Poisoning caused by coumarin-type anticoagulant rodenticides (ARs) stands as the predominant method for controlling rodents globally. ARs, through secondary poisoning, pose a significant threat to predators due their lethal and sublethal effects. We examined concentration of accumulated ARs in liver samples mostly road-killed steppe polecats (Mustela eversmanii) European (M. putorius) collected throughout Hungary between 2005 2021. The polecat were found mainly from Eastern Hungary, while Western Hungary. measured six residues HPLC-FLD. Our analysis revealed presence one first-generation four second-generation 53% (36) 39% (26) samples. In 17 we detected at least two AR compounds. Although did not find variance accumulation species, displayed greater prevalence maximum whereas exhibited more diverse these Brodifacoum bromadiolone most prevalent ARs; highest concentrations 0.57 mg/kg 0.33 mg/kg, respectively. was positively correlated with human population density negatively extent natural habitats both species. To best our knowledge, this is first study demonstrate rodenticide exposure globally, Central region. appears comparatively lower than many other countries, issue poisoning remains serious problem intrude into food webs. Reduced prudent usage pesticides would provide several benefits wildlife, included humans. However, advocate prioritization ecosystem services complete prohibition toxicants.
