| "Recently, there has been a growing public concern about the emergence of environmental pollution of water sources from Pharmaceuticals and personal care products (PPCPs). Considering the route PPCPs take to reach water environment, wastewater treatment plants (WWTPs) may facilitate their initial entry. If PPCPs are not properly treated during the wastewater treatment process, they can contaminate water environment, including drinking water sources. Considering the current level of knowledge regarding this problem, it is necessary to clarify the fates of PPCPs in WWTPs to identify appropriate treatment methods. In our research, we analyzed the presence of PPCPs in several WWTPs to clarify the concentrations and fates of PPCPs along the units of wastewater treatment. In addition, toxic effects of antibiotics on aquatic organisms were evaluated with ecotoxicity tests, and ecological risk of the antibiotics was evaluated by comparison between concentrations in water environment and ecotoxicity results." |
