| contents | Comparative study of elemental contents in atmospheric aerosols from three sites in Mexico City using PME Javier Miranda Rosario Paredes Gutiérrez Alejandra López Suárez Antonio González Eduardo Andrade Ciencias de la Tierra A study of the elemental concentrations found in samples of atmospheric aerosols from three sites in theMexico City Metropolitan Area is presented. The samples were collected during the Winter and Springof 1994 using Stacking Filter Units (SFU), devised to separate particles with sizes between 2.5 pm and15 pm (coarse fraction) and smaller than 2.5 pm (fine fraction). Elemental analyses were performedusing Particle induced X-ray Einission (PIXE), which allowed simultaneous detection of 14 elementsheavier than Al. By means of analysis of variance, comparisons among the elemental contents in thethree sites are giveii for both fractions, showing that, although variations are observed for some elements,in tlie fine fraction no defiiiite patteni is found witli respect to the site. On the other hand, in thecoarse fraction the soil-derived elemeiits Si, K, Ca, Ti, and Fe are the inost important contributors tototal mass. 1997 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37013204 en http://www.redalyc.org/revista.oa?id=370 Revista Internacional de Contaminación Ambiental application/pdf Universidad Nacional Autónoma de México Revista Internacional de Contaminación Ambiental (México) Num.2 Vol.13 |
