The increasing contamination of freshwater systems by anthropogenic chemicals is a growing global concern. Among the target non conventional pollutants, Polyclycic Aromatic Hydrocarbons (PAHs) constitute a major issue due to their toxic, mutagenic, carcinogenic, teratogenic and endocrine disrupting properties which make them hazardous both for the humans and ecosystems. For such reason, there is a growing interest to determine the occurrence of these contaminants in water environment, to estimate their inputs towards wastewater treatment plants (WWTPs), to optimize treatment conditions in order to minimize their release into the effluents, as well. The present chapter is aimed at reporting levels, removal and fate of 16 PAHs, classified as priority pollutants by EPA, in wastewater treatment plants, sludge and surface water.

Abstract
The increasing contamination of freshwater systems by anthropogenic chemicals is a growing global concern. Among the target non conventional pollutants, Polyclycic Aromatic Hydrocarbons (PAHs) constitute a major issue due to their toxic, mutagenic, carcinogenic, teratogenic and endocrine disrupting properties which make them hazardous both for the humans and ecosystems. For such reason, there is a growing interest to determine the occurrence of these contaminants in water environment, to estimate their inputs towards wastewater treatment plants (WWTPs), to optimize treatment conditions in order to minimize their release into the effluents, as well. The present chapter is aimed at reporting levels, removal and fate of 16 PAHs, classified as priority pollutants by EPA, in wastewater treatment plants, sludge and surface water.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
