Resumen:
tThis research work presents new insights regarding biomonitoring studies, source apportionment at alocal scale, and influence of wind and topography on dispersion of atmospheric pollutants in a complexscenario. The monitoring network consisted of transplanted Tillandsia capillaris biomonitors throughout3 sampling periods in order to assess the effects of the different emission sources and their atmosphericdispersions in a region from the province of Córdoba, Argentina. The elements Mn, Fe, Co, Ni, Cu, Zn,Cd and Pb, were analyzed by Flame Atomic Absorption Spectrometry (FAAS, pseudo-total metal con-tent) and As, Ba, Ca, Ce, Cr, Cs, Eu, Fe, Hf, La, Lu, Na, Rb, Sb, Sc, Se, Sm, Ta, Tb, Th, U, Yb and Zn, byNeutron Activation Analysis (NAA, total metal content). The following atmospheric emission sourceswere characterized in the study area: cement plant, with emissions of Cd, Pb, CoFAAS, Ni and Ca; wastedumping site fires, with emissions of the elements Sm, Yb, Ba, La, ZnNAA, Ce, Th and Hf; brick kilnswith emissions of the elements Na, Ba, As, Se, Cr, Tb, Sc, FeNAA, CoNAA, Ta; vehicular traffic with emis-sions of ZnFAASand Sb and soil re-suspension with emissions of Ni, ZnFAAS, Br, U, Mn, Rb and Eu. It wasnoticeable that topography played an important role in the dispersion of the pollutants in the studyarea and this was reflected in the biomonitors. Our results provide a step forward in the applicationfield of this biomonitoring species for characterizing emission sources in a complex scenario at a localscale.
