Delhi Air Quality Worsens Again: The air quality in Delhi has once again taken a serious turn for the worse, raising fresh concerns for residents across the national capital. According to official data released by the Central Pollution Control Board, the Air Quality Index recorded a value of 353 at 8 AM on Saturday, placing it firmly in the very poor category. This is not an isolated incident, as the city has now experienced very poor air quality for the second consecutive day. On Friday morning, the AQI was already alarming at 305, indicating a sustained pollution episode rather than a short-term fluctuation.

Recent Trends in Delhi’s Air Quality

Over the past week, Delhi had witnessed a noticeable improvement in air conditions. This positive change was largely attributed to the strict implementation of Graded Response Action Plan Stage 4 measures, which were enforced to curb pollution sources aggressively. These measures included restrictions on construction activities, limitations on vehicle movement, and tighter controls on industrial emissions. As a result, by midweek, the AQI had dropped to 221, which falls under the poor category but was still a relief compared to earlier hazardous levels.

However, this improvement proved to be temporary. On Wednesday, authorities decided to lift the restrictions as pollution levels showed signs of easing. Soon after, air quality began to deteriorate again, highlighting how fragile the situation remains and how quickly conditions can worsen once preventive measures are relaxed.

Factors Contributing to the Decline

Several factors are believed to be responsible for the sudden decline in air quality. Weather conditions such as low wind speed and a drop in temperature reduce the dispersion of pollutants, causing them to accumulate near the ground. Additionally, emissions from vehicles, industrial activity, and local sources like dust and waste burning continue to add to the pollution load. Seasonal factors also play a role, as winter months typically see higher pollution levels due to atmospheric conditions that trap particulate matter.

Area-Wise AQI Levels Across Delhi

A closer look at area-specific data reveals that pollution levels vary across different parts of the city, with many regions reporting extremely high AQI values. Some of the most polluted areas include Jahangirpuri with an AQI of 414, Anand Vihar at 410, and Rohini and Narela both recording 406. These figures fall into the severe to very poor range, posing significant health risks to residents.

Other densely populated or industrial zones also reported worrying numbers. Bawana recorded an AQI of 395, Wazirpur stood at 398, and DTU reported 399. Commercial and traffic-heavy areas such as Chandni Chowk, ITO, Patparganj, and Okhla Phase 2 all hovered around 378 to 379, reflecting consistently poor air conditions. Even residential localities like Dwarka Sector 8 and RK Puram reported AQI values of 368 and 367 respectively.

In comparison, IGI Airport showed a relatively lower AQI of 261, though this still falls within the poor category and is far from safe. North Campus of Delhi University recorded an AQI of 353, mirroring the citywide average.

Health Implications for Residents

Prolonged exposure to very poor air quality can lead to a range of health problems, especially for children, the elderly, and individuals with pre-existing respiratory or cardiovascular conditions. Symptoms may include irritation of the eyes and throat, breathing difficulties, headaches, and a higher risk of asthma attacks. Medical experts often advise limiting outdoor activities during such periods and using protective measures such as masks and air purifiers indoors.

The Way Forward

The recurring pattern of improvement followed by rapid deterioration suggests that long-term solutions are urgently needed. Temporary restrictions can offer short-term relief, but sustained efforts focusing on cleaner transport, better waste management, and stricter industrial regulations are essential for lasting improvement. Public awareness and individual responsibility also play a crucial role in reducing pollution at the source.

As Delhi continues to grapple with worsening air quality, consistent monitoring and timely policy interventions remain key to protecting public health and improving the city’s environmental outlook.
