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 کاملCopolymerization of Vinyl Chloride by Organometallic Compounds
ABSTRACT The copolymerizations of vinyl chloride with o-olefin or acrylic compounds were investigated with organometallic compounds as catalysts. In general, organoaluminium compounds need to be treated with a complexing agent such as tetrahydrofuran prior to use. Otherwise the former reacts with polyvinyl chloride and loses its activity. The copolymer of vinyl chloride and propylene was thus o...
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 کاملMolecular mechanisms of carcinogenesis by vinyl chloride.
In 1974 vinyl chloride (VC), a gas used in the plastics industry, was shown to be a human carcinogen, inducing a very rare type of tumor, angiosarcoma of the liver. The same type of tumor was induced in rodents exposed to VC thus providing an excellent model for mechanistic studies. Here, we review the numerous studies on the mechanism of action of VC with particular emphasis on the DNA product...
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...
