Vinyl Chloride Cancer Mechanism

Since that time new data have become available which have been incorporated in this monograph and taken into consideration in the present evaluation.

Vinyl chloride cancer mechanism.

Vinyl chloride is used primarily to make pvc a substance used in products such as pipes. There is strong evidence from both human and animal studies that vinyl chloride causes cancer via a genotoxic mechanism. Studies of long term exposure in animals showed that cancer of the liver and mammary gland may increase at very low levels of vinyl chloride in the air 50 ppm. 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.

About 13 billion kilograms are produced annually. It also has other toxic effects on the liver and it has recently been suggested that exposure to vinyl chloride also causes. Learn about vinyl chloride which can raise the risk of a rare form of liver cancer as well as brain and lung cancers and leukemia and lymphoma. Discovered in 1835 it is used as an intermediate in the production of polyvinyl chloride pvc which is molded into pvc piping and bottles.

Brain cancer lung cancer and some cancers of the blood also may be connected with breathing vinyl chloride over long periods. In the 1970s epidemiologists found that workers in factories using vinyl chloride the key ingredient for pvc plastics had unusually high rates of a rare form of liver cancer called angiosarcoma. 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 an organochloride flammable gas with a sickly sweet odor which is a colorless at ambient temperature.
