E-Journal Article: Firework-Induced Particulate and Heavy Metal Emissions During the Diwali Festival in Delhi, India
Abstract
This study deals with the temporal monitoring of air quality in a densely populated residential area of Delhi to assess the impact of firework displays on ambient concentrations of PM10, PM2.5, and trace metals in air particulates for pre-Diwali, Diwali, and post-Diwali festival times during 2012 and 2013. We monitored for particulate concentration, which causes adverse health effects, during morning and evening hours. The use of fireworks during Diwali increased 1.6–1.9 times in the concentration of PM10 and increased1.7–2.1 times in the concentration of PM2.5 as compared with pre- and post-Diwali during our monitoring in 2012. In 2013, however, PM10 concentration increased 1.5–2.0 times, and PM2.5 increased 1.7–2.2 times. The average concentration of particulates on the day of Diwali was higher in 2012 compared with 2013, which might be attributed to adverse meteorological conditions. The following average concentrations (in ?g/m3) were associated with particulates on Diwali in 2013, in order: aluminum (19.47) > magnesium (11.39) > sulfur (7.69) > potassium (6.50) > iron (0.74) > zinc (0.30) > lead (0.13) > copper (0.09).
