Cancer rubber industry workers

The presence of carcinogenic compounds within the rubber industry has been a controversial issue in the field of occupational medicine (Conde-Salazar 1987, 1990a). Both 1,3-butadiene and styrene, which are used extensively in synthetic rubber, are known carcinogens (reviewed in Fishbein 1992). Significant levels of butadiene (0.06-39 Ppm [National Institute for Occupational Safety and Health 1984 International Agency for Research on Cancer 1986 de Meester 1988]) and styrene (2.4 ppm [World Health Organization 1983]) can be found in factories where these synthetic rubbers are produced however, due to automation and safety precautions, workers are not routinely exposed to...

Rubber and Tire Industry. Fajan et al (40) showed that N-nitrosomorpholine, and to a lesser extent. NDMA, were present as air pollutants inside a tire factory and a factory where chemicals for the tire industry were being manufactured. The N-nitrosomorpholine levels varied between 600 and 7,200 ng/m3. The results may be relevant to recent epidemiological studies (41) which reptort an increased risk of certain typ>es of cancer in workers in the same areas of the tire factories where we found the highest N-...
