Barite mineralization and mining can be a significant source of potentially toxic elements (PTEs) pollution in soils due to the presence of sulfide minerals. This study deals with the evaluation of soil pollutions and health risk assessment caused by barite mineralization and mining in the mining site of the Kuh-e-Marghavol, located in the east of Mahabad. Samples of topsoils (sampling depth 0-5 cm) from mining and agricultural areas were taken separately. Soil sampling in the mining area (7 samples were taken) was done systematically perpendicular to the main barite vein. Soil samples of central parts of agricultural areas (6 samples) were collected from the mining area's downstream. To determine the PTEs concentration, inductively-coupled plasma mass spectrometry (ICP-MS) was employed. The samples were digested using the four-acid method, which includes hydrofluoric acid, perchloric acid, nitric acid, and hydrochloric acid. In the examined samples, the concentrations of the majority of PTEs exceeded the corresponding values in the worldwide soil average and continental crust composition. Soils from mining site have a very high enrichment factor for As, a significant enrichment factor for Cu and Ba, and moderate enrichment for Cd and Mn. Agricultural soils have a significant enrichment factor for As and moderate enrichment for Mo. According to the individual environmental indices (geoaccumulation index, pollution factor, Nemerow index) the studied soil samples (mining site and agricultural soils) were polluted with PTEs especially As, Ba, and Cu. All samples exhibit high levels of pollution based on the values of the pollution load index (2
