In this study, the ambient benzene concentrations were measured in 7 air quality monitoring stations in Greece. The pollutant measurements were continuously being collected from the air quality monitoring network of the country through a calendar year (from 1^st January 2016 to 31^st December 2016). The monitoring stations were classified as Urban Traffic, Urban-Industrial, Suburban-Industrial and Urban Background according to the regional type zone. The highest ambient benzene concentrations were measured during the winter period while the lowest ones were measured during the summer months. The annual mean values of benzene concentrations varied between 0.81 ± 0.56 μg/m³ (in Elefsina station) and 5.63 ± 3.68 μg/m³ (in Patission station) across the air quality monitoring stations under study.

In addition, a health risk assessment was carried out in order to determine the effects of ambient benzene on the population health in Greece, considering both cancer and non-cancer effects. We calculated the Integrated Lifetime Cancer Risk (ILTCR) associated with the inhalation exposure to ambient benzene. Regarding the non-cancer effects, we estimated the Hazard Quotient (HQ) values. Moreover, the quantification of the Environmental Burden of Disease (EBD), due to the exposure to ambient benzene was calculated considering 4 exposure scenarios. These scenarios were based on the annual benzene concentrations detected in the country. Our analysis revealed that the exposure to ambient benzene in Greece causes an amount of annual Disability-Adjusted Life Years (DALYs) which varied between 0.262 and 0.655 DALYs lost per 100‚000 inhabitants.

在这项研究中，在希腊的7个空气质量监测站中测量了环境苯浓度。污染物测量不断地从通过历年国家的空气质量监测网络（从1收集^日2016年1月31^日2016年12月）。根据区域类型区域，监测站分为城市交通，城市工业，郊区工业和城市背景。在冬季测量最高的环境苯浓度，而在夏季测量最低的浓度。苯浓度的年平均值在0.81±0.56μg/ m ³（在Elefsina站）和5.63±3.68μg/ m ^3之间（位于Patission站）跨研究中的空气质量监测站。

此外，还进行了健康风险评估，以确定环境苯对希腊人口健康的影响，同时考虑了癌症和非癌症的影响。我们计算了与吸入环境苯有关的综合终生癌症风险（ILTCR）。关于非癌症影响，我们估算了危险商（HQ）值。此外，考虑到4种暴露场景，计算了由于暴露于环境苯而导致的环境疾病负担（EBD）的定量。这些方案是根据该国检测到的年苯浓度计算的。我们的分析表明，希腊暴露于环境苯会导致每年的残疾调整生命年（DALYs），每10万居民损失0.262至0.655 DALYs。
