[Occupational exposure to chemicals in the manufacture of rubber tires].

The work environment of the rubber industry company, producing various types of tires, was assessed and the workers of the plant were included in a cohort study of mortality. Concentrations of twenty chemical substances at 137 workposts were measured by employees of the plant laboratory and the sanitary and epidemiological station in 1981-1996. The mean values and concentration ranges were determined by departments and workposts. The excess of threshold limit values was analyzed. The workposts with exposure to agents possibly carcinogenic to humans were identified. The analysis performed will render it possible to calculate doses of cumulative exposure to given compounds among workers covered by the epidemiological study.
