Abstract
연안개발에 따른 유기물 오염은 유기물 오염지표종의 분포를 증가시키고, 증가된 유기물 오염지표 종이 대상해역에 장기간 우점하여 저서생태계를 교란시킨다. 하지만 아직까지 우리나라 전 해역을 대상으 로 조하대 저서생태계 유기물 오염정도를 확인한 연구가 미미한 실정이다. 이에 본 연구는 연안개발 환경 영향평가 대상사업의 조하대 저서동물 조사결과를 분석하여 유기물 오염지표종의 분포를 확인하고, 우리 나라 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 다양하였 으며, 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 오염 정도를 평가할 수 있는 지표로 사용 가능할 것으로 판단된다.
