Leibniz Institute for Zoo and Wildlife Research Reports Findings in Risk Management: Risk management

29 OCT 2021 (NewsRx) – By a Journalist-Staff News Editor at Daily Insurance News – New research on risk management is the subject of a report. According to information from Berlin, germany, by reporters at NewsRx, the research said: “The increasing use of chemicals in the European Union (EU) has resulted in environmental emissions and wildlife exhibits. To approve a chemical in the EU, producers must perform an environmental risk assessment, which is usually based on data generated under laboratory conditions without taking into account the ecological and landscape context.

Funders of this research include AG Leventis Foundation, World Wildlife Fund.

Journalists obtained a citation for researching Leibniz Institute for Zoo and Wildlife Research, “To fill this gap and add information on emerging contaminants and chemical mixtures, we analyzed 30 livers of northern white-tailed eagles (Haliaeetus albicilla) Germany with high resolution mass spectrometry coupled with liquid and gas chromatography for the identification of> 2400 contaminants. We then modeled the influence of trophic position (dN), habitat (dC) and landscape on chemical residues and examined persistent, bioaccumulative and toxic (PBT) properties using an in silico to disentangle the differences between the predicted PBT properties and the observed exposures. Despite generally low PBT scores, most of the contaminants detected were drugs, with oxfendazole and salicylamide being the most common. Chemicals Stockholm Convention such as 4,4′-DDE and PCBs were present in all samples below the toxicity thresholds. Among the PFAS, in particular the PFOS have shown high concentrations compared to other studies. In contrast, PFCA levels were low and increased with dN, indicating an increase with prey of piscivorous species. Among plant protection products, spiroxamine and simazine have been frequently detected with increasing concentrations in agricultural landscapes. The in silico model has been shown to be reliable in predicting the PBT properties of most chemicals. However, chemical exposures in apex predators are complex and are not based only on intrinsic chemical properties, but also on other factors such as ecology and landscape.

According to reporters, the research concluded: “We therefore recommend that ecological contexts, toxicities of mixtures and chemical monitoring data be more frequently taken into account in regulatory risk assessments, for example in a weight-of-risk approach. evidence, to trigger risk management measures before adverse reactions. effects in individuals or populations begin to manifest.

This research has been peer reviewed.
