ClearMicroplastic 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.
Ecological risk assessment of microplastics in agricultural soils of Coimbatore region, India
Researchers assessed the ecological risk of microplastic contamination in agricultural soils near Coimbatore, India, and found that soils treated with inorganic fertilizers had the highest risk levels. While overall pollution loads were categorized as low, the types of plastics found (including PVC and polystyrene) pushed risk scores into the extremely dangerous category due to their potential toxicity. The study raises concerns about how farming practices may be introducing hazardous microplastics into the soil where food is grown.

Microplastic Contamination in Agricultural Soils Across India: A Systematic Review of Studies and Research Gaps
This systematic review examines microplastic contamination in agricultural soils across India, an area that has received far less attention than waterways. The research identifies polluted irrigation water, industrial discharge, and plastic mulch as key contamination sources, raising concerns about microplastics entering the food supply through crops grown in contaminated soil.
Baseline assessment of microplastic contamination in agricultural soils from the coastal stretches of Karnataka and Goa, Southwestern India
Researchers assessed microplastic contamination in paddy field soils across coastal regions of Karnataka and Goa in India, finding microplastics in every sample tested at all depths up to 30 cm. Fibers and polypropylene particles were the most common types, likely originating from agricultural plastic use and atmospheric deposition. The presence of toxic heavy metals on the microplastic surfaces raises additional concerns about contamination of rice crops grown in these soils.
The extent and impacts of soil pollution by microplastics
This study examines the extent and impacts of soil pollution by microplastics, reviewing evidence of how microplastic particles accumulate in terrestrial environments and affect soil ecosystems, organisms, and agricultural systems.
Global concentrations of microplastic in soils, a review
This global review synthesized data from studies on microplastic concentrations in soils worldwide, finding contamination across diverse terrestrial environments with higher levels near urban areas and agricultural land. Terrestrial soils are estimated to contain far more microplastic than the world's oceans, making them a critical but understudied reservoir of plastic pollution.
Microplastics and mesoplastics as emerging contaminants in Tehran landfill soils: The distribution and induced-ecological risk
Researchers conducted the first study of microplastic and mesoplastic contamination in Tehran landfill soils, finding plastic particles in all 56 samples collected. Shallow soils had significantly higher concentrations than deeper layers, with most particles being low-density plastics from common single-use products. The calculated hazard indices reached levels III-IV, indicating moderate to high ecological risk from plastic pollution at the landfill site.
Preliminary results on microplastic pollution from agricultural soil in Vietnam: Distribution, characterization, and ecological risk assessment
This first microplastic survey of Vietnamese agricultural soils found concentrations ranging from 1,700 to 38,800 items per kilogram, with soils near residential areas and manufacturing facilities showing concentrations roughly five times higher than remote agricultural land. Fibers dominated and most particles were under 1 mm, with the majority of sites assessed at hazard level IV — the highest ecological risk category. The study establishes a critical baseline for a country where agricultural plastic use is intensive and growing.
Abundance, distribution, and ecological risks of microplastics in urban and agricultural topsoil of Mian-Ab Plain, Iran
Researchers mapped microplastic contamination across 102 soil samples in an arid Iranian plain using GIS mapping and advanced spectroscopy, finding the highest concentrations near urban centers and an average of nearly 12 microplastic particles per kilogram of soil. Children faced roughly double the estimated ingestion exposure compared to adults, and the dominant plastic types — PET, polystyrene, polypropylene, and nylon — pointed to mixed household and agricultural sources.
Spatial distribution of microplastics in soil with context to human activities: a case study from the urban center
Researchers mapped the spatial distribution of microplastics in topsoil across different land use types in an urbanized city in the upper Indus plain. They found that agricultural and urban areas had significantly higher microplastic concentrations than less developed areas, with fibers being the dominant particle type. The study links microplastic soil contamination patterns to specific human activities including irrigation with wastewater, plastic mulching, and industrial discharge.
Microplastics in soils: A review of methods, occurrence, fate, transport, ecological and environmental risks
This review examines the sources, detection methods, and environmental behavior of microplastics in soils, an area that has received far less attention than marine microplastic pollution. Researchers found that microplastics interact with soil properties and organisms in complex ways, potentially entering the human food chain. The study calls for standardized methods and more research into how these tiny plastic particles move through and affect terrestrial ecosystems.
Occurrence characteristics and ecological impact of agricultural soil microplastics in the Qinghai Tibetan Plateau, China
Researchers investigated microplastic pollution in agricultural soils on the Qinghai Tibetan Plateau in China, a remote area with low population density. They found microplastic concentrations ranging from about 17 to 950 particles per kilogram, with polyethylene terephthalate, polypropylene, and polyethylene being the most common types. The study suggests that facility-based agriculture significantly increases soil microplastic levels, and nearly half of the areas assessed showed relatively high polymer risk.
A global review on the abundance and threats of microplastics in soils to terrestrial ecosystem and human health
This review examines microplastic pollution levels across agricultural, roadside, urban, and landfill soils worldwide, finding wide variation but consistent contamination. Microplastics alter soil pH, density, and water movement, disrupt microbial communities, inhibit plant growth, and affect soil animals. For humans, the concern is that microplastics in soil can enter the food chain through crops and contaminated water.
Occurrence characteristics and risk assessment of microplastics in agricultural soils in the loess hilly gully area of Yan' an, China
Researchers measured microplastic levels in agricultural soil, water, and fertilizer in a farming region of central China and found an average of about 4,500 particles per kilogram of soil. Over 90% of the particles were smaller than 100 micrometers, and the main types were polyethylene and PET from sources like plastic mulch and compost. The findings show that farming practices are introducing significant microplastic contamination into the soil where food is grown.

Researchers surveyed microplastic contamination across multiple land-use types and found that greenhouse soils and residential areas had the highest concentrations, reaching up to 4,500 particles per kilogram. The study estimated that infants could face roughly 20 times higher daily microplastic intake than adults in heavily contaminated areas. The findings highlight the widespread variability of soil microplastic pollution and its potential health implications, particularly for vulnerable populations.
Microplastics pollution in rice fields: a case study of Pir Bazar rural district of Gilan, Iran
Researchers measured microplastic pollution in rice paddy soils in a rural area of northern Iran and compared them with non-paddy vegetable farms. Rice fields contained higher concentrations of microplastics, likely due to irrigation practices and plastic mulch use. The study found that fibers were the most common shape, and soil properties like organic matter content correlated with microplastic abundance, suggesting these particles could affect soil health over time.
