Abstrakt:	The article discusses the study on geochemistry of mercury in sediments of a sub-tropical coastal lagoon in Sepetiba Bay, Southeastern Brazil. The sheltered coastal areas have been acting as final receptors of industrial and urban effluents in most developing countries. According to the authors, knowing the total concentration of heavy metals in coastal sediments is not enough to determine the potential contamination in the area. The author stressed that the potential availability of heavy metals in such environments depends on the strength of the binding with sedimentary phases.
