- Characterization of atmospheric particles: analysis of particles in the Campo de Gibraltar A. Umbría M. Galán R. Martín M. J. Muñoz Biología south Particulate matter western Mediterranean anthropogenic and natural sources morphological and chemical analysis Campo de Gibraltar is a highly industrialized area situated in the South of Spain around Algeciras bay (36° 7N,5°27W). This area has an advantageous situation from a geographical, geological and botanical points ofview. However, high wind speeds and a substantial degree of turbulence characterize this area, a situationthat contributes to the rapid and wide dispersion of atmospheric pollutants and natural particles that areemitted in the atmosphere. The work described here involved the use of scanning electron microscopy (SEM)and X-ray Dispersive Energy Spectrometry (EDX) to characterize the atmospheric particles (both natural andanthropogenic). The electron microscopy method provides, simultaneously, knowledge about the morphologyand the chemical composition of the particles. These are the fundamental parameters that need to beinvestigated to determine the origin of the particles. A systematic method has been developed that is applicableto the study of particles collected in emission sources, as well as to particles collected in inmission stations.This simple method allows the origin of the particles to be determined. Finally, a general classification ofparticles has been devised in terms of their physical and chemical characteristics, including morphology,surface characteristics and elementary composition. 2004 artículo científico 0187-6236 https://www.redalyc.org/articulo.oa?id=56517401 en http://www.redalyc.org/revista.oa?id=565 Atmósfera application/pdf Universidad Nacional Autónoma de México Atmósfera (México) Num.4 Vol.17
