A geographical tool for personal exposure assessment.
Résumé
The European policy in urban atmospheric pollution aims at reducing its impact on human health. This particular problem of public health is closely related to the daily exposure of the population. Its estimation through analysis of individuals activities defines the space-time budget. Sooner or later the local authorities in charge of air quality will have the duty to provide to the population their collective or individual exposure. We have developed here a tool that supplies this information. It is based on a multi-source approach. It exploits a Geographic Information System (GIS) gathering information such as individuals mobility, the topographic database, and concentrations of pollutants. Maps and dynamic representations of individual exposure are obtained. They display indoor (home, place of work) and outdoor exposure.
