ClearDistribution of microplastics in the soils of a petrochemical industrial region in China: Ecological and Human Health Risks
Researchers surveyed microplastic contamination in soils across a major petrochemical industrial region in China and found concentrations ranging from 714 to over 11,000 particles per kilogram. Educational land had the highest contamination levels, and ecological risk assessments showed nearly all land-use types were at the highest risk level. The study also found that infants face significantly higher daily microplastic exposure than adults, underscoring the need for targeted pollution management in industrial urban areas.
Risks of microplastics in different land-use types of soil in a typical petrochemical city in China
Researchers surveyed microplastic contamination across different land-use types in Daqing, a major petroleum city in China, finding concentrations ranging from about 714 to over 11,000 particles per kilogram of soil. Industrial land posed the highest ecological risk, and infants were found to have significantly higher daily microplastic exposure than adults. The dominant plastics were rayon, polypropylene, and polyethylene, primarily in fiber form smaller than 1 mm.
Significant influence of land use types and anthropogenic activities on the distribution of microplastics in soil: A case from a typical mining-agricultural city
Scientists surveyed microplastic pollution across five types of land in a Chinese mining-agricultural city and found the highest levels in greenhouse farmland, with nearly 3,738 particles per kilogram of soil. Agricultural plastic waste, irrigation water, and fertilizers were identified as the main sources of contamination. The study shows that farming practices are major contributors to microplastic buildup in the soil that produces our food.
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.
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.
Examining Soil Microplastics: Prevalence and Consequences Across Varied Land Use Contexts
Scientists examined microplastic contamination in soil samples from different land use areas in Makassar City, Indonesia. They found microplastics present across all sites, with the types and concentrations varying based on how the land was used, whether for agriculture, residential, or commercial purposes. The study suggests that human activity patterns strongly influence the amount and kind of microplastic pollution found in urban and agricultural soils.
Microplastics occurrence and frequency in soils under different land uses on a regional scale
A regional-scale survey measured microplastic occurrence in soils under different land uses (agricultural, urban, natural), finding that concentrations varied by land use type and that real-world field concentrations were often lower than those used in laboratory ecotoxicology studies.
Subsurface transport and environmental risks of microplastic pollution: influence of land use and seasonal variability
Researchers systematically investigated how microplastics move vertically through soil across five different land use types during pre-monsoon and post-monsoon seasons. Dumpsites had the highest microplastic concentrations at nearly 40,000 particles per kilogram, while woodlands had the lowest at around 500 particles per kilogram. The study found that smaller microplastics traveled deeper into soil, especially after monsoon rains, and that land use type significantly influenced both the amount and composition of microplastic contamination.
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.
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.
Microplastics in soil: A comprehensive review of occurrence, sources, fate, analytical techniques and potential impacts
This review analyzed microplastic contamination data from 62 sites across 17 countries and found that soil microplastic levels varied enormously depending on land use, with agricultural and urban soils most contaminated. The plastics affected soil organisms, plants, and microorganisms in complex ways, but inconsistent sampling methods across studies make it difficult to compare results and determine safe exposure thresholds.
