Abstract

Various adverse effects can occur due to direct exposure from toxic substances when toxic materials are used to restore river ecosystems. Thus, this study performed analysis on the development of toxicity in terms of survival and abnormality rates using embryos of Bombina orientalis living in Korea to analyze the toxicity of materials used in the river projects. The results showed that the toxicity in cement (C group) was the strongest whereas the toxicity in plant-based polyurethane (P1 group) was the weakest. Survival rates of B. orientalis embryos were 100%, 94 - 95%, 66 - 89% and 0% in control, P1, polyurethane (P2) and C groups, respectively. Abnormalities of embryos were 10.5%, 5.3 - 10.5%, 26.3 - 27.8% and 35.7% in control, P1, P2 and C groups, respectively. Furthermore, we verified that having a sufficient curing time reduced toxic substances that were extracted. The above result suggest that cement and polyurethane hamper the early development of amphibians. In conclusion, it is highly important to review biological safety with respect to the selection of materials used to restore rivers. This study shows the importance of the selection of eco-friendly materials and processes.

독성 소재를 활용하여 하천생태복원 사업을 추진할 경우, 수생 생물이 직접적으로 독성물질에 노출되어 다양한 생물학적 문제를 야기할 수 있다. 따라서, 본 연구에서는 하천사업에 활용되는 콘크리트 소재의 독성을 분석하기 위해 한국산 무당개구리(Bombina orientalis)배아를 이용하여 생존율과 기형발생률 측면에서 발생독성 분석을 수행하였다. 콘크리트 바인더들의 독성을 평가한 결과, 무당개구리 배아의 생존율은 대조군 (control), 식물성 폴리우레탄(P1), 우레탄(P2), 시멘트(C) 실험군에서 각각 100%, 94-95%, 66-89%, 0%로 나타났다. 기형발생률은 대조군, P1, P2, C 실험군에서 각각 10.5%, 5.3-10.5%, 26.3-27.8%, 35.7%로 나타났다. 시멘트의 독성이 가장 강하게 나타났으며, 상대적으로 식물성 폴리우레탄의 독성이 가장 약한 것으로 나타났다. 또한, 충분한 양생시간을 가짐으로써 용출되는 독성물질이 저감되는 것을 확인하였다. 이상의 결과들로서 시멘트와 폴리우레탄은 양서류의 초기발생을 저해하는 것이 확인되었다. 본 연구는 하천복원을 위한 소재의 선택에 있어 생물학적 안전성을 검토하는 것이 매우 중요하며, 친환경 소재 및 친환경 공정 선택의 중요성을 보여준다.
