-
in a less desirable scenario, the contaminant transforms into another
undesirable molecule. The model example is that of the pesticide
atrazine, which remains in the environment as desethyl-atrazine.
-
another still-risky scenario is that of contaminants held stable by
their environment, but likely to be released if there is any change
in physical or chemical conditions. For example, certain heavy
metals can be adsorbed and then desorbed due to a natural or
anthropogenic change in the pH or the Redox Potential of the
water.
