Abstract Investigations have been conducted with a green alga, Scenedesmus acuminatus, into the relationship between the amount and rate of copper accumulation, reduction in growth and changes in K+, Mg++, Na+ and Ca++ during copper uptake. In light, aerated conditions the presence of calcium (10 μM) in the treatment medium decreased the rate of copper uptake and exchange of potassium, magnesium and sodium, and increased the concentration of intracellular copper required to inhibit growth.
