ClearMicroplastics pollution in the soil mulched by dust-proof nets: A case study in Beijing, China
Researchers investigated microplastic pollution in soils covered by dust-proof nets used on construction sites in Beijing, China. They found that the nets themselves were a source of microplastic contamination, with fiber-type particles being the most abundant in the underlying soil. The study identifies construction site dust-control measures as a previously overlooked source of microplastic pollution in urban soils.
Assessment of microplastic release from geofabrics used in erosion control at construction sites
Construction sites using polyester geofabric for erosion control were found to shed an estimated 1.7 million PET microplastic fibers per rain event into nearby waterways, even when stormwater management systems captured more than 90% of particles. The study demonstrates that geofabrics — a largely overlooked source — can be a substantial contributor to urban microplastic pollution, and that existing best management practices are insufficient to prevent millions of fibers from reaching aquatic environments during each major rainfall.

The Source, Distribution Characteristics,and Migration Behavior of Microplastic Pollutionin Soil Environment in China: A Review
Researchers reviewed how microplastics enter Chinese soils — mainly through plastic mulch films, sewage irrigation, and fertilizer application — and how they migrate through soil layers while carrying other pollutants with them. The review highlights that China's intensive agricultural practices make its soils among the most microplastic-contaminated on Earth, with implications for food safety and groundwater quality.
Microplastics pollution in the soils of various land-use types along Sheshui River basin of Central China
Soils from four land-use types along a Chinese river basin were found to contain microplastics at all sites, with plastic greenhouse soils showing the highest concentrations, and fiber shapes dominating across land uses, reflecting widespread agricultural plastic use as a primary source.
Abundance and characteristics of microplastics in soils with different agricultural practices: Importance of sources with internal origin and environmental fate
Microplastic abundance and characteristics were examined in soils representing four agricultural practice types in Chinese farmland to evaluate the influence of land use on plastic particle accumulation. Microplastic concentrations and polymer types varied by agricultural practice, with plastic mulch film use and irrigation water source as key drivers of farmland soil contamination.
Estimation of soil microplastic input derived from plastic gauze using a simplified model
Researchers developed a simplified estimation model combining remote sensing with field data to quantify microplastic input into soils from degrading plastic gauze used in haze prevention and agriculture in the Beijing-Tianjin-Hebei region of China.
Current research and perspective of microplastics (MPs) in soils (dusts), rivers (lakes), and marine environments in China
This review synthesized a decade of Chinese research on microplastic concentrations in soils, rivers, lakes, and marine environments, finding that coastal and urban areas are most contaminated and that freshwater environments are understudied compared to marine ones. China, as the world's largest plastic producer, faces significant microplastic pollution challenges requiring systematic monitoring across all environmental compartments.
Transport and fate of microplastics from riverine sediment dredge piles: Implications for disposal
Analysis of dredged river sediment piles in southeast China found high MP concentrations (6,060–37,610 items/kg), and monitoring of surrounding soils and surface waters showed that dredging and stockpiling remobilized these MPs into adjacent agricultural land and waterways — a previously unrecognized dispersal pathway.
The synchronized dynamic release behavior of microplastics during farmland soil erosion process
Field and laboratory experiments on farmland soil in coastal China showed that roughly half of the microplastics present in agricultural soil can be mobilized and released into water bodies during erosion events. The dynamic release pattern — an initial decrease followed by a sharp increase — is driven by competition between particle adsorption, sedimentation, and resuspension, highlighting that controlling soil erosion is a critical and underappreciated lever for preventing microplastic contamination of rivers and coastal waters.
Distinct microplastic distributions in soils of different land-use types: A case study of Chinese farmlands
Microplastic distribution across six types of farmland land use was surveyed from soils in five Chinese provinces to determine how agricultural practices shape soil microplastic contamination. The study found that microplastic abundance varied significantly by land-use type, with plastic mulch film use and irrigation practices as key contributing factors.
Microplastics in agricultural soils in China: Sources, impacts and solutions
This review examines microplastic contamination in Chinese agricultural soils, finding abundances ranging from about 5 to over 40,000 items per kilogram depending on location. The study identifies plastic mulching films as the most significant source, followed by abandoned greenhouses and organic fertilizers, and recommends sustainable agronomic practices to reduce soil microplastic pollution.
Exploring the unintended contribution of soil erosion research to microplastic contamination
Researchers raised an overlooked problem: the plastic equipment and containers routinely used in soil erosion research inadvertently shed microplastics into the very samples being studied, contaminating data and the environment around test plots. They call for researchers to revisit their methods and minimize plastic use during sampling, transport, and lab analysis to get cleaner results.
Microplastic pollution in urban green-belt soil in Shihezi City, China
Researchers found microplastic concentrations ranging from 287 to 3,227 particles per kilogram in urban green-belt soils in Shihezi City, China, with fibers dominating and polystyrene and polyethylene as the primary polymer types, pointing to atmospheric deposition and road runoff as key sources.
Analysis of the generation of plastic debris and microplastics from geosynthetics
This paper critically analyzes claims linking geosynthetic materials to microplastic generation, arguing that the environmental benefits of geosynthetics — such as preventing erosion and improving waste containment — far outweigh the minimal plastic debris they produce compared to alternative materials. The work is relevant to microplastic research by quantifying geosynthetics as a relatively minor source compared to other plastic pathways.
[Distribution Characteristics and Risk Assessment of Microplastics in Soil in Danjiangkou Reservoir Area of South-to-North Water Diversion Project].
This study characterized microplastic occurrence in four types of agricultural soil in the Danjiangkou Reservoir area of China — a critical water source for the South-to-North Water Diversion Project. Orchard soils had higher microplastic concentrations than paddy or dryland soils, driven by plastic mulch use and irrigation. Microplastic contamination of this major water supply raises concerns about downstream drinking water quality for millions of people.

The distribution of microplastics in soil aggregate fractions in southwestern China
Researchers investigated microplastic distribution across different soil types in agricultural and forested areas near a lake in southwestern China and found plastic particles in every sample, with concentrations as high as 42,960 particles per kilogram. Approximately 95% of the particles fell within the microplastic size range, and fibers were the dominant form, likely originating from textiles and agricultural materials. The study demonstrates that microplastic contamination in soils is extensive and varies with land use practices.
