Identification of atmospheric trace-element sources by passive biomonitoring employing PCA and variogram analysis

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,...
