Abstract
This study focuses on the determination of trace element concentrations in total suspended particles by instrumental neutron activation analysis (INAA) in two different areas in Northeastern Spain (a rural area influenced by the emissions of a large coal-fired power station, and the urban and industrial areas of Castellón). Total suspended particles were sampled by means of standard MCV high- and medium-volume captors, using cellulose membrane filters of 0.8 and 0.45 μm pore size. Preliminary research was performed on the homogeneous distribution of elements in the sample filters and on the study of blank filters for the calculations of the background average element contents. The results obtained allowed to distinguish different major anthropogenic sources of trace elements in the atmosphere at the sampling sites: a) Zr, Hf, Sc, U and Th are related to atmospheric pollution derived from the ceramic industry of the Castellón area; b) As, Cr, Cs, Rb, Sb, Se, Zn are related to traffic and other industrial emission in the Castellón area, and As, Cr, Sb and Zn to power generation emissions in the rural area.
