[Pollution Characteristics and Risk Assessment of Antibiotics and Resistance Genes in Different Water Sources in the Wuhan Section of the Yangtze River].

The distribution characteristics, correlations, and potential ecological risks of 13 antibiotics and 10 antibiotic resistance genes (ARGs) in 16 water sources in Wuhan were analyzed using solid-phase extraction-ultra-high performance liquid chromatography-tandem mass spectrometry (SPE-UPLC-MS/MS) and real-time quantitative PCR technology. The distribution characteristics and correlations and potential ecological risks of antibiotics and resistance genes in this region were analyzed. The results showed that a total of nine antibiotics were detected in the 16 water source samples, and the concentration range was ND-177.36 ng·L-1. The concentration distribution presented as follows:Tributary Jushui River
