Description :
The forecast climatic warming will cause hydrological changes on Earth which will be accompanied by changes to the chemism and quality of waters. On account of their wide-spread occurrence and permanence, it is heavy metals in the bottom sediments of surface waters which pose the greatest endangering to the natural environment. Once introduced into it, they cannot be removed, and can in suitable conditions be released from bottom sediments and give rise to secondary pollution of waters in their soluble forms. For this reason, heavy metals have been termed chemical time bombs.
