Air pollution is one of the most important environmental problems in Balikesir, situated in the western part of Turkey, during the winter periods. The unfavorable climate as well as the city's topography, and inappropriate fuel usage cause serious air pollution problems. The air pollutant concentrations in the city have a close relationship with meteorological parameters. In the present study, the relationship between daily average total suspended particulate (TSP) and sulphur dioxide (SO2) concentrations measured between 1999--2005 winter seasons were correlated with meteorological factors, such as wind speed, temperature, relative humidity and pressure. This statistical analysis was achieved using the stepwise multiple linear regression method. According to the results obtained through the analysis, higher TSP and SO2 concentrations are strongly related to colder temperatures, lower wind speed, higher atmospheric pressure and higher relative humidity. The statistical models of SO2 and TSP gave correlation coefficient values (R2) of 0.735 and 0.656, respectively.

People spend about 90% of their time indoors. Therefore, the air of the internal environment must provide healthy and comfortable conditions. Values such as temperature and humidity constitute the thermal comfort parameters of the internal environment. Most people feel comfortable between 20-25.5 °C and 30-60 % temperature and humidity ranges, respectively. In this study, the central province of Balıkesir is divided into 3 zones in terms of socioeconomic structure. In these regions, temperature and relative humidity levels of 29 houses during the winter were measured Nadir İLTEN,
