Abstract

The present study aims to evaluate the Santos harbor environmental health, the most important port of the South American, where anthropic activities are associated to metallic contamination (Al, Cr, Fe, Co, Ni, Cu, Zn, Cd and Pb). Enrichment factor, geo-accumulation index and geochemistry mobility were applied. The results showed increases in the levels of the metals with indicative of moderately to extremely pollution between the estuary and industrial park. The environment risk can become potentially high due to the transfer of metals to species of the trophic net.
