Impact des systèmes de traitement du lisier dans le transfert des perturbateurs endocriniens et des antibiotiques vers l'environnement naturel

Abstract : Swine manure is generally disposed on agricultural soils as a fertilizer. However, these wastes contain different compounds that may have a negative effect on living organisms. Between these compounds, it is possible to find steroid estrogens, naturally produced by animals, as well as antibiotics, used for microbial disease control. In the environment, these compounds may alter reproductive functions in animals or the selection of microbial resistant organisms in soils microflore. The objective of this study was to assess the degradation of antibiotics and endocrine disrupting compounds through different swine waste treatment facilities. For that, we have analysed steroid hormones (GC/MS) and antibiotics (LC/MS/MS) in the two different types of swine waste treatment processes used in France: the storage pit and the biological treatment by activated sludge. Simultaneously, we have determined the abundance of enterobacteria showing antibiotic resistance in these systems. Our results showed that, compared to the storage pits, the systems including biological aerobic treatment were more efficient to limit the dispersion of chemical and biological contaminants to the environment via manure spreading practices.
