Fireworks And Fun: Pollution's Impact On The Fourth Of July

Fireworks are a major part of Fourth of July celebrations in the US, but they also cause a significant increase in air pollution. The Environmental Protection Agency (EPA) reports a marked increase in air pollution levels during the celebrations, with fireworks releasing particulate matter (PM) and various pollutants into the atmosphere. These pollutants include heavy metals, perchlorates, and other chemicals that can harm both the environment and human health. The smoke generated by fireworks can cause air quality to plummet in the days that follow, and they can also trigger wildfires that lead to far longer-lasting and widespread air pollution.

Fireworks cause air pollution

Fireworks release particulate matter (PM) and various pollutants into the atmosphere. These pollutants include heavy metals, perchlorates, and other chemicals that can harm both the environment and human health. The bright colours and spectacular displays of fireworks come from metals such as copper, strontium, and barium, which, when burned, release toxic compounds. These compounds can contaminate drinking water supplies and contribute to broader marine pollution, impacting local wildlife and the health of marine food chains.

Fireworks can also trigger wildfires that lead to far longer-lasting and widespread air pollution. An analysis of wildfires on federal land in the US over a 37-year period found that two-thirds of the fires attributed to fireworks occurred in the two-week period around the 4th of July. Large wildfires can send pollution high into the atmosphere, where it can spread over thousands of miles and become more toxic.

The loud explosions of fireworks can also disturb wildlife, causing stress and disorientation. Pets and other animals can suffer from anxiety and hearing damage due to the intense noise. In addition, the celebrations generate substantial waste, from discarded fireworks casings to food packaging and single-use plastics. Effective waste management and recycling programs are essential to mitigate this issue.

Fireworks can trigger wildfires

Fireworks are a major part of the 4th of July celebrations, but they can cause a lot of pollution. The captivating and colourful fireworks show generates around 94.3 kilotons of carbon dioxide emissions annually. The Environmental Protection Agency (EPA) reports a marked increase in air pollution levels during the celebrations. Fireworks are a major contributor, releasing particulate matter (PM) and various pollutants into the atmosphere. These pollutants include heavy metals, perchlorates, and other chemicals that can harm both the environment and human health.

Each year, Americans set off nearly 300 million lbs (136,000 tonnes) of fireworks – nearly one pound for every person living in America. In 2022, that figure jumped to more than 460 million pounds (209,000 tonnes) of fireworks. That's a lot of explosions and sparkles – but also a lot of smoke and waste, which may not only harm the planet, but also potentially the lungs of people nearby too.

Fireworks can also trigger wildfires that lead to far longer-lasting and more widespread air pollution. One analysis of wildfires on federal land in the US over a 37-year period from 1980 found that 11,294 of nearly 600,000 fires over that period could be attributed to fireworks. Two-thirds of these occurred in the two-week period around 4 July. Large wildfires can send pollution high into the atmosphere, causing it to spread over thousands of miles, during which time it can become more toxic.

The contamination can affect drinking water supplies and contribute to broader marine pollution. This persistent pollution not only impacts local wildlife but also poses risks to the health of marine food chains.

Fireworks can disturb wildlife

The 4th of July celebrations in the US involve millions of fireworks being set off, which cause air pollution to spike. In 2022, Americans set off more than 460 million pounds (209,000 tonnes) of fireworks. This generates around 94.3 kilotons of carbon dioxide emissions annually and releases particulate matter and various pollutants into the atmosphere. These include heavy metals, perchlorates, and other chemicals that can harm the environment and human health.

The bright colours and spectacular displays of fireworks come from metals such as copper, strontium, and barium, which release toxic compounds when burned. These metals are used to produce the bright colours in fireworks as they burn while cascading back to Earth. The contamination can affect drinking water supplies and contribute to broader marine pollution, impacting local wildlife and posing risks to the health of marine food chains.
