This study illustrates the analytical results of micropollutants in Kyung-an of Pal-dang reservoir. Sampling was performed 7 times form Aug. 2000 to Oct. 2002. The analytical method used in this study enables us to detect about 300 kinds of chemicals commonly found in surface water at ppt level by GC/MS. This investigation was focused on pesticides and phthalates of micropollutants present in Kyug-an stream. Regarding analytical results, 2∼9 kinds of pesticides and 6∼7 kinds of phthalates were detected and their total concentrations were 0.2∼3.6㎍/L and 3.1∼9.1㎍/L, respectively. Pesticides (isoprothiolane, molinate and flutolanil) and phthalates(dimethyl phthalate, diisobutyl phthalate, dibuthyl phthalate and buthyl benzyl phthalate) were selected for target compounds to evaluate the removal efficiency of three treatment processes (ozone, UV, and ozone/UV process). Of applied processes, Ozone/UV process showed the highest removal efficiency for all target compounds. UV process was also reasonable for eliminating pesticides and phthalates beside dimethyl phthalate. Ozone process was effective for pesticides oxidation but not for phthalates.
