title: Concentrations and profiles of polychlorinated dibenzo-p-dioxins and dibenzofurans in bank soils collected from Dongting Lake, China.
abstract: Twelve bank soil samples from the Dongting Lake area were determined to investigate the concentrations and distributions of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). The result showed the PCDD/Fs contamination was not only confined to the surface soil, but extended into the subsoil. Total I-TEQ values for all surface soils averaged 30.3 pg/g dw (ranging from 5.53 to 75.6 pg/g dw). There were some differences in the congener profiles among soil, sediment samples and technical product of sodium pentachlorophenate, which could reflect the variety of PCDD/F sources to the environment over time.
