Measuring Children’s Exposure to PM2.5 : Setting up a Study for Bradford’s School Children

This paper describes a project that will deploy sensors that measure the concentration of particulate matter aerosol (PM2.5) in the air in ten primary school playgrounds in Bradford. This will provide an important opportunity to both (i) investigate the robustness and accuracy of the low-cost air pollution sensors, and (ii) establish a particulate matter aerosol measurement network in Bradford before the introduction of the Clean Air Zone (CAZ) for Bradford (currently under development, due late 2020). This is timely as few cities have had extensive aerosol monitoring systems in place before the implementation of a CAZ – it is an opportunity to collect data that would allow evaluation of the effectiveness of the CAZ, and inform research on the consequences for public health. The project is run in close collaboration with Born in Bradford, a birth cohort study that is tracking the health and wellbeing of 12,500 children in Bradford in an attempt to link adverse health outcomes with environmental aspects, in order to develop strategies to mitigate the effects. The static sensor costs in this project are funded by a Career Development Grant from the Aerosol Society.
