Ozone (O3), one of the most powerful oxidants known, is a naturally occurring allotrope of oxygen. At high levels in the troposphere it is phytotoxic as well as cytotoxic. It is a secondary air pollutant formed by complex photochemical oxidation reactions. In this study, the measured surface ozone with one of its precursor nitrogen dioxide (NO2) and important meteorological parameters at a semi-urban area during 2009-2010 has been analyzed. The maximum concentration of surface ozone was obtained during summer season (May 2009, 42.24 ppb) and the minimum was obtained during north east monsoon season (October 2009, 7.54 ppb). The results of this study show that the surface ozone concentration noticeably correlates with temperature (r=0.73) and NO2 (r=0.93). It was found that not a single ozone exceedance day occurs during the period of study and the level of O3 concentration is within the limit of WHO recommendation (50 ppb).

Abstract


Ozone (O3), one of the most powerful oxidants known, is a naturally occurring allotrope of oxygen. At high levels in the troposphere it is phytotoxic as well as cytotoxic. It is a secondary air pollutant formed by complex photochemical oxidation reactions. In this study, the measured surface ozone with one of its precursor nitrogen dioxide (NO2) and important meteorological parameters at a semi-urban area during 2009-2010 has been analyzed. The maximum concentration of surface ozone was obtained during summer season (May 2009, 42.24 ppb) and the minimum was obtained during north east monsoon season (October 2009, 7.54 ppb). The results of this study show that the surface ozone concentration noticeably correlates with temperature (r=0.73) and NO2 (r=0.93). It was found that not a single ozone exceedance day occurs during the period of study and the level of O3 concentration is within the limit of WHO recommendation (50 ppb).
