The correlation between trance elements and biochemical and blood parameters among petrol filed attendance in Basrah city, southern of Iraq

The current study as case control was intended to evaluate the potential petrol exposure effects on the blood parameters of workers at field and comparing them with workers at office in province of Basrah, Iraq. From petrol filed, the blood of 53 individuals being exposed and other blood individual’s samples of 53 as group being unexposed were collected. Full blood picture analysis was done utilizing hematology analyzer that fully automated in Nassriy hospital. Level of cadmium (Cd) and Mercury (Hg) were assessed. The results displayed significant rising in level of Cd and Hg in refinery field workers. Additionally, most biomarkers as blood (out of 24 biomarkers) were not changed significantly in both study groups. Nevertheless, RBC, WBC, HB and PCV% were increased significantly in oil field workers comparison to non-oil field workers. Furthermore, the total platelets number (PLT) was declined significantly comparing to the control. No significant relations were found between the work duration, age and all parameters as blood. It can be concluded that exposure to petrol of a potential for inducing blood disease among working people at Basarh fields besides no significant changes for most blood workers biomarkers at field in comparing to the office working group as control. We also reported the increase in ALKA and ALT in filed attendance workers comparing to the control although, no change noticed in urea and serum proteins and other parameters comprised in the current study. Based on the results, occupations in oil filed in Iraq needs more attention and tests to make sure they are safe. Lack of secretariat and safety procedures in oil filed and diminished of periodical physical exams certainly will lead to numerous health effects on workers and their families.
