Aim/Objectives: This study investigates the impact of petroleum product exposure on haematological parameters in workers from various sectors, including petrol attendants, tanker drivers, automobile mechanics, and N.N.P.C.L. staff in Abuja. Methodology: A total of 250 male participants were assessed by analyzing their venous blood for various haematological parameters. Results: Revealed no significant difference in white blood cell (WBC) counts between the control group and workers in most categories, except for auto mechanics, who showed significantly lower (p < 0.001) WBC levels. Red blood cell (RBC) counts were higher in N.N.P.C.L. staff compared to the control and other worker categories. Hemoglobin (Hb) levels were lower in the control group compared to mechanics (p < 0.001), tanker drivers (p = 0.003), and N.N.P.C.L. workers (p < 0.001), while petrol attendants had lower Hb than the other groups. Additionally, the control group had lower mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) compared to other groups. Platelet counts were significantly higher in N.N.P.C.L. staff compared to auto mechanics and tanker drivers, while petrol attendants had higher platelet levels than auto mechanics. Conclusion: These findings suggest that exposure to petroleum products can affect haematological health, particularly among auto mechanics, with notable variations in RBC, Hb, MCH, MCHC, and platelet counts. Further research is needed to understand the mechanisms behind these changes.
