ClearPlastic Debris in Agroecosystems: Distribution and Abundance Patterns, and Relationship with Terrain Characteristics in Southeastern Brazil
Researchers surveyed plastic debris across agricultural, grassland, and forest areas in southeastern Brazil and found that farmland accounted for over 91% of all plastic waste collected. Polypropylene, polyethylene, and PVC were the most common polymer types, and debris accumulation correlated strongly with terrain features like slope and vegetation cover. The findings highlight intensive agricultural practices as a primary driver of plastic pollution in agroecosystems.
Macro and microplastics in the soil: abundance, characterization, identification, and interactions under different land uses in an agricultural sub-basin
Researchers examined the abundance, characterization, identification, and interactions of macro- and microplastics in soils under different land uses within an agricultural sub-basin, assessing how land-use patterns influence plastic pollution distribution and potential interactions with the soil environment.
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.

A standardized survey of plastic pollution across 22 sandy beaches spanning over 4600 km of Brazilian coast found widespread contamination in coastal sediments, with polymer type, size, and distribution patterns reflecting diverse sources including fishing activity and urban runoff.
Spatial Distribution and Geostatistical Prediction of Microplastic Abundance in a Micro-Watershed with Tropical Soils in Southeastern Brazil
Researchers used geostatistical methods to predict and spatially map microplastic abundance in agricultural soil across a micro-watershed with tropical soils in southeastern Brazil. The study found heterogeneous spatial distribution patterns influenced by land use and topography, demonstrating that kriging-based interpolation can produce reliable continuous maps for environmental risk assessment.

Researchers surveyed microplastic contamination in agricultural soils across six sites in Coimbatore, India with distinct farming practices, finding microplastics in 81% of organic matter-removed samples. The study revealed that different agronomic inputs and land management practices produce distinct microplastic contamination profiles.
Effects of soil properties and land use patterns on the distribution of microplastics: A case study in southwest China
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.
Soil microplastic pollution under different land uses in tropics, southwestern China
Soil microplastic pollution was compared across four land use types in tropical southwestern China -- primary and secondary forests, rubber plantations, and banana plantations -- finding that agricultural land uses had higher microplastic abundance than natural forest soils.
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.
Preliminary Investigation of Microplastic Pollution in Agricultural Soil in Dong Anh District, Hanoi City
Agricultural soil samples from five sites in suburban Hanoi, Vietnam contained 494 to 1031 microplastic particles per kilogram of dry soil, with PET as the dominant polymer (38%) and fragments as the most common shape. The study provides baseline contamination data for a rapidly urbanizing agricultural region of Southeast Asia where plastic use and waste mismanagement are both growing. Documenting microplastic levels in food-producing soils is a critical first step for assessing dietary exposure risks for local populations.
Time Series approach to map areas of Agricultural Plastic Waste generation
Researchers applied a time-series remote sensing approach to map the spatial distribution of agricultural plastic waste generation across extensive agricultural landscapes, using satellite imagery to detect plastic-mulched farmlands and other agri-plastics to address the lack of comprehensive plasticulture data needed for effective waste management and land-use policy.

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. They found 11 types of microplastics in soil, with the highest concentrations in fields using plastic mulch, and documented the spread of particles into nearby water bodies and air. The study reveals that both plastic mulch and compost application contribute to microplastic pollution in agricultural landscapes.

Effects of land use on the distribution of soil microplastics in the Lihe River watershed, China
Researchers surveyed microplastic contamination across five different land use types in a Chinese river watershed. They found that urban soils had the highest microplastic levels, followed by agricultural areas, with woodland having the lowest, and that population density strongly correlated with microplastic diversity. The study suggests that human activity intensity and plastic waste disposal are the main drivers of soil microplastic pollution at the watershed scale.
