Résidus médicamenteux vétérinaires : quelles molécules rechercher dans les eaux superficielles en contexte d’élevage intensif ?

Abstract : The occurrence of human and veterinary pharmaceuticals in the rivers flowing through watershed draining agricultural soils is of growing concern. Veterinary drugs are particularly widespread in intensive livestock watershed. Nevertheless, in these contexts, their occurrence has not yet been extensively studied. To develop analytical methods dedicated to the analysis of those veterinary pharmaceuticals, a prioritization of the molecules of interest is necessary. Surveys have been conducted with cattle, pigs and poultry veterinarians working on two watershed. The identification of the prescribed molecules and their hierarchy has been performed thanks to an indicator of the level of global prescription and has led to a list of 60 prioritized molecules to analyze in the mixed-use watershed. Among those molecules, 27 have been effectively analyzed in the superficial water from two watershed in Brittany. The quantification of 5 veterinary drugs (sulfamethazine, flunixin, enrofloxacin, tylosine and eprinomectin) in the rivers evidenced the occurrence of pharmaceuticals from livestock origin in the mixed-use watersheds.
