Global solar radiation received at ground level depends on short-lived climate forcer pollutants such aerosols, black carbon (BC), which is a form of soot, tropospheric ozone, and sulphate. Changes in the amount of insolation have important implications for climate change. Also, many of these climate forcer pollutants are considered to be harmful for the health of the population.
Megacities in developing countries are experiencing a fast level of economic development, with its associated increase in emissions of pollutants from power generation, traffic, industries and heating systems. Therefore, the detriment of air pollution in emerging megacities puts millions of people at risk of developing chronic cardio-respiratory and neurodegenerative disease and increasing hospital admissions.
Hence it is important to characterise the amount of concentrations of such short-lived climate pollutats, as well as their sources and estimated burden of disease. This information will provide evidence for policy makers in order to choose the best alternatives to set policies aimed at reducing the abundance of these climate forcers pollutants with implications both at the regional and global scale reducing megacities contribution to climate change, and reducing also the burden of disease associated with such pollutants.
Aerosol samples collected onto filters, concentration of ozone measured with passive samplers and meteorological factors will be monitored at several locations of a megacity. Sampling locations will be selected to be representative of different pollution sources (e.g. traffic and solid fuel indoor use). Local emission profiles typical of such sources will be characterised. Source apportionment using CMB and PMF will be performed such as to identify the major sources contributing to air pollution and inform best mitigation policies to reduce air pollution. Dose-response functions will be used to estimate the burden of disease associated with the short-lived climate forcer pollutants. The contribution to radiative forcing associated with the measured concentrations in the megacities will be also estimated.
Training and skills:
The student will join the UK largest active research group with interests in air quality-health impacts, atmospheric composition and chemistry. Due to the international nature of this research and the group’s international links, there will be possibilities for collaboration with partners at the international level.
The successful candidate will have a first or second upper level class honours degree in Environmental Sciences, Chemistry or a closely related field and preferably a master degree in a relevant discipline. Experience of field and laboratory work would be an advantage.
