수산생물의 서식처가 감소한 이유는? | 그러나, 1990년대 이후 지역 산업 및 관광 활성화를 위한 간척과 매립, 산업단지 및 관광단지의 조성, 연육교의 건설,해상케이블카 설치 등 다양한 연안 개발사업이 추진되었고,양식산업의 발달에 따른 무분별한 어업면허의 허가, 가용먹이량을 초과하는 양식시설의 설치 등 연안이용 증가로 인해 수산생물의 서식처는 감소하였다. 더욱이, 육상으로부터 유입되는 각종 유기물 및 중금속 등 오염물질 부하량이 증가하면서 적조, 빈산소수괴 발생 등 연안 재해가 빈번히 발생하고 오염물질에 의한 수산생물의 질병 발생, 성장저하, 높은 폐사율과 이를 해결하기 위한 무분별한 항생제의 사용 등으로 인해 안전하고 건강한 수산물 생산해역으로서 그 기능을 위협받고 있다. | |
해저퇴적물이 중금속의 가장 큰 저장고인 이유는? | 일반적으로, 중금속은 입자물질에 잘 흡착하는 성질이 있어 해수 중에 용존상태로 존재하기 보다는 동·식물플랑크톤에 흡수되거나 이들의 사체, 수산생물의 배설물 등 수중에 부유하는 유기물 및 입자와 결합하여 해저퇴적물에 침강하여 축적된다. 이로 인해 해저퇴적물 내 중금속 농도는 해수보다도 103~ 105 배 정도 높아 퇴적물은 해양환경에서 중금속의 가장 큰 저장고로 알려져 있다(Sin et al. | |
중금속은 무엇인가? | 중금속(As, Cd, Cr, Cu, Fe, Hg, Pb, Zn)은 쉽게 분해되지 않고 오랫동안 환경에 남아 순환하는 난분해성, 잔류성 물질로 일부 중금속의 경우 자체적으로 가지는 강한 독성으로 인해 생물에 나쁜 영향을 줄 수 있어 최근 전 세계적으로 주목 받고 있는 유해 환경오염물질 중에 하나이다(Yu et al.,2008; Billah et al. |
