Summary

This review examines how microplastics in soil affect microbial communities and greenhouse gas emissions, finding that microplastics can alter the abundance and activity of soil bacteria in ways that increase carbon dioxide and nitrous oxide release. The plastics change soil structure and chemistry, creating conditions that favor certain gas-producing microbes over others. These effects could worsen climate change while also disrupting soil fertility, with indirect consequences for food production.

Microplastics (MPs) are ubiquitous in soil ecosystems and significantly impact soil microorganisms and greenhouse gas (GHG) emissions. Although some reviews have summarized their impact on greenhouse gas emissions, no systematic analysis has been conducted on how soil physicochemical and microbial properties affect these emissions. Firstly, this review details that MPs alter microbial abundance, structure, activity and gene expression, directly stimulating CO and NO emissions, though their impact on CH remains inconclusive. Additionally, MPs change rhizosphere microbial growth, cause soil nutrient loss, and induce plant toxicity, indirectly affecting GHG emissions. Finally, this article suggests strengthening research on rhizosphere and MPs surface microbial communities, exploring interactions with clay and minerals, and investigating GHG emission mechanisms to understand the ecological effects of MPs.
