Abstract

ABSTRACT


 Soil samples were collected from fifteen different localities situated near coal based Kota Super Thermal Power Plant Station (KSTPS) in Kota City, India in summer season of 2019 - 20. Assessment of the soil samples was done to measure physico-chemical properties, total heavy metal concentration and chemical speciation of the heavy metals as a function of soil properties. The lability of heavy metals such as Ca, Fe, Cu, Cd, Pb and Zn in soils was measured by sequential chemical extraction procedure (SCE) to separate the metals into water soluble, MgCl2, NH4-acetate, hydroxylamine hydrochloride, HNO3/H2O2 and HF/ HNO3 extractable fractions. Ca and Fe associated with HF/ HNO3 and Na-acetate extracted fractions, copper with Fe-Mn oxide and HF/ HNO3 extracted fractions, Cd with HF/ HNO3 and hydroxylamine hydrochloride extracted fractions, Pb with organic and Fe-Mn oxide bound extracted fraction & Zn with hydroxylamine hydrochloride and carbonate extracted fractions. The metals bound with hydroxylamine hydrochloride and HNO3/H2O2 extractable fractions may be available to the plant and animals according to the pH and other physico-chemical properties of the soil.
