Fig. 4From: Assessing the endocrine disrupting potentials and genotoxicity in environmental samples from Taiwanese riversConcentration-survival rates of Rec+ and Rec– strains exposed to river sediment extracts of Y5, E4, and A3 (left: dry-season sediment extracts (D), right: wet-season sediment extracts (W)). R50 > 1.5 indicates significant genotoxic activity (ND: no detectable bacterial inhibition, IC50,Rec+ and IC50,Rec– were greater than 100 mg Sed-equivalent mL DMSO−1)Back to article page
