Particulate Matter from Non-exhaust Sources

Analytical Investigation of Tire Induced Particle Emissions

This automotive engineering study measured the size distribution of fine dust particles (under 10 micrometers) generated by tire wear, finding that tire-derived particles represent a significant non-exhaust source of urban particulate matter. As electric vehicle adoption reduces exhaust emissions, tire and brake wear particles will become a proportionally larger component of urban air pollution. These tire wear particles are also a major source of microplastic contamination in road runoff.

Characterisation of non-exhaust emissions from road traffic in Lisbon

Researchers characterized road dust particles in Lisbon, Portugal, finding that brake and tyre wear contribute high levels of copper and zinc to street surfaces, and that arsenic levels in road dust exceeded safe cancer risk thresholds on 90% of sampled streets. The findings highlight the underappreciated health risks from non-exhaust traffic emissions — particles released not from engines but from road surfaces, tires, and brakes — which also contribute to microplastic pollution.

Markovian city-scale modelling and mitigation of micro-particles from tires

This modeling study estimated tire wear particle emissions at a city scale, finding that as vehicle fleets electrify and tailpipe emissions decline, non-exhaust emissions from tire and brake wear will become the dominant form of traffic-related particulate pollution. Because tire wear particles contain microplastics and toxic chemicals, this shift raises serious public health concerns that warrant stronger regulatory attention.

The problem of emission of total particulate matter and heavy metals from tribological systems in vehicles

Researchers measured total particulate matter and heavy metal emissions generated by tribological contact — friction and wear between mechanical components — finding that brake and tire wear produces significant airborne particle loads containing lead, copper, zinc, and other metals. The results underscore tribological wear as a major non-exhaust source of urban air pollution.

Tyre and road wear particles (TRWP) - A review of generation, properties, emissions, human health risk, ecotoxicity, and fate in the environment

This comprehensive review compiles current knowledge on tyre and road wear particles, which are generated during driving and contribute to both airborne emissions and microplastic pollution.
