As the nation's health protection agency, CDC saves lives and protects people from health, safety, and security threats. NIOSHTIC-2 Publications Search - - Vinyl chloride and polyvinyl chloride. Vinyl chloride is primarily found in polyvinyl chloride products, one of the most environmentally hazardous consumer materials ever produced, and it is dangerous to human health throughout its entire life cycle of production. Exposure to vinyl chloride has been linked to central nervous system effects and liver damage.
Vinyl chloride is a widely used chemical, most well-known as a material in polyvinyl chloride (PVC) plastic and vinyl products. It has been used for many years in a variety of other commercial and industrial products, though recent studies have concluded that it is highly toxic, and linked to several serious illnesses, including cancer. Vinyl chloride is a Group 1 human carcinogen posing elevated risks of rare angiosarcoma, brain and lung tumors, and malignant haematopoeitic lymphatic tumors. Chronic exposure leads to common forms of respiratory failure (emphysema, pulmonary fibrosis) and focused hepatotoxicity (hepatomegaly, hepatic fibrosis).Appearance: Colorless gas.
LEACHING OF VINYL CHLORIDE MONOMER (VCM): NOT AN ISSUE FOR Polyvinyl chloride (PVC) is produced from vinyl chloride monomer (VCM) through a process known as polymerization, where VCM is transformed into a white powder called PVC resin. Polymerization is a one-way reaction that has the same effect as frying Health Effects” was.

Most vinyl chloride is used to make polyvinyl chloride (PVC) plastic and vinyl products. Acute (short-term) exposure to high levels of vinyl chloride in air has resulted in central nervous system effects (CNS), such as dizziness, drowsiness, and headaches in humans.
Evaluates the risks to human health and the environment posed by exposure to vinyl chloride, a colourless, flammable gas manufactured almost exclusively for use in the production of polyvinyl chloride (PVC).
PVC is used to produce plastic materials having wide applications in the building sector, packaging, electrical appliances, medical care.
Poly (vinyl chloride) (PVC) is a complex plastic system. Individual components of the PVC system, including residual vinyl chloride monomer (RVCM) and certain additives, may pose risks of harm to human health. There have been significant reductions in the RVCM content of PVC resin sincereducing the cancer risk Cited by: Polyvinyl chloride, also known as PVC or vinyl, is a synthetic resin produced from the polymerization of vinyl is an odorless and solid plastic and can come in the form of white powder or pellets.
Next to polyethylene, it is the most widely used plastic in the world. PVC contains chemicals that may have adverse health effects: Exposure to PVC often includes exposure to phthalates and chlorine.
Manufacturing, burning, or landfilling PVC releases dioxins. Phthalates, dioxins, and BPA are suspected to be endocrine disruptors. * This data for Bis(2-ethylhexyl)Phthalate and Vinyl Chloride Monomer apply to the pure form of the compound.
In Polyvinyl Chloride Bis(2-ethylhexyl)Phathalate exist in concentrations less than 1%. The Vinyl chloride Monomer exists in concentrations less than Size: KB. Third, the polyvinyl chloride resins are fabricated into a myriad of finished products.
This step involves a large number of industrial processes. Health Effects. CWA members are most often exposed to vinyl chloride as a result of the inhalation of or breathing the chemical’s vapors.
Economical, versatile polyvinyl chloride (PVC, or vinyl) is used in a variety of applications in the building and construction, health care, electronics, automobile and other sectors, in products ranging from piping and siding, blood bags and tubing, to wire and cable insulation, windshield system components and more.
Uses & Benefits. Polyvinyl chloride (PVC) is an important plastic resin for construction, pipe and tubing, siding, and other uses. Exposures to vinyl chloride monomer during the early years of production resulted in an important sentinel health event: the recognition of an excess of a rare liver cancer, hepatic angiosarcoma, at facilities throughout the by: ‘The harmful health effects of vinyl chloride have been known for decades, though the industry has suppressed and misrepresented the health effects from PVC exposures for years.
Industry experiments in laboratory animals, as early as the s, found evidence of harm but officials did not initially disclose the findings.
Vinyl chloride has a mild, sweet odor, which may become noticeable at 3, parts vinyl chloride per million parts (ppm) of air. However, the odor is of little value in preventing excess exposure. Most people begin to taste vinyl chloride in water at ppm. Polyvinyl chloride (PVC) is a widely used building material praised for its durability, yet criticized for its potential health hazards.
PVC was discovered accidentally in the early 19 th century when the polymer appeared as a white solid inside sunlight-exposed flasks of vinyl chloride. The acute health effects of ingesting vinyl chloride are currently unknown . Vinyl chloride is classified as a “known human carcinogen” by the NTP and the USEPA, and as a Group 1 human carcinogen by the IARC, with known target sites including the liver, lung, and connective tissues [19,].
Vinyl chloride is used primarily in the manufacturing of polyvinyl chloride (PVC) resin, a common plastic used in the fabrication of pipes, packaging materials, and insulation. The worldwide production of PVC is extensive, estimated at 59 billion pounds in 1 At room temperature, vinyl chloride is a flammable, colorless gas that has.
Synonyms for vinyl chloride include chloroethene, chloroethylene, 1-chloroethylene, ethylene monochloride, monochloroethylene, monovinyl chloride, MVC, VC, VCM, and vinyl chloride monomer. The following is quoted from the US ATSDR. Persons exposed only to vinyl chloride gas pose no risk of secondary contamination.
What is vinyl chloride. Vinyl chloride (chloroethene), a chlorinated hydrocarbon, is a colorless gas with a mild, sweet odor. Most vinyl chloride is used in the process of making polyvinyl chloride (PVC) plastic and vinyl products, thus may be emitted from industrial processes.
Vinyl chloride has been detected near landfills, sewage treatment plants, and hazardous waste. This fact sheet discusses possible health risks from exposure to low levels of vinyl chloride typically found in drinking water wells.
September Vinyl Chloride What is vinyl chloride. Vinyl chloride is a synthetic, colorless gas. It burns easily. It is not stable at high temperatures.
Vinyl chloride has a mild, sweet Size: KB. Abstract. Background Althoughsome adverse health effects of exposure to polyvinyl chloride (PVC) are well known, there is limited evidence of its effects on the respiratory system.
Aims To assess the pulmonary effects of exposure to PVC with high-resolution computed tomography (HRCT).Cited by: 3. People may begin to taste vinyl chloride in water at 3, parts per billion (ppb).Vinyl chloride is not easily absorbed by the skin.
How can vinyl chloride affect my health. Most of what we know about the adverse health effects of vinyl chloride comes from studies on male workers in the plastics industry and from animal studies.
Vinyl chloride is used to make polyvinyl chloride (PVC). From production through disposal, vinyl chloride threatens health and contaminates the environment. The harmful health effects of vinyl chloride have been known for decades, though industry has suppressed and misrepresented the health effects from PVC exposures for years.
CHAPTER 1: INTRODUCTION TO POLYVINYL CHLORIDE Polyvinyl chloride (PVC) was first manufactured in Germany in as a robust and lightweight new plastic.
This breakthrough material was brought about to substitute for metals, glass, wood, natural fibers, papers and fabrics. Over 30 million tons of PVC is used around the globe today, both inFile Size: KB. Polyvinyl Chloride (PVC) Polyvinyl chloride (PVC) is a solid plastic material made from vinyl chloride.
It is made softer and more flexible by the addition of phthalates, and can contain traces of chemicals like bisphenol A (BPA).Vinyl chloride exposure is associated with an increased risk of a rare form of liver cancer (hepatic angiosarcoma), as well as brain and lung cancers, lymphoma, and leukemia.
How can exposures be reduced? The U.S. Occupational Safety & Health Administration provides information about exposure limits to vinyl chloride. Selected References.
