Abstract

Organic pollution due to coastal development increases the distribution of organic pollution indicators (OPI) and disturbs benthic ecosystems by increasing the number of organic pollution indicators dominant in the target area. However, there is a little researches on the organic pollution levels of benthic ecosystems in subtidal target coast of all over Korea. Therefore, this study analyzed the distribution of macrobenthos in subtidal around the coast development sites of EIA, confirmed the distribution of OPI, and produced the benthic health index-map (organic pollution level) of all coasts of Korea. The benthic health index of the sites was calculated using the density of each OPI, and the image program was used for the benthic health index-map. Organic pollution levels varied by projects for EIA and OPI. Lumbrineris sp. was found to be dominant throughout the coast and correlated with the benthic health index in Korea. Through this study, we will be able to confirm the future organic pollution level in the subtidal ecosystems of the project for EIA through the results of research to macrobenthos in subtidal for EIA. In addition, the distribution of Lumbrineris sp. OPI can be used as an indicator to indirectly evaluate the organic pollution level of the development site.

연안개발에 따른 유기물 오염은 유기물 오염지표종의 분포를 증가시키고, 증가된 유기물 오염지표종이 대상해역에 장기간 우점하여 저서생태계를 교란시킨다. 하지만 아직까지 우리나라 전 해역을 대상으로 조하대 저서생태계 유기물 오염정도를 확인한 연구가 미미한 실정이다. 이에 본 연구는 연안개발 환경영향평가 대상사업의 조하대 저서동물 조사결과를 분석하여 유기물 오염지표종의 분포를 확인하고, 우리나라 전 해역 조하대 유기물 오염정도를 간접적으로 확인하였다. 유기물 오염지표종별 분포 현황을 이미지 프로그램을 통해 지도로 작성하고, 전체 출현분포 현황을 통해 전 연안의 저서건강도지수(BHI, Benthic Health Index)를 도식화하였다. 유기물 오염정도는 사업구분 및 유기물 오염지표종별 분포가 다양하였으며, 유기물 오염지표종 중 Lumbrineris sp.가 전 해역에 가장 우점한 것으로 확인되었고, 전체 조하대 유기물 오염정도와 상관관계가 있는 것으로 확인되었다. 앞으로의 조하대 저서생태계 유기물 오염정도는 유기물 오염지표종 분포를 통해 확인하고, 향후 연안개발 계획 수립 시 참고자료로 활용할 수 있을 것으로 기대한다. 또한, 유기물 오염지표종 중 Lumbrineris sp.의 분포는 간접적으로 개발 대상지의 유기물 오염정도를 평가할 수 있는 지표로 사용 가능할 것으로 판단된다.
