초록

본 연구에서는 벤즈이소시아졸리논의 초기 생태위해성을 평가하기 위해 물리 화학적 특성과 환경거동 및 경로를 조사하였고, 어류, 물벼룩 및 조류를 이용한 수생태 독성시험을 수행하였다. 조사 결과, 벤즈이소시아졸리논은 비휘발성으로 환경 중 주로 토양과 물에 분포하는 특성이 있으며, 토양 내 이동성과 생물농축 가능성이 낮은 편으로 나타났다. Oryzias laties를 이용한 급성 독성시험 결과 96시간-$LC_{50}$ 값은 4.7 mg/L(측정농도), Daphnia magna를 이용한 48시간-$EC_{50}$ 값은 3.3 mg/L(측정농도)이었다. Pseudokirchneriella subcapitata를 이용한 72시간-$EC_{50}$ 값은 0.456 mg/L(평균 성장률, 설정농도)와 0.262 mg/L(수율, 설정농도)이었다. 시험 종 가운데 독성에 가장 민감한 조류의 수율 $EC_{50}$ 값에 평가 계수 100을 적용한 예측무영향 농도는 2.62 ${\mu}g/L$이었다. 각 시험군의 독성 종말점을 GHS (Globally Harmonized System) 기준에 따라 분류한 결과 조류 독성은 급성독성 1등급, 어류 및 물벼룩 독성은 급성독성 2등급에 해당되었다. 본 결과를 토대로 볼 때 벤즈이소시아졸리논은 생태 환경에 대한 위해성이 예측된다.

In this study, physico-chemical properties and environmental fate were investigated and ecotoxicity tests using fish, daphnia and algae were conducted for an initial ecological risk assessment of 1,2-Benzisothiazol-3-one. Due to low volatility of the test substance under environmental conditions, it is likely to distributed in soil and water environment. The compound has low adsorption in the soil, with low bioconcentration potential. Acute toxicity results showed that 96 h-$LC_{50}$ for Oryzias laties was 4.7 mg/L (measured) and 48h-$EC_{50}$ for Daphnia magna was 3.3 mg/L (measured). In a growth inhibition test with Pseudokirchneriella subcapitata, 72 h-$EC_{50}$ was 0.456 mg/L (growth rate, nominal) and 0.262 mg/L (yield, nominal). Using the acute toxicity value of algae, predicted no-effect concentration (PNEC) in the aquatic environment was determined to be 2.62 ${\mu}g/L$ using an factor of 100. According to globally harmonized system (GHS), the compound was categorized as aquatic acute 1 for algae, while it was categorized as aquatic acute 2 for fish and daphnia. This screening assessment suggests that the test substance may pose ecological risks in the aquatic environment.
