| 中文摘要: |
| 微塑料作为一种新型环境污染物，对土壤生态系统构成严重威胁。当前对微塑料的研究多集中于水域生态系统，而对土壤生态系统的影响研究较少。本文综述了土壤微塑料的分类及来源，分离、检测方法及存在问题，总结了土壤微塑料的污染和微塑料对污染物的吸附效应及机理，分析了其对土壤动物、微生物生态及碳、氮等物质循环的影响，最后针对微塑料的生态效应提出展望，为今后土壤微塑料的研究提供了新的思路。 |
| 英文摘要: |
| Microplastics are a new type of environmental pollutants characterized by their small particle size(<5 mm), wide distribution, and resistance to recovery. Owing to their long residue time in soil, microplastics can be accidentally ingested by soil fauna and, thereby, enter the food chain, which can subsequently influence the growth, development, and reproduction of soil fauna by damaging the organisms' organs and DNA. The toxins released during microplastic degradation and the absorption of environmental pollutants by microplastics also threaten soil ecosystems. Primary microplastics are derived from the raw material used for plastic production, whereas secondary microplastics result from the environmental degradation of large plastic products. As microplastics come from many sources, exist in many types, and are found in complex environments, they are difficult to be separated or detected. Recent studies have mainly focused on aquatic ecosystems and have rarely investigated the effects of microplastics on soil ecosystems. However, the plastic materials used in production and manufacturing are abundant, in both quantity and form, and some of these are released into soil systems. This review summarizes the classification, sources, sampling, and detection of microplastics, as well as related environmental problems, such as soil pollution, pollutant absorption, and effects on soil fauna, microbial ecology, and carbon and nitrogen circulation. The discussion of the ecological effects of microplastics could stimulate new ideas for future research. |
