Toxicological profile for benzene. Final report

The Statement was prepared to give information about benzene and to emphasize the human health effects that may result from exposure to it. The Environmental Protection Agency (EPA) has identified 1,300 hazardous waste sites as the most serious in the nation. Benzene has been found in at least 743 of these sites. However, one does not know how many of the 1,300 NPL sites have been evaluated for benzene. As EPA evaluates more sites, the number of sites at which benzene is found may change. The information is important to know because benzene may cause harmful health effects and because these sites are potential or actual sources of human exposure to benzene.
