Abstract: In this study we analyzed and estimated heavy metal accumulation in hundri river sludge and control (normal fertile soil) quantitatively along with their physical and chemical properties (pH, Temperature, Moisture content, Organic carbon, Nitrogen, Phosphorus and Potassium). Results showed that river sludge shows high pH, low temperature, high organic and NPK than control soils. Our study found eight heavy metal components namely Ag, Co, Cu, Cr, Ni, Cd, Zn, and Pb) in both river sludge and control soil. However river sludge showed high amount of all eight heavy metal accumulation than control soils when compared with toxic level standards. Detailed results and discussions were explained below.
