Vehicle exhaust pollution has had substantial press coverage recently as a result of Dieselgate and increased evidence of a range of health end points. However, non-exhaust emissions such as brake and tyre wear are currently estimated to contribute 50% of vehicle emissions in London and the health impact of these particles, relative to exhaust emissions, remain uncertain. In the future, as exhaust emissions are abated, these sources will become more important for both environmental policy development and human health impact. In the developing countries the resuspension from unpaved roads will also be a significant factor.
This project has two principal aims:
1. Identifying vehicle movements road by road in global cities by combining unique global high resolution satellite imagery, provided by the CASE partner (TCarter), and analysed using the application of AI, supported by medical image processing of the KCL School of Biomedical Engineering & Imaging Sciences.
2. The measurement of detailed PM species (high time resolution application of XRF and aerosol mass spectrometry) in cities with a range of climatology to develop non-exhaust emission factors and apply these to vehicle activity from 1 to inform the assessment of population exposure.
It is an exciting opportunity to undertake an interdisciplinary CASE studentship project in an expanding and world-leading team.
