Fireworks' Pollution Problem: How Bad Is It?

Fireworks are a beloved tradition in many countries, but they are not without their environmental impact. Fireworks propel a cocktail of chemicals into the atmosphere, including metallic compounds such as barium and aluminium, which can have negative impacts on both human and animal health. Fireworks also release smoke and gases such as carbon dioxide, carbon monoxide, and nitrogen—greenhouse gases that contribute to climate change. Studies have shown that firework displays can cause a significant increase in air pollutants, with levels of nitric oxide and sulfur dioxide, which are primary contributors to acid rain, spiking during celebrations. With fireworks causing a toxic haze to cover cities, it is important to consider the environmental and health consequences of their use.

Fireworks release high levels of pollution, including heavy metals, into the air

Fireworks are a major source of air pollution, releasing a range of toxic chemicals and heavy metals into the atmosphere. The combustion of fireworks produces a host of contaminants that affect air quality and contribute to climate change. These include carbon dioxide, carbon monoxide, nitrogen oxides, sulphur dioxide, and particulate matter. Fireworks also release heavy metals such as strontium, vanadium, potassium, titanium, barium, copper, lead, magnesium, aluminium, and zinc. These metals can remain in the atmosphere for extended periods, causing long-range transport of these pollutants.

A study in London found increased levels of gas-phase pollutants, including nitric oxide and sulphur dioxide, following fireworks displays during two major festivals. These pollutants are primary contributors to acid rain and climate change, and they irritate the lungs and throat. The study also detected elevated concentrations of fine particulates and trace amounts of heavy metals, with strontium levels increasing 120 times and magnesium levels increasing 22 times within an hour of the fireworks displays.

The metal salts and explosives in fireworks undergo a chemical reaction during combustion, releasing smoke and gases. These metal salts do not burn up completely and persist as metal atoms in the environment. They can contaminate the air, water, and soil, leading to short- and long-term health effects when inhaled or ingested. The health impacts range from vomiting, diarrhoea, and asthma attacks to more severe conditions like kidney disease, cardiotoxic effects, and various cancers.

Fireworks also contribute to microplastic pollution in water. A study of the River Thames in England found a shocking 1000% increase in microplastic content following the New Year's Eve firework show. Additionally, the bright colours in fireworks originate from metallic compounds such as barium and aluminium, which can have detrimental effects on both human and animal health. Fireworks also negatively impact wildlife, causing stress and disorientation due to the loud noises and bright lights.

Fireworks are also responsible for water pollution, contaminating local watersheds

Fireworks are a major source of water pollution, contaminating local watersheds and posing a significant threat to the environment and public health. The heavy metals and chemicals released during combustion can have severe ecological and health consequences.

One of the primary ways fireworks contribute to water pollution is through the release of perchlorate, a chemical compound that acts as an oxidiser, facilitating the upward propulsion of fireworks. Perchlorate is highly persistent in the environment and can contaminate soil and water sources. It has been detected in elevated concentrations in soil and water samples following fireworks displays. This chemical can disrupt the normal function of the thyroid gland and affect fish development, posing risks to aquatic ecosystems and potentially impacting the health of humans and wildlife that come into contact with contaminated water sources.

Particulate matter, or PM, is another significant pollutant released by fireworks that contributes to water pollution. These minuscule solid and liquid particles can contaminate surface water, making it more acidic and severely impacting aquatic ecosystems. Moreover, PM can remain suspended in the atmosphere for extended periods, leading to long-range transport of contaminants and subsequent deposition into water bodies through rainfall or atmospheric deposition. This can result in the accumulation of toxic pollutants in local watersheds, further exacerbating water pollution.

Fireworks also release metal salts during combustion, which do not burn up completely. These metal atoms become aerosols that can contaminate water sources. Heavy metals, such as strontium, vanadium, lead, and zinc, are among the pollutants traced in fireworks emissions. When washed out of the air by rainfall, these metals accumulate in local watersheds, leading to increased water pollution. The presence of these toxic metals in water bodies can have detrimental effects on aquatic life and the overall health of the ecosystem.

Additionally, fireworks contribute to microplastic pollution in water. The combustion of fireworks can produce plastic particles smaller than 5mm in diameter, which are then released into the environment. A notable example is the significant increase in microplastic content observed in the River Thames after the New Year's Eve firework show. The presence of microplastics in water bodies has become an emerging environmental concern due to their persistence and potential ecological impacts.

Fireworks contribute to climate change by releasing greenhouse gases

Fireworks are a major source of air pollution, releasing a host of toxic contaminants that affect air quality and contribute to climate change. Fireworks introduce 42% more pollutants into the air than usual on a typical day.

The metal salts and explosives in fireworks undergo a chemical reaction during combustion, releasing these harmful gases. These metal salts do not burn up completely, leaving metal atoms that become aerosols. These aerosols, containing heavy metals such as strontium, barium, and lead, can poison the air, water, and soil. The release of these metals during fireworks displays has been linked to increased levels of these toxins in the environment, causing short- and long-term health issues for humans and wildlife.

Furthermore, fireworks emit fine particulate matter, which is considered the most hazardous air pollutant. These particles, with a diameter of 2.5 micrometers or less, can easily enter the lungs and bloodstream, causing respiratory and cardiovascular issues. Fireworks also release perchlorates, which can contaminate water sources and disrupt the thyroid's function, affecting both human and animal health.

The environmental impact of fireworks is significant, and they contribute to climate change through the release of greenhouse gases and other toxic pollutants. While they provide temporary entertainment, the negative consequences for the planet and human well-being are long-lasting.

Fireworks cause soil pollution, with metals poisoning the earth

Fireworks are a major source of pollution, and their impact on the environment is significant. While the bright lights and colours of fireworks are visually appealing, they come at a cost to the planet. Fireworks cause soil pollution, with metals poisoning the earth, and this has a detrimental effect on the health of humans, wildlife, and the environment.

Fireworks contain metal salts, and when they explode, these metals do not burn up. Instead, they remain as metal atoms, which are released into the atmosphere as aerosols. These metals, including strontium, vanadium, potassium, titanium, barium, copper, lead, magnesium, aluminium, and zinc, are toxic to the environment and harmful to human health. They can cause a range of short- and long-term health issues, from vomiting and diarrhoea to asthma attacks, kidney disease, cardiotoxic effects, and even cancer.

The impact of fireworks on soil pollution is significant. When metal particles are released into the air, they are eventually washed out by rainfall, accumulating in and polluting local watersheds. This pollution affects the quality of soil, groundwater, and plants, with potential consequences for the entire food chain. Studies have shown that foliage dust samples collected before and after fireworks displays contain higher levels of these toxic metals, indicating their presence in the environment even after the fireworks have faded.

In addition to soil pollution, fireworks also contribute to air pollution and water pollution. The metal particles released during explosions are small enough to be easily inhaled, posing health risks to sensitive individuals and increasing the concentration of metal emissions in the air. Fireworks also release highly toxic gases, including nitrogen, carbon dioxide, and carbon monoxide, which contribute to climate change and irritate the lungs and throat.

The environmental impact of fireworks is often overlooked, but it is important to recognize the damage they can cause. With increased awareness, we can make informed choices about our entertainment and celebration methods, opting for environmentally friendly alternatives that reduce the harmful effects of fireworks on the planet and human health.
