Abstract
During thermal processing of shale, the air constantly contains benz (a) pyrene in concentrations that generally do not exceed the MAC (Maximum Allowable Concentration). In experiment, however, benz (a) pyrene was found to produce a carcinogenic effect when present in a concentration as low as tenths or even thousandths of one percent. The possibility of direct contact of workers with shale products was explored. It was found that standardized rates of malignant tumors of the skin were increaed among workers with a considerable length of service at shale plants. Preventive measures are proposed.
