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.

Mining wastes are one of the most dangerous environmental pollutants which, if not removed, enter the surface and groundwater, causing toxic complexes and potential risks to humans and ecosystems. They create an environment. Because ore makes up a small portion of the total volume of minerals mined, mines will have a lot of waste. In the metal industry, the production of copper, lead and zinc cause the most damage to the environment. Copper Mining Operations Generate Extensive Mineral Waste Melting Zinc and Lead Introduces large amounts of cadmium and lead into the environment. The growth of gases and particulate matter, the production of polluted effluents and solid waste are the result of melting and refining metals. Soil contamination with heavy metals is a serious problem associated with metal smelting. In order to study the effects of the studied mine on the environment, it is necessary to examine the water, rocks and soil, plants and even their drains and waterways in terms of pollution. Findings of this study show that Bavanat copper mine has a significant effect on the level of pollution in water, soil and plants in the region.
