Polychlorinated dibenzo-p-dioxins/furans and polychlorinated biphenyls in fresh fishes from Qiantangjiang River, China

Muscles of two species of fish collected in Qiangtangjiang River were analyzed for polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) by high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS). Average concentrations of total PCDD/Fs in Crucian carp and White Amur bream were 1.14–7.88 pg g−1 ww and 1.02–8.18 pg g−1 ww respectively. Corresponding values for PCBs were 469.36–10 972 pg g−1 ww and 364.79–4948.0 pg g−1 ww. Average total WHO-TEQ of Crucian carp and White Amur bream from five areas ranged from 0.25 to 2.33 pg g−1 ww and 0.30 to 1.70 pg g−1 ww. The contamination level was compared with other studies and risk assessment was discussed.
