Soil samples were collected from paddy growing site exposed to effluents , paddy growing site without exposure to effluents , fallow land without exposure to effluents ( and fallow-1-1-1 land exposed to effluents (FEE). Fallow fields with effluents release (FEE) were high in Cu (7.8 mg kg), Zn (15.5 mg kg), Pb (87.8 mg kg) and-1 Cd (1.8 mg kg) in comparison to paddy cultivated fields. The chemical and biological soil quality index and relative soil quality index shows that is having better chemical soil quality index
