In this study, physicochemical characterization of Atmospheric Particulate Matter (PM) was performed in an urban-industrial site background (Bailén, Southern Spain), highly influenced by the impact of emission plumes from ceramic factories. This area is considered one of the towns with the highest PM10 levels and average SO2 concentration in Spain. A three stages methodology was used: 1) Real-time measurements of levels of PM10 and gaseous pollutants, and sampling of PM; 2) Chemical characterization using ICP-MS, ICP-OES, CI and TOT, and source apportionment analysis (receptor modeling) of PM; and 3) Chemical characterization of emission plumes derived from representative factories. High ambient air concentrations were found for most major components and trace elements compared with other industrialized towns in Spain. V and Ni are considered fingerprints of PM derived from the emissions of brick factories in this area, and were shown to be of particular interest. This highlights the high V and Ni concentrations in PM10 (122 ngV/m3 and 23.4 ngNi/m3), with Ni exceeding the 2013 annual target value for the European directive 2004/107/EC (20 ng/m3). The methodology of this work can be used by Government departments responsible for Environment and Epidemiology in planning control strategies for improving air quality.
