ClearMicroplastic effects on carbon cycling processes in soils
Researchers reviewed how microplastics affect carbon cycling processes in soils, including their influence on microbial activity, plant growth, and litter decomposition. Since microplastics are themselves carbon-based materials, they can directly alter soil carbon stocks while also indirectly shifting microbial communities. The study calls for a major research effort to understand the widespread effects of microplastics on soil functioning and terrestrial ecosystem health.
