In this paper, acute and subacute toxicity effects of on an environmental estrogen, Bisphenol A (BPA), on zebrafish were investigated. The median lethal concentration (LC50) and the median effect concentration (EC50) of BPA to zebrafish embryos and larvae were calculated. Additionally, effects of BPA on vitellogenin (VTG) gene expression and mating ability to adult male zebrafish were investigated for subacute toxicity analysis. Differed from previous studies on toxicity of BPA, acetone, a relative low-level toxic solution, was adopted as the carrier solvent of BPA in this study. Results showed that the values of 24h、48h and 72h LC50 of BPA on zebrafish embryos and larvae were 16.667mg/l, 9.944 mg/ l, 8.222 mg/l and 20.938 mg/l, 15.170 mg/l, 10.943 mg/l, respectively. The values of 24h and 48h EC50 of BPA on zebrafish embryos were 11.111mg/l and 8.183mg/l, while the valuSubscript textes of 24h, 48h and 72h EC50 of BPA on zebrafish larvae were 14.56mg/l, 12.133mg/l and 9.658mg/l, respectively. Subacute toxicity analysis demonstrated VTG gene was induced in male zebrafish by BPA and the increasing of its expression was both time- and dose-dependent. In addition, BPA could severely inhibit the mating ability of adult male zebrafish and a positive relevance was found between the inhibition and the concentration of BPA exposed.
