Exposure to benzene, toluene, ethylbenzene, and xylene (BTEX) has been reported in gas stations. Exposure to BTEX can result in adverse health outcomes in workers such as cancer and neurological effects. The health risk assessments of exposure to BTEX could be useful in choosing suitable control measures. In this review, data from previous studies of gas station environments in Iran were collected from years 2000 to 2020. The health risk assessments were conducted through the estimation of cancer and noncancer risks using a Monte Carlo simulation based on the US Environmental Protection Agency method. The results showed that exposure to BTEX in some cities of Iran was greater than the occupational exposure limits. The results of cancer risk assessments demonstrated that cancer risk was not increased. However, results of noncancer risk assessments demonstrated that neurological toxicity from exposure to BTEX was significant in different cities of Iran. The health risk assessments indicated that workers at gas station are at health risk.
据报道，加油站存在苯、甲苯、乙苯和二甲苯（BTEX）暴露的情况。工人接触 BTEX 可能会导致癌症和神经影响等不良健康后果。接触 BTEX 的健康风险评估有助于选择合适的控制措施。在本次综述中，收集了 2000 年至 2020 年伊朗加油站环境的先前研究数据。通过使用基于美国环境保护署方法的蒙特卡罗模拟来估计癌症和非癌症风险，进行了健康风险评估。结果表明，伊朗一些城市的 BTEX 暴露量高于职业暴露限值。癌症风险评估结果表明，癌症风险并未增加。然而，非癌症风险评估结果表明，伊朗不同城市因接触 BTEX 导致的神经毒性显著。健康风险评估表明，加油站工人面临健康风险。
