We established a method for the simultaneous analysis of seven preservatives and five antimicrobials in water. These chemicals are widely used in cosmetics, and their presence in river water is of concern. We used the method to test 13 sites in Japanese rivers and streams contaminated by domestic wastewater, effluent, or industrial wastewater. 2-Phenoxyethanol (2-PE), isopropylmethylphenol, resorcinol, and triclosan were detected at most sites; the maximum concentration of 2-PE detected was 14000ngL-1. The results suggest that the major sources of 2-PE were cosmetics and household detergents. The ratio of methylparaben to n-propylparaben in river waters with direct wastewater drainage was similar to that in common cosmetics. This is the first research on levels of 2-PE, isopropylmethylphenol, and chlorphenesin in river water.
