Abstract

Occupational health risks have grown in recent years as one of the major public health issues around the world، as exposure to hydrocarbons has been associated with many toxic effects on various body systems and organs، therefore this study aimed to analyze the effects of exposure to hydrocarbons on some blood and biochemical variables among workers. In the Sebha oil and gas depot، this study was conducted in the city of Sebha during the period between September 20 20،22 to January 20، 2023، Faculty of Science، Sebha University، was selected as a control group،The study presentof 100 participants، 60 of and on direct contact and exposure to petroleum products at a rate of six hours per day، and comparing them with 40 people who do not have a history of occupational exposure to hydrocarbon materials. The average age of the warehouse workers was 43.38 ± 11.38 years، and the control group was 40.40 ± 9.11 years, there was a significant increase in WBC and exposure periods had no significant effect on all types White blood cells. The results also showed that there were no significant differences between the two groups in RBC blood cells and their indicators. According to the smoking condition، the results showed a significant significant increase in the level of HGB، HCT RDWS between the two groups,As well as the number of platelets PLT did not show any significant,This study concluded that exposure to hydrocarbons is associated with an increase in some types of white blood lymphocytes، monocytes and granulocytes. while smoking with exposure to hydrocarbons led to a significant increase in white blood cells، granulocytes، hemoglobin level، hematocrit، and distribution capacity of red blood cells. Increasing the exposure period also led to an increase in the number of red blood cells، the average muscle hemoglobin، and the average concentration of hemoglobin in the cell.
