ABSTRACT
The metals accumulated in higher quantity in top horizons, followed by a decrease in mid horizons and thereafter irregular in lower horizons of the polluted soil profiles. The total metal content in polluted soil profiles also showed a similar distribution pattern with topsoil showing maximum metal levels. The total Fe (1.10 -1.56 mg/kg) and Mn (212-642 mg/kg) contents in all polluted soil were found to be non toxic in all of the profiles studied. At Hoskerhalli total Cu (123-240 mg/kg), Zn (83-406 mg/kg), Pb (13-361 mg/kg) Ni(80-141mg/kg) and Cr (108-438 mg/kg) at Bellabdur Cu (43-161 mg/kg) Cr (48-139 mg/kg) and at Doddabele 20-126 mg/kg of Cu were found to be within toxic range
