Abstract

Among the various environmental pollutants, heavy metals are the most important due to their non-degradability and physiological effects on living organisms. In this study, in order to investigate the soil contamination around Zobahan and also to evaluate the efficiency of satellite images in estimating the concentration of heavy metals. Soil sampling was performed from a depth of 0-20 cm in a combined manner. Atomic absorption spectrometer was used to measure heavy metals, SPSS 23 software was used for statistical analysis and Landsat 8 satellite OLI sensor images and ArcGIS 10.5 software were used to measure and zoning cadmium and lead in the study area. The results showed that there was a negative correlation between the concentration of lead and visible and infrared bands, but no correlation was observed between the concentration of cadmium and the digital value of the bands. Among the 20 areas studied, the highest amount of lead and cadmium contamination was observed in station 1 located near the steel plant.
