Impact of fireworks on ambient air quality: a case study
Nasir, U.P. & Brahmaiah, D.
Abstract
Fireworks activity causes short-term air pollution.
The festival of Diwali is celebrated with firecrackers
in India during October/November every year. The ambient
air quality was assessed in Vadodara city, Gujarat state of
India during Diwali festival for the consecutive years 2009,
2010, and 2011. During the festival day, the average concentration
of PM10 was increased 35 times compared with
a normal day before Diwali. Similarly, concentration of
SO2 has increased 23 times and NOx has increased 3 times
on the festival day. The diurnal pattern of the above pollutants
showed an increase in the night. Air quality index
calculated for 24 h average during Diwali 2009 in two
stations exceeded a value of 125 indicating severe air
pollution in Vadodara city. It is also confirmed that the
yearly pollution load is getting increased in Vadodara city
as the air quality index value has a gradual increase from
2009 to 2011. The good correlation coefficient between
different pollutants confirmed the firework as the prime
source of pollution. Based on PM10 concentration, the
highest mortality rate was found to be 30.4 %. The shortterm
high accumulation of PM10 is a matter of serious
concern for city dwellers as it can penetrate deep into the
lungs and cause many respiratory and cardiovascular
diseases.
