“…The results were also in the range of data found in sediments from tropical areas in Asia: the Mekong River delta in Vietnam (Carvalho et al, 2008) and riverine and coastal waters of Surabaya in Indonesia (Ilyas et al, 2011). The levels were lower compared to concentrations reported for industrialized areas in Europe and United States of America (Covaci et al, 2005;Vane et al, 2007;Vives et al, 2007;Castells et al, 2008;Jiao et al, 2009;Martinez et al, 2010;Mohammed et al, 2011) (Table 2). The proportion of the 6 indicator PCBs (Σ 6 PCBs) to Σ 18 PCBs in this study were between 80 and 88% (with a mean value of 84%).…”

• High concentrations of PCBs were found at sites near wastewater discharges.• The PCB concentrations were low to moderate compared to other locations worldwide.• Based on the European Commission set TEQ, the fish were fit for human consumption. 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 (Σ 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 (WHO 2005 -TEQs) 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 Σ 12 TEQs (N75%) 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. a b s t r a c t a r t i c l e i n f o

In the UK, high levels organic pollutants have been observed in the Mersey, Clyde, and Tyne estuaries (Vane et al, 2007;Vane et al, 2010;Nicolaus et al, 2015).…”

“…On the other hand, bottom sediment is an important sink and reservoir of anthropogenic pollutants and has large impact on their distribution, transport, and fate in aquatic environment. Furthermore, vertical profile in dated sediment core can be used to estimate historical depositions of POPs into aquatic environments (Covaci et al 2005;Song et al 2004). In view of the above, contamination of dioxins in the sediment cores from TGD area was screened in this paper to evaluate the environmental safety.…”

In order to screen dioxin pollution in sediment of Three Gorges Dam (TGD) area, three sediment cores were obtained from two sites in 2010~2011; each core was divided into different samples with every 10 cm depth. Sediment dating determined by radiometry ( It could be concluded that the distribution of dioxins showed the spatial heterogeneous which resulted from the strong mixing and sediment deposition characteristics. Dioxin concentration in sediment cores was low with very low environmental risk potential. Dioxins at the two sites had the same origin, and exogenous input was the main source. It is the first report on the dioxins concentrations in sediment cores in the TGD area.
