Microplastics (MPs) and nanoplastics (NPs) have been widely studied, mostly focusing on the methods of separation, detection, and adsorption or the ecological effects in aquatic ecosystems. When different sources and types of MPs/NPs enter the soil, they can affect the biogeochemical cycle in terms of the direct impacts on soil physicochemical properties and soil organisms, and the indirect impact on soil biota through changes in soil material cycling. To date, a few studies have focused on the effects of MPs/NPs on soil ecosystems, including soil properties, microbial communities, soil fauna, and plants, as well as the potential or affirmed correlations among them. In this review, we summarized the recent literature on soil MPs/NPs focusing on their types, sources, separation, and ecological impacts on soil properties, microbes, and plants. We attempted to establish an overall relationship between MPs/NPs and soil plant system. Based on existing studies, we also highlight the research gaps and propose several directions for future studies.
微塑料(MPs)和纳米塑料(NPs)已经得到了广泛的研究,主要集中在分离、检测和吸附方法上,或者在水生生态系统中的生态效应上。当不同来源和类型的 MPs/NPs 进入土壤时,它们可以通过直接影响土壤理化性质和土壤生物,以及通过改变土壤物质循环间接影响土壤生物区系,从而影响生物地球化学循环。迄今为止,少数研究集中在 MPs/NPs 对土壤生态系统的影响上,包括土壤性质、微生物群落、土壤动物和植物,以及它们之间的潜在或确定的相关性。在这篇综述中,我们总结了最近关于土壤 MPs/NPs 的文献,重点关注它们的类型、来源、分离和对土壤性质、微生物和植物的生态影响。我们试图建立 MPs/NPs 与土壤植物系统之间的整体关系。基于现有研究,我们还强调了研究差距,并提出了未来研究的几个方向。
