Avaliação das concentrações de metais traço nos sedimentos do Parque dos Manguezais, Região Metropolitana do Recife (RMR), Pernambuco, Brasil

Resumen

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.
