The pervasive presence of microplastics has emerged as a pressing global environmental concern, posing threats to food security and human health upon infiltrating agricultural soils. These microplastics primarily originate from agricultural activities, including fertilizer inputs, compost-based soil remediation, irrigation, and atmospheric deposition. Their remarkable durability and resistance to biodegradation contribute to their persistent presence in the environment. Microplastics within agricultural soils have prompted concerns regarding their potential impacts on agricultural practices. Functioning as significant pollutants and carriers of microcontaminants within agricultural ecosystems, microplastics and their accompanying contaminants represent ongoing challenges. Within these soil ecosystems, the fate and transportation of microplastics can detrimentally affect plant growth, microbial communities, and, subsequently, human health via the food chain. Specifically, microplastics interact with soil factors, impacting soil health and functionality. Their high adsorption capacity for hazardous microcontaminants exacerbates soil contamination, leading to increased adverse effects on organisms and human health. Due to their tiny size, microplastic debris is easily ingested by soil organisms and can transfer through the food chain, causing physiological and/or mechanical damage. Additionally, microplastics can affect plant growth and have the potential to accumulate and be transported within plants. Efforts to mitigate these impacts are crucial to safeguarding agricultural sustainability and environmental health. Future research should delve into the long-term impacts of environmental aging processes on microplastic debris within agricultural soil ecosystems from various sources, primarily focusing on food security and human beings.
微塑料的普遍存在已经成为一个紧迫的全球环境问题，它们通过渗透到农业土壤中，对食品安全和人类健康构成威胁。这些微塑料主要来源于农业活动，包括肥料投入、基于堆肥的土壤修复、灌溉和大气沉降。它们具有显著的耐久性和抗生物降解性，这导致它们在环境中持续存在。农业土壤中的微塑料引起了人们对其潜在影响农业实践的担忧。作为农业生态系统中重要的污染物和微污染物的载体，微塑料及其伴随的污染物是持续存在的挑战。在这些土壤生态系统中，微塑料的命运和迁移会对植物生长、微生物群落产生不利影响，并通过食物链进而影响人类健康。具体而言，微塑料与土壤因素相互作用，影响土壤健康和功能。它们对有害微污染物的高吸附能力加剧了土壤污染，对生物和人类健康造成了更大的负面影响。由于其微小的尺寸，微塑料碎片很容易被土壤生物摄入，并通过食物链传递，造成生理和/或机械损伤。此外，微塑料可以影响植物的生长，并有可能在植物体内积累和迁移。为了保护农业的可持续性和环境健康，减轻这些影响至关重要。未来的研究应该深入研究各种来源的农业土壤生态系统中环境老化过程对微塑料碎片的长期影响，主要关注食品安全和人类健康。
