The presence of heavy metals and nuclear
wastes have raised the level of toxicity in our
environment. The dissolved humic substances complicate the
migration process of metal pollutants. Humic substances may
mask the surfaces of the minerals for reaction with
contaminants. Hence, availability and fate of heavy metals
in the soil are strongly dependent on the extend of their
sorption on hydrated phases. The Present study was focused
on the phenomena of retardation of metal migration through
