Analysis of Heavy Metals in Pond Ash Samples from Haryana
This study reports the heavy metal content of three thermal power plant pond ashes from inflow and outflow
point. Heavy metal analyses of these ashes were studied by standard leaching tests, namely TCLP-1311 procedure. The ashes
were analyzed for the presence of Co, Mn, Zn, Cu, Ni, Pb, and Cr and detectable levels were found in all pond ash samples.
In the current study, the concentration of Ni, Pb, and Cr elements are the quite higher side in all ash samples than the limit
value of the inert material, but lower concentration than the limit values of non-hazardous materials for waste acceptance
criteria and satisfying the landfill regulation criteria.
