United States Environmental Protection Agency EPA530-R-08-001 February 2008 National Priority Chemicals Trends Report (2001-2005) Section 4 Chemical Specific Trends Analyses for Priority Chemicals (2001-2005): Priority Chemicals (PCs) Not Reportable to TRI Hazardous Waste Minimization and Management Division Office of Solid Waste U.S. Environmental Protection Agency Contact Information: Bill Kline, Senior Data Analyst Analysis & Information Branch (540) 341-3631 kline.bill@epa.gov Tammie Owen, Data Analyst Analysis & Information Branch (703) 308-4044 owen.tammie@epa.gov Ben Lesser, Chief Analysis & Information Branch (703) 308-0314 lesser.ben@epa.gov ------- Priority Chemicals (PCs) Not Reportable to TRI Seven of the 31 PCs are not reported to TRI. As such, we currently are unable to analyze the generation and management trends for these chemicals. EPA is continuing to evaluate the potential use of Hazardous Waste Biennial Report (BR) data for future trends analyses of these PCs. We present some information about these PCs, including the CAS number, alternative names, and general uses. To find more information about these chemicals, please go to the following website: http://www.epa.gov/epaoswer/hazwaste/minimize/chemlist.htm Priority Chemicals (PCs) Not Reported to TRI 1,2,4,5-Tetrachlorobenzene Acenaphthylene 4-Bromophenyl phenyl ether Endosulfan, beta-/Endosulfan, alpha Acenaphthene Fluorene Pyrene 1,2,4,5-Tetrachlorobenzene Alternate Names - benzene tetrachloride, s-tetrachlorobenzene General Uses - 1,2,4,5-Tetrachlorobenzene is used as an intermediate or building block to make herbicides, insecticides and defoliants. It is also used to make other chemicals, such as 2,4,5-Trichlorophenol and 2,4,5-Trichlorophenoxyacetic acid. 4-Bromophenyl Phenyl Ether Alternate Names - l-bromo-4-phenoxybenzene, 4-bromodiphenyl ether, p-bromodiphenyl ether, 4-bromophenoxybenzene, 4-bromophenyl phenyl ether General Uses - 4-Bromophenyl phenyl ether is primarily used for research purposes. In the past, it was used as a flame retardant. Acenaphthene Alternate Names - 1,2-dihydroacenaphthene, 1,2-dihydroacenaphthylene, 1,8-ethylenenaphthalene, ethylene naphthalene, naphthyleneethylene, peri-ethylenenaphthalene General Uses - Acenaphthene is used to make dyes, plastics and pesticides. Acenaphthylene Alternate Names - 1,2-dehydroacenaphthalene General Uses - Acenaphthylene is used to make dyes, plastics and pesticides. Endosulfan, beta-/Endosulfan, alpha Alternate Names - hexachloro-5-norbornene-2,3-dimethanol, cyclic sulfite General Uses - Endosulfan is used as an insecticide on crops. It has not been produced in the United States since 1982, but it has been used to make other chemicals. 4-138 ------- Fluorene Alternate Names - 2,2'-methylenebiphenyl, 2,3-benzindene, o-biphenylenemethane, 9H-fluorene, alpha-diphenylenemethane-9H-fluorene, diphenylenemethane General Uses - Fluorene is used to make dyes, plastics and pesticides. Pyrene Alternate Names - benzo[def]phenanthrene, beta-pyrene General Uses - Pyrene is used to make dyes, plastics and pesticides. It is also used to make benzo(a)pyrene. 4-139 ------- [Page intentionally left blank.] 4-140 ------- |
