| Tartalmi kivonat: | Air quality depends on physical and chemical factors and it can be influenced by meteorological processes in the atmosphere as well as by geographical and social conditions. The study aims at representing the air quality of Szeged using modified air stress indices ASIi and ASI2, which characterise annual and diurnal air pollution, respectively. The analysis is based on the mean daily values of the main air pollutants (N02 , SO2 and PM10) coming from the monitoring station of Szeged for the 10-year period 1997-2006. Features of ASIi and ASI2, as well as mean annual concentrations and the mean diurnal cycle of the pollutant levels are presented. According to the results, the mean annual air quality index (ASIi) shows small annual differences. The short-term (diurnal) air quality index (ASI2) is higher on weekdays and lower in the weekend. In the weekend the improvement of air quality reaches 13%. The maximum of the mean diurnal course expressed in percentage of the health limit exceeds the 100% (limit) only for PMi0. On the other hand, the mean values of the diurnal course of N0 2 and S02 are far below their health limit. |
