ClearUptake of tire-derived compounds in lettuce under realistic growing conditions
Researchers grew lettuce under realistic agricultural conditions and measured uptake of tire-derived compounds including 6PPD-quinone and benzothiazole, finding detectable concentrations in plant tissues and raising food safety concerns about tire wear particle contamination in agricultural soils.
Co-exposure to tire wear particles and nickel inhibits mung bean yield by reducing nutrient uptake
Researchers grew mung bean plants for a full lifecycle in soil contaminated with tire wear particles and nickel, finding that tire particles alone reduced crop yields by up to 52%. When combined with high levels of nickel, a heavy metal, yields dropped by as much as 88%. This study shows that tire-derived microplastics in agricultural soil can significantly reduce food production and, when mixed with other pollutants, the damage is far worse than either contaminant alone.
Tire Wear Particles Inhibit Tomato Growth and Disrupt Rhizosphere Microbial Function
Scientists found that tiny particles from tire wear can seriously harm tomato plants, reducing their growth by more than half and disrupting the helpful bacteria in soil. The smallest tire particles (100 micrometers) were the most toxic, damaging the plants' ability to photosynthesize and creating harmful stress in their cells. This matters because these tire particles are everywhere in our environment and could reduce crop yields while making soil less healthy for growing the food we eat.
Tire abrasion particles negatively affect plant growth even at low concentrations and alter soil biogeochemical cycling
Researchers found that tire abrasion particles—a major source of microplastic pollution on land—negatively affected plant growth and disrupted soil nutrient cycling even at low concentrations. This is concerning because tire particles are shed in enormous quantities on roads and accumulate in roadside soils where plants grow.
The Influence of Microplastics from Ground Tyres on the Acute, Subchronical Toxicity and Microbial Respiration of Soil
Researchers assessed the toxicity of ground tire microplastics on soil organisms and microbial respiration, finding subchronic phytotoxicity effects that highlight the environmental risks posed by tire wear particles accumulating in soils.
Tire abrasion particles negatively affect plant growth even at low concentrations and alter soil biogeochemical cycling
Tire wear particles at environmentally relevant concentrations reduced plant growth, lowered seed germination rates, and altered soil nitrogen and carbon cycling biogeochemical processes even at the lowest doses tested, suggesting that tire-derived microplastics pose a real risk to terrestrial plant productivity and ecosystem function.
Beyond Microplastics: How Tire Wear Particles Influence Plant Performance
Scientists reviewed research on tiny particles that come off car tires when we drive, which end up in soil everywhere and are different from regular plastic pollution. These tire particles release toxic chemicals that can harm plants by damaging their roots and changing the soil around them, which could affect our food supply. This matters because tire pollution is everywhere but has been overlooked compared to other types of plastic pollution, and we need more research to understand the long-term risks to crops and ecosystems.
Integrating metabolomics and high-throughput sequencing to investigate the effects of tire wear particles on mung bean plants and soil microbial communities.
Tire wear particles at realistic concentrations (0.1-1.5% soil weight) inhibited mung bean growth, altered root metabolite profiles, and shifted soil microbial community structure, indicating that road-derived plastic contaminants can disrupt soil-plant systems in agricultural settings.
Impact of tyre wear particles and tyre leachate on the freshwater angiosperm Lemna minor
Researchers tested the ecotoxicity of tyre wear particle leachate on the aquatic plant Lemna minor and measured TWP uptake into plant tissues, finding that leachate posed meaningful risks to aquatic plants while direct TWP incorporation into plant biomass was limited, suggesting leachate management is the priority concern.
Chemical toxicity screening of tire particle leachates from vehicles and their effects on organisms across three trophic levels
Researchers prepared leachates from bicycle, car, and electric scooter tire particles and tested toxicity across three organisms, finding that zinc and benzothiazole were the primary toxic compounds and that tire particle leachates caused growth inhibition in plants, mortality in water fleas, and developmental abnormalities in zebrafish.
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.
Priorities to inform research on tire particles and their chemical leachates: A collective perspective.
An international interdisciplinary network of researchers identified priority research areas for understanding the ecological impacts of tire particles and their chemical leachates — a rapidly growing area of concern given that tire wear particles are one of the largest sources of microplastics in urban runoff. The priorities span toxicology, exposure assessment, and regulatory relevance.
Comparison of the effects of tire wear particles on the freshwater macrophyte under different exposure scenarios
Researchers compared the effects of tire wear particles on the freshwater macrophyte Lemna minor and other aquatic plants, examining how the complex composition of tire-derived microplastics affects plant growth and physiology. Tire wear particles showed toxicity to aquatic plants at environmentally relevant concentrations, with chemical leachates contributing to the observed effects.
Brand-Specific Toxicity of Tire Tread Particles Helps Identify the Determinants of Toxicity.
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.
A critical review of tire wear particles aging and ecotoxicological consequences in terrestrial environments: Insights into environmentally persistent free radicals
This review synthesizes evidence on how tire wear particles age in terrestrial environments and the resulting ecological consequences. Researchers found that UV-induced aging generates environmentally persistent free radicals and reactive oxygen species that amplify soil toxicity, while biodegradation may reduce some risks. The study highlights that characterizing aged tire wear particles remains difficult due to their compositional complexity and calls for standardized analytical methods.
Comparison of the effects of tire wear particles on the freshwater macrophyte under different exposure scenarios
Researchers compared effects of tire wear particles on the freshwater macrophyte Lemna minor and other aquatic plants, examining how tire-derived microplastics with their complex rubber and additive composition affect primary producers. Tire wear particles inhibited aquatic plant growth, with both the rubber particles themselves and leachate chemicals contributing to phytotoxic effects.
Tire wear particles: An emerging threat to soil health
This review synthesizes knowledge about tire wear particles — a major but often overlooked source of microplastic-like pollutants — in soil ecosystems. Tire wear particles contain toxic metals and organic compounds that harm soil microbes, invertebrates, and plants, but most research to date has focused on aquatic systems rather than soils.
[Effects of Tire Wear Particles on Seedling Growth of Kidney Bean （Phaseolus vulgaris L.） and Soil Antibiotic Resistance Gene Abundance].
Researchers studied how tire wear particles, a major source of microplastics, affect kidney bean seedling growth and antibiotic resistance genes in soil. The study found that tire wear particles impaired root development by up to 49% and fresh weight by up to 48%, while also significantly increasing the abundance of antibiotic resistance genes in soil, including high-risk genes linked to drug-resistant bacteria.
Uptake, Metabolism and Accumulation of Tire Wear Particle-Derived Compounds in Lettuce.
This study exposed lettuce plants to tire wear particle-derived chemicals — including 6PPD and its toxic transformation product 6PPD-q — in hydroponic solution and found that plants took up and partly metabolized these compounds. The results raise food safety concerns about tire-derived chemical contamination of vegetables grown with runoff-influenced irrigation water.
Time-Dependent Toxicity of Tire Particles on Soil Nematodes
