摘要: Abstract The estrogenicity of waters collected from an important hydrological system in Brazil (Paraiba do Sul and Guandu Rivers) was assessed using the yeast estrogen screen (YES) assay. Sampling performed rivers at outlets conventional water treatment plants (WTP). removal estrogenic activity by ozonation chlorination after (clarification sand filtration) investigated employing samples River spiked with estrogens bisphenol A (BPA). results revealed a preoccupying incidence levels higher than 1 ng L−1 along some points rivers. Another matter concern number WTPs presenting surpassing 1 ng L−1. oxidation techniques (ozonation chlorination) were effective for combination both led to good less amounts oxidants.
