Three studies found that fireworks release pollutants into air and water. Researchers monitored particulate matter during a large event in the UK and detected sharp increases in airborne particles. Fireworks also release chemicals called amines, which contribute to haze and reduced air quality.

Fireworks may seem like a fun way to celebrate festivals, but new research reveals that they leave behind hidden pollution. Three recent studies published in American Chemical Society (ACS) journals examined the effects of fireworks on air quality, water chemistry, and potentially human health and the environment.

One study found that firecracker debris can alter water chemistry. When spent firecrackers are placed in lake and river water, they release significant amounts of metal ions and dissolved organic matter. This can interfere with microbial communities and aquatic ecosystems. Properly collecting and disposing of spent fireworks could help reduce these environmental effects.

Another study monitored particulate matter during a large, multi-day athletic event in the UK. Researchers detected sharp increases in both coarse and fine airborne particles throughout the event. The team linked much of the pollution to cooking emissions from food vendors and dust stirred up by vehicles. During the opening and closing ceremonies, they observed two distinct spikes in fine particulate matter.

A third study focused on chemicals called amines, which are included in some firework formulations. These compounds can react in the atmosphere to form aerosols that contribute to haze and reduced air quality. Researchers measured amines in both gases and airborne particles during Lunar New Year celebrations in a suburban area of China. The findings revealed substantial increases in several amines compared with a non-celebratory period.

The researchers say the results suggest that fireworks contribute more than visible smoke to the haze that often lingers after major celebrations, adding another layer to their environmental impact.

Why It Matters

Fireworks pollution can affect air quality and human health in India, especially during festivals like Diwali. It's essential for students to understand the hidden costs of fireworks and how they can contribute to reducing pollution.
