The environmental consequences of letting off firecrackers are very serious, ranging from health hazards to human beings, birds and animals to serious accidents. Many countries have banned firecrackers. In the present study, the authors investigated the health effects of fireworks. In addition, they analysed and assessed the environmental impact of bursting crackers on the ambient noise and air, quality of Delhi on the occasion of Deepawali festival. The study reveals that the average ambient noise levels at all the locations, with few exceptions, are exceeding the permissible limits on a normal day preceding Deepawali and on the Deepawali night over the entire data range (2003 to 2010). The average ambient noise levels have shown an increase of about 22 to 48 % and 9 to 14% in residential and community zones respectively in comparison to normal days of the year 2010. Regarding the air quality, the SO2 and NO2 concentration levels are mostly within the permissible limits on Deepawali days; but SPM and RSPM levels are 1.2 – 6.5 times and 2 – 13 times higher than the permissible limits on Deepawali days and is a serious concern due to their potential health hazards. Measures already taken by the government and suggestions / recommendations for making the festival environmental-friendly have also been indicated.
