PESPOT : Evaluer l’occurrence de pesticides polaires et de leurs produits de transformation dans des eaux potables

The PESPOT project aims to carry out a broad mapping of pesticide residues present in drinking water,with a particular focus on persistent and polar organic molecules, using non-targeted analyticalapproaches based on high-resolution mass spectrometry (HRMS). High method sensitivity and long-termcontaminant integration were achieved through the optimization and deployment of passive samplerscombining complementary phases in terms of physicochemical properties to characterize a widecontamination profile. The identified molecules were then analyzed across continuums(resource/treatment/distribution), enabling the connection between the water source and distributedwater. This initiative aims to provide new data on water contamination to distributors, local authorities,and public decision-makers, thereby contributing to discussions on the regulatory monitoring ofphytopharmaceuticals in drinking water.
