| Abstract: |
| Microplastics in soil can affect plant growth in a variety of ways, accumulate in plants, and eventually enter the human body via the food chain. Clarifying the mechanisms and main factors whereby microplastics influence plant growth can contribute to a systematic understanding of their environmental behavior in soil-plant systems. Both the occurrence state and physicochemical characteristics of microplastics can influence their effects on plants. In this paper, from the perspectives of particle size, shape, concentration, and type, plastic additives, and aging degree of microplastics, we review the main factors and mechanisms underlying the effects of soil microplastics on plant growth. The key direction of future research is proposed, which will provide a reference for further clarifying the impact of microplastics on soil ecosystems. |
