Every year, Diwali celebrations in Delhi lead to a spike in air pollution, often reaching dangerous levels. Fireworks are a major contributor, releasing a surge of pollutants into the air. But why do fireworks cause such severe pollution, and what does this mean for residents' health? In this page, we explore the reasons behind the pollution spike during Diwali, the health risks of high AQI levels, and what long-term solutions can help improve air quality in Delhi and similar cities.

How do fireworks increase pollution during Diwali?
Fireworks release a variety of pollutants, including particulate matter, heavy metals, and chemicals that contribute to smog and haze. During Diwali, the widespread use of firecrackers causes a sudden spike in these pollutants, overwhelming the city's air quality management systems and leading to AQI levels above 350, which is considered 'severe'.
-
What are the health risks of AQI above 350?
An AQI above 350 indicates very unhealthy air, which can cause serious health problems. Short-term exposure can lead to respiratory issues, eye irritation, and aggravate existing conditions like asthma. Long-term exposure increases the risk of cardiovascular diseases and can even be fatal, especially for vulnerable groups like children, the elderly, and those with pre-existing health conditions.
-
Are there effective ways to reduce pollution during festivals?
Yes, some measures can help reduce pollution, such as banning or restricting firecracker use, promoting eco-friendly fireworks, and increasing public awareness. However, enforcement remains a challenge. Alternative celebrations like laser shows or community light displays can also be effective in reducing pollution while maintaining festive spirit.

What long-term measures can improve air quality in Delhi?
Long-term solutions include stricter regulation of industrial emissions, promoting cleaner transportation options, and reducing crop burning in surrounding regions. Investing in green infrastructure, expanding public transportation, and implementing policies to curb vehicle emissions are crucial steps. Additionally, public awareness campaigns and community engagement are vital for sustainable change.

Why do pollution levels spike during winter in Delhi?
Delhi experiences seasonal weather conditions in winter that trap pollutants close to the ground, creating smog and haze. Calm winds, low temperatures, and temperature inversions prevent pollutants from dispersing, causing pollution levels to rise sharply. Fireworks and crop burning further exacerbate this problem during the festive season.

Can 'green' firecrackers really help reduce pollution?
While 'green' firecrackers are marketed as environmentally friendly, experts warn they may still contribute to pollution, especially when used in large quantities. Their actual impact on air quality is still under study, and enforcement of regulations remains inconsistent. Reducing firecracker use altogether is considered the most effective way to protect air quality.
