Abstract
통영 연안 양식장 주변 해역에서의 환경특성을 조사하기 위해 2013년 7월부터 12월까지 통영 주변 10개 정점에서 해수와 퇴적물 내의 pH, 용존산소(DO), 용존무기질소(DIN), 용존무기인(DIP), 화학적산소요구량(COD), 산휘발성물질(AVS)에 대해 분석하였다. 양식장 주변 해수의 수질항목들은 계절별에 따른 경향성을 나타내었으며, 퇴적물 속 COD와 AVS를 분석한 결과 수질항목과는 달리 어장으로부터의 거리에 따라 농도가 감소하는 경향을 나타내었다. 이는 본 조사지역에서 반폐쇄성 만에 위치하고 있는 어장 활동에 의해 오염된 유기퇴적물이 비교적 빠른 유속으로 인해 주변 해역으로 분산된 것으로 예측된다.
To assess environmental characteristics of the aquaculture area in Tongyeong, pH, dissolved oxygen (DO), dissolved inorganic nitrogen (DIN), dissolved inorganic phosphorous (DIP) and chemical oxygen demand (COD), and acid volatile sulfur (AVS) were measured in seawater and sediment samples collected from 10 locations of Tongyeong coastal area from July to December in 2013. The quality of the seawater may be affected by seasonal variation rather than the distance from fish farm. However, sediment was contrary to seawater; the distance from fish farm may be a main factor to affect COD and AVS in sediment than season and other parameters. It is expected that contaminated organic sediments of fishery located in semi-closed bay are rapidly dispersed into surrounding waters due to fast current.
