In Saudi Arabia, fuel dispensing facilities commonly present around the residential places, educational institutions, and various health care facilities. Fuel pollutants such as benzene, toluene, and xylenes (BTX) and its alkyl derivatives are harmful to human health because of their toxic, mutagenic, or carcinogenic properties. The aim of this study was to determine the BTX concentration levels of common pollutants in and around fuel stations and their harmful health effects in the urban cites of KSA.
Forty fuel dispensing facilities were randomly selected on the basis of three different areas: residential, traffic intersection, and petrol pump locations (refueling stations). Portable ambient analyzer was used for measuring BTX concentration. -test was applied to determine the difference between these different areas.
All mean concentration values of pollutants such as BTX around residential, traffic intersection, and fuel stations are exceeding the limits of air quality standards values ( < 0.01). The mean levels of benzene are 10.3 and 11.07 ppm in Dammam and Khobar, respectively, and they exceed the reference level of 0.5 ppm. Hazard quotient was more than >1, which shows that carcinogenic probability has increased those who were living and working near fuel stations.
The results found that the high concentration of pollutants (BTX) is in the environment around fuel stations. The environmental contamination associated with BTX in petrol fuel stations impulses the necessity of preventive programs to reduce the further air quality deterioration and reduce the harmful health effects.
在沙特阿拉伯，燃油配送设施普遍存在于居民区、教育机构和各类医疗设施周边。苯、甲苯和二甲苯（BTX）等燃油污染物及其烷基衍生物因其毒性、致突变性或致癌性，对人体健康有害。本研究的目的是测定沙特阿拉伯王国城市中加油站及其周边常见污染物的BTX浓度水平及其对健康的有害影响。
根据三个不同区域（居民区、交通路口和加油站位置）随机选取40个燃油配送设施。使用便携式环境分析仪测量BTX浓度。采用t检验确定这些不同区域之间的差异。
居民区、交通路口和加油站周边的BTX等污染物的所有平均浓度值均超过空气质量标准值的限值（P<0.01）。达曼和胡拜尔的苯平均水平分别为10.3 ppm和11.07 ppm，超过了0.5 ppm的参考水平。危险商大于1，这表明在加油站附近生活和工作的人的致癌概率增加。
结果发现加油站周边环境中污染物（BTX）浓度较高。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，以减少空气质量的进一步恶化，并降低对健康的有害影响。
