What effects do fireworks and bonfires have on Air Pollution?
A cocktail of chemicals produces the bright colours and effects in fireworks. Fireworks emit light, heat and sound energy along with carbon dioxide and other gasses and residues. The exact emissions will depend on the firework, but as gunpowder is a main component, sulpher compounds are emitted, along with metal oxides and small amounts of particulates*. Organic compounds including minute amouts of polycyclic aromatic hydrocarbons, dioxins** and furans are also released. On and around Bonfire Night (November 5th), there is often a noticable increase in air pollution from particulates and dioxins. Approximately 14% of UK dioxin emissions are produced around Bonfire Night – most of this coming from bonfires rather than fireworks. Current research indicates that deposits of pollutants from fireworks do not pose a risk to soil or water. *(particulates are finely divided materials which are dispersed into the air from combustion, industry and natural sources. They can irratate the eyes, nos
