Abstract
Soil heavy metal study is carried out in Bolani and surrounding areas to assess the soil contamination levels with respect to heavy metal loads. Sampling of soils is carried out in post-monsoon and pre-monsoon periods. Heavy metals were determined by Atomic Absorption Spectrophotometer. The heavy metal concentrations determined are Fe, Mn, Co, Zn, Ni, Cd, Pb, Cr and Cu. Value for Fe range from 5.03 to 48.03%, Mn range from 0.065 to 0.483 %, Cd varies from 2 to 120 µg/g, Co value range from 53 to 160 µg/g, Cu varies from48 to 100µg/g, Ni varies from 38 to 105µg/g, Pb range from 15 to 25 µg/g, Zn varies from 55 to 230µg/g in pre monsoon period. The post monsoon heavy metals concentrations show higher values in comparison to pre monsoon period. Remedial steps may be taken to prevent soil contamination from mining in rainy season.
