Fireworks' Air Pollution: A Sparkling Display's Dark Secret

Fireworks are a beloved tradition in many countries, but they contribute to air pollution and climate change. Fireworks release toxic atmospheric pollutants, including carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide, and particulate matter. These pollutants affect air quality and can have negative impacts on human and animal health, with vulnerable groups such as children, the elderly, and those with respiratory or cardiac conditions being particularly at risk. Some countries have implemented policies to reduce the environmental impact of fireworks, while cities like Salt Lake City in the United States have started substituting fireworks with lasers during celebrations to mitigate their environmental footprint.

Fireworks release toxic atmospheric pollutants, including carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide, and particulate matter

Fireworks are a well-loved form of entertainment, but they do come with a cost to the environment and human health. Fireworks contain a mixture of chemicals that, when burned, undergo combustion—a chemical reaction that releases toxic atmospheric pollutants. These toxic pollutants include carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide, and particulate matter.

Carbon dioxide (CO2) is released during the combustion of fireworks and contributes to climate change. While carbon dioxide itself is not directly harmful to human health, its presence in the atmosphere can indirectly affect human health by influencing climate patterns and air quality. Carbon monoxide (CO), on the other hand, is a highly toxic gas that can cause serious health issues, including headaches, dizziness, and even death in high concentrations. It is produced during incomplete combustion, where there is insufficient oxygen to fully react with carbon-containing compounds.

Nitrogen and sulphur are also key components of fireworks, responsible for creating the vibrant colours and special effects that delight audiences. However, these chemicals can form nitric and sulphuric acids upon reaction with oxygen, which are extremely harmful to the lungs. During and after fireworks displays, the concentration of these fine particles (known as PM2.5) can spike, posing risks especially to children, the elderly, and individuals with respiratory or cardiac conditions.

Particulate matter, or particle pollution, refers to the minuscule solid and liquid substances released by fireworks that linger in the air. These particles are considered among the most hazardous air pollutants due to their ability to infiltrate people's lungs and cardiovascular systems, causing short- and long-term health issues. The use of fireworks during Diwali in India, for example, has resulted in a significant increase in particulate matter, with cities like Delhi experiencing hazardous levels of air pollution.

As awareness of the environmental and health impacts of fireworks grows, efforts are being made to reduce their negative consequences. Some countries and cities have implemented policies to mitigate these effects, such as substituting traditional fireworks with laser displays or drones, as seen in Salt Lake City, Utah, during the Fourth of July celebrations. These alternatives maintain the spectacle while reducing air pollution and the risk of wildfires.

Fireworks are made up of metallic compounds such as barium, aluminium, copper, and strontium, which can negatively impact human and animal health

Fireworks are a significant source of air pollution, releasing a host of contaminants that affect air quality and contribute to climate change. These include carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide, and particulate matter. The combustion of fireworks releases fine particles, heavy metals, and chemical compounds into the air, negatively impacting human and animal health.

Fireworks are made up of metallic compounds such as barium, aluminium, copper, and strontium, which are responsible for their vibrant colours. When introduced into pyrotechnic compositions and ignited, these metals emit a range of hues, from vibrant reds to intense greens and bright whites. However, these same particles, combined with other compounds, can have detrimental effects on human and animal health.

Barium, for example, can contribute to creating bright white bursts when combined with other compounds. However, exposure to barium can lead to health issues such as muscle weakness, joint pain, and cardiovascular problems. Strontium, known for producing red colours in fireworks, can also have adverse effects on human health, including bone pain, rashes, and, in extreme cases, cardiac arrest. Copper, which creates the blue colour in fireworks, can cause gastrointestinal issues, liver damage, and neurological problems if ingested in large amounts. While the amount of copper in fireworks may not be enough to cause direct harm, its presence in the environment can have cumulative effects, especially in aquatic ecosystems.

In addition to the metallic compounds, fireworks also release other harmful substances such as black powder (saltpeter, charcoal, and sulfur), potassium perchlorate, and dust. These substances can irritate the respiratory system, aggravate lung diseases, and increase the susceptibility to respiratory infections. Individuals with pre-existing respiratory or cardiac conditions are particularly vulnerable to the effects of fireworks smoke, with short-term exposures linked to asthma, acute bronchitis, and heart attacks.

The impact of fireworks on animal health is also significant. The loud noises and bright lights can cause stress, disorientation, and fleeing reactions in animals, especially birds. Fireworks can also leave behind hazardous debris, such as shells and heavy metals, which animals may accidentally ingest, leading to illnesses or even death.

Fireworks contribute to particle pollution, which is considered the most hazardous form of air pollution due to its effects on people's lungs and hearts

Fireworks are a well-known source of entertainment, often associated with celebrations and festivities. However, the colourful displays have a less-known darker side: they contribute significantly to particle pollution, which is considered the most hazardous form of air pollution.

The combustion of fireworks produces a range of toxic atmospheric pollutants, including carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide, and particulate matter. This particulate matter, or PM, is a combination of minuscule solid and liquid substances that can remain suspended in the air. The harmful particles, especially the fine particles known as PM2.5, can be inhaled and pose a severe risk to human health, particularly to the lungs and heart.

During fireworks displays, the concentration of these fine particles in the air can spike to extremely high levels. In India, during the festival of Diwali, the use of fireworks has been associated with a significant increase in PM levels, with certain cities experiencing a 35-fold rise in PM2.5 concentrations compared to normal days. Similarly, in Wisconsin, spikes in PM2.5 levels have been monitored during and after fireworks displays, with the smoke dissipating within a few hours but potentially leaving lingering health effects.

The health effects of inhaling these toxic particles can be severe, especially for vulnerable individuals such as children, the elderly, and those with respiratory or cardiac conditions. Short-term exposure to fireworks smoke can aggravate lung diseases, trigger asthma and acute bronchitis, and increase susceptibility to respiratory infections. For people with heart disease, the smoke has been linked to heart attacks and arrhythmias.

To mitigate the environmental and health impacts of fireworks, some communities and countries are exploring alternative celebrations. For example, Salt Lake City in Utah has started incorporating lasers into their Fourth of July celebrations, reducing air pollution while maintaining the spectacle.

Fireworks displays produce high concentrations of smoke, which can have negative health effects, especially for children, the elderly, and those with respiratory or cardiac conditions

Fireworks are a well-loved form of entertainment, but they have a detrimental impact on the environment and human health. Fireworks displays produce high concentrations of smoke, which can have negative health effects, especially for vulnerable groups such as children, the elderly, and those with respiratory or cardiac conditions.

The smoke from fireworks contains a range of toxic chemicals, including carbon dioxide, carbon monoxide, nitrogen, sulfur dioxide, and particulate matter. These pollutants are released into the atmosphere during combustion, the chemical reaction that occurs when fireworks burn and are exposed to oxygen. The vivid colours in fireworks, which are created using metallic compounds, contribute to the release of these toxic substances. For example, blue colours come from copper, green from barium, and red from strontium.

Particulate matter, a combination of minuscule solid and liquid substances, is considered one of the most hazardous air pollutants. These fine particles, known as PM2.5, can be inhaled and affect people's lungs and hearts. During the Diwali festival in India, a celebration marked by extensive firework displays, cities are covered in a toxic haze, with particulate matter increasing up to 35 times compared to normal days. This toxic haze has significant health implications, especially for those with pre-existing health conditions.

The smoke and pollutants released by fireworks can have both short-term and long-term health consequences. Short-term exposures can aggravate lung diseases, trigger asthma and acute bronchitis, and increase susceptibility to respiratory infections. For individuals with heart disease, the smoke from fireworks has been linked to an increased risk of heart attacks and arrhythmias. Even after the smoke dissipates, individuals may continue to experience lingering health effects.

To mitigate the environmental and health impacts of fireworks, some communities and countries are exploring alternative options. Drone and laser displays, such as those used in the 2020 Tokyo Olympics and in Salt Lake City, Utah, during the Fourth of July celebrations, provide similar visual spectacles without increasing air pollution or the risk of wildfires. These alternatives are part of a growing movement to reduce the harmful effects of fireworks and raise awareness about their impact on the planet.

Some countries and cities have implemented policies to reduce the environmental impact of fireworks, such as substituting them with lasers during celebrations

Fireworks are a major source of air pollution, releasing toxic atmospheric pollutants such as carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide, and particulate matter. These contaminants can affect air quality, cause respiratory and cardiovascular issues, and contribute to climate change. The issue is particularly prominent during celebrations like Diwali in India, where firework usage results in a significant increase in particulate matter, creating a hazardous toxic haze.

Recognizing the environmental impact of fireworks, some countries and cities have implemented policies to reduce their negative effects. For example, several towns in the United States have started using lasers and drones as substitutes during Fourth of July celebrations. Lebanon, New Hampshire, opted for a laser light show for the 2024 Fourth of July celebrations, while cities like Tigard, Lake Oswego, Oregon City, and Wilsonville in Oregon also chose laser and drone displays over traditional fireworks. These technological alternatives provide a visually captivating experience while reducing the environmental damage caused by fireworks.

Salt Lake City in Utah has also been proactive in mitigating the impact of fireworks by incorporating lasers into their Fourth of July celebrations. This approach not only maintains the spectacle of traditional fireworks but also contributes to a greener environment by reducing air pollution and the risk of wildfires. The shift towards lasers and drones as replacements for fireworks is gaining traction, with cities in California, Utah, and Colorado embracing these eco-friendly alternatives.

While some may argue that drone and laser displays lack the impressive impact of traditional fireworks, they offer a less disruptive and more sustainable option. The use of drones eliminates the smoke and air pollutants associated with fireworks, making celebrations more environmentally friendly and pet-friendly. The cost of drone shows has also become more competitive, with some companies offering packages that are comparable in price to traditional fireworks displays. As communities prioritize sustainability and explore ways to reduce their carbon footprint, the adoption of lasers and drones as substitutes for fireworks is likely to become an increasingly popular choice for celebrations.
