Abstract : The main sources of dispersion of pharmaceutical substances in environment are wastewater treatment plants. Based on the analysis of the database built during this project, the amounts of pharmaceutical substances found in plants can be directly related to the amount consumed. Regarding their elimination from the liquid phase, the situation is very disparate. The elimination yield of hormones can be null or very large. Halogen-based X-ray contrast media (or AOX) are mainly non biodegradable. The effects of antibiotics on activated sludge have been especially investigated due to their consumption, presence in aquatic environment and specific action on bacteria. Batch tests have been performed to evaluate the toxicity of these active pharmaceutical ingredients on activated sludge. Sludge morphology was monitored by analysis of light microscopy images. Depending upon the applied dose, erythromycin and tylosin, two macrolides widely used for human and animal health care, inhibit the elimination of organic pollution and damage biomass. These antibiotics have a deleterious effect on ammonification, nitritation and nitratation
