Tabulated and graphical results are given of experiments showing that the uptake of phosphorus by the green alga Selenastrum capricornutum is related both to time and to the concentrations of sodium and phosphorus in the external medium. In the absence of sodium, external potassium concentrations of up to 110 mg per litre appeared to depress phosphorus uptake. The blue-green alga, Microcystis aeruginosa, was found to be more efficient than Selenastrum in absorbing phosphorus from the medium. The implications of the results as regards eutrophication of surface waters are discussed.
