Occurrence and assessment of perfluorinated chemicals in wild fish from Northern Germany.

Residues of the perfluorinated chemicals perfluorooctanesulfonate (PFOS) and perfluorooctanoicacid (PFOA) were investigated in wild fish caught from different German waters including the North and the Baltic Sea, Lake Storkow in Brandenburg, several rivers in Lower Saxony, and rivers and lakes in the city of Berlin. The sample locations represent waters with no, low, medium and high portions of treated municipal sewage discharges. The investigated fish filet samples included 51 wild eels, 44 bream, 5 herring, 5 mackerel, 3 carp and 4 trout.

Occurrence of residues of the veterinary drug malachite green in eels caught downstream from municipal sewage treatment plants.

Residues of malachite green (MG), a veterinary drug illegally used for the treatment of aquacultured fish, have been found in wild eels caught from surface waters downstream from the sewers of different municipal sewage treatment plants (STPs). MG and its metabolite leucomalachite green (LMG) were detected with total concentrations up to 0.765 microg kg(-1) fresh weight in the tissues of 25 out of 45 eels caught from different lakes, a river and a canal in Berlin, Germany.
