中文摘要 | Polychlorinated biphenyls (PCBs) were determined in sediments and two fish species collected from the Murchison Bay in Lake Victoria, using high resolution gas chromatography coupled to a high resolution mass spectrometer. Total PCB concentrations (Sigma(18)PCBs) varied widely with mean values ranging from 777 to 4325 pg g(-1)dry weight (dw) for sediments and 80 to 779 pg g(-1) wet weight (ww) for fish. The PCB levels in the sediments were significantly higher at the station closest to Nakivubo channel, presumably due to effluents discharged by the channel, which may contain domestically produced commercial PCB mixtures. For fish, the concentrations in Nile perch (Lates niloticus) were significantly greater than those in Nile tilapia (Oreochromis niloticus) at all study stations, possibly due to dietary differences among species. World Health Organization-toxic equivalents (WHO2005-TEQ5) for the dioxin-like PCBs were 0.04-0.64 pg g(-1), dw and 0.01-0.39 pg g(-1) ww for sediments and fish, respectively. The non-ortho PCBs exhibited the highest contribution to the Sigma(12)TEQs (>75%) compared to the mono-ortho PCBs in both fish species. The TEQs in the present study were lower than many reported worldwide in literature for fish and were within the permissible level recommended by the European Commission, implying that the fish did not pose health hazards related to PCBs to the consumers.
