Analysis of environmental endocrine disrupting activities using recombinant yeast assay in wastewater treatment plant effluents.
A battery of in vitro recombinant yeast bioassays was conducted to assess the estrogen receptor, androgen receptor, progesterone receptor and thyroid receptor ant/agonistic activities of effluents collected from Datansha wastewater treatment plant (WWTP), furthermore to evaluate the removal efficiencies of endocrine disrupting chemicals in the WWTP. The results showed that estrogenic, anti-androgenic, anti-progesteronic and anti-thyroidic activities were observed in influent. The removal efficiencies of these compounds were more than 80%, which suggested that the present wastewater treatment processes were good enough to remove most of all kinds of endocrine disruption chemicals.
