The use of metals for human benefit started more than 6000 years ago. Their harmful effects were noted much later, with the growing consciousness about environmental hazards. The different industrial processes and other adjuncts of industrial revolution have added considerably to the quantities of such metal occurring under natural conditions. An appreciable proportion enters into the formation of aerosols, known to be toxic to living systems. Assessment of the hazards posed by metal effluents and their mode of action are therefore gaining considerable importance as a part of environment protection.
