Background: Exposure to high quantities of benzene and its metabolites can cause hematotoxicity. However, the effects of exposure to low amounts remain unknown. Furthermore, the impacts on haemopoietic components may cause injury in other sections of the body later in life. Aim of the study: The purpose of this study is to use hemograms to analyze the effect of fuel exposure on the hematological parameters of filling station workers. Methods: A cross-sectional study was done from January 2022 to December 2022 in the Department of Physiology, Dhaka Medical College, Dhaka. A total number of 80 participants comprising 40 in study group and 40 in control group were recruited by purposive sampling technique after fulfilling the ethical aspect. The study group was again divided into group A1 (duration of exposure to fuel < 5 years), group A2 (duration of exposure to fuel 5 to 10 years) and group A3 (duration of exposure to fuel > 10 years). The study parameters were total and differential count of white blood cell (WBC), platelet count and mean platelet volume (MPV). Statistical analysis was done by a computer based statistical program SPSS windows version 26.0 as applicable. Results: In this study, total count of platelet (p< 0.001) was lower in study group compared with control group which was statistically significant. TC of WBC (p=0.363), neutrophil (p=0.266), lymphocyte (p=0.152), monocyte (p=0.640), eosinophil (p=0.332) and MPV (p=0.536) were not statistically significant. Furthermore, TC of WBC (p=0.337), total count of WBC and platelet count showed negative correlation with duration of exposure while neutrophil showed positive correlation. Conclusion: Long time exposure to fuel impacts haematological parameters.
