This study highlights the growing threat of heavy metal pollution in urban green spaces, which poses risks to soil health and ecosystem stability. As cities rapidly expand, increased pollution in green areas can disrupt microbial communities crucial for soil function. Our research shows that heavy metal contamination is increasingly affecting arbuscular mycorrhizal fungi vital for plant growth and soil quality. This shift in fungal communities is driven by rising pollution levels, with significant impacts on urban ecosystems. Understanding how these pollution-driven changes shape microbial communities is crucial for managing urban soil health. These insights are especially timely, as urbanization accelerates worldwide, presenting new challenges for environmental protection. The findings are relevant for urban planning, offering strategies to mitigate the effects of pollution and maintain ecosystem functions in green spaces. This research contributes to the broader goal of preserving sustainable urban environments in the face of escalating environmental stress.
