Abstract
Present study assessed soil pollution by heavy metals and spent oil in three industrial
areas of Erbil City. Soil pH ranged from 7.53±0.017 to 8.25±0.012 and EC was ranged
between 103±0.882 and 465±9.955. Soils textures were loamy sand for south industry,
sandy for oil selling area and north industry while loamy for control soil. The ranges of
Pb, Zn and Ni were between 1.26±0.069 and 17.472±0.058; 1.439±0.006 and
3.078±0.003, and 0.399±0.061 and 0.982±0.048 ppm, respectively. The concentrations
of Cd and Cr were below the detection limit and Cu levels varied from 10.307±0.334
to 0.063±0.003 ppm, whereas Cu was not detected in some sites. The highest oil
residue was obtained in site 6. Oil and grease content for the groundwater samples in
the studied sites were zero. Pearson’s correlation showed a significant positive
correlation between Ni and moisture content and Ni and bulk density, beside to a
moderate correlation between Pb and Zn. A high significant negative correlation was
detected between bulk density and oil content. The lateral distribution of the heavy
metals and oil residues showed higher average concentrations at the point of impact
than 20 meters away. Relative Pollution Potential gave positive values for the metals
and oil contents in all sites.

Key Words: Soil pollution, Heavy metals, Oil residues, Industrial area
