Diagnosis of TOC Concentration and Deposition in Bottom Sediments and Comparison with Urbanization Indices

This study aims to apply calculations and methodologies for the evaluation of concentrations of Carbon Organic, zinc and nickel coupled to the local reference values (background). This resolution set the general guidelines and minimum procedures for the evaluation of the material to be dredged in Brazilian jurisdictional waters. These goals are achievable through sampling in sedimentary profiles (Core Sampling) deposited over the years on the Mãe d'Água reservoir. The obtained results show that the concentrations of zinc and nickel in the samples were above the local background value with growth and enrichment patterns. Keywords - Sediments. Sediment quality. Mãe d’ Água reservoir.
