AB  - The concentrations and bioaccumulation of persistent organic pollutants (POPs) 
      were determined in four fish species from Lake Koka, Ethiopia, representing 2-3 
      levels in the food chain of the lake. Dichlorodiphenyltrichloroethanes (DDTs), 
      endosulfans, polychlorinated biphenyls (PCBs) and chlorpyrifos were identified, 
      with DDTs as the most predominant pesticide, with concentration ranging from 0.05 
      to 72.53ngg(-1) wet weight (ww). All fish tissue samples collected from different 
      species of the lake contained residues of DDTs. The maximum level of DDTs was 
      found in the fattiest, African sharptooth catfish (Clarias gariepinus) sampled 
      from the lake, with a mean concentration of 15.15ngg(-1)ww. The significant 
      (P<0.05) relationship between concentrations of DDTs and delta(15)N indicates that 
      DDTs biomagnified in the food web of the lake. The 4,4'-DDE to 4,4'-DDT ratio in 
      Oreochromis niloticus (0.6) and Cyprinus carpio (0.5) were below 1, indicating 
      ongoing use of DDTs in the study area and recent exposure of these fish species.
