摘要: Abstract Temporal and spatial variability in metal concentrations (Zn, Cr, Cd Fe) soft tissues of the oyster C. brasiliana from Sepetiba Bay Ribeira were determined for three different periods.Significant spacial differences observed Zn but no temporal variations detected. High correlation factors between found as well. The proved to be a good ecological indicator monitoring programs.
