A study across different land-use types in China's Pearl River Delta found that agricultural land had higher soil microplastic concentrations than urban or forested areas, with land-use history and plastic mulch film use as the dominant factors controlling MP distribution and polymer composition.
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.
Microplastics abundance associated with farmland use types and the impact on soil microbial communities: A case study in Southern China
Researchers surveyed microplastic contamination across orchard, paddy field, and vegetable field soils in Southern China and analyzed how it affected soil microbial communities. They found microplastic levels ranging widely across sites, with very small particles under 30 micrometers being most common, and identified 32 different polymer types. The study shows that farmland use type and agricultural practices like plastic mulching significantly influence both the amount and type of microplastic contamination in soils.
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.
First insight into microplastic groundwater pollution in Latin America: the case of a coastal aquifer in Northwest Mexico
Researchers conducted the first investigation of microplastic pollution in groundwater in Latin America, analyzing six capped boreholes in a coastal aquifer in northwest Mexico for microplastic abundance, concentration, and characteristics.

The microplastics distribution characteristics and their impact on soil physicochemical properties and bacterial communities in food legumes farmland in northern China
Researchers surveyed farmland soil across five provinces in northern China and found microplastic contamination ranging from 1,600 to over 36,000 particles per kilogram of soil. Most of the microplastics were small fibers and fragments, primarily from agricultural plastic film and organic fertilizer use. The study found that microplastic presence altered soil properties and shifted bacterial community composition, suggesting these particles may affect soil health in food-growing regions.
Microplastics contamination and characteristics of agricultural groundwater in Haean Basin of Korea
Researchers investigated microplastic contamination in agricultural groundwater in Korea's Haean Basin, an area without nearby landfills or obvious pollution sources.

Researchers analyzed agricultural soils from the Hangzhou Bay coastal plain and found microplastic concentrations of 571 pieces/kg in mulched soils versus 263 pieces/kg in non-mulched soils, with irrigation water identified as an additional major source alongside mulch films. The findings point to multiple input pathways for microplastic accumulation in Chinese farmland soils.

Researchers analyzed groundwater from six coastal districts in a developing nation and found widespread microplastic contamination, with fibers and fragments of polyethylene and polypropylene being the most common types. Since groundwater is the primary drinking water source in many developing countries, this contamination represents a direct pathway for microplastic ingestion by millions of people.
Occurrence, distribution and affecting factors of microplastics in agricultural soils along the lower reaches of Yangtze River, China

Vertical distribution and multi-source pathways of microplastics in agricultural soils: A study of typical irrigation areas in the upper Yellow River basin
Researchers found that farmland soil in the upper Yellow River region contained significantly more microplastics than nearby forest or grassland, with plastics detected in all soil layers down to one meter deep. Flood-style irrigation pushed microplastics much deeper into the ground than drip irrigation, doubling contamination levels. This is concerning because microplastics migrating deep into agricultural soil could eventually reach groundwater that people depend on for drinking water.
