Abstract

Monitoring and model calculations of automotive exhaust-related air pollution in an Amsterdam urban street canyon H. Heida, A.L. de Jong OMEGAM, Environmental Research Institute, City of Amsterdam, PO Box 94685, 1090 GR Amsterdam, Holland SUMMARY As a follow-up of a random air sampling program aimed at determining the effect of automotive exhaust emissions on ambient air quality in a number of urban street canyons In Amsterdam, a continuous monitoring program was conducted at a single sampling site in a typical downtown street canyon during 1987-1989. Monitorings were made for CO, NO, NO,, SO, and O,. The objective was to elucidate air pollution build-up as a result of air temperature, solar radiation, wind speed and wind direction. Furthermore, the monitoring program offered an opportunity to test and calibrate the officially adopted CAR street-air pollutant dispersion model, as well as the APRAC-1A model applied in SL Louis-USA street canyons.
