This study was conducted to find out the changes of survival, respiration and organ structure of Tegillarca granosa exposed to copper (Cu). Experimental period was four weeks. Experimental groups were composed of one control condition and three copper exposure conditions (0.125, 0.250 and 0.500 mg/L...

구리가 생물에게 미치는 영향은? | 구리는 생물체의 정상적인 대사기능에 필요한 필수 미량금속이지만 생물이 필요이상의 농도에 노출될 경우 세포의 구조 및 기능적 이상을 유발하거나 생체기능의 장애를 일으켜 생리적 활동에 부정적인 영향을 미치기도 한다 (Sutherland and Major, 1981). 최근 들어 구리는 양식용 어망 등의 부착생물 억제를 위한 도료의 성분으로 사용되거나 항균활성을 위한 재료로 사용되고 있다 (Park et al. | |
구리가 양식용 어망 등에 사용되는 이유는? | 구리는 생물체의 정상적인 대사기능에 필요한 필수 미량금속이지만 생물이 필요이상의 농도에 노출될 경우 세포의 구조 및 기능적 이상을 유발하거나 생체기능의 장애를 일으켜 생리적 활동에 부정적인 영향을 미치기도 한다 (Sutherland and Major, 1981). 최근 들어 구리는 양식용 어망 등의 부착생물 억제를 위한 도료의 성분으로 사용되거나 항균활성을 위한 재료로 사용되고 있다 (Park et al., 2003; Xiuling et al. | |
생물이 받는 위해도를 평가하는 4단계에 따를 때 중요한 것은? | 환경요인들의 영향으로 인해 생물이 받는 위해도를 평가하는 방법은 위험성 확인 (hazard identification), 노출평가 (exposure assessment), 용량-반응 평가 (dose-response assessment) 및 위해도 결정 (risk characterization) 의 주요 4단계이다 (NRC, 1983). 위와 같은 방법에 따라 위해도를 평가하기 위해서는 지표생물 (indicator organism) 과 생물지표 (biomarker) 의 선정이 중요하다 (Huggett et al., 1992). |
