Obesity leads to a variety of health risks, and lead, which is ranked second in Agency for Toxic Substances and Disease Registry's priority list of harmful substances, may be more harmful to individuals that are obese. C57BL/6 mice were fed a normal diet or a high‐fat diet with or without exposure to 1 g/L lead exposure in drinking water for 8 consecutive weeks. Serum and hepatic biochemistry analysis, histopathological observation, and RT‐qPCR were used to explore the potential mechanism of liver damage in obese individuals after Pb exposure, and fecal microbiota transplantation was performed to investigate the role of the gut microbiota in the progression of fatty liver disease. We found that the progression of fatty liver disease induced by high‐fat diets was accelerated by chronic lead intake. In addition, the occurrences of liver injury in recipient mice suggested the role of the gut microbiota. These findings indicated that the combination of lead and a HFD exacerbated hepatic lipotoxicity by activating LPS‐mediated inflammation, and that gut microbiota disorders and impaired intestinal barrier function play pivotal roles in the progression of fatty liver disease.

The Zaozigou gold deposit is recognized as one of the largest and most significant independent gold deposits in northwest China, representing a colossal orogenic gold-antimony deposit. It is imperative to delve into the hydrochemical characteristics and controlling factors within the mining area to unveil the groundwater circulation evolution process and enhance water resource management. In 2018, a comprehensive collection of 50 groups of groundwater samples was conducted, alongside 17 groups of surface water and underground mine water samples in 2023. Compositional descriptive analysis, correlation analysis, Piper three-plot, Gibbs map, ion ratio method, hydrogeochemical simulation and PCA methods were employed to reveal the chemical characteristics and evolution process of groundwater in the Zaozigou gold mine. Furthermore, employing water isotopes theory allowed for the identification of recharge sources and circulation conditions within the Zaozigou Gold Mine. The findings indicated a transition from HCO3-Na·Ca type polluted water in 2018 to primarily the SO4-Ca·Mg type and HCO3·SO4-Na·Ca·Mg type groundwater hydrochemistry types by 2023. The hydrochemical characteristics of the study area are closely related to the mining depth and time. The chemical characteristics are influenced by various factors such as rock weathering, mineral dissolution, cation exchange processes, atmospheric precipitation as well as human activities related to pollution from industrial mining activities.
