The research, led by and colleagues from the Technical University of Denmark (DTU) , investigates the presence of pesticide residues in European hares living within agricultural landscapes in Denmark. This species is often used as a bioindicator for the health of agricultural ecosystems. Key Findings
: The use of Q-Orbitrap-MS allowed for high-resolution detection of co-formulants like Bis(2-Ethylhexyl) Adipate , providing a more comprehensive look at environmental exposure than traditional testing. 126597
: It highlights that hares are consistently exposed to various chemical "co-formulants" and active pesticide ingredients, even outside of peak spraying seasons, due to their diet and habitat. The research, led by and colleagues from the
: A significant aspect of the research is the detection of multiple residues simultaneously, pointing toward the "cocktail effect" where various chemicals may interact in ways that increase toxicity. Scientific Contribution : It highlights that hares are consistently exposed
: By quantifying these levels in the European hare—a species that has seen population declines across Europe—the study provides critical data for environmental policy and wildlife management. Conclusion
: The study utilized advanced analytical techniques, including Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) , to identify a broad range of pesticides and their metabolites in hare tissues.
This study is a vital addition to environmental toxicology, reinforcing the need for stricter monitoring of not just active pesticide ingredients, but also the "inert" co-formulants that persist in wildlife. It serves as a stark reminder of the chemical footprint left by modern intensive agriculture on non-target species. Elena Hakme - Welcome to DTU Research Database
