| Abstract |
The present study investigated the bioaccumulation of organochlorines in two milk-producing animals (goats and cows) grazed on the same feed to explore the extent of organochlorines availability in milk and any species effect on the bioaccumulation pattern. Six organochlorine pesticides: aldrin, α-endosulfan, β-endosulfan, p,p'-DDE, o,p'-DDT and p,p'-DDT were determined in samples collected from four regions in Ethiopia. Aldrin (11.6μgkg(-1)) was detected only in one cow milk sample and α-endosulfan was detected in one goat milk sample at a level of 142.1μgkg(-1), and in one cow milk sample (47.8μgkg(-1)) from the same region. p,p'-DDE was detected in 40% of the milk samples analyzed while o,p'-DDT and p,p'-DDT were found in high amounts in almost all samples. The average total DDT (excluding DDD) in the samples was 328.5μgkg(-1). Regions known for their malaria epidemics were the most contaminated with DDT residue. The accumulation pattern in both species was not clear under natural sampling. |
