Considering the importance of soil and water pollution and their impact on human health and food chain, the present study deals with the role of heavy metals in soil and water in Abdullah Giv area located on Quchan-Neishabour road, Khorasan Razavi province. In this study, 10 samples from water source and 20 samples from surface soils of the region were taken from a depth of 10 to 20 cm and after preparation and analysis were studied in terms of heavy metal concentrations. The results of the study showed that in the waters of the region, the highest concentration is related to Sr and the lowest concentration is related to Cd, but the concentration of all elements is less than the global health standard. The results of the concentration of heavy metals in the soil of the region and its comparison with the standard of the Environmental Protection Organization in alkaline soils showed that the amount of heavy metals Cr and Ni in the soil of the region is more than the standard. The presence of basaltic igneous rocks in the area can play a role in this. Studies show that to the west, the concentration of heavy metals in the region's water and soil resources is increasing.
