Particulate Matter from Diesel Vehicles: Emission and Exposure in Ireland

This project comprises an investigation of the impact of diesel vehicle emissions on the exposure of the population to PM2.5 and their subsequent health impacts. The project includes the collection of PM2.5 samples in location-specific microenvironments and among selected population subgroups to complement existing records of PM2.5 exposure. Source apportionment is also being conducted to identify the contribution of diesel emissions to the total mass of particles in different microenvironments. To extrapolate the results of the measurement campaign and existing data records to a large proportion of the population exposure models are being developed, building on a number of previous deterministic and statistical approaches recently developed for Dublin. The most suitable approach will be identified following performance comparison to conduct a PM2.5 population exposure assessment for Dublin based on time-activity profiles and census records A diesel vehicle emissions model will also be developed to assess the current and future impact of diesel vehicles on emissions at a local urban scale. These emissions and exposure models will enable the project to inform policy and develop solution to the environmental impact of diesel vehicles in Ireland.
