Researchers assessed microplastic and microrubber contamination in soils surrounding two landfills and a municipal solid waste transfer station near Ahvaz Metropolis, Iran, providing baseline data on particle abundance, morphology, and polymer types in Iranian waste management sites. The study found notable concentrations of both microplastics and microrubbers in surrounding soils, identifying landfills as significant local sources of these pollutants.
Environmental occurrence, fate, impact, and potential solution of tire microplastics: Similarities and differences with tire wear particles
This review examines tire microplastics, one of the most abundant types of microplastics in the environment, which come from tire wear on roads, recycled tire rubber, and tire repair dust. These particles carry a complex mix of chemicals including heavy metals and organic pollutants that can harm aquatic and soil organisms. Since tire microplastics end up in waterways and soil near roads, they represent a significant but often overlooked source of human microplastic exposure.

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.

Researchers systematically evaluated the toxicity of tire tread particles (TPs) from different brands on soil model species at environmentally relevant concentrations, identifying specific chemical determinants responsible for varying degrees of soil fauna toxicity across brands.
Occurrence and ecological risks of microplastics and phthalate esters in organic solid wastes: In a landfill located nearby the Persian Gulf
Researchers measured microplastic and phthalate ester contamination in organic solid waste at a landfill near the Persian Gulf in Iran. They found an average of 12.3 microplastic particles per gram of waste, with nylon being the most common type, along with measurable levels of phthalate chemicals. The study highlights that landfills can serve as significant sources of both microplastic and chemical pollutant release into surrounding environments.
A comparative analysis of the chemical composition and biofilm formation on tire wear particles from six different tire types
Researchers analyzed the chemical composition and biofilm communities forming on tire-wear particles compared to other microplastic types, finding that tire wear particles support distinct microbial assemblages. The unique surface chemistry of tire wear particles may promote the attachment of pathogens and toxin-producing microorganisms.
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.
Tire Wear Particles and Their Role in Microplastic Pollution
This review synthesized research on tire wear particles (TWPs) as a major but often overlooked source of microplastic pollution, contributing roughly six million tonnes annually. TWPs spread into soil, rivers, and oceans, where they carry toxic chemicals including heavy metals and PAHs, posing risks to wildlife and potentially entering the human food chain.
Tyre Wear Particles in the Environment: Sources, Toxicity, and Remediation Approaches
This review examines tire wear particles, which account for a major share of global microplastic pollution with 1.3 million metric tons released annually in Europe alone. These rubber-based particles contain heavy metals and toxic organic chemicals that contaminate air, water, and soil, and human exposure occurs through inhaling dust, eating contaminated food, and drinking water, raising concerns about respiratory, cardiovascular, and cancer risks.
Distribution and potential health impacts of microplastics and microrubbers in air and street dusts from Asaluyeh County, Iran
Researchers collected street dust and air samples from an industrial area in Iran and found significant quantities of microplastics and microrubber particles that could be inhaled or ingested by residents. The particles varied widely in size, color, and polymer type, with concentrations highest near industrial and urban zones. The study provides some of the first evidence that airborne microplastics in terrestrial environments represent a meaningful human exposure pathway.
Methods for laboratory-generation and physico-chemical characterisation of tyre wear particles
Researchers developed a lab method to generate tire wear particles using a friction machine and then identified a suite of chemical compounds that could serve as reliable markers for detecting these particles in environmental samples. Tire wear is one of the largest single sources of microplastic pollution globally, yet quantifying it in the environment has been hampered by the lack of agreed marker compounds. This work lays groundwork for standardized monitoring of tire particle pollution in soils and waterways.
Cotransport of 6PPD-Q and pristine/aged microplastics in porous media: An insight based on transport forms and mechanisms
Researchers investigated the cotransport of tire-derived chemical 6PPD-Q with pristine and aged microplastics through porous media. The study found that pristine microplastics adsorbed more 6PPD-Q than aged ones due to hydrophobic interactions, and that microplastics can facilitate the transport of this toxic tire rubber compound through soil and groundwater systems.
A hidden route of exposure: adsorption of endocrine disrupting compounds and chemicals of emerging concern on tire rubber
Researchers investigated how tire wear particles, a major source of microplastics in the environment, adsorb endocrine-disrupting compounds and other emerging contaminants. Using batch experiments and LC-MS/MS analysis, they found that sorption was rapid and compound-specific, with tire rubber efficiently retaining antibiotics, hormonal compounds, and hydroxylated PAHs, indicating tire particles may serve as hidden transport vectors for these pollutants.

Uptake of tire-derived compounds in leafy vegetables and implications for human dietary exposure
Scientists measured tire-derived chemicals in commercial leafy vegetables from four countries and found six different tire compounds present, including some linked to toxicity in aquatic life. Tire particles are one of the most common types of microplastic in the environment, and their chemical additives can be taken up by food crops through contaminated soil and water. While the estimated daily intake from vegetables alone was relatively low, this study confirms that tire-related microplastic pollution is entering the human food supply.
