title: Levels of PCDD/Fs, Dl-PCBs and HCB in air, soils and sediments from a city with multiple thermal-related industries in China.
abstract: The levels of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), dioxin-like polychlorinated biphenyls (dl-PCBs) and hexachlorobenzene (HCB) were measured in various environmental compartments in Tangshan, China, which contains multiple thermal-related industries. The total toxic equivalent concentrations of these pollutants were 138 ± 87.2 fg/m(3) in air, 3.43 ± 2.88 pg/g in soils, and 1.42 ± 1.5 pg/g in sediments. The 2,3,7,8-PCDD/Fs profiles in atmospheric samples suggest that thermal-related industries are the most likely potential sources. Of the dl-PCBs, CB-77, CB-105 and CB-118 were the most abundant congeners and CB-126 was the dominant contributor to the TEQs from the dl-PCBs.
