Abstract

Heavy metals pollution is one of the main drawbacks of using wastewater for irrigation. Exploring the pollution of heavy metals in a vast area needs frequent experimental measurements, which is mostly time and money consuming. In this study, the image of Sentinell2 satellite was used to evaluate the heavy metals pollution of wastewater irrigated area in south of Tehran, IRAN. For this aim, 30 soil-surface samples were collected from the study area and the concentrations of Pb, Cu and Ni were determined using atomic absorption spectroscopy. Then the relation between the heavy Metals concentrations and Reflectance in the Bands or the ratio of the Bands at the corresponded sampling points was determined by applying the stepwise regression method. The developed models were applied on the Satellite image for Zoning the heavy Metals concentrations in the study area. Finally, the accuracy of the developed models was examined by Root-Mean-Square Error (RMSE) and Pearson correlation coefficients. The results showed that the amounts of RMSE for the equations of Pb, Cu and Ni were 1. 90, 2. 54 and 1. 59 ppm respectively while the amounts of R were 0. 81, 0. 75 and 0. 73 for these metals that showed a promising match between estimated and measured results.
