Project Description:

Atmospheric black carbon (BC) is receiving increasing attention from the climate change and air pollution health communities, but large gaps remain in our knowledge of BC sources. From the climate perspective, the short-term forcing effects of BC are providing an international impetus for abatement of BC sources.

From the health perspective, it has been suggested that BC is a better indicator of harmful airborne particulates from combustion sources (especially traffic) than particle mass concentration alone, and the recent reclassification of diesel exhaust as carcinogenic requires the development of specific tracers for these emissions.

This project will quantify different sources of urban BC to achieve a better understanding of BC at different spatial scales: from local to city-wide. The student will utilise existing regulatory and research measurement systems for novel purposes; developing new methods to divine source specific attributes of BC aerosol.

Policy Impact of Research:

Results from the project will be used in local and national government policies to decrease the health impacts of air pollution, by climate change researchers through better knowledge of urban BC emissions and by health effect researchers investigating the impacts of exposure to ambient BC.
