Worker exposure to vinyl chloride and poly(vinyl chloride).
The National Institute for Occupational Safety and Health (NIOSH) in early 1974 began industrial hygiene studies of vinyl chloride exposed workers. Three VC monomer plants, three VC polymerization plants, and seven PVC fabrication plants were surveyed. V polymerization plant workers and workers in one job category in VC monomer plants were exposed to average levels above 1 ppm. The highest aver...

15 صفحه اولVinyl chloride Toxicological overview
Vinyl chloride is readily and rapidly absorbed via inhalation, ingestion and through the skin At room temperature vinyl chloride is a gas, so inhalation is the major route exposure Following absorption, it is distributed through the body, with the highest concentrations found in the liver and kidneys, followed by the lungs and spleen Vinyl chloride is mainly metabolised in the liver int...
متن کاملVinyl Chloride General information
Toxic by all routes of exposure – inhalation, ingestion, skin contact Carcinogenic in humans Inhalation of vinyl chloride causes coughing, wheezing and breathlessness, headache, ataxia, drowsiness and coma Ingestion of vinyl chloride causes nausea, vomiting, diarrhoea, abdominal pain, and haematemesis may occur. Skin contact causes irritation, pain, burns and contact dermatitis. Rapid...
متن کاملEffect of ethanol on vinyl chloride carcinogenesis.
Four treatment groups (80 male Sprague-Dawley rats/group) were used in a 2 X 2 factorial design: inhalation of 600 ppm vinyl chloride (VC) 4 hr/day, 5 days/week for 1 year; VC and ingestion of 5% ethanol in water (v/v); filtered air and ethanol; filtered air. Ingestion of ethanol was begun 4 weeks prior to inhalation of VC and continued for life or termination of the study at two and one-half y...
