Atmospheric concentrations of benzene, toluene, ethylbenzene, and xylenes (o-xylene and m,p-xylene) were assessed in the Tricity area (Gdańsk-Sopot-Gdynia, Poland) with the use of two types of passive samplers: permeation (homemade passive samplers) and diffusive (Radiello and Orsa 5). Samples were collected during 2008 at selected sites in the Tricity area at monitoring stations belonging to the agency of Regional Air Quality Monitoring Foundation. The field study was conducted to compare the performance of these two different types of passive samplers. A statistical approach was formulated, and the experimental data were evaluated using the paired t test, Wilcoxon signed rank-sum test, and Friedman analysis of variance. All the statistical results confirm the hypothesis that the differences between the performances of the three sampling devices are highly significant. Despite the fact that data obtained with the homemade passive sampler indicated that the results were higher compared with those for the Radiello and Orsa 5 diffusive samplers, the authors note that all differences between the homemade permeation sampler and the Radiello and Orsa 5 diffusive samplers are positive.
使用两种类型的被动采样器（渗透型[自制被动采样器]和扩散型[Radiello 和 Orsa 5]）评估了波兰格但斯克-索波特-格丁尼亚三市地区（Tricity 地区）大气中的苯、甲苯、乙苯和二甲苯（邻二甲苯和间、对二甲苯）浓度。在 2008 年，在三市地区的选定地点，在属于区域空气质量监测基金会的监测站收集了样本。进行现场研究是为了比较这两种不同类型的被动采样器的性能。制定了一种统计方法，并使用配对 t 检验、Wilcoxon 符号秩和检验和 Friedman 方差分析对实验数据进行了评估。所有的统计结果都证实了这样一个假设，即三种采样设备性能之间的差异是非常显著的。尽管自制被动采样器获得的数据表明，结果与 Radiello 和 Orsa 5 扩散采样器相比更高，但作者注意到，自制渗透采样器与 Radiello 和 Orsa 5 扩散采样器之间的所有差异都是正的。
