Abstract: | The study area is highly industrialized, with businesses involved in the non-metal mineral products sector and ceramic industries
(colors, frits and enamel manufacturing) standing out. Air quality evaluation was performed regarding atmospheric particles
(PM10 fraction) and Pb in a Spanish coastal area during 2001 and 2002 in order to compare these values with other areas in
the Mediterranean basin. Once the samples were collected, their PM10 fraction concentration levels were determined gravimetrically.
A Pb analysis in air pollution filters was carried out by ICP-MS. The seasonal and weekly variabilities of these contaminants
were also studied, with the objective of being able to explain their origin and thus minimize their possible damaging effects.
A similar evolution of PM10 and Pb was observed in both years of the study. Higher PM10 concentrations have been detected
during the months of June and July, lower values between March–May, August and October–December, and intermediate values in
January and February. A similar tendency has been observed by other authors in European industrialized cities. Regarding Pb,
the monthly mean remains constant during the entire year. In the study area, Pb represents 0.6% as a mean of the total PM10
mass, with a variation range between 0.1 and 5.1%. The major crystalline phases in PM10 were quartz, calcite, dolomite, illite,
kaolinite and feldspars. |
