Abstract: | A study was conducted in the residential areas of Delhi, India, to assess the variation in ambient air quality and ambient
noise levels during pre-Diwali month (DM), Diwali day (DD) and post-Diwali month during the period 2006 to 2008. The use of
fireworks during DD showed 1.3 to 4.0 times increase in concentration of respirable particulate matter (PM10) and 1.6 to 2.5 times increase in concentration of total suspended particulate matter (TSP) than the concentration during
DM. There was a significant increase in sulfur dioxide (SO2) concentration but the concentration of nitrogen dioxide (NO2) did not show any considerable variation. Ambient noise level were 1.2 to 1.3 times higher than normal day. The study also
showed a strong correlation between PM10 and TSP (R
2 ≥ 0.9) and SO2 and NO2 (R
2 ≥ 0.9) on DD. The correlation between noise level and gaseous pollutant were moderate (R
2 ≥ 0.5). The average concentration of the pollutants during DD was found higher in 2007 which could be due to adverse meteorological
conditions. The statistical interpretation of data indicated that the celebration of Diwali festival affects the ambient air
and noise quality. The study would provide public awareness about the health risks associated with the celebrations of Diwali
festival so as to take proper precautions. |
