ClearPlastic Debrisin Agroecosystems: Distribution andAbundance Patterns, and Relationship with Terrain Characteristicsin Southeastern Brazil
Researchers surveyed plastic debris across forest, grassland, and agricultural land in a Southeast Brazil sub-basin, finding that agricultural areas accounted for 91.2% of total plastic waste with polypropylene, polyethylene, and PVC comprising 82.6% of polymers detected. Distribution strongly correlated with terrain characteristics, particularly slope and vegetation cover.
Assessment of Soil Microplastics and Their Relation to Soil and Terrain Attributes Under Different Land Uses
Researchers assessed microplastic contamination in tropical soils under different land uses including forest, grassland, and agricultural areas. They found that agricultural soils had the highest microplastic concentrations, likely due to the use of plastic-based materials in farming. The study reveals how land use practices and soil characteristics influence the distribution and accumulation of microplastics in tropical environments.

Microplastic appraisal of soil, water, ditch sediment and airborne dust: The case of agricultural systems
Researchers surveyed microplastic contamination across agricultural soils, water, airborne dust, and ditch sediments in farm settings with different management practices.

Assessing the impacts of land use and land cover on occurrence, spatial distribution of microplastics and heavy metals in an agricultural watershed, Tadepalligudem, Andhra Pradesh, India
Researchers mapped the occurrence and spatial distribution of microplastics and heavy metals in agricultural runoff from a watershed in Andhra Pradesh, India. They found an average of 41.7 microplastic items per liter, dominated by polypropylene and polyethylene fibers, with heavy metal concentrations of cadmium, arsenic, chromium, and lead posing varying levels of health risk. The study highlights that land use patterns significantly influence both microplastic and heavy metal contamination in agricultural water systems.
Impact of land-use patterns on soil microplastics: Distribution characteristics and driving factors in southern China’s Pearl River Delta
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.
Amount, distribution and composition of large microplastics in typical agricultural soils in Northern Germany
Researchers surveyed agricultural soils in Northern Germany for large microplastics and found contamination across all sampled fields, with polyethylene and polypropylene being the most common polymer types. Concentrations varied widely depending on farming practices, with fields receiving compost and sewage sludge showing higher contamination levels. The study provides important baseline data on microplastic pollution in European agricultural soils and identifies fertilization practices as a key contamination pathway.
Impact assessment of microplastics in agricultural soils of the Euroregion Galicia and Minho: preliminary results
Researchers assessed the impact of microplastic pollution on agricultural soils in the Euroregion Galicia-Norte Portugal, examining contamination levels across farmland as plastic use in agriculture intensifies globally. Microplastics were detected across sampled fields, with levels and types reflecting regional agricultural practices and plastic inputs.
Microplastics pollution modulated by farming regimes under multi-scenarios
Microplastic concentrations in agricultural soils were found to vary with farming regimes, with certain practices under mulching leading to higher accumulation. The study highlights how common agricultural methods contribute to soil microplastic pollution and supports calls for better plastic mulch management.
Microplastic diversity, risks and soil impacts: A multi-metric assessment across land-use systems
Researchers surveyed microplastic abundance, polymer diversity, and ecological risk across seven land-use types in India's Brahmaputra Valley, finding that built-up areas had the highest particle counts while forest soils paradoxically showed the greatest polymer hazard scores due to high-risk polymers, and that land-use type shapes both the quantity and composition of soil microplastic contamination.

Researchers surveyed microplastic contamination in soils across different land use types in Guizhou Province, southwest China. The study found that soil properties and land use patterns significantly influence microplastic abundance and distribution, with agricultural and urban soils generally showing higher contamination levels than less intensively managed areas.
