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 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...
