摘要
In order to understand the variations of antibiotic resistance genes (ARGs) in sewage treatment plants (STPs), the distribution and removal efficiencies of 4 subtypes of intracellular ARGs (sulII, ermB, tetC and blaPSE-1) and class I integron integrase gene (intI1) in a middle-scale STP in Hebei Province were detected by PCR and real-time fluorescent quantitative PCR (qPCR). 4 ARGs and intI1 were found in all water samples and 1.26-2.30 orders of magnitude of ARGs were removed by the STP. Correlation analysis showed that intI1 and water quality factors including pH, COD, and NH3-N might affect the distribution and diffusion of tetC, ermB, and blaPSE-1. The final effluent of a STP may promote the spread of ARGs in surface water system. © 2020 Peking University.
