Cadmium and copper in the dissolved and particulate phase and in zooplankton were determined in the Bahı´a Blanca estuary during six surveys from March to December 2005. Temperature, pH, salinity, dissolved oxygen, suspended particulate matter, particulate organic matter and chlorophyll-a were also considered. Dissolved Cd was below the detection limit (0.2 mg L1) for almost the entire study period whereas Cu concentrations (0.5–2.4 mg L1) indicated a continuous dissolved Cu input. Particulate Cd concentrations ranged from below the detection limit (
