Abstract
Cadmium and chromium interactions with aquatic humic substances from p ampasic ponds (Argentina) were studied by gel permeation chromatograph y. Separations of humic-metal complexes and free ions were performed v ia Sephadex G-15 and elution curves were analized. It was observed tha t Cr and Cd (usual pollutants in argentine environments) form complexe s with humic substances which may affect their toxicity. The photo-sta bility of the complexes was also taken into account.
