bioaccumulate. . .these chemicals dominate virtually all government lists of priority

pollutants” [Ref. 8]. Below is a discussion of several of these chlorinated compounds.

Dioxin (Polychlorinated Dibenzo Furans (PCDF) and Polychlorinated Dibenzo

Dioxins (PCDD)) is a chlorinated organic compound. It is a byproduct of vinyl chloride

manufacture and can be produced from trash barrels, coal fired utilities, wood burning,

metal smelting, and diesel trucks. “Dioxins do not break down to any appreciable degree

in the environment; virtually all the tetrachlorodi-benzo-p-dioxin (TCDD) released in the

environment will remain there…indefinitely” [Ref. 8]. The National Toxicology Program

has classified dioxin as a known human carcinogen [Ref. 11]. It bioaccumulates in

tissues because as an organochlorine it is more soluble in oil and fats than they are in

water. Exposure can cause chloracne, diabetes, and cancer, which has been shown in

laboratory animals.

Polyvinyl chloride production is also a hazardous process, and the workers have a

high risk of an occupational exposure if they do not take the proper safety precautions.

“In the late 1960s, Dr. John Creech and Dr. Maurice Johnson were the first to clearly link

and recognize the carcinogenicity of vinyl chloride monomer to humans when workers in

the polyvinyl chloride polymerization section of a B.F. Goodrich plant near Louisville,

Kentucky, were diagnosed with liver angiosarcoma, a rare disease” [Ref. 12]. Vinyl

chloride is a human carcinogen as shown by the International Agency for Research on

Cancer [Ref. 13].

Another chlorinated compound is chloroform, a volatile chemical which can be

found in any chemistry laboratory. At 990 ppm, exposure can result in dizziness and

fatigue, and the vapors can depress the central nervous system. Liver and kidney damage
