Résumé :	Eggs from Sparrowhawks from Brandenburg (former GDR) and North-Rhine-Westphalia (former FRG) were examined for their burden of PCB, DDT, HCH, HCB and the heavy metals lead and cadmium. Significant differences emerged in the cases of PCB and DDT and its metabolites between the populations of the two regions. The other examined xenobiotics were detectable only in low concentrations. The DDT concentrations were distinctly higher in the samples from the former GDR, while PCB concentrations were higher in the eggs from North-Rhine-Westphalia. The results reflect clearly the different use and prohibition of the examined xenobiotics in the two former german states. In spite of the differences in the PCB burden, the PCB pattern in the eggs of the different regions is nearly identical. Eggshell indices correlate negatively with DDT burden in both sample areas.
