Tracers and Dispersion Of Gaseous Pollutants
The transport and dispersion of pollutants, within and from a large urban area, are important processes due to their potential environmental impact on city inhabitants and those living in nearby communities. The release of atmospheric Tracers is a powerful technique to simulate the dispersion of pollutants and to enable direct measurement of the transport path and concentrations along the trajectory. Successful Tracers are inert, non-toxic, non-depositing, with low atmospheric background concentrations, long atmospheric lifetimes, and limited commercial use. This research project is developing the Tracer technology necessary to characterise atmospheric dispersion within the urban environment.
Bristol University is exploiting the many years of experience in Tracer technology coupled with recent advances in gas chromatography/mass spectrometry techniques. There are several components to developing an effective experimental Tracer technology and this project is addressing each of these in turn:
April 1998 - three years
University of Bristol
University of Cambridge
This project will provide the database for testing and developing air quality models.
Industry in general
Other consortia studying urban pollution problems
