Metallic species In ambient air particles. PM10

Abstract

En el presente trabajo se cuantificaron las especies metálicas del material particulado (PM10) presente en un área urbana de la isla de Gran Canaria. Las medidas experimentales fueron realizadas desde octubre de 2004 a septiembre de 2005 con un total de 53 muestras (4 o 5 por mes). La PM10 se recogió en filtros de fibra de vidrio utilizando muestreadores de alto volumen. La concentración promedio fue de 32,6 ± 19,6 μg/m3. La PM10 se determinó gravimétricamente. Las concentraciones de elementos metálicos fueron analizadas por espectrofotometría de emisión atómica utilizando un ICP-OES. Se encontraron dos categorías de elementos: “escasos” y “abundantes”. Los elementos examinados fueron caracterizados según su origen en emisiones naturales o antropogénicas en base a factores de enriquecimiento. El análisis factorial de la composición elemental se utilizó también para identificar diferentes tipos de fuentes de contaminación posibles.

In the present work metallic species of particulate matter (PM10) present in an urban area of Gran Canaria Island were quantified. Experimental measurements were carried out from October 2004 to September 2005 with a total of 53 samples (4 or 5 per month). PM10 was collected in fiber filters using high volume samplers. The average concentration was 32,6 +/- 19,6 mu g/m(3). PM10 was determined gravimetrically. Concentrations of metallic elements were analized by atomic emission spectrophotometry using an ICP-OES. Two categories of elements were found: "abundant" and "scarce". The examined elements were characterized according to their origin from natural or anthropogenic emissions on the basis of enrichment factors. Factor analysis of elemental composition pattern was also used to identify possible pollution source-types.
