Abstract

This technical research mainly focused on heavy metal mobility in the soil environment. Once metals are introduced to environment and contaminate, the metals will remain for longer duration. Metals do not degrade like carbon based molecules. However, in general it is very difficult to eliminate metals from the environment. Heavy metal pollution problem arise when the heavy metals are mobilized into the soil and absorb by the plants or transported to the ground water. In this research the mobility of heavy metals has been identified by adopting speciation technique in surface and sub-surface soil of industrial area of Mysore, India. In the surface soil the concentration of the heavy metals are low when compare to the sub surface soil. This type of behaviour was due the influence of the pH, organic matter, electrical conductivity, retention time, leachability and microbes present in the soil. In the speciation analysis the mobility of the metals was estimated from surface to sub surface region. When compare to the total metal concentration in the surface soil it was observed that 90% of the metal concentration were moved to the sub surface soil. Finally the residual fraction has higher level of concentration of metal indicates no much movement and in the remaining fraction has lower level of concentration revealed that the mobility and the toxicity is very high.
