수서생물에 대한 Bisphenol-A의 환경위해성 평가

Abstract

Water quality management is changing toward the consideration of promoting the health of aquatic ecosystems centered on human health, because it promotes the health of aquatic ecosystems and ultimately affirms human health and society. This is because it acts as a positive influence. In this study, we conducted an environmental risk assessment for Bisphenol- A, which was recently detected in water systems. The test species are Pseudokirchneriella subcapitata, Daphnia magna and Danio rerio’s embryos, and the test method follows the OECD Test Guide. The EC50 of P. subcapitata and D. magna was 1.53 mg/L and 3.88 mg/L, respectively, and the LC50 of D. rerio’s embryo was 1.23 mg/L. Based on this, the predicted no-effect concentration (PNEC) was calculated to be 12.3 μg/L, and the harmful index (HQ) was calculated to be 0.253. But, If we applied 22.972 μg/L which is maximum detected concentration in Yeongsangang, then HQ was calculated to be 1.868, so Bisphenol -A has the potential to great harmful at aquatic organisms.
