Resumen:
The objective of this research is the chemical characterization of the PM10 for the winter and summer seasons in the urban and rural zones of Mexicali. The samplings were realized every other day, using low volume samplers with two types of filters, quartz and teflon. The filters were analyzed for total mass by gravimetry, 38 metals (Na to Pb) by X rays spectroscopy analysis, anions (Cl-, NO3 -, SO4 2-) and cations (Na+, K+, NH4 +) by ions chromatography, and organic and elemental carbon by thermal optimal transmittance. During the winter season the Mexican norm which is 120 µg m-3 averaged for 24 hours, was exceeded by 27 times, meanwhile in the summer season the norm was exceeded by 15 times. In the summer season the geological material predominated while in the winter was the organic material the predominant one. It is concluded that the urban zone was the most polluted in the summer and in the rural was more polluted in the winter. © 2014, Centro de Informacion Tecnologica. All rights reserved.
