We evaluated the field application feasibility that biologically derived substances (Naphthoquinone derivate: NQ 2-0) can be used for the eco-friendly mitigation of natural harmful cyanobacterial blooms in freshwater. We conducted a 30 ton scale mesocosm experiment to investigate the effects of NQ 2...

수 생태계 연구에 유용한 도구인 mesocosm 실험의 특징은 무엇인가? | 수 생태계 연구에 유용한 도구로서 다양한 분야에 이용되는 mesocosm 실험은 실제 현장에서 자연 생태계 시스템의 기능과 구조를 단순화 시킨 생태계 실험의 방법이다. 더구나 현장수를 이용한 mesocosm 실험은 화학적인 교란 혹은 새로운 환경조건(수온 상승, CO2 농도 증가, 새로운 화학물질등)이 수 생태계에 작용되었을 때 생태계 반응을 평가하기 좋은 방법이며(Ahn et al. 2001, Naito et al. 2003, Orihel et al. 2006) 더구나, 유해 조류가 발생한 현장수를 이용한 mesocosm 실험은 실험실에서 확인된 살조 물질의 효과를 현장 유사 생태계 내에서 검증하고, 적용 시 발생할 수 있는 살조효과 및 독성에 의한 생태계 교란에 대한 요인들을 현장 적용 이전에 미리 확인할 수 있기 때문에 (Odum and Odum 2003, Willis et al. 2004) 실험실 내 연구결과와 실제 현장적용 사이의 차이를 줄일 수 있는 중요한 실험이다(Han et al. 1995, Wirth et al. | |
유해 남조류에 의한 하천 오염의 특징은 무엇인가? | 특히, Microcystis sp. 종과 같은 유해 남조류는 미관상의 불쾌감, 음용수의 이취미 발생으로 인한 먹는물 확보에 어려움을 줄뿐만 아니라, 간독소 microcystins을 생성하여 야생 동물과 가축에 치명적인 해를 주며, 인간의 건강까지 위협한다(Kiviranta et al. 1991, Oberholster 2004, Kang et al. | |
남조류에 의한 녹조 대발생의 문제점은 무엇인가? | 여름철 남조류에 의한 녹조 대발생은 상수원 수원지를 포함한 하천 생태계 훼손 및 정수 비용 증가 등의 피해가 발생할 뿐만 아니라 경제적, 공중보건 측면에서 심각한 문제를 야기시킨다. 특히, Microcystis sp. |
