The dual impact of tire wear microplastics on the growth and ecological interactions of duckweed Lemna minor
Researchers investigated how tire wear microplastics affect the growth and ecological interactions of duckweed, a common aquatic plant. They found that untreated and aged tire particles had the most harmful effects, reducing plant growth and impairing root development, while hydrated particles were less damaging. The study reveals that the condition of tire wear microplastics when they enter waterways significantly influences their impact on aquatic plant life.
Tire wear particles in different water environments: occurrence, behavior, and biological effects—a review and perspectives
This review examines tire wear particles, a major but often overlooked source of microplastics in water environments. Tire particles release toxic chemicals as they break down in water and can harm aquatic organisms, but most research has focused only on the chemical leachate rather than the particles themselves. Since tire wear contributes a large share of total microplastic pollution, understanding its full impact on water ecosystems and the food chain is important for human health.
Dual acute effects of tire microplastics and their leachates on Spirodela polyrhiza and phyllosphere bacteria
Researchers studied the effects of tire microplastics and their chemical leachates on duckweed, a common aquatic plant, and its associated bacteria. They found that both the particles themselves and the chemicals they release into water harmed plant growth, altered physiological responses, and shifted the bacterial communities living on the plant surfaces. The study reveals that tire-derived pollution affects aquatic ecosystems through multiple pathways beyond just the physical presence of plastic particles.
Ecotoxicology of micronized tire rubber: Past, present and future considerations
This review synthesizes what is known about the ecotoxicology of micronized tire rubber particles, which are increasingly identified as a significant fraction of environmental microplastics, examining their effects on aquatic and terrestrial organisms. The authors note that tire rubber contains a complex mixture of chemical additives that may drive toxicity beyond the physical effects of the particles themselves.
Comparative Toxicity of Micro, Nano, and Leachate Fractions of Three Rubber Materials to Freshwater Species: Zebrafish and .
Researchers compared the toxicity of micro, nano, and leachate fractions of three rubber materials—including tire rubber—to freshwater organisms. Nano-fractions and leachates generally showed higher toxicity than larger rubber particles, with leached chemicals driving much of the observed biological harm.
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.
Effects of tire wear particle on growth, extracellular polymeric substance production and oxidation stress of algae Chlorella vulgaris: Performance and mechanism
This study examined how tire wear particles, a common form of microplastic from roads, affect freshwater algae. Surprisingly, the tire particles actually promoted algae growth at certain concentrations while also causing oxidative stress. The findings suggest that tire-derived microplastics could disrupt the balance of aquatic ecosystems by altering algae behavior, which sits at the base of the food chain.
Acute toxicity of tire wear particles and leachate to Daphnia magna
Researchers tested the acute toxicity of tire wear particles and their chemical leachates on the freshwater organism Daphnia magna. They found that zinc and pyrene were the most abundant contaminants in the leachate, and that both the particles and their leachates caused significant immobilization and mortality. The study indicates that tire wear particles, increasingly recognized as a form of microplastic pollution, pose a real threat to freshwater aquatic life.

The Response of Duckweed Lemna minor to Microplastics and Its Potential Use as a Bioindicator of Microplastic Pollution
Researchers tested duckweed Lemna minor as a bioindicator for freshwater microplastic pollution by exposing it to polyethylene microbeads, tire wear particles, PET fibers, and natural particles. Polyethylene microbeads adhered to duckweed at 10 times the rate of other particles and reduced root length, suggesting duckweed could serve as a practical monitor for the dominant polyethylene microplastics in freshwater.
Chemical composition and ecotoxicity of plastic and car tire rubber leachates to aquatic organisms
Researchers tested chemical leachates from five types of common plastic and car tire rubber microplastics for their effects on algae and mussels. Car tire rubber and PVC produced the most toxic leachates, containing compounds like benzothiazole and zinc that significantly inhibited algal growth. The study reveals that the chemical additives leaching from degrading plastics may pose a greater immediate risk to aquatic organisms than the physical particles themselves.
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.
Effects of Polyester Fibers and Car Tire Particles on Freshwater Invertebrates
Researchers assessed the ingestion and effects of polyester fibers and car tire particles on four freshwater invertebrate species under acute and chronic exposure conditions. The study found that while both microplastic types were ingested by all species tested, car tire particles caused greater mortality in Daphnia magna and Hyalella azteca. The results suggest that the chemical composition of microplastics plays an important role in their toxicity to freshwater organisms.
