영산강 수계 광주천, 황룡강, 지석천, 영산강 상류 유역내에 분포된 9개 업종 76개 배출원의 원폐수 및 방류수로부터 20개 유기화학물질 tetrachloroethylene, toluene, ethylbenzene, p-xylene, m-xylene, isopropyl benzene, stylene, bromobenzene, 1,3,5-trimethylbenzene, 2-chlorotoluene 1,2,4-trimethylbenzene, p-isopropyltoluene, 4-chlorotoluene, n-butylbenzene, 1,2,4-trichlorobenzene, naphthalene, tert-butylbenzene, sec-butylbenzene, phenol, isopropyl benzene hydroperoxide를 액체-액체 추출법으로 분리하여 기체 크로마토그래피/질량 분석계(GC/MS)로 분석하였고, 포준품과 비교함으로써 밝혔다. 특히, 화학업종의 원폐수에는 검출되지 않았으나 방류수에는 폐놀과 이소프로필벤젠 하이드로퍼옥사이드가 검출되었다. 중금속 Cr, Mn, Cu, Zn, Cd, Pb, As, Al, Fe은 모든 업종의 원폐수에 대부분 함유되어 있었으며, 이중 Fe와 Al은 다른 중금속에 비행 원폐수에 다소 많이 검출되었다. Cr, Cd, Pb, As은 전기전자, 금속업종의 원폐수에서 다소 많은 양이 함유되었으며, 이러한 9개 중금속들은 폐수처리과정에서 거의 처리가 되어 방류수에는 환경 기준 이하로 검출되거나 불검출되었다.

Abstract

Twenty organic chemical substances, tetrachloroethylene, toluene, ethylbenzene, p-xylene, m-xylene, isopropyl benzene, stylene, bromobenzene, 1,3,5-trimethylbenzene, 2-chlorotoluene 1,2,4-trimethylbenzene, p-isopropyltoluene, 4-chlorotoluene, n-butylbenzene, 1,2,4-trichlorobenzene, naphthalene, tert-butylbenzene, sec-butylbenzene, phenol, isopropyl benzene hydroperoxide were isolated from untreated and treated wastewater collected at 76 companys of 9 types industry in the basin of Young San River. Their organic compounds were elucidated by Gas Chromatography/Mass Spectrometry (GC/MS) and by comparison with each standard reagents. Especially, phenol compound is detected from effluent water but not detected from plant wastewater in the chemical industry. Heavy metal, which are Cr, Mn, Cu, Zn, Cd, Pb, As, Al and Fe, are contained in the plant wastewater of all industry, Fe, Al of them is more detected than the other metals in plant wastewater. Cr, Cd, Pb, As is contained much in plant wastewater of electricity and electron, metal molding industry. Nine metals is nearely treated when plant wastewater is treated, and then the concentration of each other metals is detected below water quality standard or not detected by using AA.
