The wintertime concentrations and diel cycles of n-alkanes and polycyclic aromatic hydrocarbons (PAHs) associated to atmospheric particulate matter with aerodynamic diameter lesser than 10 μm were determined at the biggest student residence in Algeria located in Bab-Ezzouar, 15 km southeast from Algiers city area. Samplings were carried out from December 2009 to March 2010, and organic compounds were characterized using gas chromatography coupled with mass spectrometric detection. Volatile PAHs were also monitored inside some student residence rooms in order to evaluate the impact of indoor air pollution to student health. For the sake of comparison, aerial concentrations of n-alkanes and PAHs were determined in parallel in the Oued Smar industrial zone and two suburban areas, all located in Algiers. Total concentrations recorded in CUB1 student residence ranged from 101 to 204 ng m(-3) for n-alkanes and from 8 to 87 ng m(-3) for PAHs. Diel cycles have shown that, while concentrations of n-alkanes peaked at morning and afternoon-evening and dropped at night, those of PAHs exhibited higher levels at morning and night and lower levels at afternoon-evening, likely due to the reactivity of some PAHs. As expected, the indoor levels of PAHs were larger than in the outdoor of the student residence and were of serious health concern. Overall, the concentrations of n-alkanes and PAHs were as high as those observed in the industrial zone and higher than the two suburban sites.
在阿尔及利亚最大的学生宿舍（位于阿尔及尔市区东南 15 公里的巴巴祖阿尔），测定了冬季大气颗粒物中小于 10μm 空气动力学直径的 n-烷烃和多环芳烃（PAHs）的浓度和日变化周期。采样时间为 2009 年 12 月至 2010 年 3 月，使用气相色谱-质谱联用仪对有机化合物进行了表征。还监测了一些学生宿舍内的挥发性 PAHs，以评估室内空气污染对学生健康的影响。为了进行比较，还平行测定了奥里德·斯马尔工业区以及阿尔及尔的两个郊区空气中 n-烷烃和 PAHs 的浓度。CUB1 学生宿舍记录的总浓度范围为 n-烷烃 101-204ng/m3，PAHs 8-87ng/m3。日变化周期表明，n-烷烃的浓度在早晚高峰时达到峰值，在夜间下降，而 PAHs 的浓度在早晚高峰时较高，在下午-傍晚时较低，可能是由于某些 PAHs 的反应性所致。正如预期的那样，室内 PAHs 浓度高于学生宿舍外，对健康构成严重威胁。总体而言，n-烷烃和 PAHs 的浓度与工业区相当，高于两个郊区。
