The RISMEAU project (RISques liés aux résidus de Médicaments, biocides et antibiorésistance d'origine humaine et vétérinaire sur les ressources en EAU du bassin versant de l'Arve - Risks related to residues of pharmaceuticals and biocides, and antimicrobial resistance of human and veterinary origin on the water resources of the 2083 km2 Arve catchment located in the French Alps) was implanted from 2018 to 2024 on the SIPIBEL observatory. It was devoted to the evaluation of (i) transfers of and processes related to pharmaceutical residues and biocides from both urban sludge and manure spread on fields as fertilisers, and (ii) the environmental impacts of land spreading, in particular the ecotoxicological risks and antimicrobial resistance dissemination. The methodology was based on the physico-chemical, ecotoxicological and antimicrobial resistance (AMR - assessed by molecular biology) characterisation of leachate and soil matrices samples, and focused on organic waste products application at locally representative agronomic rates. This dataset can be reused by other researchers for comparison with their own investigations on this emerging topic under different contexts and conditions, and may contribute to international reviews. The database includes in total 26,217 values, measured on 348 samples of organic waste products, soil, in situ lysimeter leachate, earthworms, plants with 3136 usual physico-chemical values, 15,469 values on pharmaceuticals and biocides concentrations, 6827 bioassay values (ecotoxicity and phytotoxicity) and 785 values of antimicrobial resistance indicators. The 348 samples have been collected from Nov. 2019 to Dec. 2022: 4 samples in 2019, 26 in 2020, 130 in 2021 and 188 in 2022. Regarding AMR, 96 assays coding for most abundant resistance genes in healthy humans, clinically relevant antibiotic resistance genes, biocide resistance genes, heavy metal genes, integrons (class I, II and III), and mobile genetic elements (transposase genes) have been carried out.
