Background and Purpose: BTEX compounds cause adverse effects on thehealth of employees in various industries, including the oil industry. This studywas conducted with the aim of measuring these compounds and their effecton serum lipid parameters of Abadan oil refinery workers.Materials and Methods: In this study, 80 workers (40 exposed peoplefrom operational units and 40 non-exposed people from administrativedepartments) were investigated. Sampling and measurement of employees’respiratory area was done using individual sampling pump and measurementof lipid parameters of employees’ blood was done using commercial kits ofPars Azmoun company.Results: The obtained results showed that the average concentration oftoluene, ethylbenzene and xylene compounds in the respiratory area ofthe exposed employees was lower than the standard limit, but the averageconcentration of benzene compound was higher than the recommendedstandard limit. The results obtained from the comparison of blood serum lipidparameters showed that there is no significant difference between the twogroups of exposed and non-exposed employees. The results of Spearman’stest did not find any significant relationship between these parameters anddemographic characteristics in the two groups. However, Pearson’s statisticaltest showed that there is a significant relationship between some blood serumlipid parameters in two groups, and in both groups of employees, the averageblood plasma lipid parameter was higher than the normal range.Conclusion: The results showed that the concentration of benzene compoundis higher than the permissible limit of the standards and the effect ofbenzene on employees should be prevented with adequate engineering andmanagement controls and periodic inspection.
