Assessment of pollution with heavy metals in Soil the industrial area of Left Mosul city

The current study evaluated indicators of heavy metal pollution (Pb, Cd, Ni, Cr , Co, and Sb) of the surface layer of calcareous soils in the industrial areas on the left side, southeast of Mosul. Soil samples were collected at a depth of (0- 30 cm) from nine different sites that covered the study area, and the total content of heavy metals was estimated to calculate the contamination factor (CF), Enrichment Factor (EF), Geoaccumulation Index (Igeo), and Combined Pollution Index (CPI). The results indicated that the total content of heavy metals was as follows: Pb (0.74-3.89), Cd (0.1-0.17), Ni (188.63-226.21), Cr (60.8-95.06), Co (10.99-12.68), Sb (1.14-10.66) mg.kg-1, as the study showed that the average values of CF for the studied elements (Pb, Cd, Ni, Cr , Co, and Sb) were as follows (0.11, 1.13, 10.35, 0.77, 1.20 and 25.82), respectively, while the average Enrichment Factor (EF) values were (0.17, 1.70, 15.46, 1.15 , 1.79 and 39.17) respectively, while the Igeo evaluation rates were uncontaminated with (Pb, Cd, Cr, Co) and Heavily to very heavily polluted by (Ni, Sb) in all study sites. Moreover, CPI values were determined for all heavy metals studied in all sites as high polluted.
