Assessment of Ozone and Nitrogen Oxides Variations in Urban Region of Patna, India

Abstract

Increasing levels of ozone and nitrogen oxides may have damaging effects on the ambient environment, vegetation, public health and climate. Therefore, ozone chemistry is crucial to understand in fast-growing urban regions. This article reports on the determination of ozone and nitrogen oxides in the urban region of Patna, India. The aims of present study involve temporal variations of gaseous pollutants and source analysis. The occurrence of pollutants is dependent on meteorological factors along with local and distant sources. The findings may be useful for policymakers to formulate effective pollution-reducing strategies in the case of the new fast-growing urban city.
