As winter approaches, Delhi’s air quality deteriorates. Diwali pollution is getting worse by the day, especially in Delhi. Nobody is in the dark about the situation. Air contaminants are always present in air, however they are not necessarily apparent to the naked eye. In contrast, after the Diwali festival, there is a considerable increase in air pollution. This bad air quality endangers the health of children, the elderly, and other vulnerable groups. When you inhale this heavily polluted air, you may experience physical discomfort and irritation, which can have major health impacts.

Does Diwali cause pollution?

There are numerous sorts of firecrackers on the market. Depending on the chemical used to make them, crackers emit a variety of dangerous air pollutants. These contribute to a rise in the amount of dust and air pollutants in the environment. They produce specific compounds after combustion, including as Cu, S, Zn, and many more, which contaminate the environment and put inhabitants’ health at danger, particularly children. They are more vulnerable to the harmful Diwali pollution. The combustion process requires O2 to function.

Diwali pollution due to the fireworks

Reduced visibility due to smog formation

The combustion of firecrackers produces a variety of hazardous gases, including SO2, CO, CO2, and numerous metals and fuses. These release highly dangerous air pollutants and gases, which constrict our lungs by vaporizing poison and polluting the soil and water. This toxin is absorbed by many animals, birds, wildlife, plants that grow in that soil, and so on. As a result, the consequences of a few hours of fun will harm humans, animals, plants, and the entire environment for months. People do not use firecrackers in a responsible manner. The cracker remains cause litter on the roadways and blockage in the drains, leading them to overflow and cause a massive mess. This further goes on to pollute the waters, making them unfit to drink, wash, clean, etc.; this is something the whole country faces.

Effects of Diwali pollution

On the environment: 

Condition of roads after Diwali celebrations

Many pyrotechnics contain oxidizers, which supply the O2 required for combustion and explosion. These oxidizers are perchlorates, which dissolve easily in water and pollute rivers, lakes, and, ultimately, drinking water. They emit chemicals that pollute the air and remain in the atmosphere for days, resulting in fine dust and smoke clouds. As a result, the local air quality suffers. This reduces vision even more and is blamed for road accidents caused by poor visibility.

On the citizens of Delhi:

Extreme levels of air pollution following the Diwali festival have a variety of -ve impacts on your health.

As the air quality in Delhi worsens, residents strain to breathe. O2 is a vital and critical component of survival and good body function. Breathing without a mask in the post-Diwali smog is like directly breathing poison. It is strongly advised not to leave the house without using an anti-pollution mask, particularly in the weeks following Diwali. Citizens have reported the following health effects:

  1. Difficulty breathing as a result of the increased amount of smoke and dust particles produced by firecracker burning.
  2. Worsening of respiratory illnesses such as Asthma
  3. Irritation in the eyes, nose, and throat
  4. Headaches and dizziness due to smoke inhaling 
  5. Burning sensation in the eyes
  6. Skin itching and allergies such as eczema
  7. Temporary or permanent hear loss
  8. High blood pressure due to loud noise
  9. Sleep disturbances
  10. Respiratory illnesses such as chronic bronchitis and pneumonia

Air quality trends post Diwali


  • Authorities issued a red warning and barred construction operations overnight.
  • Fireworks were restricted, and only green crackers emitting 30% less pollution were approved.
  • Kejriwal’s govt. announced the launch of efforts to reduce air pollution, such as the odd-even program.
  • To address post-Diwali pollution in eastern Delhi, EMDC sprayed water on roads in Laxmi Nagar and neighboring areas.


  • Despite a blanket ban on firecrackers in the Delhi NCR region, the capital’s already dirty air worsened dramatically following Diwali, while air quality improved.
  • People disregarded the NGT’s restriction on firework burning, that further caused Delhi’s AQI to fall into the ‘severe’ category.
  • Crop residue burn and reduced wind speeds have also led to poor air quality.
  • On October 14, official govt. data indicated that the city’s air quality was ‘poor.’
  • Certain contaminants were found in ‘very poor’ or ‘severe’ levels in some Delhi districts.
  • The most afflicted location in Delhi was Rohini, where the AQI reached 999g early in the morning following Diwali celebrations.


  • The winter air in Delhi averaged 220g of PM2.5, but during the peak of Diwali fireworks on November 11, the readings skyrocketed to more than 700g.

What is the govt. doing for Diwali pollution in Delhi?

The Delhi govt. has launched several measures, including the odd-even rule, a cracker ban, and others, to reduce air pollution, particularly during the Diwali season. This year, the govt. of Delhi unveiled a 15-point action plan to tackle air pollution. Furthermore, Arvind Kejriwal stated that the strategy will serve as a roadmap for the govt. to use in combating air pollution this year.

“The Delhi government’s hard efforts have begun to bear fruit. PM10 levels were 18.6% lower in 2021-22 than in 2017-18. We have reduced pollution by providing 24 hour electricity, shutting down thermal plants, regularly inspecting construction sites, convincing industries to relocate to PNG, increasing green cover, enacting an electric vehicle policy, adding electric and CNG buses to our public transportation fleet, and developing smog towers. As a result, I am optimistic that we will defeat pollution with the aid of the people of Delhi “According to Kejriwal.
