Biodegradation of Microplastics in Soil
AI summary Read the abstract
This review examines how soil microorganisms, plants, and soil animals contribute to the biodegradation of microplastics, summarizing current methods and their influencing factors as more sustainable alternatives to conventional plastic waste management.
Recently, microplastic pollution has become an environmental issue with widespread concern. As a bigger reservoir of microplastics than the ocean, microplastic pollution borne by soil has an impact on its structure and properties that cannot be ignored. Furthermore, with the help of plants, soil animals and microorganisms, this emerging pollutant will eventually threaten human health. Microplastics are difficult to recycle due to their small particle size, making it hard for traditional methods of plastic pollution management to work. In contrast, biodegradation methods are gaining attention because of its environmental sustainability and wide treatment range. This paper reviews the most popular microplastic biodegradation methods and their influencing factors, aiming to provide ideas and references for the biodegradation of microplastics.

Interaction effects and mechanisms of microorganisms and microplastics in soil environment
AI summary Read the abstract
This review examines how microplastics and soil microorganisms interact: microplastics disrupt soil structure, reduce water retention, and impede plant root growth, while certain bacteria and fungi can colonize and partially degrade plastic particles through a multi-step process involving colonization, fragmentation, assimilation, and mineralization. Different polymer types (PE, PP, PS, PVC, PET) attract different microbial communities, and factors like temperature, moisture, and plastic additives affect degradation rates. Understanding these interactions is key to assessing long-term soil health impacts and developing microbial strategies to reduce plastic accumulation in agricultural soils.
