The purpose of this study was to analyze the health risks of benzene exposure, on human health, especially for workers/employees engaged in the oil industry. To assess the health effects of benzene on workers, it was obtained from health data of workers exposed to benzene in the work environment. Acute exposure (14 days), moderate exposure (15-364 days) and chronic exposure (365 days) are workplaces where benzene exposure is below the Minimum Risk Level (MRL) value of inhaled benzene exposure that is reduced by ATSDR by acute, moderate and chronic exposure, respectively, to benzene. The threshold value of physical and chemical variables in the workplace (1.59 mg/m3) is also set by the Regulation. ATSDR-reduced exposure to toluene (7.6 mg/m3) is below the MRL for chronic inhalation exposure, while acute exposure (3.8 mg/m3) is well below the MRL for chronic inhalation exposure. Symptoms of headache, weariness, and respiratory irritation can be caused by Benzene exposure that exceeds the threshold value and biological exposure index. blood-forming cells and bone marrow dysfunction as well as neurological or reproductive system disorders. After conducting a risk analysis, an overall picture of the risks will be obtained. The results of risk analysis can be qualitative or quantitative depending on the technique or method used. Risk analysis will also provide an overview of the level of risk from various potential hazards that exist.
