Present in the excrement of humans and animals, 17β-estradiol (E2) has been detected in the aquatic environment in a range from several nanograms to several hundred nanograms per liter. In this study, the sensitivities of rare minnows during different life stages to E2 at environmentally relevant (5, 25, and 100 ng l−1) and high (1000 ng l−1) concentrations were compared using vitellogenin (VTG) and gonad development as biomarkers under semistatic conditions. After 21 days of exposure, VTG… CONTINUE READING
