Did you know how firecrackers affect your health?

A 2007 study, ‘Recreational Atmospheric Pollution Episodes: Inhalable Metalliferous Particles from Firework Displays’, published in Atmospheric Environment, had found that children are particular susceptible to pollution caused by firecrackers.

Studies in Europe, Canada and China have found strong correlation between increases in use of fireworks, and variations in air quality. Most of these studies have focused on festivals such as the Yanshui Festival in Taiwan, Montreal International Fireworks competition, Lantern Festival in Beijing, Guy Fawkes Night in the UK, etc. (AP Photo)

A 2014 study: ‘Potential Impact of Fireworks on Respiratory Health’, in a peer-reviewed journal of the Indian Chest Society, namely Lung India, Caroline Gouder and Stephen Montefort wrote: “Adults exposed to high levels of ambient air pollution have shown increased prevalence of chronic cough, phlegm, and breathlessness and are, therefore, at an increased risk of developing respiratory symptoms, asthma, chronic obstructive pulmonary disease, allergic rhinitis, lower respiratory tract infections, and lung cancers.”

Similarly, a 2007 study, ‘Recreational Atmospheric Pollution Episodes: Inhalable Metalliferous Particles from Firework Displays’, published in Atmospheric Environment, found that children in particular were susceptible air pollution caused by firecrackers, since their defences against particulate matter and other gaseous air pollutants were weaker. Also, children who were engaged in greater physical activity, also increased the intake of polluted air into their lungs. (AP Photo)

The amount of toxic gases released when a firecracker is lit-up depends on the composition of its four primary ingredients: namely oxidiser, fuel, colouring agents, and binder. (AP Photo)

The process of burning a firecracker requires oxygen, i.e. the oxidisers in fireworks and the chemicals release oxygen to allow the explosion to take place. Nitrates, chlorates and perchlorates are used most commonly. Fires need fuel to burn; the most common fuel in Indian fireworks is charcoal, says the Central Pollution Control Board (CPCB). The combination of fuel and oxidiser — or gunpowder — causes the explosion. (AP Photo)

Fireworks display terrific bright colours while exploding because of various chemical compounds called 'colouring agents' are present inside it. Aluminium compounds produce brilliant whites, barium nitrate produces greens, and the addition of copper results in blue light. Binders, according to the CPCB, “are used to hold the mixture of the firework together in a paste… the binders don’t actually begin to work until the firework has been lit and are potentially dangerous”.
