We investigated the concentrations of acid volatile sulfide (AVS), ignition loss (IL), total organic carbon (TOC), total nitrogen (TN), and metallic elements (As, Cd, Cr, Cu, Fe, Hg, Mn, Pb, and Zn), in August 2015, to determine the spatial distribution and pollution status of organic matter and met...

연안에 유입된 유기물과 금속원소는 어떻게 되는가? | , 2017). 연안에 유입된 유기물과 금속원소는 조류와 같은 물의 흐름에 의해 외해로 이동하기도 하지만 대부분 입자물질에 흡착된 후 연안에 침강하여 퇴적물에 축적된다(Fang and Hong, 1999; Ra et al., 2013; Hwang et al. | |
연안 퇴적물의 특성은? | 일반적으로 연안 퇴적물은 해수와 달리 멀리 이동하지 않고 그 해역에 오랫동안 존재하므로 해역의 급격한 생지화학적 환경변화를 잘 반영하고, 오염의 역사를 장기간 보존하는 특성을 가지고 있어 그 해역의 환경특성 및 오염현황을파악할 수 있는 좋은 지표로 알려져 있다(Choi et al., 1999;2015a). | |
양식 패류의 생산량 감소의 원인으로 추정되는 것은? | 0 만톤 생산되고 있다(MOF, 2017b; NIFS, 2019). 아직 그 감소 원인에 대해서는 명확하게 밝혀지지 않았지만, 일부 연구에서 육상으로부터 영양염류, 금속과 같은 환경 오염물질의 과도한 유입 뿐만아니라 장기간에 걸친 어장의 이용, 과밀양식 등으로 양식장에서 발생하는 다량의 양식부산물(배설물, 생물사체 등)로인한 양식어장 환경의 악화가 양식생물의 성장저하, 잦은질병 발생, 대량폐사 등을 유발하여 어장 생산성 및 양식생물의 품질을 저해하는 것으로 보고되고 있다(NFRDI, 2008;Kwon, 2010; Lee et al., 2011; Choi et al. |
