Sulfamethazine degradation and corresponding antibiotic resistance genes propagation in the aquifer porous media:a sand tank experiment

摘要：

　　In this paper,aquifer porous medium and two different kind of NO3-remediation materials was used to investigate attenuation behavior of sulfamethazine and corresponding antibiotics resistance genes(sul1,sul2),using HPLC and Q-PCR method,in order to evaluate risks posed on drinking water sources.The results showed that removal rate of sulfamethazine from aquifer sand was above 90%,higher than the material with Fe0 and without Fe0(70%and 49%respectively).For both material,there was an obvious increasing trend of resistance genes in effluent water,indicating a high dissemination risk of antibiotic resistance genes,which can provide reference for pollutant remediation and water source risk control.
