Abstract:  During the study period (2001-2003), the population of Bhubaneswar city increased about 3.9 % while the number of registered vehicles went up about 13 %. The N2O concentration in air was above the ambient value (~419-428 ppbv) at most busy traffic posts. Similarly, at posts having low traffic density, the N2O level was (~228 ppbv). Wide variations were observed for N2O levels in the same station on different days because of varying traffic density. Seasonal variation could not be established due to less number of samples.
