Delhi Air Quality Deteriorates Post-Diwali Amid Political Disputes

Delhi experienced a sharp decline in air quality on the morning following Diwali, with the Air Quality Index (AQI) reaching 372 at 10:00 AM. Despite a slight improvement to 333 by 7:00 PM, the air remained in the 'very poor' category, signaling hazardous pollution levels across the city. The sudden rise in pollution has sparked heated political debates, with both the ruling Bharatiya Janata Party (BJP) and the opposition Aam Aadmi Party (AAP) accusing each other over the surge in stubble-burning incidents in Punjab on Diwali day.

The reliability of pollution data came under scrutiny as several official monitoring stations reportedly went offline during the peak hours of firecracker use on Sunday night. Independent agencies reported even more alarming pollution levels, suggesting the government’s figures may underestimate the true extent of air pollution in Delhi and the National Capital Region (NCR).

Expert Opinions on Pollution Spike

Environmental specialists pointed to the extensive use of firecrackers during Diwali, which continued well past the midnight deadline set by the Supreme Court. This violation contributed significantly to the pollution surge. Anumita Roychowdhury, executive director of research and advocacy at the Centre for Science and Environment (CSE), emphasized the need for sustained action rather than seasonal measures. She stated, "The recurring pollution problem in Delhi-NCR stems from a lack of year-round strategies. Upgrading infrastructure and implementing permanent solutions is crucial. Firecrackers, though their total effect is hard to quantify, cause intense short-term pollution that worsens the already degraded air quality."

Pollution levels were not limited to Delhi alone; neighboring states like Haryana, Punjab, and western Uttar Pradesh recorded AQI readings above 350, classified as 'very poor.'

Health Impact and Medical Response

Medical facilities in the area have witnessed a rise in respiratory complaints. Hospitals reported about a 30 percent increase in patients with breathing difficulties since the AQI crossed the 'severe' threshold. The surge in respiratory ailments affects people across all age groups, including children, young adults, and seniors.

Nitesh Kumar Das, organizing secretary of the Gig Workers Association, highlighted the risks faced by delivery personnel who worked extensively during Diwali despite hazardous air conditions. Many gig workers took multiple orders per trip and worked longer hours to benefit from price surges, which Das noted could soon reflect in worsened respiratory health.

Dr. Vikas Mittal, director of pulmonology at CK Birla Hospital, noted increased outpatient visits related to symptoms such as persistent cough, breathlessness, wheezing, and throat irritation. Dr. Ravi Shanker Jha of Fortis Faridabad also observed a 10 percent rise in hospital admissions for respiratory issues. He warned that some patients delay hospital admission during festive seasons, which can aggravate their conditions.

Experts pointed out that chronic exposure to polluted air contributes to long-term health problems such as chronic bronchitis, asthma, and chronic obstructive pulmonary disease (COPD). Those with pre-existing conditions and the elderly are especially vulnerable to complications.

Political Disputes Over Pollution Causes

The pollution surge has also triggered a political blame game. Delhi minister Kapil Mishra accused Punjab's AAP government of a suspicious and sudden rise in stubble-burning incidents on Diwali, suggesting some fields were deliberately set on fire during celebrations. Mishra called for an investigation, urging Punjab Chief Minister Bhagwant Mann to initiate inquiries and file FIRs where necessary. He also recommended examining phone records of local officials to uncover possible foul play.

Data from the Indian Agricultural Research Institute (IARI) indicated a 607 percent increase in stubble-burning incidents in Punjab between November 7 and 8. However, Haryana, governed by the BJP, recorded an even higher proportional rise, though from a smaller base.

In response, former Delhi minister Saurabh Bharadwaj dismissed Mishra’s claims, arguing that smoke from Punjab cannot reach Delhi within minutes due to the time it takes for air pollutants to travel. Bharadwaj also accused the Delhi government of manipulating pollution data by placing monitoring stations near greener areas and watering these sites to artificially lower readings.

The Larger Context

Delhi’s struggle with air pollution is a recurring issue, especially during the winter months when weather conditions trap pollutants close to the ground. The combination of agricultural stubble burning in neighboring states, vehicle emissions, industrial pollution, and festive firecracker use creates a hazardous environment. Experts and activists continue to call for integrated, year-round policies to address this public health challenge rather than temporary measures during high-pollution seasons.

As the city grapples with these persistent problems, the debate over data accuracy and political finger-pointing underscores the complexity of managing air quality in a densely populated urban center with diverse pollution sources. The need for transparent monitoring, effective enforcement of pollution controls, and public awareness remains critical to improving Delhi’s air quality in the long run.
