TCs and TRB in activated sludge of sewage treatment plants
1. Background The release of Pharmaceuticals and personal care products (PPCPs) such as tetracyclines (TCs) into the environment poses two major potential risk to human health . First, TCs select for resistant bacteria in treated individuals themselves. Second, the presence of TCs in streams, lakes and water supplies encourages the growth of resistant bacteria in humans and wildlife. Effluent from wastewater treatment plants (WWTPs) is a major contributor to the entry of TCs into rivers, streams, and other surface waters. TCs have been detected in influent and effluent, as well as in the sludge in WWTPs. The levels of TCs in domestic wastewater and the effluent of WWTPs are 0.98 to 700 μg-L﹣1. The transport of antibiotic resistant organisms in wastewater effluents to streams has also been reported. However, little is known about the changes in fate of TRB and the levels of TCs in wastewater treatment plants in China.
