Abstract
Different areas from the Todos os Santos Bay were monitored and the fate of heavy metals in these environments was determined. From 1982 to 1992, a significant worsening in the availability of heavy metals in the different sites of the Bay was observed. However, it must be emphasised that the comparison between the present results and those obtained from other works rests on a gap of at least three years. The determinations of heavy metal concentrations were based on the analysis of surface sediments of the different stations selected and the observed increase is probably due to the transport of the elements by tidal dynamics and upstream riverine transport of industrial effluents.
