Development in sciences are influenced by the wys of comfort in living today. But, the development has provided high problems such as environmental pollution. Heavy metals are the most important elements that contaminated environment and are poisonous for human as well. These elements such as Pb, Zn, Cr, Cd, Co and Cu are produced by industrial activities.
This paper attempts to apply geochemical methods such as statistical and geostatistical method for evaluation of distribution heavy metals in soils. Thermal power plant of Shazand in the close of Mohajaran of Arak city is the center of elemental pollution accompanied with refinery and petrochemical in this area.
This study is determined that among the elements such as Pb, Zn, Cr, Cd, Co and Cu, only Cd is contaminants element.
The amount of Cd is high in fuel raw of Iran and Shazand power plant uses this fuel. Therefore, Cd has increased in the extruded smok and has transferred by wind and has deposited in the soil.
