【摘要】 微塑料(microplastics, MPs)是一种新型环境污染物,不仅危害海洋生态系统,也广泛存在于陆地生态系统,可以通过土壤进入植物体,进而危害人类健康。该文系统综述了农田环境中MPs的研究进展及未来方向。详细介绍了国内外土壤中MPs的形态、来源、积累过程及MPs对土壤结构和功能的影响;重点阐述了MPs对生物、植物的生态影响以及MPs和金属镉复合污染对植物的影响;并展望了农田环境中的MPs研究的未来方向及重点,以期为全面了解农田中MPs研究现状及未来研究提供信息和科学指导。更多还原

【Abstract】 This paper is to make a comprehensive and systematic review of research progresses and future directions of the study on microplastics in the farmland environment, to introduce morphology, sources and accumulation of microplastics(MPs), and effects of MPs on structure and function in the soil both in China and in other countries as well. This paper also elaborates ecological effects of MPs on organisms, plants and the effects of MPs and cadmium compound pollution on plants. In the end, the paper puts forward views and prospects of future researches on microplastics in the farmland environment. This paper is expected to be able to provide information and scientific guidance for comprehensive understanding of the presence and future of microplastics in the farmland environment.更多还原
