Abstract

Spatial and temporal distribution of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) was explored in the Dongting Lake area. The concentrations of total PCDD/Fs ranged from 15.4 to 38.9 pg I-TEQ g−1 in surface sediments and 0.55 to 38.9 pg I-TEQ g−1 for sediment core. The vertical distributions of PCDD/Fs in the sediment core reflected the past history of using Na-PCP and the impact of the massive flood events on the distribution of PCDD/Fs to some extent. The sediment still acts as significant PCDD/F sources and they would pose a risk to sensitive species, resulting in the risk for human exposure to PCDD/F.
