英文摘要	Marine microplastic pollution considered as an emerging environmental problem has been highly recognized worldwide. Comparatively, no such attention has been paid on soil microplastic pollution especially in agricultural land. This paper reviews research progress in sources, accumulation, degradation, transport, and potential risks in eco-environment and food chain, and suggests relevant countermeasures in governance and research. It is also pointed out that microplastics may enter into the agricultural soils through various sources and pathways, including agricultural film breaking, organic manure application, water irrigation, sewage sludge utilization, atmospheric deposition, and surface runoff, and then accumulate in surface layer, while animal and possibly edible plants grown in soils, likely posing risks on ecosystem and food chain. However, the accumulation, forms, movement, degradation of microplastics in soil-animal-plant systems and their risks on eco-environment, food chain, and human health have been poorly understood. It is also lack of study and awareness in good measures for prevention, control, and remediation of microplastic pollution in soil. Therefore, the study also put forward to attach importance of research in microplastic pollution and treatment in soil for prevention of ecological and food chain risks. It is suggested that China should speed up the establishment of analytical methodology for soil microplastic study and accelerate deployment strategy for systematic research in soil microplastic pollution and treatment, aiming at understanding accumulation, release, transformation, and their eco-environmental effects of microplastics and corresponding additives and metabolites in soil, evaluating potential impacts of microplastics and its attached pollutants on risks to soil biotas, ecosystem, and food chain, and constructing technology systems for source control and remediation of microplastic pollution in soil. Thus, both scientific basis and technological support can be well provided for governance and treatment of microplastics in soil and terrestrial ecosystems in China.
中文摘要	海洋微塑料污染作为新型环境问题受到全球重视。相对地,土壤特别是农用地微塑料污染尚未引起广泛关切。文章综述了土壤中微塑料的来源、积累、降解、迁移及其生态环境和食物链的潜在风险等方面的研究进展,提出了相关的加强研究和监管对策建议。文章指出,农用地膜破碎、有机肥施用、污水灌溉、污泥农用、大气沉降以及地表径流等已成为土壤中微塑料的来源,可能导致土壤—食用性作物中微塑料积累和影响土壤生物行为。文章认为,对于进入土壤中的微塑料的存在形态、迁移、降解及其环境风险,在动植物中的积累及其生物生态、食物链的风险,进而对人体健康的风险等都还缺乏研究与了解;对如何加强土壤微塑料污染防控和修复,也缺乏探讨与意识。因而,文章提出要重视土壤中微塑料污染研究,以防范生态与食物链风险;并建议未来我国应加快土壤微塑料分析方法的建立,尽快部署开展土壤环境微塑料污染与治理研究,探明微塑料、添加物质及其降解产物在土壤环境中的积累、释放、转化及其生态环境效应,评估微塑料及其复合污染物对土壤生态系统、食物链和人体健康的风险,建立土壤微塑料污染的源头管控和修复技术体系,为土壤及陆地生态系统微塑料污染监管和治理提供科学依据和技术支撑。
