Measurement of Traffic-related atmospheric hydrocarbon concentrations
- Project Team:
- Project Leader: Brian Broderick
- Description:
-
Motor vehicles emit a variety of atmospheric pollutants. Amongst these are a variety of hydrocarbons, including benzene, the ambient concentrations of which are to be limited by recent EU directives.
The initial stage of this project involves the on-line measurement of ambient hydrocarbon concentrations in the vicinity of a motorway and at a busy junction in Dublin city centre. At these locations, concentrations of many hydrocarbons can, in the main, be attributed to road-traffic emissions.
The second part of the project entails adapting the on-line system to accommodate a more flexible, portable and mobile sampling method based on the use of tedlar bags as sampling vessels. Once validated, this method will facilitate a wide range of sampling applications, such as the measurement of background concentrations, emission factors and the spatial distribution of pollution levels.
The final project stage will involve the application of this “mobile sampling” method. Spatial mapping of Dublin city along with “real world” driving emissions are topics currently being reviewed as potential areas of research.
