Abstract

Generally heavy metals exist in all soils, but soil pollution is rising by time due to human activities. Soils in the proximity of mines are more pruning to pollution of heavy metals due to mine exploring and excavation. This research was carried out to evaluate the soil pollution of Sepahanshahr Suburb with Pb, Zn and Cd. During a field work campaign 100 soil samples were selected randomly from 9000 ha area. The soil samples were treated with 4 M HNO3. Total amounts of Pb, Zn and Cd were measured using Atomic Absorption Spectrometer. The results indicated that concentration of Pb and Zn were beyond the defined soil pollution thresholds (
