Includes bibliographical references (pages 24-26). "The technology outlined in this review allows one to analyze, by electron-optical visual means, the flocculation of dissolved organic carbon at a resolution of 0.001 um. As a consequence, the factors which control flocculation in surface waters (pH, concentration factor, hardness turbulence, surface activity, organo-mineral associations) can now beanalyzed in greater depth than previously was possible. The scavenging by colloidal particles of contaminants and subsequent sedimentation of colloid flocs are important phenomena in the dispersion of contaminants in lake waters. This review presents new technology for assessing such phenomena, and analyzing the mechanism"--Management perspective.
