Crackers' Air Pollution: Harmful Effects And Solutions

Firecrackers are a source of air pollution, particularly in cities like Delhi, which is one of the world's most polluted cities, especially during the winter months of October to January. The burning of firecrackers during the religious festival of Diwali causes a significant increase in air pollution, with a recent report revealing an 875% surge in some regions of India. The crackers contain toxic gases and chemical compounds, such as nitrous oxide, which can linger in the air and contribute to global warming and respiratory issues. While firecrackers are not the leading cause of pollution, they add to an already problematic situation, affecting vulnerable individuals with pre-existing health conditions and disturbing wildlife.

Firecrackers release toxic gases and chemicals

Firecrackers are a source of air pollution, particularly in cities that are already heavily polluted, such as Delhi. The burning of firecrackers releases toxic gases and chemicals into the atmosphere, which can have detrimental effects on both human health and the environment.

Firecrackers contain toxic gases and chemical compounds, such as nitrous oxide, that are activated when they come into contact with the air. These toxic substances can linger in the air for an extended period, especially in the absence of heavy rain or strong winds. The release of these chemicals contributes to a rapid increase in particulate matter, including PM2.5 and PM10, which are fine particles that can penetrate deep into the lungs and bloodstream, causing severe respiratory issues and other health problems.

The combustion process of firecrackers also produces carbon dioxide and heat, leading to a rise in temperature and an increase in global warming. Additionally, firecrackers introduce heavy metals like aluminium, manganese, and cadmium into the atmosphere, posing long-term respiratory risks even after the smoke has cleared.

Furthermore, firecrackers contain chemicals that contribute to their explosive properties and vibrant colours. These include potassium nitrate, which acts as an oxidizer; sulfur, which aids in ignition and burning; charcoal, which serves as fuel; and various metal compounds that produce different colours, such as barium nitrate for green and strontium nitrate for red. When burned, these chemicals release additional toxic fumes, exacerbating air pollution and posing serious health hazards.

While firecrackers alone may not be the leading cause of pollution, they significantly add to the problem, especially during festivals like Diwali, when their use is concentrated. The cumulative effect of firecracker emissions, along with other sources of pollution, can lead to hazardous levels of pollutants, affecting the health of residents and causing respiratory and cardiac issues.

They cause noise pollution

Fireworks and crackers are a significant source of noise pollution, which can have a range of detrimental effects on both human and animal health. The loud noises produced by crackers can cause hearing loss in people who are exposed to them. Research has also shown that the noise can cause stress and anxiety in both humans and animals, with animals often becoming scared and seeking out safe places. The noise from crackers can also alter animal behaviour and has been linked to wildlife deaths.

In addition, the loud noises can be particularly dangerous for the elderly, with reports of heart attacks occurring as a result of the loud sounds. There is also some suggestion that consistent exposure to loud noises from crackers during pregnancy may cause problems for the baby, although this has not been proven.

The noise pollution caused by crackers can also have an impact on the environment. The loud sounds can disturb wildlife, leading to changes in animal behaviour and even death in some cases. This type of pollution can also affect humans, with reports of increased stress levels and anxiety caused by the noise.

While the tradition of setting off crackers during celebrations such as Diwali is deeply ingrained in many cultures, it is important to consider the potential health and environmental consequences. Eco-friendly alternatives, such as LED lights and silent fireworks, can help reduce noise pollution and minimise the harmful effects on the environment and human health.

They increase the risk of fire accidents

Fireworks and crackers are a source of joy and excitement for many, especially during festivals and celebrations. However, it is crucial to understand the adverse effects of crackers on the environment and human health. Crackers contain toxic gases and chemical compounds that are released into the atmosphere, contributing to air pollution and causing a range of health issues. One of the significant concerns associated with crackers is the increased risk of fire accidents.

Fire accidents are a common occurrence during festive seasons, especially in densely populated areas like markets. The sparks and flames produced by crackers can easily ignite flammable materials, leading to devastating fires. Even a small spark from a cracker can set off a chain reaction, resulting in significant damage and endangering lives. The risk of fire accidents is heightened during celebrations when a large number of crackers are set off in a short period.

The chemicals and substances used in the manufacture of crackers further exacerbate the risk of fire accidents. Crackers contain substances like sulphur, magnesium, nitrogen dioxide, and even lead and lithium in larger ones. These substances are highly flammable and can fuel the intensity of a fire. Additionally, the presence of aluminium and sulphur nitrate enables crackers to produce loud sounds, but these same components can also contribute to the spread of fire. The combination of flammable substances and loud explosions increases the likelihood of fire accidents, making it a significant concern during celebrations involving crackers.

Furthermore, the residue and dust left behind by crackers can also increase the risk of fire accidents. After firing, the dust and chemical pollutants containing substances like sulphur, zinc, copper, and sodium settle in exposed areas. These pollutants not only harm the environment and human health but can also act as fuel for potential fires. The accumulation of this residue can create hazardous conditions, especially in crowded areas or places with inadequate ventilation.

The impact of fire accidents extends beyond the immediate damage caused by the flames. The smoke and fumes released during a fire can irritate the lungs and worsen respiratory conditions for those exposed. Additionally, fire accidents can lead to power outages and infrastructure damage, affecting essential services and the overall functionality of a community. It is crucial to recognize the heightened risk of fire accidents associated with crackers and take preventive measures to ensure the safety of individuals and property during celebrations.

They contribute to global warming

Fireworks and crackers are a source of joy and celebration for many, but they also have a negative impact on the environment. While crackers may not be the leading cause of pollution, they do contribute to global warming.

The combustion of crackers releases a significant amount of pollutants into the atmosphere. These include particulate matter, sulfur dioxide, carbon monoxide, and various heavy metals. These chemicals, when burned, release toxic fumes and gases that contribute to air pollution and pose serious health risks. The release of fine particulate matter (PM2.5 and PM10) is particularly concerning, as these particles can penetrate deep into the lungs and bloodstream, causing severe respiratory and cardiovascular issues.

The toxic gases and chemical compounds in crackers, such as nitrous oxide, can linger in the air for an extended period, especially in the absence of heavy rain or strong winds. This contributes to an increase in the concentration of greenhouse gases, which trap heat and lead to a rise in the Earth's temperature, causing global warming.

The impact of crackers on global warming is further exacerbated by the presence of other pollutants in the atmosphere. For example, in highly populated cities like Delhi, the air quality is already compromised due to emissions from household combustion devices, motor vehicles, industrial facilities, and forest fires. The additional pollutants released by crackers intensify the problem, leading to a more significant increase in temperature and contributing to global warming.

Furthermore, the noise pollution caused by crackers can also have indirect effects on global warming. The loud noise can cause stress and anxiety in humans, potentially leading to increased energy consumption and a higher carbon footprint. Additionally, the disturbance to wildlife can disrupt natural ecosystems and impact their ability to mitigate the effects of climate change.
