D. L. Block, M. D.J Director of Employe Health Services, Personnel and Organi
zation Staff, and E. Eichen, Manager of Central Laboratory Services, had dis
cussed with Professor Irving J. Selikoff of Mount Sinai the possibility of
some degree of Ford assistance in this investigation* A meeting, arranged by Drs. Block and Selikoff to pursue this further, was held on March 1.
Present from Mount Sinai were Drs. Arthur M. Longer and Duncan Holliday.
Present from Ford, in addition to Drs. Block and Eichen, were P. E. Toth and L. Roslinski of Employe Health Services, and A. E- Anderson and R. L. Gealer
of Scientific Research Staff.
The Mount Sinai people indicated that their objective is to sample
and examine qualitatively and quantitatively (for asbestos and other materials)
the particulates suspended in the air of brake maintenance shops in New York
City and to establish the degree of hazard involved through blood analysis,
radiographic, morbidity, and mortality studies of an identified group of
workers. While they have sampled and plan to sample the air in a large number
of shops, only a few samples have been examined t o date. Results were pre
sented of a preliminary examination for asbestos of filters which sampled
the air during (l) the cleaning of sun old brake assembly and (2) the grinding
of new brake linings. Examination b y optical microscopy using the procedure
specified by the National Institute for Occupational Safety and Health (NIOSH)

method counts only fibers greater than 5 microns in length. Examination of
these samples was also performed by transmission electron microscope (TEM) at
Lr.OC'X using t:f pr* .e;nre developed at Mount Sinai (low temperature ashing of

t 0.5-1.0 microgram asbestos/cu. m of air for the first sample and 30-1)0 nrLcro-
gram/cu. m for the second (note the different units). The level of asbestos
in the ambient air of New York City has been measured in the range of 0.001-0.1
microgram/cu. m.
The Mount Sinai people vere particularly interested in learning about the other possible constituents of brake dust, e.g., lead, to guide their studies of health effects on the workers. We provided information on the kinds of substances which could be present, stressing that while nearly 11 brake linings contain crysotile asbestos, the other constituents vary with formulation and thus while a given material may be present at times, it may not be present in the air sample from a particular few brakes. We indicated that brake wear dust may contain not only ingredients initially present in the linings, but also organic and inorganic substances created as a result of chemical reactions of constituents at the rubbing interface, e.g., forsterite forms as a decomposi tion product of crysotile asbestos. Iron, iron oxide, and road dust also would be present.
We stated that it would be preferable to classify the workers according to operations performed, since the amounts and types of exposure should be dif ferent in cleaning old brake assemblies, handling new linings and grinding new linings to size.
The main interest of the Mount Sinai representatives at this meeting appeared to be to gain information to guide their medical evaluations of brake workers -- no specific active participation by Ford was suggested.

Subject: SRS Research Grant -- Mount Sinai School of Medicine, City University of New York
Elis grant is being utilized in an investigation of possible health hazards associated with respirable particles of asbestos and other substances to which workers in brake maintenance shops may be exposed. The study includes the com piling of morbidity and mortality experience with such workers (and will include clinical examinations), and the quantitative characterization of the brake dust and work environment.
Some results obtained to date are described in the attached informal report provided by Arthur M. Langer, Associate Professor of Mineralogy at CUNY. They plan to continue the clinical studies and extend the dust characterization to the substances which are present other than asbestos.
Investigators participating in this work (besides CUNY staff) include Dr. Mary Wolf, post-doctoral student working in electron microscopy and instru mentation; Robert Klimentidis, graduate student working in mineralogy and instrumentation; and Joan Humphries, undergraduate student helping with sample preparation.

Brake-Drum Decomposition Products-Current Research Areas March, 197H - March, 1974
The Environmental Sciences Laboratory is currently studying asbeBtos
exposure in workmen who repair and service brake-linings. Although the
area of investigation focuses on passenger vehicles, we are also in
corporating studies Involving large-passenger and commercial-type vehicles
as well. It is the purpose of this research to obtain information regard
ing asbestos exposure in the automotive maintenance and repair, specifically
among men repairing brakes.
We will simultaneously conduct retrospective and prospective health
studies on such Individuals. We are now gathering data concerning past
morbidity and mortality experience. Workmen currently employed in these
trades will be examined clinically and followed to determine prevalence
and incidence of specific diseases. A cohort of these workmen is currently
being developed by our research group.
In addition to the human disease experience, we will also include
-
quantitative characterization of their work environment. Work in this
area is currently being done. We have obtained data concerning light
microscopic-electron microscopic characterization of dust aerosols liberated
from such repair work. We have determined already that, in some instances,
a light microscopic observation indicating no asbestos present in the
atmosphere may actually conceal sevt.al micrograms of asbestos fiber.
These particles are visible only by electron microscopy. We are presently
characterizing the environments created during the removal of old brake
drums, l.e., "blowing-off" of decomposed brake-shoe dust and the refitting
of brake-shoes onto drums by means oi grinding techniques. We have dust
counts of the ambient environment, in such localities before, during and
after brake maintenance and repair. Some of these levels approach and com
pare with occupational exposures to asbestos. In addition to the characterization oi the atmosphere in this envlron-
000239

nent, we are characterizing the recovered dust as well. The mineralogical characterization of such materials has been underway for the past year and some interesting information has been already gathered. Some of these are: some asbestos fiber does survive the braking cycle; in some fibers, although the morphology of the asbestos is retained, it appears to be physically degraded; selected area electron diffraction patterns Indicate a great amount of "disorder" in surviving fibers suggesting an interfibril rotation of Individual units; a host of other materials are present in the brake-drum dust which Include a range of silicate phases, only some of which are apparently "crystalline" ; other materials are present in the dust which are presently uncharacterized. We are currently, and will in the future, characteri^^hese materials by means of electron beam Instrumentation.
On the basis of a careful literature search we are convinced that the focus of disease risk, which may be present in individuals exposed to disintegrated brake-drums, should not be centered primarily on the asbestos as an agent. It is apparent that the brake-drum dust consists of a number of silicate phases in addition to a number of inorganic materials Incorporated as "modifiers". Some of these e;g. lead compounds, may have profound biological effects. Exposure to brake-drum dust may Include possible hazards from asbestos, other silicate forms, modifying compounds, as well as the organic binders. Therefore, clinical work-ups of Individuals exposed to brake-drum dust will have to take into considera tion a number of interacting agents.

Subject: Exposure of Brake Maintenance Shop Workers to Brake Dust
On April 11, 1975, I received a telephone call from Prof. Irving J. Selikoff, Mount Sinai School of Medicine, City University of New York, regarding their investigation of possible health hazards associated with respirable particles of asbestos and other substances to which workers in brake maintenance shops may be exposed. He indicated that their examination of brake shop workers is turning up some dis turbing findings relative to health effects (he didn't elaborate) and that some physicians out West had found brake shop workers well repre sented among lung cancer cases.
Prof. Selikoff would like to discuss these medical findings with appropriate representatives from the automobile companies and Johns-Manville Corp. at a private meeting in New York in the near future. He therefore asked that his invitation and intention to have such a meeting be brought to the attention of interested parties at Ford.
