Abstract

Abstract The agricultural sector is increasingly dependent upon the use of plastic products to enhance productivity. In addition to many incidental inputs, plastic fragments are progressively accumulating in soil following the degradation of plastic products. Microplastics (MPs, <5 mm) and nanoplastics (NPs, <1 µm) in agricultural soils have caused substantial concerns recently. The insidious interactions between plants, soil, and MPs/NPs in the agricultural environment could affect soil health, crop productivity, and threaten food safety and human health. Importantly, finer NPs can be taken up by plants, induce oxidative stress and negatively affect plant growth. Even though interactions of MPs/NPs with plants in the plant-soil nexus have been reported, a comprehensive review of the state of knowledge is lacking, which hinders continued progress in this emerging field. This review aims to fill the gap by extensively summarizing MPs/NPs sources in agriculture, techniques to investigate, impact on soil properties and accumulation in the plants. The synergistic effect of organic and inorganic co-contaminants and MPs/NPs are highlighted due to the widespread presence of these chemicals in agricultural soils. This review also presented possible mechanisms of MPs/NPs phytotoxicity. Although new information is emerging there is a paucity of data on the fate and impact of MPs/NPs in the plant-soil nexus. More efforts are needed to elucidate the fate and impact of MPs/NPs in agricultural soils to gain a deeper understanding of their health and safety implications. Graphical abstract

土壤-植物关系中的微塑料和纳米塑料:来源、吸收和毒性

摘要农业部门越来越依赖使用塑料制品来提高生产力。除了许多附带的投入外，随着塑料产品的降解，塑料碎片正在土壤中逐渐积累。微塑料（MPs，<5 mm）和纳米塑料（NP，<1 µm）最近引起了人们的极大关注。农业环境中植物、土壤和MPs/NP之间的潜在相互作用可能影响土壤健康、作物生产力，并威胁食品安全和人类健康。重要的是，更精细的NP可以被植物吸收，诱导氧化应激并对植物生长产生负面影响。尽管已经报道了MPs/NP与植物在植物-土壤关系中的相互作用，但缺乏对知识状况的全面审查，这阻碍了这一新兴领域的持续进展。这篇综述旨在通过广泛总结农业中MPs/NP的来源、调查技术、对土壤性质的影响和植物中的积累来填补这一空白。由于这些化学物质在农业土壤中的广泛存在，有机和无机共污染物以及MPs/NP的协同效应得到了强调。这篇综述还介绍了MPs/NPs植物毒性的可能机制。尽管新的信息正在出现，但关于MPs/NP在植物-土壤关系中的命运和影响的数据却很少。需要做出更多努力来阐明MPs/NP在农业土壤中的命运和影响，以更深入地了解其对健康和安全的影响。图形摘要

期刊介绍： Two of the most pressing global challenges of our era involve understanding and addressing the multitude of environmental problems we face. In order to tackle them effectively, it is essential to devise logical strategies and methods for their control. Critical Reviews in Environmental Science and Technology serves as a valuable international platform for the comprehensive assessment of current knowledge across a wide range of environmental science topics. Environmental science is a field that encompasses the intricate and fluid interactions between various scientific disciplines. These include earth and agricultural sciences, chemistry, biology, medicine, and engineering. Furthermore, new disciplines such as environmental toxicology and risk assessment have emerged in response to the increasing complexity of environmental challenges. The purpose of Critical Reviews in Environmental Science and Technology is to provide a space for critical analysis and evaluation of existing knowledge in environmental science. By doing so, it encourages the advancement of our understanding and the development of effective solutions. This journal plays a crucial role in fostering international cooperation and collaboration in addressing the pressing environmental issues of our time.
