The impact of microcystin on antibiotic resistance genes and microbial communities in Yangtze River sediments.

The escalating of water pollution associated with microcystins (MCs) and antibiotic resistance genes (ARGs) poses a significant environmental challenge. As one of China's most crucial water systems, the Yangtze River's ecological health is not only vital for regional ecosystems but also carries global environmental significance. While the concentration of MCs detected in the Yangtze River sediments is moderate, the impact of exogenous MCs on ARGs and microbial communities within these sediments remains poorly understood.
