Carcinogens in Rubber Production in the Soviet Union
並列摘要
In a preliminary phase of a broad research project on cancer among workers in a rubber footwear plant in Moscow, exposure to several known or potential carcinogens was assessed. There were high dust content s bearing both toxic substance s and carcinogens. The highest concentrations of benzo [a] pyrene (500-14400 μg) were found on the soot used as a filler, and the maximum N-dimethylnitrosamine (DMNA) level was measured in thiram (150-23868 μg•kg^(-1)). Air samples from the vulcanization process and the pressing of rubber goods showed BaP levels of up to 1.43 μg•m^(-3). In the work area where polyvinyl chloride was used, the mean vinyl chloride concentration was 0.21 (SE 0.06) mg•m^(-3) The mean value of the acrylonitrile concentrations in the workroom area was 0.19 (SE 0.07) mg•m^(-3) Very high levels of DMNA and N-diethylnitrosamine were measured in the preparatory shop in the winter.
