الملخص EN

This research included study of some heavy metals and their pollution standards on effect of oil residues in Samawah oil refinery soil for Muthanna Government.

Heavy metals quantities in surface horizons soils of contaminated pedons were: Pb range from 120.27 to 285.70; Ni, 65.12-88.56; Cd, 10.00- 19.30 and Fe, 358.87-469.85mg kg-1.While lower horizons soils were: 59.26- 200.89; 29.66-63.21; 1.56-5.15 and 77.43-161.29mg kg-1 respectively.

But, in surface horizons soils of non-contaminated pedons were: 15.0-15.40, 3.52- 303.40, 2.00 and 71.63-76.37mg kg-1 of Pb, Ni, Cd and Fe, so in lower horizons soils were: 12.10-20.20, 3.09-284.60, 2.00 and 66.05-70.75mg kg-1 consecutively.
