| 中文摘要: |
| 土壤中的微塑料能够与重金属污染物结合形成复合污染，从而改变单一污染物的环境行为和毒性效应，对土壤生态系统造成严重危害。目前人们对微塑料和重金属的复合毒性效应及其形成原理、污染过程的了解还十分有限，本文综述了土壤环境中微塑料和重金属的复合环境行为，讨论了微塑料对重金属的吸附解吸原理和过程，梳理了土壤环境中微塑料和重金属的迁移和转化，总结了有关二者复合毒性效应的最新研究进展，最后对未来相关工作提出展望，以期为微塑料和重金属的复合毒性研究提供参考。 |
| 英文摘要: |
| Microplastics in soil can combine with heavy metals and result in complex pollution, which can alter the environmental behavior and toxic effects of single contaminants and consequently negatively affect the soil ecosystems. However, the combined toxicity of microplastics and heavy metals and their formation principles and processes have not yet been fully elucidated. This paper presents a detailed review of the combined environmental behavior of microplastics and heavy metals in soil environment, describes the principles and processes of adsorption and desorption of heavy metals by microplastics, and characterizes the migration and transformation of microplastics and heavy metals in soil. Furthermore, it summarizes the latest research progress on the combined toxic effects of microplastics and heavy metals, and finally, it presents an outlook for future studies, to provide a reference for the combined toxicity studies of microplastics and heavy metals. |
