Abstract

Temporal variation of PM 10 using 2-year data (January, 2007-December, 2008) of Delhi is presented. PM 10 varied from 42 to 200 μg m -3 over January to December, with an average 114. 1 ± 81. 1 μg m -3. They are comparable with the data collected by Central Pollution Control Board (National Agency which monitors data over the entire country in India) and are lower than National Ambient Air Quality (NAAQ) standard during monsoon, close to NAAQ during summer but higher in winter. Among CO, NO 2, SO 2, rainfall, temperature, and wind speed, PM 10 shows good correlation with CO. Also, PM 10, PM 2. 5, and PM 1 levels on Deepawali days when fireworks were displayed are presented. In these festive days, PM 10, PM 2. 5, and PM 1 levels were 723, 588, and 536 μg m -3 in 2007 and 501, 389, and 346 μg m -3 in 2008. PM 10, PM 2. 5, and PM 1 levels in 2008 were 1. 5 times lower than those in 2007 probably due to higher mixing height (446 m), temperature (23. 8°C), and winds (0. 36 ms -1). © 2011 Springer Science+Business Media B.V.
