The contribution of heavy metal pollution derived from highway runoff to Guanabara Bay sediments--Rio de Janeiro/Brazil.
In this study, geochemical and particle size analyses of thirty-four street sediment samples collected from an urban environment around Guanabara Bay, shows highway run-off to be a potential source of heavy metals for the pollution of near-shore sedimentary deposits. Concentrations of Fe, Mn, Zn, Cu, Pb, Cr and Ni were found to be higher in these sediments when compared to concentrations found ...
متن کاملTrace Metal Contamination in Mangrove Sediments, Guanabara Bay, Rio de Janeiro, Brazil
A Baía de Guanabara no Rio de Janeiro tem sofrido profundas alterações ambientais. O aumento da concentração de metais-traço em seus sedimentos está entre as alterações mais relevantes. O objetivo deste trabalho foi verificar a contaminação por metais-traço e avaliar a disponibilidade em sedimentos de áreas de manguezais (Surui, Nova Orleans e Piedade). Concentrações de Cd, Zn, Pb, Ni, Cu e Al ...
متن کاملBenthic foraminifera distribution in high polluted sediments from Niterói Harbor (Guanabara Bay), Rio de Janeiro, Brazil.
Dockyards and harbors are recognized as being important locations where sediment-associated pollutants can accumulate, which constitutes an environmental risk to aquatic life due to potential uptake and accumulation of heavy metals in the biota. The aim of this paper is to assess the concentrations and the effects of some heavy metals in the benthic foraminifera assemblage in Niterói Harbor. Lo...
متن کاملGeochronology and heavy metal flux to Guanabara Bay, Rio de Janeiro state: a preliminary study.
Guanabara Bay, located in Rio de Janeiro state. It is surrounded by the second most important metropolitan area of the country. Over recent decades, land disturbance and urbanization in the surrounding area has significantly increased sediment input to the bay and had a negative effect on its overall environmental. This is especially related to high volumes of untreated sewage and industrial ef...
متن کاملMetal Distribution in Sediments from the Ribeira Bay, Rio de Janeiro – Brazil
O estudo de metais em áreas preservadas assume grande relevância devido à falta de níveis de base para comparação com estudos em áreas impactadas. Para 23 amostras de sedimento de superfície da Baía da Ribeira, RJ, foram determinadas por ICP/AES as concentrações de Ti, Ca, Mg, Fe, Al, Sr, La, V, Y, Ni, Cu, Cr, Mn e Zn. Hg foi determinado por CVAAS. Utilizando Al como referência, os metais foram...
