[Exposure to vinyl chloride in the Polish industry]

Information concerning exposure to vinyl chloride collected in Occupational Hygiene Departments of Sanitary-Epidemiological Stations were verified. On the basis of the studies performed it was found that about 3700-4000 persons in Poland are occupationally exposed to vinyl chloride; 400 of these workers are employed at the synthesis and polymeryzation of vinyl chloride, and the others at plasticination and processing of polyvinyl chloride. About 200 workers employed in 3 plants of vinyl chloride polymerization and synthesis and about 30 employees of one of the plants processing this compound are exposed to vinyl chloride whose concentration exceeds the hygienic standard accepted in Poland (30 mg/m3).
