Heavy Metals Status in Soils of Ballari District using Atomic Absorption Spectroscopy (AAS)

摘要

Current study reveals that, heavy metals statusof agriculture soils of Sandurtalluk, Ballari district, Karnataka, India. Composite soil samples were collected about 100 m~2 apart at 0-30 cm (top soil) and 50-60 cm (subsoil) depths from study area during the dry season in January, 2016. The soils were analyzed for pH and total concentration of heavy metals such as Cd, Cr, Cu, Fe, Mn, & Zn by using Atomic Absorptio n Spectrometer (AAS) Technique. Results show that total mean concentrations of the heavy metals decreased with depth. Whereas, the mean concentrations of the metals in the top and sub soil of Sandur mine increased respectively in the order, Fe > Zn > Cu > Mn > Cd > Cr.
