No abstracts are to be cited without prior reference to the author.The Baltic Sea has been exposed to severe human impacts. Apart from eutrophication and overfishing, contamination by known organic pollutants such as PAHs, PCBs and organochlorine pesticides are of major concern, even though the levels of the latter two have decreased during the past two decades. Additionally, novel scarcely known and unknown contaminants may also cause biological effects. In the EU-funded project 'Biological Effects of Environmental Pollution in marine coastal ecosystems - BEEP', we assessed to what extent Baltic cod is affected by contaminants. During a cruise in December 2001, cod were collected in the western and southern Baltic Sea, the somatic condition factor was estimated and different indicators (biomarkers) for contaminant exposure and biological effects were analysed. In addition, various PCBs and organochlorine pesticides were measured in cod liver. The results obtained demonstrate that the contaminant levels in ...
