue caused by a few dusts notably silica and asbestos and to the relatively little damage to the lung tissue caused by many other dusts Tho death rates from tuberculosis among men in occupations in which there is exposure to free silica so exceed those found for men in other occupations as to leave littlo doubt that silica is implicated American mortality for silicate other inorganic dusts are very meagre British records are more complete there is doubt as to their true accuracy There is little or no data on and but men ex- posed solely to metallic dusts Recent statistical studies show higher than average rates for tuberculosis among men exposed to organic dusts but they are not nearly as high however as in exposure to silica dust The relationship between dust inhalation and acute pulmonary disease remains a good fild for further investigation 349 TUBERCULOSIS IN INDUSTRIAL WORKERS D.E Cummings R.N. Downs and M. Berg An Rev. Tuberc 39 439-55 April 1939 The field division of the Saranac Laboratory has determined the incidence of tuberculous lesions recognizable in good stereoscopic chest roentgenograms propared on large groups of workmen engaged in several industries located in various parts of the United States The incidence of tuberculous lesions has been shown to increase with advancing age rising among steel workers from about 1.0 at ages less than 20 years to 12.5 for ages from 65 to 74. Evidence which should have a bearing on frequency of industrial physical examinations has been presented which suggests that the rise in incidence with age is due to the development of new infections at all ages Approximately two new cases of pulmonary tuberculosis appear to have developed each year per 1000 white male steel mill workers and seem to have developed at any age with the same facility The article presents an excellent discussion of the statistical elements of tubercu- losis incidence in industry 199292 1992 1992 1992 November November November NovemberNovember November November November November November November November November November November November November November t ABRAME ABRAME ABRAME ABRAME ABRAME ABRAME ABRAME ABRAME ABRAME ABRAME ABRAME ABRAME ABRAMEABRAME KKE E KEKE KE KE ONON ON FOUNDATION FOUNDATI FOUNDATION FOUNDATION FOUNDATION FOUNDATI FOUNDATI FOUNDATION FOUNDATION ; September 1939 This letter is issued monthly to member companies and trade associations affiliated with Air Hygiene Foundation Its purpose is to repor Foundation news and activities Air Hygien industry Foundation is a science organized partnership of to protect the health and of -00081 15 million workmen in heavy industry -0 081 NO HWBB Are You Missing Any Bets A safety engineer in a company affiliated with Air Hygiene Foundation was recently obliged to design some exhaust equipment He spent much time and effort looking up data none of which proved very helpful After the installation was com- pleted with considerable difficulty -- the engineer chanced upon two of the Foundation's engineering bulletins Design of Exhaust Hoods and Design of Duct Work for Exhaust Systems He complained Why didn't somebody tell me about these bulletins Why they're exactly what I wanted The bulletins were available in his organization all the time gathering dust know on someone's shelf The his company was a member engineer didn't know such of the Foundation didn't bulletins know what existed services didn't the Foundation affords Costly cases such as this are all too common Dr. H.B.

George and R.D. Loonard Radiology 33 196-202 - August 1939 The authors discuss some of the conclusions they have reached after an oxtensive experience examining asbestos workers Each industry or occupation should be studied by itself because the hazards of each vary greatly The most important variable with occupation is the percentage of free silica in the dust which can cause the development of a silicotic condition in addition to the asbestotic one The authors are of the opinion that asbestosis is not a progressive disease after the individual has been removed from the dust hazard They found also that the disease has no causal relation to tuberculosis Unlike silicosis ray appearance of tuberculosis and asbestosis are quite different They found no clinical findings pathognomonic of asbestosis and state that diagnosis of asbestosis must depend alone on ray evidence 631 PULMONARY ASBESTOSIS V.

Electron Electron Microscopy on Asbestos Dust and on Lungs in Asbestosis J. Kuehn Arch.f.Gewerbepath Arch.f.Gewerbepath 10 473 April 16 1942 German The author reports some microscopic studies of asbestos and of lungs of asbes- tosis victims for the purpose of determining what variety of asbestos is responsible for asbestosis Serpentine chrystolite asbestos is the form generally used and it was supposed that it would be found in lungs with asbestosis Sundius and Bygden disclosed however that only hornblende asbestosis is demon- strable in the lungs suggesting that serpentine dust is decomposed in the tissues The author used the electron microscope to study the form size and structure of asbestos both in free dust and as found in the lungs It is usual- ly easy to distinguish the two forms under the electron microscope the serpentine variety being generally curved clear and transparent and hornblende rigid and greater in diameter However examination of the particles from 3 lungs did not indicate clearly what variety was present The photomicroscopic determina- tion of the refraction exponent suggested by Sundius and Bygden was then em ployed That method revealed that the large asbestos needles isolated lungs were of the hornblende type It is concluded that serpentine asbestos the is asbestosis decomposed in the lungs and is the essential cause of fibrosis When lungs are macerated with nitric acid and hydrogen peroxide both free stos needles and asbestosis bodies are obtained Hornblende asbestos shote no signs of decomposition by the organism either in the free needles or on the asbesto- sis bodies of 481 Polarigraphic Determination Lead in Bones E.

It appears to be impossible to destroy anthrax at its source Sporadic cases of hides native origin will always occur It is extremely difficult to disinfect and skins The anthrax spore undoubtedly survives the first two or three processes in tanning -- that is washing fleshing and liming -- but probably can not survive the entire process No significant improvement in the method of killing anthrax spores has been evolved in the last twenty years and even if it were possible to disinfect hides and skins it is doubtful whether this would be warranted especially at the present time Therefore the method of control must be chiefly one of education and sanitary precaution until the hides have passed through the tanning process The more severe cases and the most frequent deaths have occurred in truckmen and longshoremen who are not aware of the possibiliti of this infection and who neglect to report for treatment early The prompt diagnosis and treatment in tannery workers seen in large measure responsible for the lessened mortality and morbidity among them Physicians treating eous infection in a tamery worker or truckman should bear in mind the order te of anthrax disease in and should culture check effectively material from the lesion In an educational program must be truckmen tannery workers longshoremen and all others who hands from their arrival in this country to their conversion into finished Authors summary 663 664 In Med.
