説明

We established a method for the simultaneous analysis of seven preservatives and fiveantimicrobials in water. These chemicals are widely used in cosmetics, and their presence inriver water is of concern. We used the method to test 13 sites in Japanese rivers and streamscontaminated by domestic wastewater, effluent, or industrial wastewater. 2-Phenoxyethanol(2-PE), isopropylmethylphenol, resorcinol, and triclosan were detected at most sites; themaximum concentration of 2-PE detected was 14 000 ng L-1. The results suggest that themajor sources of 2-PE were cosmetics and household detergents. The ratio of methylparabento n-propylparaben in river waters with direct wastewater drainage was similar to that incommon cosmetics. This is the first research on levels of 2-PE, isopropylmethylphenol, andchlorphenesin in river water.
