Description
Summary:The increasing use of chemicals in the European Union (EU) has resulted in environmental emissions and wildlifeexposures. For approving a chemical within the EU, producers need to conduct an environmental risk assessment,which typically relies on data generated under laboratory conditions without considering the ecological andlandscape context. To address this gap and add information on emerging contaminants and chemical mixtures,we analysed 30 livers of white-tailed sea eagles (Haliaeetus albicilla) from northern Germany with highresolution-mass spectrometry coupled to liquid and gas chromatography for the identification of >2400 con-taminants. We then modelled the influence of trophic position (δ15N), habitat (δ13C) and landscape on chemicalresidues and screened for persistent, bioaccumulative and toxic (PBT) properties using an in silico model tounravel mismatches between predicted PBT properties and observed exposures. Despite having generally lowPBT scores, most detected contaminants were medicinal ...
