Abstract:

The epiphyte plant Tillandsia capillaris was used as a passive biomonitor to study the relationship between elemental accumulation and emission sources in the province of Córdoba, Argentina. The concentrations of As, Ba, Br, Ca, Ce, Co, Cr, Cs, Eu, Fe, Gd, Hf, K, La, Lu, Na, Nd, Rb, Sb, Sc, Se, Sm, Ta, Tb, Th, U, Yb, and Zn were determined in T. capillaris leaves by Instrumental Neutron Activation Analysis. A variogram analysis was performed to identify the emission sources of these elements in the study area, obtaining different patterns for each element analysed. A principal-component analysis was subsequently performed to further confirm the different contaminant emission sources and it coincided with the results of the variogram analysis. We observed that the enrichment of most elements was associated with natural sources (soil) and that only some elements showed evidence of enrichement related to sources such as traffic (K, Sb and Zn), industries (Br), and mining activity (Ca). © 2008 Taylor & Francis.
