AR concentrations in liver of rodents trapped in the different trapping sites. Concentrations of total (A) or individual (B) ARs are presented. AR concentrations were determined by LC-MS/MS as previously described47. Results are presented in (A) as median with a box extending from the 25th to 75th percentiles, in (B) as median with interquartile range. Sites 9 and 14 corresponded to control sites. First-generation AR = CTTL, coumatetralyl; WARF, warfarin; CHL, chlorophacinone. Second-generation AR = BROMA, bromadiolone; DFC, difenacoum; BFC, brodifacoum; FLO, flocoumafen; DFT, difethialone. The dashed line corresponds to the concentration of 1000 ng/g. RR for Rattus rattus, MM for Mus musculus and RN for Rattus norvegicus.
