Survey of Lead and Zink Pollution in Surface Soils around the Shokouhieh Industrial Estate

In this research, the amount of soil contamination in Shokhoyeh industrial city of Qom province was determined to lead and zinc metals. Using random sampling method, samples of 10 stations in 5 km distance of Shomkhoyeyeh industrial city of Qom were prepared and lead and zinc concentrations were determined by atomic absorption spectroscopy. Using ArcGIS, the lead-zinc zoning was determined. The mean concentration of lead and zinc in the soil between the stations that were sampled in the study area was 13.03 and 811.0 mg/kg, respectively. The results showed that, at station 1, the mean concentration of zinc is 60.1 and lead is 98 mg / kg and more than standard, except for station 1, lead and zinc levels at other stations were lower than the standard.  The reason for this phenomenon can be near the main road (Qom-Tehran). According to the distribution map of lead concentration in surface soil, the highest concentration of lead in the study area is in the range of 1.50 to 100 mg / kg. In the southwest industrial town and bypassing this section, surface contamination decreases with lead. The highest zinc concentration in the studied area was in the range of 7.00 - 9 mg/kg. In the southwest of Shokoieh industrial city of Qom and Bypassing this section, soil contamination decreases with zinc.
