The dynamics of algal copper uptake from media containing various copper concentrations was studied. A direct relationship was found between the copper accumulation by the cells and algicidal action of a given compound. The high biocidal activity of copper complexes is due to the ability of the cells to take up large quantities of copper from compounds with a coordination bond between the metal and the ligand. Toxic (0.78 x 10/sup -5/ to 7.8 x 10/sup -5/ M) concentrations of copper complexes disturb salt metabolism in algal cells due to copper accumulation or potassium loss. If the concentration of a copper compound with a coordination bond is 7.8 x 10/sup -5/ M, the content of potassium in the algal cells decreases by 80% within 30 to 60 min.
