Unrecognized volatile and semi-volatile organic compounds from brake wear
This study shows that volatile and semi-volatile organic gases are emitted during light and heavy braking. These emissions will remain as we transition to zero exhaust emission vehicles and must be included in air pollution and climate assessments.
Traceable determination of metal composition of tyres using tandem ICP-MS and benchmarking of emissions inventories
A robust validated method for analysis of metals in tyres using microwave digestion and ICP-MS/MS has been developed and used to estimate annual tyre wear emission rates.

Microplastic distribution and ecological risks: investigating road dust and stormwater runoff across land uses
This study in Melbourne, Australia, reveals higher levels of microplastic pollution in industrial areas compared to commercial or residential areas. Stormwater runoff is identified as the main pathway for transporting MPs from road dust to aquatic ecosystems.
Paper
Ultrafine particle emissions from dry clutches: number concentration, size distribution and chemical composition
Clutches in automobiles are shown to produce ultrafine particles, consisting of several metallic elements, which become airborne.
Paper
Induction of toxicity in human colon cells and organoids by size- and composition-dependent road dust
Environmental pollution, including the annual resurgence of particulate matter derived from road dust, is a serious issue worldwide.
About this collection
Non-exhaust emissions from road traffic, arising from the wear of vehicle parts (such as from the brakes, tyres and clutch), road wear and road dust resuspension, are an emerging issue for air quality and public health. This collection aims to improve our knowledge of the composition and quantity of these emissions, the current impact of such substances in the air we breathe and the potential of technological and non-technological mitigation measures
