“…Taihu Lake, where the content is up to 6 ng g -1 , Honghu Lake, up to 19.9 ng g -1 , and Baiyangdian Lake, up to 12.8 ng g -1 (Liu et al 2009;Yuan et al 2013;Hu et al 2010). However, the average content of Σ HCH in lake sediments in Poland is comparable to the content of Σ HCH in sediments of those lakes, as well as to the content of HCH in the sediments of lakes from Svalbard Island (Norway), which contain from 0.8 to 6.5 ng g -1 Σ HCH, the sediments of Lake Victoria (Uganda), which contain up to 5.48 ng g -1 γ-HCH, or the sediments of Lake Manyas (Turkey), referred to as Bird Paradise, which contain 1.08 ng g -1 α-HCH, 1.95 β-HCH and 0.46 ng g -1 γ-HCH on average (Jiao et al 2009;Erkmen et al 2013;Wasswa et al 2011). The maximum content of Σ HCH in the lake sediments is lower as compared to the content of HCH in river sediments in Poland, which contain up to 122 ng g -1 , e.g.…”

“…In the past, the channel ended in wetland areas, allowing wastewater to be drained into papyrus swamps before entering the Bay. However, in recent years the wetlands which played the role of secondary treatment have been degraded due to settlement and commercial activities (Wasswa, 2009). The water turbidity in the Bay has increased while the water transparency has declined due to excessive waste input.…”

“…These developments coupled with a population of over one million people in its catchment area have resulted in increased pollution (Banadda et al, 2009(Banadda et al, , 2011a(Banadda et al, , 2011bWasswa et al, 2010). Polychlorinated biphenyls (PCBs) have previously been documented in the lake (Ssebugere et al 2013a, b;Ssebugere et al, 2014).…”

“…This may be attributed to slow degradation or recent inputs of the pesticide in the environment. The high percentage composition of o,p'-DDT and p,p'-DDT with respect to total DDT in both wetlands clearly illustrates that DDT usage has not been eradicated yet in the country, and there might be new inputs of the pesticide to the aquatic ecosystems as asserted by (Kyarimpa, 2007;Sebugere et al, 2008;Wasswa, 2009). This situation suggests that, although it was restricted, the illegal use of DDT still continues.…”

“…Although DDT was banned for agricultural and public health purposes in Uganda in the mid 1980's, its derivatives have been detected in sediments (Wasswa, 2009), water (Kasozi et al, 2006) and fish (Bimenya et al, 2007;Kasozi et al, 2006;Kyarimpa, 2007;Ogwok et al, 2009;Sebugere et al, 2008) from various aquatic ecosystems. These derivatives are still slowly being released into aquatic and terrestrial food chains and can reach significant concentrations in animals at higher trophic levels.…”
