The carried out research analyzes air pollution in Raseiniai area. SO₂ and NO₂ exhaustion analysis is based on data for the period 2006–2009 provided by Kaunas Environmental protection department. Two air pollution research methods based on passive sorbents and bio indicators are proposed. The amount of SO₂ and NO₂ air pollutants is determined by conducting moss (Lichenes) tests and analyzing the fungus of maple leaves (Rhytisma acerinum). The performed research also describes the methods applied for analysis. Initial air quality monitoring using passive sorbents was carried out in the autumn of 2010. The primary results of this research revealed that the amount of analyzed air pollutants was below the permissible norm. In order to get reliable and objective results, research will be continued in the spring and summer of 2011.
