초록
There are many industrial factories in the central Nakdong river basin and have been occurred water pollution accidents by hazardous chemicals such as phenol, 1,4-dioxane and perchlorate. In this study, seven volatile organic compounds, VOCs(1,3-butadiene, vinyl acetate, ethyl acrylate, epichlorohydrin, styrene,hexachloroethane, 1,4-dioxane) potentially discharged into the Nakdong river were determined by purge & trap and gas chromatography-mass spectrometry(GC-MS). Method detection limit(MDL) and limit of quantitation(LOQ) were in the range 0.14~0.38 μg/L and 0.44~1.22 μg/L, respectively. Six compounds(1,3-butadiene,vinyl acetate, ethyl acrylate, epichlorohydrin, styrene, 1,4-dioxane) were detected in wastewater treatment plants(WWTPs) and wastewater discharge facilities from the Nakdong River basin. 1,4-Dioxane was most frequently observed in WWTPs and wastewater discharge facilities.
