摘要：

Environmental degradation due to leaching of elements from fly ash is of great concern. Leaching result of Cu, Fe, Mn, Pb and Zn from the high sulphur fly ash collected from captive power plant of Nagaon Paper Mill, Assam is reported. The pH of the leachate is weakly alkaline in nature, ranging from 7.39 to 7.90. Fly ash contains very high concentration of elements in comparison with Gondwana counterpart. However, mobilization of elements from the Nagaon fly ash is very less, and is possibly due to the presence of high unburnt carbon.
