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...
متن کاملVinyl 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 کاملMutagenicity studies of vinyl chloride.
Mutagenicity studies in both man and in test organisms clearly demonstrate positive mutagenic activity of vinyl chloride. In terms of the mutagenicity studies using a variety of in vitro procedures covering both eukaryotes and prokaryotes, positive effects were found. Cytogenetic in vivo studies in animals and in humans indicate not only somatic mutations, but also germinal effects with this ch...
متن کاملEffect of some additives on degradation of poly (vinyl chloride- co- vinyl
The thermal decomposition of 86 % vinyl chloride 14 % vinyl acetate copolymer wasstudied by the conductometry technique in the presence of nitrogen. The kinetics of stability andthermal degradation of vinyl chloride- co- vinyl acetate (PVC- co- PVAc) copolymer withcopper, copper oxide and tricalcium dicitrate (st) were investigated at various temperatures (150-180 oC ) in solution. The rate coe...
