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 δ(15)N, which indicates that DDTs could biomagnified in the food web of the lake. Generally, high… CONTINUE READING
