Abstract
This study is focused on the determination of some heavy metals levels (Se, Pb and Cd) with the study of biochemical parameters in blood samples, such as superoxide dismutases (SOD), catalases (CAT), glutathione peroxidases (GPX), glutathione reductases (GRX), vitamin C and vitamin. The samples were collected from 50 individuals at four distinct fuel stations in Kirkuk city in Iraq. To obtain the practical data, atomic absorption spectrometer, UV spectrophotometer and high performance liquid chromatography were used. The results indicated remarkable differences in the concentrations of Se, Pb and Cd in the analyzed samples compared to the control group. These Levels were lower in fuel station workers, whereas and the Pb and Cd concentrations were higher in their blood. Additionally, the results of chemical variables showed a decline in the antioxidant concentrations (SOD, GPx, Vit C, Vit E). In terms of oxidative stress (MDA), there was a significant increase in its concentration among the fuel station workers. In addition, the concentration of toxic heavy metals (Pb, Cd) in the soil of fuel stations was measured using the graphite furnace atomic absorption spectrometer. The Pb and Cd levels in the soil were within the permissible limits, indicating no adverse impact of on the soil.
