Fireworks - Cheap Thrills with Toxic Consequences

Fireworks contribute to polluting or damaging our planet in various ways throughout their life cycle.

• Manufacturing: Raw materials and energy are used to create the final firework product. Firework ingredients often come from elements that need to be mined from the earth. Mining is not exactly environmentally friendly. Minerals then need to be processed and isolated... often with chemicals. Fireworks use plastic plus paper & cardboard (which kills trees) and are all made at factories that pollute.
  
  
• Transportation: Firework components are transported to the firework assembly plant, finished fireworks are transported to their various distribution centers and stores. Transporting may include planes, boats, and trucks. I don't need to tell you the pollution that vehicles cause. And don't forget that the consumer drives to purchase the fireworks, sometimes hundreds of miles to another state to bypass local restrictions.
  
  
• Combustion:
  
  
  • Air Pollution: The smoke from fireworks consists mainly of fine toxic dusts (particulate matter) that can easily enter the lungs. This represents a real threat for people with asthma or multiple chemical sensitivity (MCS). Smoke from fireworks combustion may contain a mixture of sulfur-coal compounds, traces of heavy metals, and other toxic chemicals or gases. The combustion cloud can contain harmful fumes such as ozone, sulfur dioxide and nitric oxide. Smoke from consumer fireworks is of most concern because they are released at a low level which makes inhalation more likely compared to professional displays. Additionally, in this time where the issues of climate change and global warming are being presented with a sense of urgency, we need to be concerned about the greenhouse gases fireworks produce, which include Carbon dioxide (CO2) and ozone.
    
    
  • Water Pollution: Fireworks fallout can contaminate water supplies and residue on the ground can be carried away by rain and end up in our lakes, rivers, or oceans.
    
    
  • Noise Pollution: Fireworks can be loud and the vibrations can travel far. In the middle of the night fireworks often disturb people trying to sleep. Fireworks can exceed 140 decibels and noise at 85 decibels or above can damage hearing. Some people also argue the noise from fireworks scares pets.
  
  
  
• Accidents: In 2000-2004, fireworks started an estimated 32,300 reported fires per year, including 2,700 building and vehicle fires. More fires are reported on the 4th of July than any other day of the year [1].

For the color effect of fireworks, toxic heavy metals like barium, aluminum, lead, mercury salts, antimony, copper, and strontium can be used in firework compositions. Outdated heavy metals that have been used in the past include rubidium and cadmium. Some toxic elements are supposedly not used in fireworks anymore like lead compounds, chlorates, and mercury as mercurous chloride (calomel), but some firework chemical outlets still sell some of these ingredients, they can still be seen in some pyrotechnic chemical lists, and homemade fireworks makers still sometimes talk about using them.

Many fireworks are imported from China which is scary because they have a proven track record of cutting corners by using cheaper, more toxic materials. Some of the metals also have radioactive isotopes... hopefully they aren't being used in any fireworks. The American Fireworks Standards Laboratory (AFSL) has established a testing and certification program for Chinese and U.S. fireworks to determine if they are being produced according to AFSL Standards (which meet all U.S. federal requirements). There is a list of prohibited toxic chemicals in the standards but unfortunately participation in the program is voluntary for manufacturers and importers. Firework shipments that pass standards only assure that one random sample from the lot has been tested and met all requirements [2]. Will you trust the quality of your air to China??

A case study has shown that within 1 hour of fireworks displays levels of Strontium in the air increased 120 times, Magnesium 22 times, Barium 12 times, Potassium 11 times, and Copper 6 times more than the amount present in the air before the event. Strontium was found to be the best tracer in this study because it measured very high during the event and much lower at other time intervals which indicated that it was mostly a result of the fireworks display. [4]

Another study found that firework events brought air pollution spikes in suspended particles, Nitric oxide (NO), Sulfur dioxide (SO2), and created and dispersed an aerosol cloud hosting a range of metallic elements. The researchers found that although the "recreational pollution" from fireworks is transient in nature, the pollutants are highly concentrated and add significantly to the total yearly metal emissions and the particles are on average small enough to be easily inhaled which poses a health risk to sensitive individuals. [5]

Researchers have found that fireworks can create a burst of ozone which is an extremely reactive greenhouse gas molecule that can attack and irritate the lungs. The ozone is believed to be caused by ultraviolet light released by chemicals in fireworks... which in this study were sparklers. [7]

• How about we protect our health and the health of our outdoor environment by switching to an environmentally friendly laser light show?
• How about a block party to celebrate?
• A stunt kite show at night with some LED's would be cool.
• Try watching the stars or organize an outdoor movie.
• Electronic fireworks display lamps produce colorful explosions of light all night long without the pollution or noise of real fireworks.
• Electronic pyrotechnics don't use explosives either. Electronic blasts can form a canopy up to 25 feet in the air that rain down glitter, confetti, rose petals or even candy.
• Just imagine all the possible more meaningful and beneficial ways we could use all the money spent on fireworks that wouldn't pollute our environment.
  
• If fireworks must go on then displays should use air-launch technology, which utilizes compressed air to launch the fireworks instead of gunpowder, in combination with fireworks with low-gunpowder formulations. There is talk of new shells that use "biodegradable plastic" but what remains to be seen is if they are 100% non-toxic and leave no nano-plastic residues after breakdown, plus we still need to know what conditions they require to biodegrade.
• Low-smoke pyrotechnics produce practically none of the smoke or ash that traditional black powder fireworks do. Although they are being tagged as environmentally friendly or "green fireworks" the combustion byproducts still contain carbon dioxide which is a harmful greenhouse gas and also trace amounts of toxic metal salts. In addition ammonium perchlorate could still be used as an oxidant which still has the potential to contaminate water supplies. In a positive note less heavy metal salts are needed to produce the color effects. Unfortunately fireworks will never be eco-friendly but will be subject to greenwashing that distracts people with good intentions from the overall negative environmental impacts.

We also need to be more environmentally responsible as well. When you buy fireworks you are buying the whole pollution cycle... from the beginning to the end of the product. We should be concerned about how all the pollutants related to fireworks can affect our environment and our health. Fireworks not only pollute the air and water with heavy metals, etc. but they also cause noise pollution and physical litter. Does anyone enjoy picking up stray fireworks (bottle rockets, etc.) from their yard, garden, etc? When I hear about fireworks safety it makes me laugh because the pollution from these colorful displays of toxic exploding materials doesn't seem safe to me. It really seems to me that the cheap thrills that fireworks provide are just an empty distraction and really have nothing to do with the actual true recognition of a particular holiday.

• Write, call, or meet your local or state officials and tell them your concerns regarding outdoor air pollution and noise pollution from fireworks.
• The Clean Air Act permits state and local governments to enact laws relating to the prevention and control of outdoor air pollution.
• Pollutants discharged by fireworks also need to be regulated in accordance with the Clean Water Act. Recently some environmental groups have caused the cancellation of some fireworks shows held over water, after threatening organizers with a Clean Water Act lawsuit for lacking the appropriate permits.
• Boycott outdoor fireworks displays and encourage others to do the same.
• Educate others by sharing the pollution dangers of fireworks.
