Are Fireworks Bad for the Environment?

Are fireworks bad for the environment? The short answer is yes. Fireworks are a popular way to celebrate holidays and special events, but they come with a price. The chemicals and materials used to create the colorful explosions can have negative effects on the environment.

When fireworks are set off, they release a variety of pollutants into the air, including sulfur dioxide, carbon dioxide, and heavy metals. These pollutants can contribute to air and water pollution, harm wildlife, and even affect human health. In addition, the debris left behind after fireworks displays can litter the environment and encounter it.

While fireworks are undoubtedly fun to watch, it’s important to consider their impact on the environment. By understanding the potential harm caused by fireworks, you can make more informed choices about how to sustainably celebrate holidays like the 4th of July. Whether you choose to forgo fireworks altogether or opt for more environmentally-friendly alternatives, you can help reduce the negative impact that fireworks have on our planet.

Environmental Impact of Fireworks

Fireworks are a common sight during celebrations, but they can have a significant impact on the environment. The chemicals used in fireworks can contribute to air, water, and soil pollution.

Air Pollution

Fireworks release a range of chemicals into the air, including sulfur dioxide, nitrogen oxides, and particulate matter. These chemicals can contribute to air pollution, which can have harmful effects on human health. Exposure to air pollution from fireworks can aggravate lung disease, cause asthma and acute bronchitis, and increase risk of developing respiratory infections, as well as pose a significant risk to those with heart disease (1).

Fireworks can also release heavy metals into the air, such as lead, cadmium, and mercury. These metals can accumulate in the environment and can be harmful to wildlife. In addition, the loud noise produced by fireworks can cause stress and anxiety in animals, including both pets and wildlife.

Water Pollution

Fireworks can also contribute to water pollution. When fireworks are set off over bodies of water, the chemicals can fall into the water and contaminate it. The chemicals can also leach into the soil and groundwater, which can affect the quality of drinking water.

Fireworks can contain perchlorates, which are used as oxidizers to help the fireworks burn. Perchlorates have been known to decrease thyroid hormone production in large quantities and is even used to medically treat overactive thyroid conditions (2). When perchlorates enter the water supply, they can be difficult to remove and can persist in the environment for a long time.

Soil Pollution

Fireworks can also contribute to soil pollution. The chemicals used in fireworks can contaminate the soil, which can affect plant growth and reduce soil fertility. Heavy metals can accumulate in the soil and can be harmful to wildlife.

In dry areas, fireworks can start wildfires, which can have a devastating impact on the environment and wildlife.

Chemicals Used in Fireworks

When it comes to fireworks, the bright and colorful displays that light up the sky are created by a variety of chemicals. These chemicals can have a negative impact on the environment, wildlife, and even human health. 

Heavy Metals

Mineral elements are commonly used in fireworks to create vibrant colors. For example, strontium is used to create red, barium for green, and copper for blue (3). However, when these metals are released into the air, they can have harmful effects on the environment. Heavy metals can contaminate water sources, soil, and even crops. They can also cause harm to wildlife, as they can accumulate in the food chain.

It’s important to note that not all fireworks contain heavy metals and perchlorates, or at least not to an equal extent. Some companies are now using alternative chemicals that are less harmful to the environment. However, it’s still important to be aware of the potential impact of fireworks on the environment and take steps to minimize that impact.

Types of Fireworks

When it comes to fireworks, there are various types that you can choose from. Each type has its own set of characteristics and environmental impact. Here are some of the most common types of fireworks:

Consumer Fireworks vs. Professional Fireworks

Consumer fireworks are the most common type of fireworks used by the general public. They are available in many different sizes and shapes, from small sparklers to large aerial fireworks. Consumer fireworks are typically made with paper and cardboard, and they contain various chemicals that create the colors and effects when ignited. These types of fireworks are often used for celebrations such as the Fourth of July or New Year’s Eve.

Professional fireworks are typically used for large-scale events such as concerts, sporting events, and public celebrations. These fireworks are much larger and more powerful than consumer fireworks, and they are designed to create large, impressive displays. Professional fireworks are typically set off by trained pyrotechnicians who have the knowledge and experience to handle them safely.

Sparklers

Sparklers are a type of consumer firework that are popular with children. They are small handheld fireworks that emit sparks when lit. While sparklers may seem harmless, they can actually be quite dangerous. They burn at extremely high temperatures, and they can cause serious burns if not handled properly.

The chemicals used to cause sparklers to burn, change colors, and spark the way they do can be harmful, as well as the waste created by packaging and after they’re burned.

On-Ground Fireworks

On-ground fireworks are a type of consumer firework that are set off on the ground. They typically emit sparks and flames, and they can be quite loud. On-ground fireworks can be dangerous if not handled properly, and they can also create a lot of smoke and air pollution in addition to the physical waste after they’re set off.

Aerial Fireworks

Aerial fireworks are a type of firework that are launched into the air. They typically create large explosions and colorful displays. Aerial fireworks are typically used in professional displays, but they can also be purchased by consumers in some states. These types of fireworks can be dangerous if not handled properly, and they can also create a lot of noise, air, water, and land pollution.

Alternatives to Fireworks

If you’re looking for alternatives to traditional fireworks, there are plenty of options available that are eco-friendly and won’t harm the environment. Here are some alternatives to consider:

1. Laser Light Shows

Laser light shows are similar to fireworks displays, but they don’t release pollutants into the air. They use lasers to produce colorful designs and patterns, making them a great alternative to traditional fireworks.

2. Projection Mapping

Projection mapping is a technique that uses projectors to create stunning visual effects on buildings, landscapes, and other surfaces. It’s a great way to add some excitement to an event without the use of fireworks.

3. Glow-in-the-Dark Parties

Glow-in-the-dark parties are a fun and unique way to celebrate without fireworks. Guests can wear neon clothing and accessories, and the party can be lit with black lights to create a colorful, glowing atmosphere.

4. Bonfires

Bonfires are a great way to celebrate and bring people together without the use of fireworks. They provide warmth and light and can be a fun way to roast marshmallows and enjoy some s’mores.

6. Drone Shows

Drone shows are becoming increasingly popular as an alternative to fireworks. They use drones to create intricate patterns and designs in the sky, providing a unique and exciting experience for viewers.

Overall, there are plenty of alternatives to fireworks that are eco-friendly and won’t harm the environment. Whether you choose laser light shows, projection mapping, or a good old-fashioned bonfire, there are plenty of ways to celebrate without fireworks.
