Investigation on Microplastics in Soil near Landfills in the Republic of Korea
Researchers found microplastics in soil samples taken near two South Korean landfills, averaging 73–98 particles per kilogram, with polypropylene and polyethylene being the dominant types and fragments being the most common shape. The high proportion of secondary (weathered) microplastics indicates that fragmentation of larger plastic waste is actively occurring at these sites. These findings confirm that landfills are a significant local source of microplastic soil contamination and warrant inclusion in national monitoring programs.
Microplastics contamination in the soil from Urban Landfill site, Dhaka, Bangladesh
Researchers assessed microplastic contamination in soil samples from an urban landfill site in Dhaka, Bangladesh.

The study provides some of the first evidence of terrestrial microplastic pollution in Bangladesh and identifies urban landfills as significant reservoirs of soil microplastic contamination.
Investigating the amount of macro, meso, and microplastics in the surface soil around the landfill of Tabriz and the effect of the prevailing wind on their distribution
Researchers sampled soil around an improperly managed landfill in Tabriz, Iran, finding it heavily contaminated with microplastics — averaging 470 particles per kilogram of dry soil — along with larger meso- and macroplastic debris. Surprisingly, the prevailing wind had little influence on how the microplastics spread around the site; the pollution was widespread in all directions. Open and poorly managed landfills are a significant and underappreciated source of microplastic contamination in surrounding soils and communities.

Fibers made up 71% of particles and LDPE and HDPE plastics dominated, highlighting landfills as a major but overlooked source of microplastic pollution.
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.
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.
Characterization of Microplastics and Associated Heavy Metals in Urban Soils Affected by Anthropogenic Littering: Distribution, Spatial Variation, and Influence of Soil Properties
Researchers sampled soils across residential, commercial, and industrial land-use types in urban areas and found microplastics in every location, with polypropylene, polyethylene, and polyamide as the dominant polymer types, at concentrations up to 850,000 particles per kilogram. Heavy metals were also associated with the plastic particles, meaning microplastics in urban soil may serve as combined carriers of chemical toxicants. The findings highlight urban soil as a major but underappreciated reservoir of microplastic pollution.
Characteristics and potential risks of microplastics in the soil near landfill in Anyang, China
Soil samples collected around a large landfill in Anyang, China contained between 900 and 4,900 microplastic particles per kilogram, dominated by fibers and films smaller than 0.5 mm, with rayon and polypropylene as the most common polymers. Overall contamination was classified as moderate with low ecological risk, but soil texture was the main factor influencing how microplastics distributed themselves — not organic matter or pH. The results suggest landfills are meaningful point sources of soil microplastic contamination to surrounding land.
