Abstract

The purpose of this study was to investigate the concentration of heavy metals resulting from the deposition of contaminant particles in the surrounding soil and to compare the concentration of heavy metals in the soil with the permissible limits for agricultural use of lands in the surrounding of Shahid Mohammad Montazeri power plant in Isfahan. it was first divided into regular grids (67 grids) based on the grid method and soil sampling was performed in each grid. To measure the physical and chemical properties of soil, 12 samples were selected and 50 samples were selected from 67 samples to measure the concentration of heavy metals. The results showed that soils have an average organic matter content below 1%, which is low and thus the soil is poor. The mean concentrations heavy metals but the concentration of Cd was above the critical level and its concentration was contaminating in the soils.Generally, soil around the plant has no limitations for agriculture in terms of electrical conductivity, pH and concentration of heavy metals except cadmium. It should be noted that due to the transfer and toxicity of cadmium metal, cultivation of industrial plants such as cotton and fruit trees is recommended.
