ABSTRACT
This chapter focuses on the changing geographies of children's exposure to air pollution in developed world cities where air pollution is predominantly derived from transport emissions. It uses the term 'air pollution' to refer to the presence of an airborne substance that exceeds a level such that it is harmful to human health. The chapter focuses on common transport-related pollutants, including particulate matter (ultrafine particulates (UFP) and particulate matter less than 10 and 2.5 microns in diameter), nitrogen dioxide, carbon monoxide and volatile organic compounds such as polycyclic aromatic hydrocarbons and sulphur dioxide. It demonstrates how the exposure of children to air pollution changes with age and also in time and space. The chapter suggests that there is scope for exploring children's understanding of their own exposure to air pollution and the role of education as a tool for mitigating exposure.
