Delhi Air Quality Turns ‘Severe’ Again Amid Rising Winter Pollution

Air quality in several parts of Delhi slipped into the ‘severe’ category on Monday, signalling another alarming spike in pollution as winter conditions tightened their grip on the city. According to monitoring agencies, areas including Anand Vihar, Ashok Vihar, Punjabi Bagh, and Vivek Vihar recorded AQI levels above 450, posing serious health risks to residents.

Meteorologists attribute the sudden deterioration to a combination of falling temperatures, stagnant wind movement, and increased local emissions. Low wind speed has trapped pollutants close to the surface, while dense fog and rising vehicular activity have further intensified particulate concentrations, particularly PM2.5.

Pollution control experts warn that prolonged exposure to severe air quality can trigger respiratory distress, throat irritation, fatigue, and worsen chronic conditions such as asthma and heart disease. Hospitals have reported a rise in cases of breathlessness and eye irritation, especially among children and the elderly.

Authorities have issued advisories urging people to limit outdoor activities, avoid morning walks, and use N95 masks when stepping out. Schools and offices have also been asked to consider hybrid schedules if pollution levels worsen.

The Delhi government is expected to review emergency measures under the GRAP (Graded Response Action Plan), which may include restrictions on construction activities, enhanced public transport deployment, and temporary vehicle curbs.

The current spike underscores the capital’s recurring winter pollution crisis, driven by a mix of urban emissions, regional factors, and unfavourable weather patterns. With no immediate relief expected, residents may face another prolonged period of hazardous air quality.
