“…In aquatic ecosystems, small amounts of PCBs and HCHs may be re-dissolved at the water-sediment interface, but mostly tend to partition into sediments and suspended particles (Horzempa and Ditoro, 1983;Eisenreich et al, 1989). The chemicals have the potential to bioaccumulate across the food chain, building up in top predators through consumption of contaminated biota (Bjermo et al, 2013;Frouin et al, 2013).…”

• High concentrations of PCBs were found at locations near Jinja Municipality.• The PCB and HCH levels were low to moderate compared to other locations worldwide.• The fish from the Napoleon Gulf was fit for consumption in regard to PCBs and HCHs.• The ratios of α-/γ-HCH were low suggesting past input of lindane. a b s t r a c t a r t i c l e i n f o Polychlorinated biphenyls (PCBs) and hexachlorocyclohexanes (HCHs) were analyzed in surface sediments (b30 cm depth) and two fish species: Nile perch (Lates niloticus) and Nile tilapia (Oreochromis niloticus). The samples were collected from the Napoleon Gulf on the northern shore of Lake Victoria. The analysis was done using a gas chromatograph (GC) coupled to a high resolution mass spectrometer for PCBs and a GC equipped with an electron capture detector for HCHs. Total (Σ) PCBs in the muscles of fish varied widely with mean values ranging from 41 to 670 pg g −1 lipid weight (lw). The PCB levels in L. niloticus were significantly greater than those in O. niloticus. The large variability observed in the data was attributed to differences in feeding habits and trophic levels. While O. niloticus is a filter-eating fish species feeding mainly on phytoplankton and zooplankton, L. niloticus have predatory feeding behaviors and prefer a diet of live fish and, therefore, are more prone to bioaccumulate contaminants. The mean PCB concentrations in the sediments varied from 362 to 848 pg g −1 dry weight. Variations in PCB levels were observed from one study site to another, this was attributed to the nature and particle size of the sediments. HCH isomers were detected in fish at mean concentrations of up to 45,900 pg g −1 lw. The PCB and HCH concentrations were lower than those from previous studies elsewhere in literature and were below the maximum residue limits set by the European Commission and FAO/WHO Codex Alimentarius Commission, implying that the fish was fit for human consumption.

“…Sediment deposition continues over time, making sediment core a geochronometer to record historical variations in contaminant occurrence and to reflect anthropogenic activity in watersheds (Eisenreich et al, 1989). Since the beginning of large-scale use of synthetic pesticides in the 1950s, several generations of insecticides have been developed with the ban or phase out of older generations (Denholm et al, 2002).…”

“…Sediment cores may provide a useful tool for reconstructing a historical record of pesticide input into freshwater ecosystems and help to elucidate the temporal impacts of human activities on pesticide pollution (Eisenreich et al, 1989;Sabatier et al, 2014). Previous studies using cores have generally focused on OCPs (mainly DDTs and HCHs) and have noted a generally decreasing trend over time except for fresh input of DDTs in some areas such as Quanzhou Bay in South China and Gwangyang bay in South Korea (Gong et al, 2007;Kim et al, 2008;Wang et al, 2013;Cheng et al, 2014).…”
