Abstract

Eighteen metallic elements were analyzed in dry deposit samples bymeans of X-ray fluorescence, atomic absorption spectrometry and plasma emissionspectrometry. Samples were obtained in 10 monitoring stations, covering Northeast,Northwest, Center, Southeast and Southwest areas of the Metropolitan Zoneof Mexico Valley (MZMV). The collection periods were two months during endsummer and autumn seasons in 1999 using an automatic sampler, placed at one-meterheight. Metallic element concentrations and the enrichment factors allowedus to classify elements having a common source: anthopogenic, like Pb, Zn,Cu , etc, natural (soil derived elements), like K, Ca, etc. Some correlationwas established between the obtained results and parameters such as the samplingplace, season, wind direction and soil composition in a single area.
