Abstract

Industrial activity may result in the accumulation of heavy metals in soils and increase the uptake of these metals by plants. This research was conducted to evaluate the map of soil contamination with Pb and Ni around the Isfahan Steel plant and MOBARAKEH STEEL COMPLEX, as the major industrial area of the Isfahan province. In this research, 208 soil samples were collected in a regularly spaced grid pattern with an interval of 4 km. The sampling distance was decreased to a minimum of 500 m as the sampling point got closer to the industrial plants. The plant available Pb and Ni concentration were determined using DTPA extracting solution. The results showed that the concentration of Pb increased around the Isfahan Steel plant and Ni around two factories. Variograms were best fitted by the spherical model. To determine the estimation accuracy, mean error (ME), mean of sum of square error (MSE) were calculated. The result of validation revealed that high accuracy of estimation for all of the heavy metals especially for Ni.
