Unpaved road particulate matter emission rates and vehicle-induced transient plume characteristics

James Kacer, Ralph Altmaier, David M. Cwiertny and Patrick T. O'Shaughnessy

Particulate matter (PM) emitted from unpaved rural roads presents a potential inhalation hazard to people living and working near them.

Unrecognized volatile and semi-volatile organic compounds from brake wear

V. Perraud, D. R. Blake, L. M. Wingen, B. Barletta, P. S. Bauer, J. Campos, M. J. Ezell, A. Guenther, K. N. Johnson, M. Lee, S. Meinardi, J. Patterson, E. S. Saltzman, A. E. Thomas, J. N. Smith and B. J. Finlayson-Pitts

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

Emma C. Braysher, Andrew S. Brown, Richard J. C. Brown and Nick Molden

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

S. M. Alamgir Kabir, Muhammed A. Bhuiyan, Guomin Zhang and Biplob Kumar Pramanik

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.

Ultrafine particle emissions from dry clutches: number concentration, size distribution and chemical composition

Rikard Hjelm, Yezhe Lyu, Alessandro Mancini, Bozhena Tsyupa, Minghui Tu, Ulf Olofsson and Jens Wahlström

Clutches in automobiles are shown to produce ultrafine particles, consisting of several metallic elements, which become airborne.

About this collection

Non-exhaust substances 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 our environment and public health. This collection aims to improve our knowledge of the composition and quantity of these substances, their impact on our surroundings and the potential of technological and non-technological mitigation measures
