Genotoxic Effects of Lead and Cadmium on DNA of Some Fuel Stations Workers Blood in Hilla City

Abstract

The study included the genotoxic effects of lead and cadmium on DNA damage of 60 workers of some fuel stations in Hilla city. The results revealed a significant differences (P<0.05) of lead and cadmium, the concentrations of Pb+2 in blood of control (mean ±SD) was 6.3±0.41 μg/dl while in blood of workers who exposed to fuel for one year, three years and five years were significantly increased and reached (15.5±2.46, 27.4±11.6 and 44.5±17.8) μg/dl respectively. Cadmium concentrations in blood of control was nil while in workers were significantly increased (5±0.72, 12.2±2.6 and 15.3±4.21) μg/dl respectively. Damage criteria was increased significantly (P≤ 0.05) with time of exposure to fuel in comparison with control.
