| 中文摘要: |
| 随着地膜在现代化农业中的广泛应用，微塑料在土壤中的残留问题日益严重。环境中释放的微塑料可能会与先前存在的重金属相互作用，导致生物效应(生物积累/毒性)，并对人类健康和农产品安全构成威胁。目前，大多数文章的研究集中于单一影响因素在土壤系统中的暴露和转化分析，有关微塑料和共存金属对环境联合影响的相当有限。本文综述了微塑料与重金属来源、相互作用机理与影响因素的研究现状，阐述了陆生植物对二者联合污染的生理响应。此外，未来的研究还应重点探讨微塑料与重金属共同在植物上暴露的具体分子机制，通过食物链对人类健康的影响，与其他混合污染物联合作用及微塑料老化过程对重金属迁移动态变化过程的影响。 |
| 英文摘要: |
| With the plastic films widely used in modernization agriculture, the microplastic remain in soil is becoming increasingly serious. The released microplastic can potentially interact with pre-existing heavy metals, leading to biological effects (bioaccumulation and/or toxicity) and prosing a dangerous to human health and agricultural products safety. Most studies on microplastics focus on single analyte exposure and transformation in the soil systems; the existing literature on joint environmental effects of microplastics and co-existing metals is rather limited. This paper summarized the current state of researches about microplastics and heavy metals and analyzed their interaction between them. The physiological response of terrestrial plants to complex pollution by microplastics and heavy metals has stated in this paper. In addition, future studies should explore the specific molecular mechanisms of microplastic co-exposure to plants, the effects on human health through the food chain, or the effects of co-action with other mixed pollutants and microplastic aging processes on the dynamic processes of heavy metal transport. |
