PVC products are to the chemical industry what cigarettes are to the tobacco industry: the lynchpin of a toxic economy.(1)
PVC, polyvinyl chloride, is a chlorinated plastic. PVC is made from two carcinogens, ethylene dichloride and vinyl chloride monomer. Production of PVC generates dioxin, a known human carcinogen. Independent studies show that PVC production is among the largest sources of dioxin emissions to the air, land, and water. Also, PVC contains toxic additives such as cadmium, lead, phthalates, and organotins.
Phthalates and organotins are endocrine disrupters. Endocrine disrupters are man-made chemicals which act like hormones, such as estrogen. Endocrine disrupters interfere with normal functions of the hormone systems in humans. Hormones are potent biological substances which act as chemical messengers. Even small amounts can produce large effects. Hormones regulate critical body functions including behavior, development, and reproduction. The endocrine system controls growth, organ development, metabolism, kidneys, body temperature, and other essential functions.
Most endocrine disrupters are fat soluble compounds which tend to remain in the environment, in animals, and people for very long periods. Endocrine disrupters are persistent they are not metabolized by bacteria and they do not degrade well in the environment, and they bioaccumulate they are concentrated in the food chain when humans and animals eat plants and animals containing them.
Polyvinyl chloride (PVC) plastics entire life cycle, from production through use and disposal, has negative environmental impacts. PVC is made from two carcinogens, ethylene dichloride (EDC) and vinyl chloride monomer (VCM). The production of PVC creates large amounts of toxic chemicals, including dioxins, furans, PCBs, and hexachlorobenzene. (2)
The PVC industry has been plagued by worker health and safety issues for decades. The industry was aware of health problems among PVC plant workers, including high rates of cancer, for decades before that information was shared with regulators or workers. The industry spent years using public relations and manipulating science in order to avoid disclosure and liability for worker illness and deaths. A Federal Court has noted that, The record shows what can only be described as a course of continued procrastination on the part of industry to protect the lives of its employees. (2)
PVC is widely used to make building materials, pipes, furniture, and automobile components. When PVC is burned in a fire it gives off toxic hydrogen chloride gas which turns into hydrochloric acid on contact with moisture in the lungs. PVC is involved in a large portion of the approximately one million building and automotive fires in the U.S. each year. Combustion of PVC in accidental fires may be a significant source of dioxin in the environment. (2)
When PVC is burned in medical waste and garbage incinerators, it is among the largest single sources of dioxin in those burners. Extremely toxic heavy metals in PVC, such as lead, cadmium, and chromium, are also released from the stacks and end up in the ash of these incinerators. (2)
PVC ingredients and their toxic by-products have contaminated the air, soil, and water of communities on the Gulf Coast of Louisiana and Texas where the industry is concentrated. (2)
Studies in Netherlands, Sweden, and Germany have all found elevated levels of dioxins in wastewater discharges, sludge, and sediments at PVC production facilities. Greenpeace collected samples from nine US plants that produced EDC or VCM. Four samples were analyzed for dioxin and 25 for other substances used in the production of these chemicals. They found that:(2)(3)
Virtually all of the products made of PVC have safer substitutes available, making the risks posed by PVC completely unnecessary and unacceptable.(2)
1. Reduce and eliminate production and use of PVC to zero. Give priority to uses that are incinerated or burned in accidental fires, and those most easily replaced with safe, non-toxic substitutes. More rapid phase-outs should occur for PVC used in packaging, childrens toys, medical supplies, and construction materials.
2. Phase-out existing PVC plants
3. Permit no new facilities
4. Phase-out and eliminate burning PVC waste in incinerators
Ensure a Just Transition for Workers
A tax during phase-out on the production of EDC and VCM would help drive the transition away from PVC and would finance the costs associated with it. The revenues would be used to ensure a just, equitable, and orderly transition for workers. For example, funds could be used for new job training, income protection, health insurance, and research and development of non-PVC alternatives.(1)
