Geochemical data on iron

Summary

Scientists studying wetlands found that microplastics — tiny plastic particles from broken-down trash — are changing the way natural bacteria process iron in soil and water. This matters because these iron-driven processes help filter pollutants and keep wetland ecosystems healthy, so if microplastics are disrupting them, it could affect water quality in areas that supply drinking water or protect coastlines. While this study focused on environmental chemistry rather than human health directly, it adds to growing evidence that microplastic pollution can ripple through natural systems we depend on.
