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.
Behind conventional (micro)plastics: An ecotoxicological characterization of aqueous suspensions from End-of-Life Tire particles
Researchers studied the toxic effects of ground-up end-of-life tire particles on zebrafish larvae and found that finer tire powder was more harmful than coarser granules. The smaller particles released chemicals into the water that altered over 100 proteins involved in metabolic processes. The study suggests that recycled tire materials leach toxic substances that could pose risks to aquatic organisms.
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.
Toxicity of micro and nano tire particles and leachate for model freshwater organisms
Researchers tested the toxicity of micro- and nano-sized tire particles and their chemical leachates on zebrafish embryos and water fleas, two commonly used model organisms. They found that nano-sized tire particles were more toxic than micro-sized ones, and that the chemical leachate alone also caused significant developmental harm to zebrafish. The study demonstrates that tire debris poses a meaningful environmental risk to freshwater organisms through both direct particle exposure and the release of harmful chemicals.
Toxicity evaluation of microplastics to aquatic organisms through molecular simulations and fractional factorial designs
Researchers used molecular docking, molecular dynamics, and fractional factorial design to evaluate the toxicity of ten common microplastic types to zebrafish, identifying polystyrene and polyvinylchloride as the most toxic based on binding interactions with key biological proteins.

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.
Toxicity inhibition strategy of microplastics to aquatic organisms through molecular docking, molecular dynamics simulation and molecular modification
Researchers used molecular docking and dynamics simulations to study the combined toxic effects of microplastics and their chemical additives on zebrafish receptor proteins. They found that different microplastic-additive combinations produced widely varying toxicity levels, and identified hydrophobic forces, hydrogen bonding, and electrostatic interactions as the main drivers of protein binding. The study proposes a computational framework for screening lower-toxicity plasticizer formulations and designing more environmentally friendly plastic materials.
Risk assessment of tire wear in the environment – a literature review
This review assesses the environmental risks of tire wear emissions, which release microplastic-like particles containing polymers and potentially toxic chemicals into water and soil. While initial risk estimates suggest low risk from the particulate emissions themselves, the chemicals that leach from tire particles remain poorly characterized. The findings are relevant to human health because tire wear is one of the largest sources of microplastic pollution, and the leached chemicals may enter drinking water.
Tire wear particles in aquatic environments: A systematic review of sources, detection, distribution, and toxicological impacts
This systematic review examined tire wear particles — a type of microplastic created as tires wear down on roads — as an emerging water pollutant. These particles wash into rivers and oceans through stormwater runoff and contain toxic chemicals that harm aquatic organisms. Since tire wear is one of the largest sources of microplastic pollution, this is relevant to anyone living near roads or consuming seafood.
Tire wear particles in the aquatic environment - A review on generation, analysis, occurrence, fate and effects
Researchers reviewed available science on tire wear particles (TWP) — tiny fragments shed from tires during driving — finding that Europe alone generates over 1.3 million tonnes per year, but critical data on environmental concentrations, transport to waterways, and aquatic toxicity remain too limited for robust ecological risk assessment.
A study on the aquatic degradation of tire wear particles: Impact of environmental factors and material formulations
This study investigated how tire wear particles degrade in aquatic environments, examining the effects of environmental factors such as UV exposure and water chemistry on particle breakdown. The results showed that aquatic degradation alters tire wear particles in ways that may increase their ecotoxicological risk.

The study indicates that tire wear particles, increasingly recognized as a form of microplastic pollution, pose a real threat to freshwater aquatic life.
Deep dive into the chronic toxicity of tyre particle mixtures and their leachates
Researchers tested the toxicity of tire tread microparticles — shed from vehicle tires at roughly 1.4 kg per car per year — on water fleas (Daphnia magna) over 21 days and found the particles were nearly 10 times more toxic than chemical leachates from the same tires alone. Chemical analysis identified zinc, titanium, and 54 organic compounds shared across five major tire brands, with many classified as very toxic to aquatic life.
