We studied a simple method for the simultaneous determination of simazine, thiuram, and benchiocarb in distilled water and river-water by high-performance liquid chromatography (HPLC) with an ultraviolet detector (UV). As a result, good linearity of the calibration curve was obtained in the concentration range from 0.01 mg l^-1 to 0.5 mg l^-1. The detection limits based on S/N=3 were 1.0μg l^-1 for simazine, 4.5μg l^-1 for thiuram, and 6.5μg l^-1 for benchiocarb. Solid-phase extraction using activated carbon and elution with acetone was recommended for enriching the three pesticides. The recoveries from 200 ml of spiked river water samples at a concentration level of 2.5μg l^-1 were 88.6〜93.8%, and the relative standard deviations were 4.9〜5.3%. This analytical method could be successfully applied to the determination of three pesticides in river water.
