Delhi Shrouded in Toxic Haze Following Diwali Celebrations

Delhi is currently engulfed in severe air pollution following the recent Diwali celebrations. The city is facing hazardous air quality levels that are exceeding recommendations set by the World Health Organization (WHO).

Air Quality Levels in Delhi

Delhi’s Air Quality Index (AQI) has recorded alarming figures. These can be broken down as follows:

• AQI of 101-200: Moderate
• AQI of 201-300: Poor
• AQI of 301-400: Very Poor
• AQI above 400: Severe

In certain areas, the AQI has reached levels 24 times higher than the WHO’s recommended limit of 15 micrograms of PM 2.5 per cubic meter.

Causes of Pollution

Several factors contribute to Delhi’s worsening air quality during the winter months. These include:

• Crop stubble burning in neighboring states.
• Low wind speeds trapping pollutants in the atmosphere.
• Emissions from vehicles.
• Use of fireworks during festivals.

Despite a ban on firecrackers in Delhi since 2020, instances of their use were reported widely during Diwali. The Supreme Court of India recently relaxed this ban, permitting the use of so-called “green crackers,” which claim to produce 20-30% less pollution compared to regular firecrackers. However, critics remain skeptical about their safety, as they still emit harmful pollutants.

Impact of Fireworks on Air Quality

Reports from local media indicate that traditional firecrackers were available in many shops, and their sound could be heard long into the night, even past the designated times set by the court. As a result, air quality in Delhi has been categorized as “very poor,” consistently exceeding AQI levels of 300.

This past weekend, officials implemented the Graded Response Action Plan (GRAP) to improve air quality. Restrictions were placed on diesel generators and the burning of coal and firewood in certain areas.

Public Sentiment and Future Outlook

Residents of Delhi have expressed their frustration with the ongoing pollution crisis. Many are hesitant to step outside due to the thick smog enveloping the city. Paras Tyagi, a local resident, noted that the situation is dire in both urban and rural areas.

Experts warn that easing restrictions on firecracker use could undermine public awareness of the dangers posed by air pollution, which has been emphasized in recent years. As the smog settles in, the residents of Delhi face a challenging winter ahead.
