There is some expectation that congressional pressure may lead to studies of vrork safety and health among migrant farm workers. ,, Studies on low-level exposure are underway in BCSH, dealing with uranium, coal dust, carbon monoxide and benzene.

There is no information available to in dicate whether this mode of asbestos penetration can lead to subsequent malignant change in distant organs and skin cancer has not been recorded as a complication of asbestos warts.

This is done in a closed system, although leaks or breaks in the process may lead to transiently high exposure levels.

., lead compounds); they act as "friction agents" increasing the coefficient of friction and enhancing the braking action of the shoe (e.g., brass chips); they act as internal "abrasives," which help to "recondition" the braking surface and remove deposited de composition products (e.g., rottenstone, quartz); they act as "heat sinks," reducing binder pyrolysis and fiber de composition thereby extending the useful life of the lining (e.g., brass chips, metals, etc.). 8005 1870 fZQ PRODUCED BY FORD I1 It is Important to note that one major purpose of the reconditioning agents la to retard the formation of forsterite (a mineral not originally present in the brake material, but created by dehydroxylntion and re- crystallisation of chrysotile asbestos at high temperatures) which may y y y' accumulate on the surface of the brake lining.

However, other assumptions consistent with these data could lead to a predicted risk an order of mag nitude higher than 1% following 50 years' exposure at 2 fibrcs/cm3.
