국내 주상용 Anti-Fouling System 처리 활성물질이 둥근성게 (Mesocentrotus nudus)의 배아에 미치는 영향

In this study, we aimed to assess the toxicity of biocide present in antifouling paint on embryos of sea urchin, Mesocentrotus nudus. Three types of biocide (Sea-nine 211, Diuron, and Irgarol 1051) were selected for the exposure experiment. The EC50 of Seanine, Diuron, and Irgarol on the fertilization rate of sea urchin were 32.8 μg L-1, 7,975 μg L-1 and 6,995 μg L-1, respectively. The EC50 of Sea-nine, Diuron, and Irgarol on the development rate of sea urchin were 31.6 μg L-1, 3,044 μg L-1, and 2,267 μg L-1, respectively. The highest toxicity was observed in the presence of Sea-nine.
