摘要：Fireworks displayed during festival celebrations can cause acute short-term air pollution. Fireworks cause the release of harmful gases in the atmosphere which in turn irritates the eyes and other diseases like asthma. Due to the increased use of fireworks in Diwali in past years, the problem has taken a big form after the recent development of smog clouds surrounding the city suffocating its residents and causing watery eyes, etc. which has motivated our study. Previous studies indicated that the concentrations of above air pollutants during the Diwali festival were several folds higher as compared to the 24-h standards of National Ambient Air Quality Standards of India (NAAQS) given by the Central Pollution Control Board (CPCB), India. Concentrations of metallic elements analyzed in fireworks aerosol samples in previous studies in India reported its higher contribution during the Diwali festival as compared to the limit value of NAAQS of India. This study investigates the effects of fireworks on the air quality over the Indian capital city of Delhi during the festival of light known as "Diwali". The effects of firecrackers during the festival were assessed using the data of the Central Pollution Control Board for ambient concentrations of various air pollutants, such as Sulphur dioxide, nitrogen dioxide, and particulate matter with a diameter less than 2.5 and 10 碌m. The concentration of air pollutants, such as suspended particulate matter, PM10, PM2.5, SO2, and NO2 were monitored for five consecutive days during Deepawali in Delhi. The concentrations of gaseous pollutants, such as SO2 and NO2, well as particulate pollutants, such as PM10 and PM2.5 was found about 2-7 times higher during the day of the festival because of the use of the huge quantity of firecrackers that emits a large number of pollutants into the atmosphere. This review and analysis of data suggested the need of developing appropriate strategies to control the use of firecrackers during the festival of light especially in the major cities of India to protect human health.
