This research is focus on how the concentration of five pollutant i.e. NO2, NO, 03, PM10, PM2.5 changes in the absence and presence of vehicle during the 24 hour a day and diurnal variation taking R K Puram location in Delhi from Jan to Dec 2014. A correlation test also performs between NOx and Ox. Statistical analysis shows that during day wise variation of O3 and NO2, the concentration build up is high on Sunday as compared to other days whereas in particulate matter the concentration is high on Thursday. Diurnal variation of NO2 and O3 shows that the concentration of O3 is high between 8:00am to 18:00 pm and for No2 it is high from 16:00pm to 1:00am and crosses the permissible limit. On monthly basis NOx value is high during summer season due to high solar insulations and O3 value is high on summer season, the concentration of PM2.5 and PM10 is found maximum in November. NOX and OX is generated mostly by vehicular emission and therefore on daily average, it can be stated that vehicular emission contributes 59% of NOx of the Ox.
