Chemicals compounds used as colourants in fireworks, and their impact on health.
|Blazing Reds||Lithium Compounds||Toxic, irritating fumes when burnt|
|Glittering Greens||Barium Nitrate||Can irritate respiratory tract, have possible radioactive fallout|
|Brilliant Whites||Aluminium||Contact dermatitis, bio-accumulation|
|Blues||Copper Compounds||Cancer risk, bio-accumulation|
|Glitters Effects||Antimony sulphide||Toxic smoke, possible carcinogen|
|Sulphur Dioxide||Acid rain|
|Potassium Nitrate||Carcinogenic, toxic dust|
|Ammonium / Potassium Perchlorate||Contaminate ground water, may cause thyroid problems|
|Lead Dioxide / Nitrate / Chloride||Development danger for unborn children, poisonous|
|Mercury||Toxic heavy metal, bio-accumulation|
|Nitric Oxide||Toxic, if inhaled|
|Nitrogen Dioxide||Highly toxic, if inhaled|
|Strontium Compounds||Can replace calcium in body, toxic|
How a specific exploding firework performs depends on how its four primary ingredients – oxidizer, fuel, colouring agents, and binder – combine.
Burning requires oxygen – the oxidisers in fireworks are chemicals that release oxygen to allow the explosion to take place. Nitrates, chlorates and perchlorates are used most commonly.
