This thesis takes a multi-scale approach to addressing the issue of air quality and human health impacts attributable to aviation. In particular, processes at the exhaust plume (~ 1 km), local (~ 10 km), regional (~ 1000 km) and global (~ 10 000 km) scale are addressed. At the plume scale, a three-dimensional integral plume model is developed and applied to elucidate aspects of near-field dispersion processes. A new method for approximating dispersion at the local scale is developed, which allows the air quality in the vicinity of large numbers of airports to be rapidly estimated. At the regional and global scales, an atmospheric chemistry-transport model is adapted to understand the intercontinental transport of aircraft pollution. This thesis includes the first estimate of the number of premature mortalities attributable to aviation worldwide. A key finding is that aircraft cruise emissions are more important in terms of their total public health impacts than landing and takeoff (LTO) emissions. On this basis, it may be appropriate to change aircraft emissions regulations, which currently only cover LTO emissions on the assumption that cruise emissions do not degrade air quality.
