Asbestos in brake worker's lungs: an exposure index.
Mount Sinai School of Medicine, 1979 Aug; :1-10
The presence of asbestos (1332214) bodies in the lungs of brake maintenance and repair workers (SIC-7539) was evaluated as an exposure index. Lung tissue specimens from various lung areas were obtained at autopsy for 100 brake workers. The positive comparison group included construction workers, shipyard personnel, pipe coverers, steam fitters, and rubber workers. The negative comparison group consisted of white collar workers, professional workers, and housewives. The number of asbestos bodies in the lung parenchyma of brake workers was similar to that in the negative control group. Among the brake workers, a positive correlation existed between the number of years on the job and the number of thin fibers in the lung, while a negative correlation existed between age a death and the presence of definite asbestos bodies. A relationship also existed between the presence of asbestos bodies and other fibrous objects in lung tissue. For all groups, males tended to have more asbestos bodies than females. The authors concludes that asbestos body and fiber content of the lung is a poor exposure index for brake maintenance and repair workers.
