Measurement of Complete Blood Count Among Fuel Benzene Station Workers in Khartoum State

Abstract

This is a analytical case - control study aimed to measure the change of some hematological parameters in one hundred benzene station workers, people involved in this study were male (18 – 52) years Sudanese benzene station workers in Khartoum state. The study period extended from April to June 2014. Investigation were performed by using automated cell count (sysmex device ) and manual thin blood film. This study assessed the measure hematological parameters in venous blood samples among 100 male as study group and 100 male as control by using sysmex device. The study reflected that the mean of HB (g/dl) , PCV (%) , RBCs x1012 /l. WBCsx 109, PLTs109/ L ,MCV(fl), MCH ( pg) . MCHc (%) , neutrophils count , lymphocytes count . monocytes count , eosinophils count and basophils count of workers exposed benzene as case group were : 12.6 , 38 , 3.4 , 3.3, 124, 68.7 , 27, 32.1 , 44 , 34 , 13 , 5 , 0.4 , respectively and the result obtained from control group revealed that the mean of HB (g/dl) , PCV (%) , RBCs x1012 /l. WBCsx 109, PLTs109/ L, MCV(fl), MCH ( pg) . MCHC (%) , neutrophils count , lymphocytes count . monocytes count , eosinophils count and basophils count were : 13.3 , 39 , 4.8 , 6.6 , 268 , 77 , 29 , 32.2 , 56 , 36 , 7 , 2 , 0 respectively The main conclusion derived from this study, there is significant effects in hematological parameters related to exposed to benzene with pancytopenia, eosinophilia, Basophilia and monocytosis and there is association between period of exposure to benzene and panctopenia with increase by increase of working duration.
