Environmental Risk Assessment of 20 Human Use Antibiotics in Surface Water and Urban Wastewater
Published on: 2018-06-21
Antibiotic consumption has received a lot of attention in the media in the last several years due to the increasing numbers of diseases and infections becoming resistant to traditional treatments for both humans and animals. Because they are excreted unchanged via urine and/or feces into domestic sewage, and consequently discharged to receiving waters in the effluents of urban wastewater treatment plants (UWTPs). Most of antibiotics are also associated to multidrug resistance in bacteria. The absence of full environmental fate and effect data of antibiotics inhibits an effective assessment of the potential risk through environmental pathways. This study aimed to assess the risk for a series of antibiotics mostly detected in surface waters and in the influent and effluent of UWTPs. Among those 20 antibiotics, which were in question in this study, a few of antibiotics were assessed causing low hazard to algae in surface water (Erithromycin, Spiramycin and Chlortetracycline), in UWTP influent (Ampicillin) and UWTP effluent (Ofloxacin) and medium risk in UWTP effluent (Erithromycin).
