Resumo
Soil samples were collected in 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 INAA
to study the spatial distribution. This agricultural area is used for garlic
cultivation. The soil samples and the standards were irradiated in the
swimming pool research reactor at IPEN-CNEN/SP, Brazil. The data sets
were studied using several statistical methods. In order to evaluate the
contribution of anthropogenic sources in the soil, enrichment factors were
calculated. The similarity/dissimilarity between the samples was studied by
discriminant analysis in order to explore the feasibility of classifying soils
samples according to geographic position. In addition, to identify redundant
variable without losing essential information, the data set was studied by
means of stopping rule for variable selection using forward stepwise
discriminant analysis.
