Emerging contaminants are micropollutants found in wastewater, such as antibiotics widely applied to prevent or treat human and animal diseases, and steroid hormones used for animal fattening. Anaerobic processes are widely applied in the treatment of swine, cattle and poultry wastewater, but their performance can be diminished by the inhibition effect of antibiotics. Emerging contaminants cannot be entirely removed by conventional wastewater treatment. They accumulate in sludge and manure applied as fertilizers on the agricultural soil, resulting in localized contamination of surface and ground waters. Released in the environment, the emerging contaminants have ecotoxicological effects in aquatic and terrestrial organisms and human health: feminization of aquatic organisms, bacterial resistance, endocrine disruption, neurotoxicity and cancer. Emerging contaminants endanger the reuse of treated wastewater for irrigation of vegetable and energy crops, a regular practice among farmers trying to overcome water scarcity in arid and semiarid areas. The uptake and bioaccumulation of emerging contaminants in plants and fodders and their subsequent entry in the human food chain have been gaining attention over the last decade. This paper provides a review on the existence and the removal of antibiotics and steroid hormones in wastewater via different treatment technologies. [ABSTRACT FROM AUTHOR] |
