Studies on Assessment of Heavy Metals in Samples Collected from Surrounding Area of Fly Ash Dumping Ground
Journal Title: Universal Journal of Environmental Research and Technology - Year 2015, Vol 5, Issue 3
Abstract
Coal burning can organize trace elements by presenting them to the surrounding environment. When these elements leached out may cause the contamination of soil, surface water and groundwater. Disposal or any function of coal ash is becoming a major topic because of its potential to pollute surface and groundwater with heavy metals. Potential heavy metal problems with power plant wastes are greatly shortened by the pronounced liming effects of the wastelands. In the present study relative abundance of total heavy metals in fly ash was found in the order As, Cu, Cd, Pb, Hg and Zn. The concentration and availability of metals depends on the character and nature of the coal used in thermal power plant. In the acid digested solution all metals were found above detectable limits. Arsenic, Mercury and Zinc found in greatest extent in soil samples i.e. Hg – 20.51 to21.74 ppm, As – 3.32 to 4.47 ppm Zn – 7.39 to 9.00 ppm. The assessment of the great metal shows that the fly ash dumping ground and surrounding area contains bioavailability of different heavy metals which can well recover, reuse and recycling potential of fly ash.
