sure. Of the compounds identified at more than 100 sites, lead, chromium, arsenic, cadmium, nickel, trichloroethylene (TCE), perchloroethylene (PCE), vinyl chloride, methylene chloride, chloroform, benzene, ethylene dichloride (EDC), and polychlorinated biphenyls (PCB) have been identified as either human or animal carcinogens and are classified in group 1 of the ATSDR-EPA list of the 100 most hazardous substances. A list of agents identified at more than 10 proposed and final NPL sites is listed in Appendix 3-A to this chapter, and the original ATSDR list of priority substances can be found in Appendix 3-B.

Buffler et al. (1985) have reviewed the adverse health effects associated with specific toxicants identified at hazardous-waste sites. While discussing the types of chemicals found, the review addresses whether health effects could be detected in studies of populations exposed to these chemicals at waste-disposal sites.
