Evaluation of environmental contamination and pollution at the area under the influence of the Morro do Céu landfill dump in Niterói, Rio de Janeiro, Brazil



Evaluation of environmental contamination and pollution at the area under the influence of the Morro do Céu landfill dump in Niterói, Rio de Janeiro, Brazil



Cadernos de Saude Publica 12(4): 515-523



In general, areas used for waste disposal represent potential foci of environmental pollution, as they can contaminate the surrounding environment and negatively impact the health of the populations living nearby. This study reports on results obtained in the analysis of Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn in the leachate and other environmental compartments (ground and subsoil waters, soil, and sediments) of an area under the influence of the Morro do Céu Landfill Dump, located in Niterói, Rio de Janeiro State, Brazil. Quality of water compartments in the area was evaluated using other physical/chemical and microbiological complementary parameters such as COD, BOD, pH, colimetry, etc. Results showed that most of the metals are retained by the soil and sediments. The local waters (surface and subsoil) are contaminated by coliform, while the surface water, the Mata-Paca River, showed high levels of COD (5.200 mg/l), BOD (2.800 mg/l), Fe (6.4 mg/l), Mn (2.4 mg/l), Ni (0.12 mg/l), and Zn (0.23 mg/l).
