The effect of copper sulphate as an algicide is reviewed briefly. In experiments in which Anabaena flos-aquae and Scenedesmus quadricauda were exposed to different concns. of the chemical A. flos-aquae was more sensitive and accumulated more copper than S. quadricauda. The lethal concentration of accumulated copper was similar for both species. The sensitivity of A. flos-aquae decreased as the alga aged. The implications of these results for the use of copper-based algicides are discussed. From summary.
