dc.description.abstractThe 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 products with oxfendazole and salicylamide being mostfrequent. Chemicals of the Stockholm Convention such as 4,4â€2-DDE and PCBs were present in all samples belowtoxicity thresholds. Among PFAS, especially PFOS showed elevated concentrations compared to other studies. Incontrast, PFCA levels were low and increased with δ15N, which indicated an increase with preying on piscivorousspecies. Among plant protection products, spiroxamine and simazine were frequently detected with increasingconcentrations in agricultural landscapes. The in silico model has proven to be reliable for predicting PBTproperties for most chemicals. However, chemical exposures in apex predators are complex and do not solely relyon intrinsic chemical properties but also on other factors such as ecology and landscape. We therefore recom-mend that ecological contexts, mixture toxicities, and chemical monitoring data should be more frequentlyconsidered in regulatory risk assessments, e.g. in a weight of evidence approach, to trigger risk managementmeasures before adverse effects in individuals or populations start to manifest. © 2021 The Authorsen
