In this research, the actual condition of the contaminations of 15 kinds of the pharmaceuticals and personal care products (PPCP) were determined in rural river in Japan. PPCP is the emerging contaminants for the aquatic ecosystem and human health. The research results show that the PPCP concentrations were similar or higher than in urban rivers in Japan, where the coverage of the domestic wastewater treatment plant (rural sewerage) was low. The results also indicates that the rural sewerage is a quite effective infrastructure to the depression of the PPCP concentrations in rural rivers in Japan.
