Evaluation Of Heavy Metals in Different Soils Contaminate with Diesel from Multiple Areas in Nineveh Government/ Iraq

The study included evaluating soil pollution with some heavy elements and statistically analyzing it in the road linking Mosul, Sinjar and the road linking Mosul, Duhok, included industrial and residential areas within Nineveh Governorate in the season autumn of 2024. Different sites were selected from the two roads with 8 samples at a depth of (0-15) cm for the surface soil. The research included measuring the physical and chemical properties controlling the distribution of heavy elements in the soil and comparing them with global determinants. Physical examinations of the soil texture showed that it ranges between (mixed, mixed sand, mixed sandy clay). The results of the chemical examinations showed that the soil was neutral to alkaline, as its rates varied between (7.5-7.9), and its highest value was in sample No. 2 on the road linking Mosul, Sinjar. The rates of electrical conductivity values of the soil ranged between (1.8-17.7) micro siemens / cm, in addition to the rates of organic matter values, which were between (3.13-5.2). The results of soil sample analysis showed that all industrial areas were polluted with zinc, as the average concentration of the element was (9.489) ppm, and sample No.1 was the most polluted area with the element. As for the chromium element, the concentration rates ranged between (0.104-0.657). The results of the study showed that there was a difference in the rates of cadmium concentrations in the soils of the study areas, as the highest rate was (0.444) ppm in sample No. (3) from the Mosul-Duhok Road, while the highest value of zinc was (20.5) ppm in sample No. (1) from the Mosul-Sinjar Road. there is a difference in the concentration rates of chromium in the soils of the study areas, as the highest rate was (0.657) ppm in sample No. (4) from the Mosul-Duhok Road.
