| Abstract: | Summary Clark, R. A. 1979. DDT contamination of the Sacred Ibis. Ostrich 50:134-138. Samples of fat and brain from Sacred Ibises Threskiornis aethiopicus in Pretoria, Transvaal, were analyzed for organochlorine insecticides. Except for traces of p,p'-DDT only p,p'-DDE was found to occur (means of 28,35 mg/kg wet fat and 0,22 mg/kg wet brain). There was a significant correlation between the concentrations of DDE in the fat and brain of birds (r = 0,53; p ? 0,01). In the period when Sacred Ibises mobilized their fat reserves there was no significant correlation between the level of body fat and the concentration of DDE in either the brain or the remaining body fat. |
