Abstract
The purpose of this study is to investigate the distributive property of organic pollutants in effluents of argo/industrial wastewater treatment plants in Jeonnam using simultaneous analysis method of 310 chemicals. The numerous organic pollutants were detected in four sampling sites and the major chemicals were pesticides, CH type chemicals such as polycyclic compounds, CHO type chemicals such as phthalates, and CHO(N) type chemical such as aromatic amines. Moreover, 17 kinds of endocrine disrupters which include diethylptbalate were detected in each sampling sites. TU (Toxic unit) indicated cytotoxicity of samples using XTT assay, it appeared highly at A point(27.2) and D point(24.4). Also, the results from the correlation between total concentration of pollutants and TU did not correspond to the results of chemical and biological analysis.
본 연구는 영산강유역 농공폐수처리장 방류수중의 유기오염물질 분포를 관찰하였다. 시료채취 지점은 영산강 유역에 존재하는 4지점의 농공단지 폐수처리장을 선정하였다. 본 연구에서 GC-Ion trap MS로 300종의 일반적인 화학물질을 ppt수준에서 검출할 수 있는 방법을 이용하여 분석하였다. 농공폐수처리방류수에서 검출된 주요 유기오염물질은 농약류, CH구조의 방향족, CHO구조의 프탈레이트류, 그리고 CHO(N) 구조의 아로메틱 아민류였다. 또한 diethylphthalate를 포함한 17종의 내분비계장애물질이 검출되었다. XTT assay를 이용한 세포독성 결과는 TV로 나타냈으며, 그들의 세포독성은 A지점에서 27.2, D지점에서 24.4로 가장 높게 나타났다. 한편 화학적 분석 결과와 생물학적 독성도와는 일치하지 않는 것으로 나타났다.
