Soils are the major sinks for heavy metals released through broad range of industrial, farming and manufacturing sources. The main objective of the study was to determine the heavy metals based soil quality with respect to different land uses. Soil from different land uses of Sadiqabad city were assessed to determine the concentrations of selected heavy metals (Cr, Co, Ni, Mg, Cd, Cu, Pb& Zn) along with other parameters (P, K, N, pH, EC & MC). The Pearson Correlation test revealed a strongly significant correlation at the (0.01) level in Fluoride. Nickel (0.5 to 1.1µg/g) was within the EPA standard value (82 to 37µg/g). Lead and Fluoride were violating the acceptable ranges of the given standards in all collected soil samples. The contaminants can be transferred to humans through consumption of food grown on contaminated agricultural land or through inhalation of contaminated dust thus, leading to the elevated burden of heavy metals in residents and commuters of the area.
