USING G.I.S. TOOLS TO DEVELOP SPATIALIZED EMISSION INVENTORIES, DATABASE AND MAPS OF ATMOSPHERIC POLLUTANTS OVER THE FRENCH NORTH REGION.

摘要

Development of atmospheric pollutants emission inventory is a critical step with regard to management of air quality at regional scale. The quality of input da tabases (socio economic, transport, industry ...) and the time and space scales specify the inventory effectiveness. But quality often related to a large number of data that classical methodologies can hardly resolve. A specific methodology adapted to air quality model calculation have been developed. The tools used are PostgreSQL as DataBase which is the kernel of the software, the Geographic Information System (GIS) used is GRASS, finally the user interface is a web site using PHP within the PRADO framewor k, all are free softwares. The web site named POQAIR, was settled to provide emission maps and matrixes with various spatial and temporal scales. The inventory concerns a large range of pollutants such as SO2, NOx, NMVOC, CO2, CO, CH4, NH3, N2O, HCl, HF, Pb, Zn, Cd, Hg, dioxins (PCDDs) and Total Suspended Particles (TSP).
