Soil samples were colletected from two small agricultural fields located in Médanos and Hilario Ascasubi, Bahía Blanca, Argentina and analyzed for Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Na, Rb, Sc, Th, U, Yb, and Zn by instrumental neutron activation analysis (INAA). In order to evaluate the contribution of anthropogenic sources and the similarity/dissimilarity between the samples, the data-base was studied by means of enrichment factors (EF) and discriminant anlysis (DA), respectively. In addition to identifying redundant variables without losing essential information, the data set was studied using forward stepwise discriminant analysis.
