Vinyl Chloride Sources

Measured concentrations ranged from trace levels to over 2600 μg m 3 and the average daily intake of vinyl chloride by residents living near such emission sources.

Vinyl chloride sources.

Vinyl chloride is used primarily to make polyvinyl chloride pvc. Vinyl chloride may also enter homes through soil vapor intrusion which occurs when. It can be formed when other substances such as trichloroethane trichloroethylene and tetrachloroethylene are broken down. It does not occur naturally and must be produced industrially for its commercial uses.

About 13 billion kilograms are produced annually. Vinyl chloride is primarily used to make polyvinyl chloride to manufacture plastics. It burns easily and it is not stable at high temperatures. Pvc is used to make a variety of plastic products including pipes wire and cable coatings and packaging materials.

Sources of vinyl chloride in indoor air. Vinyl chloride is a chlorinated hydrocarbon occurring as a colorless highly flammable gas with a mild sweet odor that may emit toxic fumes of carbon dioxide carbon monoxide hydrogen chloride and phosgene when heated to decomposition. Vinyl chloride is used to make polyvinyl chloride pvc. Vinyl chloride is an organochloride with the formula h 2 c chcl that is also called vinyl chloride monomer vcm or chloroethene this colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc.

Vinyl chloride has been used in the past as a refrigerant. Tobacco smoke which contains low levels of vinyl chloride is a possible source for vinyl chloride in indoor air. Emissions and effluents from the plastics industry may be exposed to relatively high concentrations of airborne vinyl chloride. Vinyl chloride is a colorless gas that burns easily.

Vinyl chloride a chemical known to cause cancer poisons the air breathed by workers and people living in contaminated communities. Vinyl chloride is a colorless gas. Vinyl chloride is used to make polyvinyl chloride pvc. The purpose of the national emission standard for hazardous air pollutants neshap is to minimize vinyl chloride emissions from process and fugitive emission sources in ethylene dichloride vinyl chloride and polyvinyl chloride production categories to the level attainable with best.

Populations living near emission sources e g. It is a manufactured substance that does not occur naturally. It has a mild sweet odor.
