Ozone is a secondary pollutant and greenhouse gas that is formed from molecular oxygen in the presence of sunlight and nitrogen oxides. The extent of production also depends on the presence of volatile hydrocarbons, carbon monoxide and methane. But we have discovered a surprising source of ozone which is generated in spontaneous bursts even in the absence of sunlight and nitrogen oxides — namely, the exuberant mass of colour-emitting sparklers that are lit during the Diwali festivities, which… Expand
Artificial O3 formation during fireworks
In several previous studies emission of ozone (O3) during fireworks has been reported, which was attributed to either photolysis of molecular oxygen (O2) or nitrogen dioxide (NO2) by short/near UVExpand
Surface ozone pollution during the festival of Diwali, New Delhi, India
Pollution from carbon monoxide, nitrogen dioxide, sulphate and suspended particulate matter due to ignition of fireworks during the festival of Diwali is well established. Although surface ozoneExpand

TLDR
The results suggest that previous understanding of the ozone formation mechanism during fireworks is misunderstood and that Benzene and phenol might be major contributors to the artificial ozone signal. Expand
Real-Time Measurements of Ozone and UV Radiation during Pyrotechnic Displays
ABSTRACTReal-time measurements of ozone, NOx, aerosols and radiation were performed very close to the launch area of high intensity pyrotechnic spectacles, the so-called Mascletas, typical ofExpand
The impact of fireworks on airborne particles
Abstract Fireworks are one of the most unusual sources of pollution in atmosphere; although transient, these pollution episodes are responsible for high concentrations of particles (especially metalsExpand
Firework Induced Large Increase in Trace Gases and Black Carbon at Dibrugarh, India
Religious, occasional and annual fire work festivals worldwide are found to introduce high concentrations of pollutant gases and particulate matter into the atmosphere. These in turn alters the airExpand

Abstract Pyrotechnics (fireworks) displays are common for many cultures worldwide, with Independence Day celebrations occurring annually on July 4th as the most notable in the U.S. Given an episodicExpand
Respirable Mercury Particulates and Other Chemical Constituents in Festival Aerosols in Delhi
The display of fireworks emits a large amount of gaseous and particulate pollutants which accumulate in the atmosphere for a short period and have adverse effects on human health, and climate.Expand
Atmospheric pollution in a semi-urban, coastal region in India following festival seasons
Abstract The traditional Vishu festival in the state of Kerala in South India is celebrated in April with extensive coordinated fireworks display. The influence of these celebrations on the immediateExpand
Tropospheric ozone pollution in India: effects on crop yield and product quality
TLDR
There is a substantial spatial difference in O3 distribution at different places displaying variable O3 concentrations due to seasonal and geographical variations, and this review further recognizes the major information lacuna and also highlights future perspectives to get the grips with rising trend of ground level O3 pollution.
