Assessment of heavy metals in human blood for workers in Al-Gharraf oil field, Dhi-Qar governorate, Iraq.

Heavy metal contamination in the environment has attracted attention in recent decades due to its accumulation in soil and water, as well as the human body.heavy metals have a significant health risk when Increased concentration level and duration exposure. In this study, Specifically, we looked at the presence of certain heavy metals, such as lead (Pb), Cadmium (Cd), copper (Cu), Nickel (Ni), in the human blood of oil using atomic absorption spectroscopy (AAS). The results showed that average concentrations (ppm) of Pb, Cd, Cu and Ni for the workers in oil field were 0.094, 0.177, 0.462 and 0.042 respectively. While, the average concentrations of Pb, Cd, Cu and Ni for the non-workers were 0.044 ppm, 0.048 ppm, 0.414 ppm and 0.005 ppm respectively. The conclusion of this study, there are direct effected of increasing the concentration of the working from working environment and duration of work. [ABSTRACT FROM AUTHOR]
