The aim of this study is to determine the benzene, toluene, and xylenes (BTX) concentration levels in and around fuel station and its expected health risks in the City of Dammam and Al-Khobar, Saudi Arabia.
Forty fuel dispensing facilities were randomly selected on the basis of three different areas, residential, traffic intersection, and petrol pump locations (refueling stations). coconut shell charcoal cartridges were used for samples collection and portable Ambient Analyzer was used for measuring BTX (benzene, toluene, and xylenes) concentration.
Results show that the average concentration of benzene, toluene, and xylenes level around fuel stations was 10.30, 4.09, and 2.47 ppm, respectively. All means of concentration values of BTX around residential, traffic intersection, and fuel stations are exceeding the limits of air quality standards values ( < 0.01). The mean concentration of BTX around residential area, side street, and direct street was benzene 8, 12.2, and 11.5 ppm, toluene 2.5, 5.95, and 3.37 ppm, and xylenes 2, 2.13, and 2.7 ppm. Hazard Quotient (HQ) was more than >1 which showed that carcinogenic probability has increased those exposed to this toxic chemical.
Ambient concentration of BTX was high compare to neighboring residential area and 100 m from the fuel station which can negatively affect on health of several residences. The Environmental contamination associated with BTX in petrol fuel stations impulses the necessity of preventive programs to reduce further air quality deterioration and reduce the expected health risks.
本研究旨在测定沙特阿拉伯达曼市和胡拜尔市加油站及其周边地区的苯、甲苯和二甲苯（BTX）浓度水平及其预期健康风险。
根据三个不同区域，即居民区、交通路口和加油站位置（加油站点），随机选择了40个加油设施。使用椰壳活性炭管进行样品采集，并使用便携式环境分析仪测量BTX（苯、甲苯和二甲苯）浓度。
结果表明，加油站周围苯、甲苯和二甲苯的平均浓度分别为10.30 ppm、4.09 ppm和2.47 ppm。居民区、交通路口和加油站周围BTX的所有浓度平均值均超过空气质量标准值的限值（<0.01）。居民区、侧街和主干道周围BTX的平均浓度为：苯8 ppm、12.2 ppm和11.5 ppm，甲苯2.5 ppm、5.95 ppm和3.37 ppm，二甲苯2 ppm、2.13 ppm和2.7 ppm。危害商（HQ）大于>1，表明接触这种有毒化学物质的致癌概率增加。
与邻近居民区和距离加油站100米处相比，BTX的环境浓度较高，这可能会对一些居民的健康产生负面影响。汽油加油站中与BTX相关的环境污染促使有必要制定预防计划，以进一步减少空气质量恶化并降低预期的健康风险。
