The littoral macroalga Enteromorpha prolifera was sampled along the Scheldt estuary at Lillo (Belgium), Bath and Ellewoutsdijk (SW Netherlands). The algae were incubated in water from the same locations with salinities of 7, 14 and 23%, at about 50 µmolquanta m-2 s-1 irradiance and 15 °C. One series of cultures was exposed to 400 nm Cd, a second series served as a control. Temporal changes in cadmium, copper, iron, lead and zinc contents of E. prolifera were monitored with atomic absorption spectroscopy in a 21 day experiment. Both synergistic and antagonistic metal interactions became evident in response to cadmium uptake. During the first 8 days of incubation iron contents increased in both cadmium-exposed and control algae. However, iron contents were relatively higher in cadmium-exposed algae. Similar, but weaker synergisms were also found between lead/cadmium and coper/cadmium. Zinc contents decreased in controls and cadmium-exposed algae, but were significantly lower in cadmium-exposed algae. A distinct antagonism between cadmium and zinc was observed in cadmium-exposed algae.
