Abstract
In this study, the authors investigated the change of marine environment by dumping dredged materials generated by construction of Busan New Port. There are lots of possibilities to impact an ocean ecosystem by toxic materials in the dredged material dumped in the open seas. As a result of analysis of environmental monitoring in the study areas 12 times a year, COD is II grade, T-N is I grade, T-P is between II and III grade. This result is same as another results of offshore in Korea. It seems unclear that it results from the change of water quality by dumping dredged material. However, according to the result of this investigation, it is not effected extensively to the marine environment by dumping dredged materials. We need further environmental monitoring in the interest sea areas, also need to keep on investigating the impact on the marine ecosystem by dumping dredged materials.
본 연구에서는 부산신항만 축조공사 중에 발생한 준설토의 외해투기 시 투기 해역의 수질환경 변화를 조사하였다. 준설토 중에는 독성 미량금속이 포함되어 있어서 준설토의 해양투기시 해양생태계에 영향을 미칠 가능성이 있다. 이러한 이유로 준설토의 외해투기 시에는 지속적인 해양환경 모니터링이 필요하다. 총 12 회에 걸친 조사대상 해역의 환경 모니터링 분석결과를 살펴보면 수질등급으로 COD가 II등급을, T-N이 I등급, T-P가
