Air Pollution Monitoring ( Spm Sulphur Dioxide Nitrogen Dioxide) in and Around Mysore City

Abstract

Air pollution is worldwide phenomena and growing threat to human health and the natural environment. The ambient air quality monitoring is necessary as it is related to health of the citizens, spread of diseases and other conditions within a city. The present study is to assess the ambient air quality in Mysore city. Four sampling locations are selected with different anthropogenic activities i.e. residential, sensitive, commercial and industrial were identified in the city. The samples were collected for Suspended Particulate Matter (SPM), Sulphur dioxide (SO2), and Nitrogen dioxide (NO2) during February to April 2013 using High volume air sampler. Criteria
pollutants SPM, SO2 and NO2 measured in the sampling locations were found to be well within the prescribed standard.

Conclusion

The results obtained from the measurement of SPM, SO2 and NO2 from February to April 2013 in the selected sampling locations are well below the National Ambient Air Quality Standard. The concentration of pollutants varies with season, temperature, wind speed, vehicular density and industrial activities, etc.The population projection in Mysore city shows an increasing trend leading to change in the existing land use pattern, increase in the vehicular density and reduction of greenery and lung spaces affecting the air quality in the city.
