Abstract

Plastic particles smaller than 5 mm are known as microplastics, and they are becoming a major ecological and environmental hazard in agricultural soils. These particles come from a variety of sources, such as atmospheric deposition, wastewater irrigation, the breakdown of plastic mulches, and the use of biosolids. Once in the soil, microplastics change the microbial communities, water retention, and soil structure through interactions with physical, chemical, and biological processes. They may worsen soil contamination and possibly introduce harmful substances into the food chain by serving as vectors for organic pollutants and heavy metals. Sustainable agriculture is threatened by the presence of microplastics in agricultural soils, which also endanger crop productivity, ecosystem services, and soil health. Reducing plastic use, switching to biodegradable substitutes, improving waste management procedures, and creating cutting-edge technologies for the removal of microplastics are all examples of mitigation techniques. In order to protect soil health and agricultural sustainability, this review examines the causes, effects, and mitigation techniques of microplastics in agricultural soils, highlighting the necessity of coordinated research and policy interventions.

农业土壤中的微塑料：来源、影响和缓解战略

小于5毫米的塑料颗粒被称为微塑料，它们正在成为农业土壤中的主要生态和环境危害。这些颗粒有多种来源，如大气沉降、废水灌溉、塑料覆盖物的分解和生物固体的使用。一旦进入土壤，微塑料就会通过与物理、化学和生物过程的相互作用改变微生物群落、保水和土壤结构。它们可能加重土壤污染，并可能作为有机污染物和重金属的载体，将有害物质引入食物链。农业土壤中微塑料的存在威胁着可持续农业，它还危及作物生产力、生态系统服务和土壤健康。减少塑料的使用、改用可生物降解的替代品、改进废物管理程序以及创造去除微塑料的尖端技术都是缓解技术的例子。为了保护土壤健康和农业可持续性，本文综述了农业土壤中微塑料的原因、影响和缓解技术，强调了协调研究和政策干预的必要性。图形抽象

期刊介绍： Environmental Monitoring and Assessment emphasizes technical developments and data arising from environmental monitoring and assessment, the use of scientific principles in the design of monitoring systems at the local, regional and global scales, and the use of monitoring data in assessing the consequences of natural resource management actions and pollution risks to man and the environment.
