| Summary: | This statement was prepared to give information about 1,3-dinitrobenzene (1,3-DNB) and1,3,5-trinitrobenzene (1,3,5-TNB) and to emphasize the human health effects that may result from exposure to them. The Environmental Protection Agency (EPA) has identified 1,397waste sites as the most serious in the nation. These sites make up the National Priorities List(NPL) and are the sites targeted for long-term federal clean-up activities. 1,3-DNB and1,3,5-TNB have been found in at least 19 of the sites on the NPL. However, the number of NPL sites evaluated for 1,3-DNB and 1,3,5-TNB is not known. As EPA evaluates more sites, the number of sites at which 1,3-DNB and 1,3,5-TNB are found may increase. This information is important because exposure to 1,3-DNB and 1,3,5-TNB may cause harmful health effects and because these sites are potential or actual sources of human exposure to1,3-DNB and 1,3,5-TNB.
