|Title:||Rise in nitrous oxide levels due to fossil fuel combustion in urban atmosphere|
Das, Surendra Nath
|Abstract:||<smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="City"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place" downloadurl="http://www.5iantlavalamp.com/"> 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 N<sub>2</sub>O concentration in air was above the ambient value (~419-428 ppbv) at most busy traffic posts. Similarly, at posts having low traffic density, the N<sub>2</sub>O level was (~228 ppbv). Wide variations were observed for N<sub>2</sub>O 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. </smarttagtype></smarttagtype>|
