Summar y Amberlite XAD-2 resin extracts of river and drinking water sampled each month during the period from January to December 2008 from Northwest Area of Chiba Prefecture were investigated in order to characterize and determine the organic pollutants. On the basis of GC/FID determinations of the extracts, over 90% of XAD extractable organic substances present in the river water concentrates was found to be reduced after processing in water treatment plant. Personal care products (DEET and Crotamiton) were also identified by GC/MS to be present at low concentrations, ranging from ND to 140 ng/L. The concentrations of these organic pollutants were dependent on the application periods. Although amounts of these organic pollutants in river water samples decreased remarkably after processing in the water treatment plant, it is necessary to conduct continuous bio-assays in order to evaluate the health risk effects of these personal care products and their chlorination byproducts in drinking water.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
