[Distribution, Sources, and Behavioral Characteristics of Microplastics in Farmland Soil].
Summary
This systematic review summarizes existing research on how microplastics distribute, accumulate, and move through farmland soils worldwide. The study found that microplastics in agricultural soil come mainly from plastic mulch films, fertilizers, and irrigation water, with fibers and fragments being the most common shapes detected. Since farmland microplastics can be taken up by crops, this contamination pathway is a direct route for microplastics to enter the human food supply.
Microplastics (MPs) are widely present in farmland soil as an emerging contaminant. This paper serves as a comprehensive and systematic review of research progress on the characteristics of distribution, abundance, sources, shape, polymer composition, size, and migration of MPs in farmland soils around the world. Moreover, research prospects were also proposed. MPs have been detected in farmland soils around the world, mainly coming from agricultural plastic films, organic fertilizers, sludge, surface runoff, agricultural irrigation, atmospheric deposition, and tire wear particles. The morphology of MPs in soil mainly includes debris, fibers, and films. MPs polymer forms mainly include polyethylene, polypropylene, and polystyrene. Farmland land use significantly affects soil MPs abundance. Additionally, the abundance of MPs increase with the reduction in size. MPs in soil can migrate to deep soil through tillage, leaching, bioturbation, and gravity. Research on soil MPs detection methods, database establishment, safety thresholds, migration and transformation laws, potential ecological health risk assessment, and the construction of prevention and control technology systems should be strengthened in the future. The paper can provide a reference for the risk control and governance of farmland soil MPs pollution.

Microplastics in the agricultural soils: Pollution behavior and subsequent effects
This review summarizes existing research on how microplastics accumulate in farmland through fertilizers, irrigation, plastic mulch, and atmospheric fallout. Microplastics change soil structure, harm beneficial microbes, and can be taken up by crops, moving through the food chain to humans. The authors emphasize that more research is needed to understand the long-term health risks of eating food grown in microplastic-contaminated soil.

Activities of Microplastics (MPs) in Agricultural Soil: A Review of MPs Pollution from the Perspective of Agricultural Ecosystems
This review summarizes the origins, migration, and fate of microplastics in agricultural soil ecosystems, identifying plastic mulch film, irrigation water, and organic fertilizers as major sources. The study highlights that microplastic accumulation in farmland can affect soil structure, microbial communities, and crop growth, with potential implications for food safety through the terrestrial food chain.
Sources, environmental fate, and impacts of microplastic contamination in agricultural soils: A comprehensive review
This review examines how microplastics from fertilizers, irrigation, and atmospheric fallout are contaminating agricultural soils worldwide. Once in the soil, microplastics interact with soil organisms, disrupt plant growth, and can carry other harmful chemicals deeper into the environment. Because these tiny plastics can move up the food chain, they represent a growing threat to both food safety and human health.
Characteristics and Migration Dynamics of Microplastics in Agricultural Soils
This review summarizes 30 years of research on microplastic pollution in agricultural soils, covering how these particles enter farmland through mulch films, irrigation water, and atmospheric deposition. Researchers found that microplastics can alter soil structure, affect microbial communities, and influence crop growth in various ways. The study highlights the need for standardized methods to measure and manage microplastic contamination in farming systems.
