Summary: At the moment, there are very limited data that describe the current and historic situation of air quality in the City of Buenos Aires. This makes it difficult to develop an air quality monitoring system and to define mitigation measures for zones of high air pollution. This case study tries to develop a solution to the problem that does not rely on historical air pollution data.
It is shown, that air pollution does not depend only on the level of emissions, but also on other urban and meteorological aspects that can increase or decrease contaminant concentrations in the air. The study applies risk indices to perform a air pollution risk assessment for Buenos Aires. These risk indices combine urban topography with meteorological variables as indicators of the atmosphere's capacity to dilute contaminants. Automotive transport is assumed to be the major source of air pollution. The next step of this study will use a dispersion model to incorporate dynamics to the indices.
The indices provide a basis for the siting of an air pollution monitoring network and for the interpretation of the collected data They can also work as a tool to evaluate the impacts of traffic variation and new proposals for urban planning on air quality.
The main objectives of this case study are to develop a tool
for urban planning that focusses on air quality issues, and to use this
design an air quality monitoring network.
