The purpose of the present study was to evaluate and zoning the environmental hazards of heavy metals in the soil using the Nemerow integrated pollution index in vineyards (vineyards) of Malayer city. In this study, after consecutive visits to the study area and reviewing the map of the area, sampling operations were performed in January 2019. Soil sampling was performed based on a systematic random method. A total of 286 samples were collected from topsoil (depth 0 to 20 cm). Of these, 157 samples were located in agricultural lands (gardens and agricultural land) and 129 samples in natural areas (pastures and barren lands). The samples were analyzed by high-resolution continuum source atomic absorption spectrometry (HR-CS AAS) and using the fame method. The average concentrations of Cu, Mn, Zn, Cr, As, Ni and Hg are 87.86, 597, 109, 67.12, 47.1, 84.32, and 0.344 mg/kg, respectively. These values are lower than the NIPI index values for these metals. The results showed that there is a positive and signifcant correlation between Cu and Mn, Cu and zinc, Cu, and As as well as As and Ni. There is also a signifcant negative correlation between Cu and Hg, As and the electrical conductivity (EC) as well as As and Mn. At present, these soils are not at serious risk of soil contamination with heavy metals.
