Poor indoor air quality (IAQ) can cause several respiratory diseases and symptoms. In this study, IAQ of 121 homes located in 3 different towns of Çanakkale, Turkey was monitored throughout a year. Target air pollutants were particulate matter, volatile organic compounds (VOCs), bioaerosols, and Carbon dioxide (CO₂), as well as air temperature and humidity. Moreover, pulmonary functions of the occupants were measured on a monthly basis. Also, occurrence of sick building syndrome (SBS) symptoms and other health related data were gathered from the occupants by a detailed questionnaire. The SBS is a situation related to indoor air pollution in which the occupants of a building experience health or comfort related adverse effects that appear to be associated directly to the time spent in the “sick” building. Results of this study showed that the highest indoor air pollutant levels were observed in Çan town and the lowest levels were observed in Central town. Indoor levels of bioaerosols, particulate matter, benzene, Cladosporium spp., and Penicillium spp. as well as pulmonary functions of the occupants showed statistically significant differences between the locations of the homes (p < 0.001). Factor analysis implied that both indoor and outdoor originated sources contributed to IAQ. Even though the predominant SBS symptoms varied seasonally and spatially among the study sites, fatigue, cold-flu like symptoms, and difficulty in concentration occurred frequently. Correlations were found among the occurrence of SBS symptoms, measured IAQ parameters, and personal factors (p < 0.05). Performing more studies from the health and IAQ points of view improve public awareness.

室内空气质量（IAQ）差会导致多种呼吸系统疾病和症状。在这项研究中，全年对位于土耳其Çanakkale的3个不同城镇的121套房屋的室内空气质量进行了监测。目标空气污染物为颗粒物，挥发性有机化合物（VOC），生物气溶胶和二氧化碳（CO ₂），以及空气的温度和湿度。此外，每月测量乘员的肺功能。此外，还通过详细的调查表从居住者那里收集了病态建筑综合症（SBS）症状的发生以及其他与健康相关的数据。SBS是一种与室内空气污染有关的情况，在这种情况下，建筑物的居住者会遇到与健康或舒适有关的不利影响，这些不利影响似乎与“病态”建筑物中所花费的时间直接相关。研究结果表明，Çan镇的室内空气污染物水平最高，而中心镇的水平最低。室内水平的生物气溶胶，颗粒物，苯，Cladosporium spp。和Penicilliumspp。以及居住者的肺功能在房屋位置之间显示出统计学上的显着差异（p  <0.001）。因子分析表明室内和室外来源均对室内空气质量有所贡献。即使主要的SBS症状在研究地点之间随季节和空间变化，也经常出现疲劳，感冒样症状和集中困难。在SBS症状的发生，测量的IAQ参数和个人因素之间发现了相关性（p  <0.05）。从健康和室内空气质量的角度进行更多的研究可以提高公众的意识。
