Abstract:
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.
摘要:
微塑料的普遍存在已经成为一个紧迫的全球环境问题,渗透农业土壤对粮食安全和人类健康构成威胁。这些微塑料主要来自农业活动,包括化肥投入,基于堆肥的土壤修复,灌溉,和大气沉积。它们显著的耐久性和抗生物降解性有助于它们在环境中的持续存在。农业土壤中的微塑料引起了人们对其对农业实践的潜在影响的担忧。在农业生态系统中充当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代表了持续的挑战。在这些土壤生态系统中,微塑料的命运和运输会对植物生长产生不利影响,微生物群落,and,随后,通过食物链实现人类健康。具体来说,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,导致对生物体和人类健康的不利影响增加。由于它们的尺寸很小,微塑料碎片很容易被土壤生物摄取,可以通过食物链转移,造成生理和/或机械损伤。此外,微塑料可以影响植物生长,并有可能在植物中积累和运输。减轻这些影响的努力对于维护农业可持续性和环境健康至关重要。未来的研究应该深入研究环境老化过程对各种来源的农业土壤生态系统内微塑料碎片的长期影响。主要关注粮食安全和人类。
