Assessment of Some Heavy Metal Concentrations in Drilling Mud samples in Az Zubair Oil Field, Basra, Iraq
Engineering and Technology Journal,
2018, Volume 36, Issue 1B, Pages 68-75
AbstractAnalysis of eight heavy metal concentrations (Cd, Cr, Cu, Fe, Mn,
Ni, Pb and Zn) of 14 drilling mud samples collected from oil well at different
depths which is located in AZ Zubair oil field-Basra was done in this study .
The samples were measured using atomic absorption spectrophotometry.
Obtained results indicated that the heavy metal concentrations range from the
lowest value of 1.66mg/kg for Cd to the highest value of 1235.86mg/kg for
Fe. The abundance trend for the heavy metals concentration was in the
descending order of Fe, Mn, Ni, Cu, Cr, Zn, Pb, and Cd. Four parameters:
Enrichment Factor (EF), Contamination Factor (CF), Geo-accumulation
Index (Igeo) and Pollution Load Index (PLI) were assessed in order to
evaluate the degree of contamination.
