By exposing three differents soils (Cambisols, Luvisols and Fluvisols) with neat agricultural vocation, to the contamination of five metals (Cr, Cu, Ni, Pb and Zn) it has been observed that the response to transversal motion of contaminants is very similar in Cambisols and Luvisols, but fully different in Fluvisols. We have used Lyximetry as the evaluation technique , and the square of the euclidean difference of concentrations, as the evaluation criterion. Differences only appear in the case of Fluvisol which overcomes in 600 times the analogons behaviour between Cambisol and Luvisol.
When studied by means of autocorrelations, metalic migration through Fluvisol soils shows seasonal variations, with probability > 95%, a feature which cannot be found in the other two soils.
Key words: Heavy metals, seasonal variation, leaching, euclidean distance.
