What You'll Learn
Fireworks release harmful metals and toxic elements
Fireworks are a major source of air pollution, releasing a host of contaminants that affect air quality and contribute to climate change. The combustion of fireworks produces toxic atmospheric pollutants, including particulate matter, sulphur dioxide, and nitric oxide. This toxic haze, known as particle pollution, is considered the most hazardous form of air pollution due to its detrimental effects on human health and the environment.
The brilliant colours in fireworks are often created using powdered metallic salts, which contribute to the release of harmful metals and toxic elements. Copper, for instance, produces blue colours, while barium provides green, and strontium yields red hues. Fireworks also frequently contain lead, which is banned in the United States but found in fireworks manufactured in other countries. Lead, titanium, strontium, and copper are commonly detected in air quality samples near celebrations involving fireworks.
These toxic metals have been shown to damage human cells and animal lung tissue. A study by Dr. Gordon and his team analysed 14 years of air quality samples and found elevated levels of toxic metals near Independence Day and New Year's Eve celebrations. The Black Cuckoo firecracker, a fountain-style firework, was found to be particularly harmful, causing ten times more damage to human cells than a non-toxic saline solution.
The smoke released by fireworks contains both coarse and fine particles, including nitrogen and sulfur compounds. These compounds can combine with oxygen to form nitric and sulfuric acids, which are harsh on the lungs. Individuals with existing respiratory or cardiac conditions, children, and elderly adults are especially vulnerable to the health effects of fireworks pollution.
The pollutants released by fireworks can spread over long distances, impacting air quality even in regions that do not host fireworks displays. This widespread pollution can have severe consequences for ecosystems, animals, and plants, in addition to human health and wellbeing. To mitigate these impacts, some cities are opting for greener alternatives, such as drone displays or laser spectacles, which reduce air pollution during celebrations.

They increase atmospheric gases like carbon monoxide and nitric oxide
Fireworks are a major source of atmospheric pollutants, including gases such as carbon monoxide and nitric oxide. These gases are formed during the combustion of fireworks and can have significant impacts on air quality and human health.
Carbon monoxide (CO) is a toxic gas that hinders the ability of living organisms, including humans, to transport oxygen throughout their bodies. It is produced during the combustion of fireworks and can reach harmful concentrations in the atmosphere. For example, during a firework event in downtown Minneapolis, Minnesota, for the Independence Day celebrations, researchers found that atmospheric carbon monoxide levels increased by 32%.
Nitric oxide (NO) is another harmful gas released by fireworks. It is toxic by inhalation and skin absorption. Fireworks contribute significantly to the atmospheric concentrations of nitric oxide, particularly during large-scale events. The Independence Day celebrations in the United States and the Diwali festival in India are examples of occasions where there were significant increases in nitric oxide levels due to fireworks.
These gases can spread over long distances and have long-lasting effects on air quality. While the smoke from fireworks typically dissipates within a few hours, individuals may still experience lingering health effects. Young children, the elderly, and people with respiratory or cardiac conditions are especially vulnerable to the harmful effects of these atmospheric gases.
The release of these gases into the atmosphere contributes to climate change and environmental damage. The combustion of fireworks adds to the overall pollution levels, affecting ecosystems, plants, and animals. Additionally, the toxic metals and particles emitted by fireworks can damage human cells and animal lung tissue, causing respiratory issues and other health problems.

Fireworks are a source of microplastic pollution in water
Fireworks are a major source of entertainment for many, but they also contribute to microplastic pollution in water. Fireworks release a host of contaminants that affect air quality and can have severe ecological consequences.
A study by the University of East London (UEL) examined the impact of the UK's New Year's Eve fireworks display on the River Thames and surrounding waterways. The research, led by Ria Devereux, found a shocking increase in microplastic content in the water samples taken after the fireworks display compared to those taken before. Specifically, a 1000% increase in microplastics was observed in the water just six hours after the firework show. Black microplastic fibres were the most common type of plastic observed, and these have been linked to adverse effects on marine life, including delayed growth, oxidative damage, and abnormal behaviour.
Microplastics can absorb harmful toxins from their environment, which can then be transferred into organisms, leading to bioaccumulation and biomagnification within food chains. This not only affects marine life but can also have consequences for human health. Furthermore, particulate matter from fireworks can contaminate water, making it more acidic and causing damage to aquatic ecosystems.
Fireworks contain toxic metals such as lead, titanium, strontium, and copper, which are exposed to high temperatures to create bright colours. These metals are released into the atmosphere during combustion and can then land in water bodies, contributing to water pollution. Perchlorate, a chemical compound often added to fireworks for propulsion, can contaminate water and affect fish development.
To reduce the environmental impact of fireworks, some cities have implemented policies to prohibit or replace fireworks with laser displays. Individual actions, such as spreading awareness and supporting petitions, can also contribute to minimizing the harmful effects of fireworks on the planet.

Particulate matter from fireworks is hazardous to lungs and hearts
Fireworks are a beloved part of celebrations, but they have a detrimental impact on air quality and human health. Fireworks release a host of toxic contaminants that affect air quality and can contribute to climate change, including carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide, and particulate matter.
Particulate matter, or particle pollution, is a combination of minuscule solid and liquid substances found in the air. These particles are known to be hazardous to human health, particularly to the lungs and heart. When fireworks explode, they release gases and tiny particles that can be harmful when inhaled. The particles are so small that they can easily enter the lungs and bloodstream, causing irritation and inflammation.
The health risks associated with particulate matter from fireworks are significant. Inhaling these particles can irritate the lungs, causing coughing and breathing difficulties. It can also worsen existing lung diseases, such as asthma, acute bronchitis, and chronic obstructive pulmonary disease (COPD). Particle pollution has been linked to an increased risk of heart attacks, arrhythmias, stroke, and lung cancer. Even healthy adults can experience adverse effects, with studies showing increased prevalence of chronic cough, phlegm, and breathlessness in adults exposed to high levels of particulate matter.
Certain groups are especially vulnerable to the effects of particulate matter from fireworks. Children, older adults, pregnant individuals, and people with pre-existing lung or heart conditions are at higher risk of experiencing health issues due to their exposure. Given these risks, it is crucial to take precautions to minimize exposure to firework smoke. This includes staying upwind from firework displays, viewing fireworks from a distance, or staying indoors with closed windows during firework shows.
Communities are increasingly exploring alternative ways to celebrate without the use of fireworks. Drones and laser shows offer exciting and innovative options that reduce air pollution, fire hazards, and noise pollution, making them safer and more inclusive for everyone.
