Abstract

The Lower Rio Grande Valley (LRGV) has shown a dramatic increase in population, commerce, and traffic activities in the last decades. Results of the application of a GIS/Source Modeling approach to evaluate the possible contributions of different US and Mexican sources on PM10 transboundary concentrations in the LRGV were presented. Emission maps were created for PM2.5, VOC, CO, SOx, etc., for fixed, mobile (on-road and off-road), area, and natural sources. PM10 emissions from area sources had the highest contribution in PM10 concentrations in the LRGV. The emission inventories would improve the quality of the results when they allow to gain greater knowledge about the location of the sources and the quantities of the different pollutants emitted by each source. The impact of transboundary pollution happened mainly towards the south and southeast; the Mexican urban zones are the most affected. This is an abstract of a paper presented at the AWMA's 99th Annual Conference and Exhibition (New Orleans, LA 6/20-23/2006).
