Abstract

The aim of this study is toxicity assessment using two types of sea urchins (H. pulcherrimus, M. nudus) that can representative primary consumers in potential coastal environments pollutants, Zinc undecylenate (ZU), which is used for various purposes, such as pharmaceutical agents and anti-bacterial and anti-fungi. The Fertilization rate and normal embryogenesis rate of H. pulcherrimus and M. nudus were concentration-dependent decreased. Besides, EC50 of fertilization rate with H. pulcherrimus and M. nudus were 11.27 mgl-1 and 1.48 mgl-1, and EC50 of normal embryogenesis were 0.94 mgl-1 and 3.78 mgl-1. NOEC of normal embryogenesis were 0.20 and 0.78 mgl-1, respectively. In addition, to find the safety criteria of the ZU on the marine environment. PNEC value was 0.0094 mgl-1, calculated using the toxicity values of two species of sea urchin derived from this study and the acute toxicity results of the coastal area through literature research. The above results will be used as basic data for establishing environmental protection strategies for marine environmental pollutants. 본 연구에서는 살균제, 항진균제 등의 의약품을 포함하여 다양한 목적으로 사용되며, 신방오도 료로서의 가능성이 확인된 바 있는 Zinc undecylenate (ZU)를 이용해 연안환경 내 1차 소비자를 대표할 수 있는 성게 2종(H. pulcherrimus, M. nudus)에 대한 독성평가를 실시하였다. 실험결과 ZU에 대한 H. pulcherrimus와 M. nudus의 수정률 EC50은, 각각 11.27 mgl-1과 1.48 mgl-1로 나 타났다. 또한, 정상배아 발생률의 EC50은 각각 0.94 mgl-1와 3.78 mgl-1로 나타났으며, NOEC는 0.20 mgl-1, 0.78 mgl-1를 나타내었다. 본 연구에서 도출된 성게 2종과 문헌조사를 통한 연안양 식생물 2종의 급성독성결과를 이용하여 Predicted No Effect Concentration (PNEC)를 계산하였 다. PNEC 값은 0.0094 mgl-1로 나타났으며, 위와 같은 결과는 해양환경 오염물질에 대한 환경 보호전략 수립을 위한 기초자료로 활용될 것이다.
