ClearA Geochemical and Agronomic Evaluation of Technosols Made from Construction and Demolition Fines Mixed with Green Waste Compost
This study evaluated the agricultural and geochemical properties of soils made from mixtures of construction and demolition waste combined with green compost. While not directly about microplastics, construction and demolition materials are increasingly recognized as sources of microplastic contamination in recycled soil products.
Are anthropogenic soils from dumpsites suitable for arable fields? Evaluation of soil fertility and biomass response to elements
Researchers evaluated the fertility of anthropogenic soils developed from an abandoned dumpsite in Nigeria using multi-analytical approaches, measuring soil chemical signatures and bioaccessibility of elements to plant species, finding comparatively high Ca and Na content but raising questions about suitability for arable agriculture.
Potentially Toxic Trace Elements in the Urban Soils of Santiago de Compostela (Northwestern Spain)
Scientists measured potentially toxic metals (copper, lead, zinc, nickel, chromium, arsenic) in urban soils across the city of Santiago de Compostela, Spain, finding elevated concentrations in areas with heavy traffic and industrial activity. The study highlights how urban land use drives heavy metal contamination, which often co-occurs with microplastic pollution.
Are anthropogenic soils from dumpsites suitable for arable fields? Evaluation of soil fertility and transfer of potentially toxic elements to plants
Researchers evaluated the fertility of anthropogenic soils from an abandoned dumpsite in Nigeria, examining whether these soils are suitable for agriculture by measuring nutrient levels and the bioaccessibility of potentially toxic elements to plants.
Vegetation establishment in soils polluted by heavy metal(loid)s after assisted natural remediation
This field study evaluated soil remediation techniques at a mining spill site in Spain, finding that amendments made from recycled materials successfully reduced toxic metal availability and encouraged natural vegetation regrowth. While not about microplastics, the research demonstrates approaches for cleaning up contaminated soil that could also address microplastic pollution in agricultural land. The success of using waste-derived materials for soil restoration offers a model for sustainable approaches to multiple types of soil contamination.
Spatial and temporal variability of Cadmium and Lead in Urban Soils of Thessaloniki (northern Greece).
This study monitored cadmium and lead contamination in urban soils of Thessaloniki, Greece over two years, finding variable heavy metal levels linked to traffic and industrial activity. Heavy metals and microplastics frequently co-occur in urban environments and can interact to increase combined toxicity.
The role of microplastic pollution in the modification of the physicochemical properties of arable soil and uptake of potential toxic elements by plants
Researchers conducted a series of studies analyzing how microplastic pollution modifies the physicochemical properties of arable soil and affects the uptake of potentially toxic heavy metals by plants, beginning with a comprehensive literature review of microplastic interactions with plant physiology, metals, pesticides, and pathogens.
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.
Microbial responses towards biochar application in potentially toxic element (PTE) contaminated soil: a critical review on effects and potential mechanisms
Researchers reviewed how biochar — a charcoal-like material made from organic waste — can protect soil microorganisms from toxic heavy metal contamination by reducing metal availability and improving soil conditions. The review found that biochar addition consistently shifted microbial communities toward healthier, more diverse compositions, offering a practical soil remediation strategy aligned with sustainability goals.
Constructing Soils to Mitigate Land Occupation by Urban Expansion and Metabolism to Improve Healthy Cities
This review examines how engineered soils, known as technosols, can help mitigate the environmental impact of urban expansion by restoring soil functions in cities. Researchers discussed strategies for constructing soils that provide ecosystem services like stormwater management, carbon storage, and pollution filtration. The study highlights that building functional urban soils is an important tool for creating healthier and more sustainable cities.
Urban mining: Phytoextraction of noble and rare earth elements from urban soils
This review examines phytomining as a technology for recovering platinum group elements and rare earth metals from roadside soils contaminated by vehicle exhaust, catalytic converter wear, and road infrastructure. The authors synthesize research on metal accumulation sources, quantities, and plant species suitable for phytoextraction, presenting phytomining as a novel approach to urban resource recovery.
Organomineral fertilizer from sewage sludge: nutrient recycling and environmental safety for tropical agriculture
Not relevant to microplastics — this study evaluates an organomineral fertiliser derived from sewage sludge for tropical agriculture, focusing on nutrient recycling and heavy metal safety.
Effect of landfill leachates on urban soil: A review
This review examines how landfill leachate — which contains heavy metals, organic compounds, and emerging contaminants — affects urban soils, in the context of global concerns about the 1.4 billion tonnes of municipal solid waste deposited in landfills annually.
