Özet:

In this study, Particulate matter (PM), Carbon dioxide (CO2), Carbon monoxide (CO) levels were measured in different types of indoor environments (homes) and, in parallel, at their outdoors for a year. The study was conducted on a monthly basis at different sampling points of three towns of Çanakkale. According to the study results, indoor air quality varied among the homes as well as the towns of the city. Average values of indoor temperature and relative humidity occurred around 22 °C and 49%, respectively. The mean PM and CO2 levels measured in indoor air of Çan, Lapseki, and in Central towns, in descending order. Temporal variations were found for the measured parameters (PM, CO, and CO2) and, in general, concentrations were higher in winter months than rest of the year. Generally, both indoor and outdoor levels of PM, CO, and CO2 showed statistically significant monthly variations (p<0.05). The indoor CO level was generally measured higher during heating season, whereas it was found to be lower in the summer. The fact that Indoor-to-Outdoor (I/O) ratios, calculated for the measured air quality parameters were above the unity, it indicated that the contribution of indoor sources was important on the PM, CO and CO2 levels. Therefore, it is possible to reduce the influence of indoor pollutant sources by increasing the air circulation by providing adequate ventilation amount in indoor environments.
