PCDD/F and other chlorinated hydrocarbons in matrices of the federal environmental specimen bank

Minimisation of PCDD/F emissions leads to a decreasing burden of the bioindicator herring gull egg in the last few years. Unfortunately, the river Elbe sediment is highly polluted with PCDD/F. The temporal burden of the sediment is fluctuating. Due to the different intake and type of feed differences of the PCDD/F burden of herring gull eggs and pigeon eggs can be explained. Constant ratios between fat related tissue data of liver and muscle are found and can be used for predictive purposes.
