Abstract<\/h2>\n
\n

Antibiotic resistance genes (ARGs) have gained global attention due to their public health threat. Extracelluar ARGs (eARGs) can result in the dissemination of antibiotic resistance via free-living ARGs in natural environments, where they promote ARB transmission in drinking water distribution systems. However, eARG pollution in tap water has not been well researched. In this study, concentrations of eARGs and intracellular ARGs (iARGs) in tap water, sampled at Tianjin, China, were investigated for one year. Fourteen eARG types were found at the highest concentration of 1.3\u2009\u00d7\u2009105<\/sup>\u00a0gene copies (GC)\/L.\u00a0TetC<\/em>\u00a0was detected in 66.7% of samples, followed by\u00a0sul1, sul2<\/em>, and\u00a0qnrA<\/em>\u00a0with the same detection frequency of 41.7%. Fifteen iARGs (including\u00a0tetA, tetB, tetM, tetQ, tetX, sul1, sul2, sul3, ermB, blaTEM,<\/em>\u00a0and\u00a0qnrA)<\/em>were continuously detected in all collected tap water samples with\u00a0sul1<\/em>\u00a0and\u00a0sul2<\/em>\u00a0the most abundant. Additionally, both eARG and iARG concentrations in tap water presented a seasonal pattern with most abundant prevalence in summer. The concentration of observed intracellular sulfonamide resistance genes showed a significantly positive correlation with total nitrogen concentrations. This study suggested that eARG and iARG pollution of drinking water systems pose a potential risk to human public health.<\/p>\n
