Two measurement campaigns of volatile organic compounds (VOC) were carried out in the industrial city of Dunkerque, using Radiello passive samplers during winter (16-23 January) and summer (6-13 June) 2007. 174 compounds were identified belonging to six chemical families. Classifying sampling sites with similar chemical profiles by hierarchical ascending classification resulted in 4 groups that reflected the influence of the main industrial and urban sources of pollution. Also, the BTEX (Benzene, Toluene, Ethylbenzene and Xylenes) quantification allowed us to map their levels of concentration. Benzene and toluene (BT) showed high concentrations in Northern Dunkerque reflecting the influence of two industrial plants. Differences among spatial distributions of the BT concentrations over contrasted meteorological conditions were also observed. An atypical ratio of T/B in the summer samples led us to investigate the BTEX origins shedding light on the contribution of pollutants transported across various zones of VOC emissions situated in Europe.
在 2007 年冬季（1 月 16 日至 23 日）和夏季（6 月 6 日至 13 日），利用 Radiello 被动采样器在工业城市敦刻尔克进行了两次挥发性有机化合物（VOC）测量活动。共鉴定出 174 种化合物，分属于 6 个化学家族。通过层次递增分类对具有相似化学特征的采样点进行分类，得到了 4 个组，反映了主要工业和城市污染源的影响。此外，BTEX（苯、甲苯、乙苯和二甲苯）的定量分析也能够绘制出它们的浓度图。苯和甲苯（BT）在敦刻尔克北部的浓度较高，反映了两个工业工厂的影响。在不同的气象条件下，BT 浓度的空间分布也存在差异。夏季样品中出现了异常的 T/B 比值，促使我们对 BTEX 的来源进行了调查，揭示了污染物在跨越位于欧洲的不同 VOC 排放区时的输送贡献。
