Resumo


This work quantified trace metals concentrations in sediments samples from an urban area (Mangrove Park), using emission spectroscopy. Average values, for chromium, were 83 mg.kg-1,in the rainy season, and 82 mg.kg-1 in the dry season. For manganese the corresponding average values were 154 mg.kg-1 in and 195 mg.kg-1 , and for zinc 255 mg.kg- 1 and 224 mg.kg-1. The concentrations for the three metals are above those we measured for background. We conclude that there is contamination by these metals in the study area. Keywords: Trace metals. Estuaries. Sediments. Urban estuary.
