An epidemiologic survey of lung cancer deaths among curing press operators at Uniroyal, Incorporated (SIC-3069) in Mishawaka, Indiana was conducted on December 2, 1980. The investigation was requested by an authorized representative of the United Rubber Workers International Union on behalf of 162 Fuel Cell Division workers including 3 curing press operators. Bulk air samples were analyzed to determine process emissions and nitrosamines. The medical findings of a study conducted by the University of North Carolina concerning lung cancer rates among the exposed workers were reviewed. Air sampling revealed N-nitrosodiphenylamine (86306), N- nitrosomorpholine (59892), dimethylnitrosamine (62759), and diethylnitrosamine (55185); no exposure limits are provided, but evidence exists indicating the carcinogenic potential of nitrosamines. No excess incidence of lung cancer was found among Uniroyal workers as compared to the general population, or among Fuel Cell Department workers as compared to workers in other departments. The authors conclude that no excess lung cancer risk exists for curing press operators; however hazardous exposures to nitrosamines, which are suspected carcinogens, are present. They recommend evaluation of nitrosamine exposures and use of local exhaust ventilation.
