Residual biotoxicities in the secondary effluents of municipal sewage treatment plants and effects of ozonation on toxicity reduction
|
Abstract:
The agonistic activity of retinoic acid receptor(RAR)and the genotoxicity induced by the influent and effluent from 9 sewage treatment plants(STPs)in different cities were investigated,and the efficiency of ozonation for the removal of the toxicity was evaluated.Raw sewage contains relatively high RAR agonistic activity and genotoxicity.Traditional biological treatment reduces the RAR agonistic activity and genotoxicity,but all of the investigated secondary effluents were still genotoxic,while the effluents...
