Abstract

In mining areas, assessing toxic elements (e.g., ARSENIC) contamination in the soil and stream deposits is a critical issue. It is because MINING ACTIVITIES release dangerous elements that enter the environment. In this paper, for modeling the spatial distribution of ARSENIC contamination in Sarduiyeh-Baft area, in Kerman Province, across an area of ca. 5000 km2, 1804 stream sediment samples were collected and analyzed. The recommended standard limit for ARSENIC in soil is 20 ppm, so samples showing ARSENIC concentration >20 ppm are contaminated samples, which need land reform processes. However, since the number of collected samples is limited, INDICATOR KRIGING method was used to identify the possibility of contamination. In the study area, there are 32 known occurrences of PORPHYRY-CU deposits. Thus, in order to estimate the ARSENIC contamination in the unsampled locations, INDICATOR KRIGING method was used. The results indicate ARSENIC contaminations in north and northwest parts of the study area, which could be occurred by mining of the PORPHYRY-CU deposits. However, the results show that there is no ARSENIC contamination in the eastern part although there are several mining sites with high activities.
