Firecrackers And Air Pollution: A Harmful Tradition

Fireworks and firecrackers are a major source of air pollution. They release harmful gases and particles into the atmosphere, including sulfur dioxide, carbon dioxide, carbon monoxide, nitrogen, nitric oxide, and particulate matter. These pollutants can have significant short-term and long-term health effects, especially on vulnerable groups such as children, the elderly, and people with respiratory or cardiovascular diseases. During cultural festivals like Diwali in India, firecrackers contribute to a rapid increase in atmospheric pollution and a degradation of air quality, causing critical health issues. While firecrackers are not the sole cause of air pollution, they add an obvious layer to an already problematic situation, and their impact on human health and the environment cannot be ignored.

Firecrackers release harmful gases and metals

Firecrackers are a significant contributor to air pollution, particularly during festivals like Diwali, when firecrackers are burnt by almost every household for 3 days. The burning of firecrackers releases a variety of harmful gases and metals.

Firecrackers release gases such as carbon dioxide, carbon monoxide, nitrogen, and sulphur dioxide, which are very harmful to our lungs. These gases can cause serious health problems, especially for those with existing respiratory issues. Carbon monoxide, for example, can elevate to dangerous levels during firework displays, affecting air visibility and increasing the atmospheric heat content. Sulphur dioxide, a byproduct of firecracker combustion, has been recorded at levels 200 times above the safety limits set by the World Health Organization.

The smoke released by firecrackers also contains harmful metals, including aluminum, manganese, and cadmium. Some illegal fireworks even contain lead, which is extremely dangerous and can cause long-term damage. These metals are released into the air and can be inhaled, posing serious health risks to those exposed.

The particulate matter (PM) produced by firecrackers is another major concern. PM refers to the tiny particles released in firework smoke, which can be harmful when inhaled. These particles can irritate the lungs, causing coughing and triggering asthma attacks. They can also have long-term health effects, particularly for vulnerable groups such as children, the elderly, and those with underlying health conditions.

The pollution caused by firecrackers not only affects human health but also has environmental implications. The release of these harmful gases and metals contributes to atmospheric pollution and the degradation of air quality, affecting cities and the planet as a whole.

Firecrackers cause an increase in PM2.5 levels

Firecrackers are a significant contributor to air pollution, particularly in densely populated areas. While they are not the sole cause of poor air quality, their use can lead to a rapid increase in particulate matter (PM) concentrations, specifically PM2.5 levels, which pose a serious health risk.

PM2.5 refers to particulate matter with a diameter of less than 2.5 microns. These fine particles can remain suspended in the air for extended periods and can be inhaled deep into the respiratory tract, causing respiratory and cardiovascular issues. During the burning of firecrackers, various organic and inorganic compounds are released into the atmosphere, including carbon, ammonium, potassium, and heavy metals.

Studies have shown that firecrackers significantly increase PM2.5 levels. For example, in the Indian city of New Delhi, firecrackers during the Diwali festival have been found to contribute to a nearly 25% increase in PM2.5 concentration annually. Similarly, in the United States, Independence Day fireworks result in elevated PM2.5 levels, with increases of up to 370% observed at sites adjacent to fireworks displays.

The impact of firecrackers on PM2.5 levels is influenced by various factors, including the type of firecracker, the duration of burning, and the proximity of the measurements to the burning source. For instance, snake tablets and garlands of multiple crackers tend to produce higher PM2.5 levels compared to sparklers and flower pots. Additionally, the accumulation of firecrackers' emissions in densely populated areas can have a more pronounced effect on air quality.

While firecrackers may bring joy to some people during celebrations, their impact on PM2.5 levels and overall air quality cannot be overlooked. The increase in PM2.5 concentrations caused by firecrackers can have detrimental effects on human health, particularly for individuals with respiratory conditions, the elderly, and children. Therefore, it is essential to consider the potential consequences and explore alternative ways to celebrate while minimizing the impact on the environment and public health.

Firecrackers are particularly dangerous for vulnerable groups

Firecrackers are a significant source of air pollution, particularly in densely populated cities. The smoke released from firecrackers contains tiny particles known as particulate matter (PM), which can be extremely harmful when inhaled. These particles can irritate the lungs, causing coughing and triggering asthma attacks, and have been linked to various adverse health effects, including lung cancer and premature death. The pollution caused by firecrackers can have severe consequences, leading to excess premature deaths and emergency admissions.

While firecrackers pose risks to everyone exposed to their smoke, certain vulnerable groups are especially susceptible to the dangers. Children, for instance, are far more vulnerable to the harmful effects of firecracker pollution. Their developing lungs and smaller bodies make them more susceptible to the impact of air pollutants. Prolonged exposure to firecracker smoke can have immediate and long-term consequences on children's health, affecting their respiratory and circulatory systems and increasing their cancer risk.

Older adults are another vulnerable group. As people age, their bodies may become weaker, and their respiratory systems may become more fragile. Exposure to firecracker pollution can exacerbate existing health conditions and increase the risk of respiratory and cardiovascular complications in the elderly. For those with pre-existing medical conditions, such as lung or heart disease, extreme exposure to firecracker pollution could be particularly detrimental, potentially leading to emergency room visits.

In addition to children and the elderly, individuals with pre-existing respiratory conditions, such as asthma, are at heightened risk. The particulate matter and gases released from firecrackers can trigger asthma attacks and worsen lung diseases. For people with weak respiratory systems, firecracker pollution can significantly impact their quality of life and pose serious health risks.

Furthermore, firecrackers can also affect pregnant women. Exposure to air pollution during pregnancy has been associated with adverse birth outcomes and an increased risk of developmental issues in children. The pollutants and toxins released from firecrackers can have detrimental effects on both the mother and the developing fetus, underscoring the vulnerability of this group.

Firecrackers can start wildfires, worsening air pollution

Fireworks and firecrackers are a source of air pollution and can cause wildfires, which in turn worsen air pollution. Fireworks release smoke filled with tiny particles that are harmful when inhaled. These particles are known as particulate matter (PM) and include PM10, fine particles (PM <2.5 μm in MMAD [PM2.5]), ultrafine particles (MMAD ≤100 nm), and nanoparticles (MMAD ≤50 nm).

PM2.5 particles, in particular, have been associated with various short-term and long-term respiratory health hazards. They have a larger surface-to-volume ratio, a longer residence time in the atmosphere, and carry a higher proportion of organic compounds compared to larger particles. These particles can reach the distal portions of the lungs and generate relatively more reactive oxygen species, making them more harmful.

The burning of firecrackers can rapidly increase PM levels, leading to critical health issues. Studies have shown that during festivals like Diwali, when firecrackers are extensively used, there is a significant increase in PM2.5 concentration levels. For example, in New Delhi, burning firecrackers may increase PM2.5 concentration levels by up to 25% annually during Diwali.

Additionally, firecrackers release gases such as sulfur dioxide, carbon dioxide, and carbon monoxide, which are detrimental to lung health. The smoke from firecrackers also releases harmful metals into the air, including aluminum, manganese, cadmium, and even lead in some cases. These metals can have long-term detrimental effects on both humans and the environment.

The impact of firecrackers on air pollution is particularly notable in densely populated areas, such as Delhi, one of the most polluted cities globally. The combination of firecrackers, vehicle emissions, and agricultural stubble burning during festivals like Diwali significantly degrades air quality.

To mitigate the impact of firecrackers on air pollution, some governments have implemented bans or restrictions on their production, sale, and use. However, enforcement of these bans has been challenging, and there are ongoing debates about balancing environmental concerns with cultural and religious traditions.

Firecrackers cause noise pollution, affecting animals

Firecrackers have become a common feature of celebrations and special events, with people bursting them at weddings, festivals like Diwali, sports events, and product launches. The festival of Diwali, in particular, sees people bursting firecrackers endlessly, contributing to both air and noise pollution.

While the debate continues on whether firecrackers are the leading cause of pollution, there is no denying that they do add a layer of pollution to an already critical situation. The near-ground firecracker burning during Diwali is responsible for atmospheric pollution and a rapid increase in particular matter (PMs), which not only reduces visual range but also leads to critical health issues. Studies have shown a substantial increase in PM 2.5 levels, which is a serious health hazard for humans and animals alike.

The loud noises from firecrackers cause severe noise pollution, affecting animals with their sensitive hearing. The continuous sounds scare animals, and the bright lights from fireworks can disorient and even blind birds. Some people even tie firecrackers to the tails of stray animals, causing them immense distress. The noise levels can lead to deafness in some animals and cause trauma, with the effects of noise pollution not restricted to just the duration of the firecrackers but lasting much longer.

The impact of firecrackers on animals is often overlooked, and while the tradition of bursting firecrackers during celebrations may bring joy to some, it is important to consider the distress and harm it causes to animals and the environment. The government has a responsibility to enforce bans and regulations on the production and sale of firecrackers to mitigate the issue, but individuals also need to be mindful of the consequences of their actions and find alternative ways to celebrate without causing harm to others.
