Abstract

In this study, we try to Quantitatively assess the micropollutants in Gwangyang bay, Gamag bay and Yeoa bay, using simultaneous analytical method fir 310 chemicals. In the results, several dozen organic pollutants were detected in sampling sites, and the major chemicals detected were CH type chemicals, such as aliphatic and polycyclic compounds, and CHN(O) type chemicals, such as aromatic ammines and nitro compounds. The concentration of organic pollutants was higher in summer than in winter. However, there was no association of species of organic pollutants with season. The total concentration of pesticides at each sampling site was measured within the range of $ND{\sim}9.11{\mu}g/L$. Insecticides and fungicides of pesticide type were detected in Gwangyang bay and Gamag bay, while six kinds of endocrine disrupter were detected in southern coastal waters. From the results of this study, we should estimated that the insecticides, the fungicides, and a few of the endocrine disrupters are major pollutant factors in southern coastal waters.

본 연구는 310종 다성분 동시분석 법을 활용하여 남해 연안 해역 중 광양만, 여자만, 가막만에서의 미량유기오염물질에 의한 오염특성을 규명하고자 하였다. 채수지점에서 검출된 주요 미량유기오염물질은 aliphatic, polycyclic compounds 와 같은 CH기의 화학물질과 aromatic ammines, nitro compounds와 같은 CHN(O)기의 화학적 구조를 갖는 물질이었다. 미량유기오염물질의 농도는 겨울철보다는 여름철에 높게 나타났으나 검출된 물질 종수와 계절적 상관성은 뚜렷하게 나타나지 않았다. 남해 연안 해역에서 검출된 농약의 총량은 $ND{\sim}9.11$ 이었으며 광양만과 가막만에서 살충제와 제초제의 검출이 집중적으로 관찰되었다. 또한 남해 연안 해역에서 환경호르몬성 물질은 총 6종이 검출되었다. 이러한 결과로부터 남해연안해역의 주요오염인자는 살충제와 제초제, 그리고 수종의 환경호르몬성 물질로 판단된다.
