The mass concentrations of coarse (PM10) and fine (PM2.5) particulate matter were measured in different classrooms and relevant indoors areas of Democritus University, School of Engineering, Xanthi, with portable aerosol monitoring equipment. Two sampling campaigns were conducted in different seasons. The results indicated that the average concentrations in classrooms ranged from 32-188 microg/m3 and 25-151 microg/m3 for PM10 and PM2.5, respectively. Concentration levels above 300 microg/m3 were usually recorded, while the PM2.5/PM10 ratio was about 0.8. As expected, PM10 and PM2.5 average concentrations were significantly higher in the open-access meeting place of common use, indicating the significance of student trespassing and occasional smoking in the deterioration of indoors air quality.
使用便携式气溶胶监测设备，在位于克桑西的德谟克利特大学工程学院的不同教室及相关室内区域，测量了粗颗粒物（PM10）和细颗粒物（PM2.5）的质量浓度。在不同季节开展了两次采样活动。结果表明，教室中PM10和PM2.5的平均浓度分别为32 - 188微克/立方米和25 - 151微克/立方米。通常记录到浓度水平高于300微克/立方米，而PM2.5/PM10比值约为0.8。正如预期的那样，在常用的开放式公共会议场所中，PM10和PM2.5的平均浓度显著更高，这表明学生擅自进入及偶尔吸烟对室内空气质量恶化具有重要影响。
