ClearParks and Recreational Areas as Sinks of Plastic Debris in Urban Sites: The Case of Light-Density Microplastics in the City of Amsterdam, The Netherlands
Researchers found that parks and recreational areas in Amsterdam act as significant sinks for light-density microplastics, with artificial turf infill, tire rubber, and film fragments as dominant types, suggesting urban green spaces accumulate substantial plastic pollution from recreational and maintenance activities.
Microplastics retained in rain gardens within different functional areas of Nanjing, eastern China
Researchers investigated microplastic retention in rain gardens across different functional areas of Nanjing, China, quantifying MP characteristics in these low-impact development stormwater management systems and evaluating their sources, finding that rain gardens can serve as significant sinks for urban microplastic pollution.
A preliminary comparison of microplastic type, size, and composition in atmospheric and foliage samples in an urban scenario
Researchers compared microplastic types, sizes, and polymer compositions in atmospheric dry and wet deposition at multiple sites, assessing contributions to ecosystem contamination. The results showed that atmospheric deposition is a significant pathway for microplastic redistribution, particularly to remote areas.
A preliminary comparison of microplastic type, size, and composition in atmospheric and foliage samples in an urban scenario
Researchers compared microplastic types, sizes, and polymer compositions in atmospheric dry and wet deposition samples from different settings. The study found that atmospheric deposition is a meaningful pathway for microplastic dispersal, with variation in particle characteristics across sites.
The urban microplastic footprint: investigating the distribution and transport
Researchers investigated the distribution and transport of microplastics within an urban environment, mapping the 'urban microplastic footprint' to understand how city infrastructure and land use patterns drive the spatial distribution and downstream export of plastic particles to receiving water bodies.
Anthropogenic-vegetation dual controls on the hotspots of microplastic pollution in urban green space soil
Researchers investigated microplastic and phthalate ester contamination in urban green space soils across diverse land uses in Guangzhou, China, finding average MP abundances of 2,117 items/kg with significant spatial variability. Residential areas, street edges, and heavily trafficked zones were identified as hotspots, with both human activity and vegetation type driving contamination patterns.
Comparison of microplastic type, size, and composition in atmospheric and foliage samples in an urban scenario
Researchers compared microplastic contamination in outdoor air deposits and on plant leaf surfaces in an urban area and found that both sampling methods detected similar types and sizes of microplastic particles. Fibers were the most common shape found, and polyester and polyethylene were among the most frequently identified polymers. The study suggests that plant foliage could serve as a practical biomonitor for tracking airborne microplastic pollution in cities.
[Distribution Characteristics and Risk Assessment of Microplastics in Water of Different Functional Parks in Guilin].
Researchers measured microplastic concentrations in the water of parks with different functions in Guilin, China. Microplastics were found in all park types, with concentrations varying based on human activity levels and proximity to pollution sources. Urban parks can serve as important monitoring sites for tracking microplastic contamination in freshwater environments.
Occurrence and risk associated with urban road-deposited microplastics
Researchers collected and analyzed microplastics deposited on urban roads and found average concentrations ranging from 0.33 to 3.64 grams per square meter, with significant variation based on land use and particle size. Road-deposited microplastics were mainly fibers and fragments from tire wear and textile sources, and their risk assessment indicated moderate ecological concern. The study provides new insights into how different urban environments contribute to microplastic pollution through road runoff.
Microplastic pollution in soil: a case-study from the Raffaele Viviani public park in Naples, Italy
This field study characterized microplastic contamination in soil samples from a public park in Naples, Italy, finding diverse polymer types at concentrations indicating that urban green spaces accumulate significant microplastic loads from atmospheric deposition and visitor activity.
Abundance and characteristics of microplastics in the surface water and sediment of parks in Xi'an city, Northwest China
Researchers surveyed microplastic pollution in urban park water bodies and sediments across Xi'an city, finding concentrations of 2,900-6,970 items per cubic meter in surface water, with distribution patterns linked to surrounding urban land use functions.
Microplastic pollution in urban green-belt soil in Shihezi City, China
Researchers found microplastic concentrations ranging from 287 to 3,227 particles per kilogram in urban green-belt soils in Shihezi City, China, with fibers dominating and polystyrene and polyethylene as the primary polymer types, pointing to atmospheric deposition and road runoff as key sources.
Microplastics in urban soils of Nanjing in eastern China: Occurrence, relationships, and sources
Researchers surveyed microplastics in urban green space soils across Nanjing, China, finding an average abundance of 461 particles per kilogram with fibers and fragments as the dominant forms. Source analysis linked microplastic patterns to nearby delivery and recycling activity points, suggesting that urban logistics infrastructure is an underrecognized microplastic source.
Microplastic contamination in an urban area: a case study in Greater Paris
Researchers investigated microplastic contamination across Greater Paris, finding that urban areas generate and accumulate substantial microplastic pollution through multiple pathways including stormwater, atmospheric deposition, and river transport.
Contributing to the assessment of the impact of urban activities on microplastic transport through air and runoff infiltration
Researchers investigated the contribution of urban activities to microplastic transport through both airborne pathways and stormwater runoff infiltration, quantifying plastic particle fluxes in an urban watershed. The study found that road surfaces, construction materials, and tire wear were significant urban sources, with rainfall events mobilizing microplastics into both air and subsurface water.
Children's playgrounds contain more microplastics than other areas in urban parks
Researchers measured microplastic contamination in sand, soil, and leaf samples from 19 children's playgrounds in Los Angeles urban parks. The study found that microplastic concentrations inside playgrounds were on average more than five times greater than in other park areas, with polyethylene and polypropylene being the most common polymers, suggesting that playground plastic structures may be a significant local source.
