구리이온이 해양생물의 성장에 미치는 영향은? | , 2008), 다모류, 이매패류 및 복족류 등에서 높은 생물농축이 보고되기도 한다(Bryan, 1976). 또한 어류 및 갑각류의 성장률을 저하시키며(Marr et al. 1996; Minghetti et al. 2008; Wong et al. 1999; Mcgeer et al. 2000; Sherba et al. 2000; Flik et al. 2002), 해조류의 물질대사에 영향을 미쳐 성장을 억제하기도 한다(Fernandes and Henriques, 1991; Lidon and Henriques, 1991; Lidon et al., 1993; Ouzounidou, 1994). | |
구리이온이 연체동물에게 미치는 영향은? | 구리이온와 같은 필수 미량 금속은 연체동물의 체내에 흡수되어 정상적인 생명활동의 유지와 생리적 반응의 항상성 유지에 이용되기도 하지만, 필요 이상의 농도에 노출될 경우 세포 내부의 구조적 이상을 유발하거나 생체 기능의 장애를 일으켜 생리적 활동에 부정적인 영향을 끼치게 된다(Kawai, 1959; Sutherland et al., 1981). | |
해양에 존재하는 각종 금속들이 해양생물에게 미치는 영향은? | 해양에 존재하는 각종 금속들은 직접 또는 여러 가지 변화를 거치면서 해양생물의 체내에 흡수되며(Bryan, 1976), 체내로 흡수된 금속들은 항상성의 유지, 각종 물질 대사 및 효소의 보조인자로 사용되기도 하지만(Geret and Bebianno, 2004), 고농도의 장기간의 노출은 독성을 유발하게 된다(Wang and Fisher, 1999). 일반적으로 수중에 존재하는 구리이온(Cu2+)은 노출 시간과 노출 농도에 비례하여 갑각류 및 어류 등의 사망, 성장 및 생화학적 변동에 영향을 미치며(Marr et al. |
