Abstract

The use of antifouling(AF) paints is the effective method for the protection of underwater structures from the development of marine fouling organisms. The ban on harmful substances in antifouling paints requires the development of new antifouling strategies although Tributyitin (TBT) compound had been used extensively as an active ingredient Alternatives should be as effective as conventional paints but have lower toxicity. In the present study, a TBT-free self-polishing (Cu SPC) AF paint containing $Cu_2O$, a Cu free SPC AF paint, and a Foul-release silicone AF paint, which were commercially available, were examined to investigate environmental erects of leakage waters employing Sebastes shlegeli and Artemia. Survival rates were inversely proportional to the concentration of leakage waters from AF paints and the acute toxicity of SPC AF paints was relatively higher than that of foul release AF paints.

해양구조물 수중부의 해양생물 부착을 방지하는 효과적인 방법으로 방오도료를 사용하고 있다. 트리부틸틴(Tributyltin, TBT) 화합물은 우수한 방오성능을 가져 지금까지 광범위하게 사용해 되어 왔으나, 유해물질 사용금지에 따라 새로운 기술을 적용한 방오도료 개발이 진행되고 있다. 신규 방오도료는 낮은 독성을 가지면서도 우수한 방오성능을 가져야 한다. 본 논문에서는 상용 TBT-free 방오도료 3종(아산화동 함유 자기마모형 도료(Cu SPC AF), 아산화동을 함유하지 않는 자기마모형 도료(Cu-Free SPC AF), Foul-release 실리콘 도료(Foul release AF)의 용출수가 가지는 환경영향성을 조피볼락과 알테미아를 사용하여 평가하였다. 용출수에 대한 급성독성을 조사한 결과 방오도료 용출수의 농도와 생물종의 생존율은 반비례하는 경향을 나타내었으며, 자가마모형 도료가 Foul-release 실리콘 도료보다 상대적으로 높은 급성독성을 가지는 것을 확인할 수 있었다.
