: 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.

: 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 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

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 It serves as a stark reminder of the

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

: 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 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.
