Fireworks And Air Pollution: A Harmful Mix?

Fireworks are a source of entertainment for many, but they also contribute to air pollution. Fireworks generate large amounts of smoke, which can negatively impact air quality. The smoke from fireworks is made up of coarse and fine particles, including particulate matter known as PM2.5, which can have adverse effects on human health. Fireworks also release other pollutants such as sulphur dioxide, carbon dioxide, and carbon monoxide, which can be harmful to both people and the environment. While the impact of fireworks on air quality is short-lived and localised, it is important to consider their environmental and health impacts, especially when they are used extensively during celebrations and can affect vulnerable individuals such as children, the elderly, and those with respiratory or cardiac conditions.

Fireworks release harmful chemicals into the atmosphere, including carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide, and particulate matter

Fireworks are a major part of celebrations and festivals across the world, but they also release harmful chemicals into the atmosphere, including carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide, and particulate matter. These chemicals have a detrimental impact on the environment and human health.

The combustion of fireworks produces toxic atmospheric pollutants. Fireworks are made from black powder or gunpowder, which is a mixture of potassium nitrate, charcoal, and sulphur. When this mixture is ignited, it creates a loud, gaseous, and hot chemical reaction—an explosion. To create colourful explosions, mineral elements are added. These explosions release a host of contaminants that affect air quality and can contribute to climate change.

Carbon dioxide, a well-known greenhouse gas, is released into the atmosphere during firework explosions. Carbon monoxide, a toxic gas that hinders the ability of living organisms to transport oxygen, is another byproduct of firework combustion. Fireworks also release nitrogen and sulphur, which can combine with oxygen to form nitric and sulfuric acids. These acids are particularly harmful to the lungs. Sulphur also contributes to the release of sulphur dioxide during firework explosions.

Particulate matter, or PM, is another significant pollutant released by fireworks. It is a combination of minuscule solid and liquid substances found in the air. PM is considered one of the most hazardous air pollutants due to its impact on the lungs and heart, as well as its ability to cause environmental damage. During firework displays, the concentration of fine particulate matter (PM2.5) can increase significantly, affecting air quality and human health.

The release of these harmful chemicals during firework displays has tangible consequences. In the case of Delhi, India, during the festival of Diwali, the city experienced extremely high levels of particulate matter, with an hourly PM2.5 concentration of 900 μg/m3. This is in stark contrast to the World Health Organization's guidelines, which state that the average concentration of PM2.5 should not exceed 5 μg/m3 per year. Similar increases in particle pollutant concentrations have been observed in other parts of the world, such as central London, during fireworks displays.

Fireworks can cause toxic haze, also known as particle pollution, which is considered the most hazardous air pollutant

Fireworks are a major part of celebrations and festivals across the world, but they have a detrimental impact on the environment. Fireworks are made from black powder or gunpowder, which is a mixture of potassium nitrate, charcoal and sulphur. When this is placed inside a shell and ignited, it creates a loud, gaseous and hot chemical reaction—an explosion. Mineral elements are added to create colour, and other chemicals are added to act as stabilisers and oxidisers.

These chemicals do not simply disappear into thin air. When burned and exposed to oxygen, they undergo combustion, creating short-lived entertainment and toxic atmospheric pollutants. Fireworks release a host of contaminants that affect air quality and can contribute to climate change, including carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide and particulate matter.

Toxic haze, or particle pollution, is created by particulate matter (PM), a combination of minuscule solid and liquid substances found in the air. This is considered the most hazardous air pollutant due to its ability to affect people's lungs and hearts and cause environmental damage. During the festival of Diwali in India, a toxic haze covers cities as around 50,000 tons of fireworks explode. In the case of Delhi in 2017, there were 900 micrograms of fine particles in one cubic metre of air in an hour—far more than the World Health Organization's recommended average concentration of PM2.5, which is 5 micrograms per cubic metre of air in a year.

Particle pollution can have serious health impacts. Fine soot particles have been linked to a range of health problems, including asthma, heart disease and low birth weight. Individuals exposed to high levels of air pollutants have shown an increased prevalence of chronic cough, phlegm and breathlessness, and are therefore at a higher risk of developing asthma, lung cancer and other respiratory diseases. Particle pollution is especially harmful to children, the elderly, and individuals with respiratory or cardiac conditions. Short-term exposure can aggravate lung disease, causing asthma and acute bronchitis, and increasing susceptibility to respiratory infections. In people with heart disease, short-term exposure to firework smoke has been linked to heart attacks and arrhythmias.

Fireworks also release large amounts of smoke, which can negatively impact air quality. In some areas, the concentration of fine particulate pollution known as PM2.5 can be between 1.5 and 10 times higher than normal on the night of a fireworks display and the following day. The smoke from fireworks generally dissipates within a few hours, but individuals may feel lingering health effects.

Fireworks can increase the risk of respiratory problems, such as asthma and acute bronchitis, especially in children, the elderly, and those with pre-existing health conditions

Fireworks are a major part of celebrations and festivals, but the smoke they generate can have a detrimental impact on air quality. Fireworks release large amounts of smoke, which can negatively affect air quality, and they also emit other pollutants that are harder to see. These include carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide, and particulate matter.

The smoke from fireworks is made up of both coarse and fine particles, with the fine particles (known as PM2.5) being of particular concern due to their potential impact on human health. These fine particles can penetrate deep into the lungs and have been linked to a range of respiratory problems, including asthma and acute bronchitis.

Children, the elderly, and individuals with pre-existing health conditions, such as respiratory or cardiac issues, are especially vulnerable to the effects of fireworks smoke. Short-term exposure to fireworks smoke can aggravate lung disease, trigger asthma attacks, and increase the risk of acute bronchitis. The fine particles in the smoke can also make individuals more susceptible to respiratory infections, which can have serious consequences for those with compromised immune systems.

To minimise the health risks associated with fireworks, it is recommended that individuals reduce or avoid the use of personal fireworks, as these tend to concentrate smoke at ground level. Community events with aerial fireworks displays are preferable, as the smoke is released at a higher altitude and has more space to dissipate before reaching people on the ground. For those who are particularly sensitive to smoke, it is advisable to stay indoors during fireworks displays, especially after dark, and to keep windows closed.

Fireworks displays can release large amounts of smoke, which can negatively impact air quality and have potential health effects on nearby individuals

The smoke from fireworks is made up of both coarse and fine particles, including particulate matter known as PM2.5, which can be between 1.5 and 10 times higher than normal after fireworks displays. These fine soot particles have been linked to a range of health problems, including asthma, heart disease, and low birth weight. Individuals exposed to high levels of air pollutants have shown an increased prevalence of chronic cough, phlegm, and breathlessness, and are at a higher risk of developing asthma, lung cancer, and other respiratory diseases.

The impact of fireworks on air quality is particularly noticeable during large celebrations, such as the 4th of July in the US and Diwali in India. During these events, the air pollution can increase significantly, affecting the air quality and the health of those nearby. The brilliant colours in fireworks are created from powdered metallic salts, with copper producing blue, barium producing green, and strontium producing red. The smoke from these metallic salts can be very hard on the lungs, and individuals may feel lingering health effects.

While the smoke from fireworks displays generally dissipates within a few hours, it can have short-term impacts on the health of those nearby, especially children, the elderly, and individuals with respiratory or cardiac conditions. Short-term exposure to fireworks smoke can aggravate lung disease, causing asthma and acute bronchitis, and increasing susceptibility to respiratory infections. For those with heart disease, short-term exposure has been linked to heart attacks and arrhythmias.

To minimise the impacts of fireworks smoke, individuals can reduce or eliminate their use of personal fireworks, which tend to concentrate smoke at ground level. Aerial displays, while producing more smoke, launch fireworks higher above the ground, allowing the smoke to dissipate more completely before reaching people. Individuals who anticipate a health reaction to the intense smoke of fireworks displays are advised to avoid the areas and view the fireworks from a distance or stay indoors.

Fireworks can contribute to climate change by releasing greenhouse gases and other pollutants into the atmosphere

Fireworks are a source of entertainment and celebration, but they also have a significant impact on the environment. Fireworks can contribute to climate change by releasing greenhouse gases and other pollutants into the atmosphere. The combustion of fireworks produces a range of toxic atmospheric pollutants, including carbon dioxide, carbon monoxide, nitrogen, sulphur dioxide, and particulate matter. These emissions have both short-term and long-term effects on air quality and the environment.

During and after fireworks displays, there is a notable spike in the concentration of fine particulate matter, known as PM2.5. These fine soot particles are released into the atmosphere and can have serious health implications. Studies have linked exposure to PM2.5 to an increased risk of asthma, heart disease, and low birth weight. The impact of fireworks on air quality can be particularly pronounced in certain areas, with concentrations of PM2.5 increasing by up to 10 times the normal levels during and after the 4th of July celebrations in the United States.

In addition to particulate matter, fireworks also release heavy metals and toxic chemicals into the atmosphere. Metals such as copper, potassium, barium, chromium, vanadium, and strontium have been found to spike during fireworks displays. These metals are used to create the bright colours and special effects that make fireworks so appealing. However, they pose a significant threat to both human health and the environment. The combustion of fireworks also produces nitrogen and sulfur compounds, which can combine with oxygen to form nitric and sulfuric acids. These acids are particularly harmful to the lungs, causing respiratory issues and aggravating existing lung conditions.

The release of greenhouse gases, such as carbon dioxide, contributes to the overall increase in atmospheric heat content. This, in turn, leads to elevated surface air temperatures and reduced air visibility. Fireworks displays can decrease air visibility by up to 92%, significantly impacting local air quality. The environmental impact of fireworks extends beyond air pollution. Fireworks can also contaminate soil and water sources with perchlorate, a chemical compound used as an oxidizer in fireworks. Perchlorate can affect the function of the thyroid gland in high concentrations and has been found to contaminate soil and water sources near fireworks displays.

Furthermore, fireworks contribute to plastic pollution, particularly in waterways. A study of the River Thames in London found a shocking increase of over 1000% in microplastic content following the New Year's Eve fireworks display. This sudden influx of microplastics can have detrimental effects on the ecology of the river and neighbouring waterways, ultimately impacting the food chain.

While the impact of fireworks on air pollution may be short-lived and localized, it is important to recognize that the release of greenhouse gases and other pollutants contributes to the overall burden of climate change. The celebration and entertainment provided by fireworks come at a cost to the environment and public health. As awareness of the negative impacts of fireworks grows, there is a need for alternative solutions, such as laser shows and drones, that can provide entertainment while reducing emissions and minimizing environmental damage.
