Resumen:
Total zooplankton samples from Argentinian and Uruguayan Coastal Waters were analysed to determine their heavy metal contents. Zinc, copper, cadmium, iron, lead and manganese concentrations were measured using atomic absorption spectrophotometry and metal content distributions were geographically plotted. Except for cadmium, ali the studied metals showed maximum values on the Uruguayan shores, and this was related not only to the location of the potential metal sources, but also to the hydrographical characteristics of the area. Finally, thesuitability of zooplankton as an adequate biological indicator of heavy metal pollution in coastal environments is discussed.
