Vinyl Chloride 75-01-4 _____ Hazard Summary . Water Treatment for Vinyl Chloride. What Does Vinyl Chloride Do to Your Body Individuals who were exposed to vinyl chloride-contaminated drinking water may experience central nervous system effects and liver damages. Polyvinyl Chloride (PVC or Vinyl) is an economical and versatile thermoplastic polymer widely used in building and construction industry to produce door and window profiles, pipes (drinking and wastewater), wire and cable insulation, medical devices, etc. (1983). VINYL CHLORIDE VCM CAUTIONARY RESPONSE INFORMATION Common Synonyms Gas Colorless Sweet odor Liquid floats and boils on water. Vinyl chloride the starting material from which PVC polymer is made, has a Henry's-law constant of 0.091 at 25 C. What is the solubility of vinyl chloride in water (in MOL/L) at 25 and a partial pressure of 0.55 ? PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible. The electrolysis of salt water produces chlorine. They evaporate easily and form toxic, explosive mixtures. Linear Formula H 2 C=CHCl . Most vinyl chloride is used to make polyvinyl chloride (PVC) plastic and vinyl products. According to the Australian Drinking Water Guidelines, no safe concentration for vinyl chloride in drinking water can be confidently set. What is Vinyl Chloride and How Did it Get in My Water?/span> Many people suffer from the effects of various water contaminants in their water supply. 1. The Office of Environmental Health Hazard Assessment (OEHHA) has developed a public health goal (PHG) of 0.05 mg/L (or ppb) for vinyl chloride in drinking water. What is vinyl chloride? Vinylidene Chloride Polymers. Drinking contaminated water can expose you to vinyl chloride; however, the most common way people are exposed is through breathing contaminated air. An outlet water that contains 0.1 ppm (molar) vinyl chloride is required. Vinyl Chloride - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Risk assessment and hazard evaluation activities relating to chemical contaminants in drinking water CalEnviroScreen Explore CalEnviroScreen, a mapping tool showing communities affected by pollution In an assessment completed in 2000, California Office of Environmental Health Hazard Assessment stated that drinking water is not a significant source of exposure to vinyl chloride for the general population. Effects of water solubility of acrylonitrile on vinylidene chloride/acrylonitrile/styrene suspension polymerization. Vinyl chloride can also form in the pipes as a result of water disinfection with chlorine. Some vinyl chloride can dissolve in water. Quick links. Molecular Weight 62.50 . Entry into drinking water may result from industrial discharges to source water from chemical and latex manufacturing or from leaching of the entrapped monomer from polyvinyl chloride pipe. However, for practical purposes, the concentration should be less than 0.0003 g/L, which is the limit of determination. Vinyl chloride in water or soil evaporates rapidly if it is near the surface. PUBLIC HEALTH GOAL FOR VINYL CHLORIDE IN DRINKING WATER SUMMARY . When there is a greater flow of water flowing through the pipe, the vinyl chloride is more diluted and the resulting vinyl chloride concentration reaching customers is lower. Vinyl chloride is a colorless organic gas with a sweet odor. Acute (short-term) exposure to high levels of vinyl chloride in air has resulted in central nervous system (CNS) effects, such as … Vinyl chloride in the air breaks down in a few days, resulting in the formation of several other chemicals including hydrochloric acid, formaldehyde, and carbon dioxide. Vinyl chloride can be treated with granular activated carbon combined with reverse osmosis, some distillation methods, and air stripping. Vinyl chloride copolymers and PVC are distributed and processed in a variety of forms, including dry resins, plastisol (dispersions in plasticizers), organosol (dispersions in plasticizers and volatile solvent), and latex (a colloidal dispersion in water used to coat paper, fabric, or leather) (USEPA 1985a).

Vinyl chloride in the air breaks down in a few days, resulting in the formation of several other chemicals including hydrochloric acid, formaldehyde, and carbon dioxide. Vinyl chloride can enter drinking water through leaching of the entrapped monomer from polyvinyl chloride (PVC) pipe. Although the industries that use this chemical have known about the harmful effects of vinyl chloride for decades, it has only recently been identified as a known carcinogen. The resulting element is ethylene dichloride, which is converted at very high temperatures to vinyl chloride monomer. These monomer molecules are polymerized forming polyvinyl chloride … This short paper covers issues that surround the use of microbes in the removal of toxic waste, in particular, the removal of vinyl chloride and dichloroethane.Bacteria have been found that eat toxic waste and could be used to clean up contaminated water under many industrial sites.
