摘要
The levels and bioaccumulation of organochlorine pesticides (OCPs) and heavy metals were studied in muscle and liver of three fish species, with two trophic levels, from Lake Awassa, Ethiopia. DDTs were the predominant organic pollutant in all species with a maximum level of 73.28 ng g(-1) wet weight (ww). p,p'-DDE was the predominate congener and showed a significant (p <0.001) relationship with delta N-15, which indicates that DDTs could biomagnified in the food web of the lake. Generally, high levels of heavy metals (Cd, Co, Cr, Cu, Ni, Pb, Zn and Hg) were found in liver samples as compared to muscles. The levels of Cd, Co, Cu, Ni, and Pb in liver samples showed negative correlation with delta N-15. They were found markedly higher in the lower trophic level fish species (p < 0.05) that indicates biodilution whereas; Zn level showed positive correlation with delta N-15. (C) 2013 Elsevier Ltd.
