Abstract

The present study was aimed to evaluate the effects of some heavy metals (Hg, pb& Cd) and MDA on total antioxidant capacity (TAC) in blood of gasoline station workers in Basra Governorate/Iraq. The results revealed that Hg, Pb, Cd and MDA levels significantly higher in the blood of workers than healthy controls (p 0.0001) respectively. This study also found a significant increase in the level of TAC (p 0.05) in serum of workers compared to the control. The results confirmed that the level of serum TAC was negatived and significantly correlated with Hg, Pb, Cd and MDA levels (p 0.0001, r= -0.39, r= -0. 3, r= -0.551, r= -0.671) respectively, in gasoline station workers. The present study suggests the chronic exposure to gasoline in the work place (gasoline stations) led to increase in the oxidative stress in workers which decreased the antioxidant enzyme levels.This behavior might give an indicator for the oxidants that take place in exposed persons.
