In this study, we reviewed a group of marine biotoxins, namely yessotoxins (YTXs), focusing on their causative organisms, contaminated shellfish, domestic and foreign management status, and analytical methods. Although YTXs have not yet been reported in any cases of seafood contamination in South Ko...

마우스를 이용한 시험법의 장점과 단점은? | 일본의 경우 패류 중 PSP 독소의 함량을 마우스 독성 기반으로 설정하고 있다. 마우스 검사법은 유독한 성분을 일괄적으로 정량할 수 있다는 장점이 있지만, 생물 검정법으로 오차가 크며 감도가 낮고 마우스 치사 독성의 유무만 판단할 수 있을 뿐, 실제로 각각의 독소가 얼마나 함유되어 있는지는 측정이 불가하며, 유리 지방산 등 존재하는 다른 화합물에 영향을 받을 수 있다는 단점이 있다15). 또한 동물사용에 따른 윤리적인 문제점도 지적되고 있다. | |
해양 미세조류의 역할은? | 해양 미세조류는 대표적인 1차 생산자로 동물플랑크톤 및 상위 영양단계의 생물에 먹이를 공급하는 중요한 역할을 한다. 특히 이매패류와 같은 여과섭식자는 식물플랑크톤에 크게 의존한다. | |
일차생산이 높아지면 발생하는 문제점은? | 일차생산이 높은 해역에는 좋은 어장이 형성되며 양식업과 어업에 큰 도움이 된다. 하지만 일차생산이 지나치게 높은 경우 수층의 산소를 고갈시켜서식생물을 집단 폐사 시킬 수 있으며, 이는 막대한 경제적 손실과 심각한 환경문제로 이어질 수 있다. 또한 특정 미세조류는 독성 대사물질(marine biotoxins)을 생성하며, 이는 인간의 건강과 어업에 큰 영향을 미칠 수 있다. |
