چکیده انگلیسی
Sediments at 16 sites and muscles of four aquatic species collected in Taihu Lake were analyzed for polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) by HRGC/HRMS. The concentrations of total PCDD/Fs, PCBs and WHO-TEQ were 120.1-1315.1 pg/g dw, 889.7-29747.8 pg/g dw, and 0.83-17.72 pg TEQ/g dw, respectively in sediments; and those in muscles were 5.49-35.84 pg/g ww, 1517.10-27647.98 pg/g ww, and 0.52-3.83 pg TEQ/g ww respectively. The concentrations of PCDD/Fs and PCBs in the sediments were decreasing gradually along the water flow. The pollution levels were compared with other studies and the possible sources were discussed.
