Microplastics, as a group of emerging contaminants, are receiving growing attention. During the last decade, their occurrence and toxicity in aquatic ecosystems have been intensively studied and reviewed, but less attention has been paid on soil ecosystems. Given the importance of soil ecosystems and the call for increasing research on soil from scientific communities, it is predicted that relevant studies will boom in the following years. The present review intends to provide a comprehensive overview of current knowledge on microplastic pollution in soil environments. We critically summarize the source, contamination level and fate of microplastics in (industrial and arable) soils. Then, we thoroughly describe what effects have been observed on soil microbes, animals and plants, and analyze what insights we can get from available information. Finally, we identify knowledge gaps that need to be filled and give suggestions for future research.
微塑料作为一类新兴污染物，正受到越来越多的关注。在过去十年中，它们在水生生态系统中的存在和毒性已得到深入研究和综述，但对土壤生态系统的关注较少。鉴于土壤生态系统的重要性以及科学界对增加土壤研究的呼吁，预计相关研究将在未来几年蓬勃发展。本综述旨在全面概述土壤环境中微塑料污染的现有知识。我们批判性地总结了（工业和耕地）土壤中微塑料的来源、污染水平和归宿。然后，我们详细描述了对土壤微生物、动物和植物的影响，并分析了从现有信息中可以获得的见解。最后，我们确定了需要填补的知识空白，并为未来的研究提出建议。
