Priority pollutants, Environmental Protection Agency

Health nd Safety Factors. Isophorone is considered moderately toxic by ingestion and skin contact. Some rat tumor formation evidence has been found (264), but no demonstration as a human carcinogen has been proven. Isophorone is considered an Environmental Protection Agency (EPA) priority pollutant, and has a permissible acute toxicity concentration of 117, 000 ///L to protect freshwater aquatic life, 12, 900 ///L to protect saltwater aquatic life, and 5, 200 ///L to protect human life (265). Isophorone is mildly toxic by inhalation, but because of its low volatiUty it is not a serious vapor hazard.

Among all chlorophenols, 2,4,6-trichlorophenol (TCP) and pentachlorophenol (PCP) are listed as priority pollutants by the US Environmental Protection Agency (EPA) (IRIS electronic database) and the EU [256]. In particular, PCP has been classified as a B2 probable carcinogen for humans from animal toxicity studies and human clinical data. 

Keith et al. [36] and Reijnders et al. [37] reviewed applications of gas chromatography-mass spectrometry to sediment analysis. Lopez-Avila et al. [38] investigated the efficiency of dichloromethane extraction procedures for the isolation of organic compounds from sediments prior to gas chromatography-mass spectrometry. The compounds investigated were the 51 priority pollutants listed by the Environmental Protection Agency, USA.

The ubiquitous nature of these airborne PAHs is evident from the fact that the 16 U.S. Environmental Protection Agency Priority Polycyclic Aromatic Hydrocarbon Pollutants shown in Table 10.1 (U.S. EPA, 1988) are found, as we shall see in this chapter, in urban airsheds throughout the world. Their widespread...
