Abstract: HYDROGRAPHIC BASINS.The input of heavy metals concentrations determinated by ICP-AES, in samples of the Cambé river basin, was evaluated by using the Principal Component Analysis.The results distinguishes clearly one site, which is strongly influenced by almost all elements studied.Special attention was given to Pb, because of the presence of one battery industry in this area.Some downstream samples were associated with the same characteristics of this site, showing residual action of contaminants along the basin.Other sites presented influence of soil elements, plus Cr near a tannery industry.This study allowed to distinguish different sites in the upper basin of the Cambé (Londrina-PR-BR), in accordance to elements input.
