Delhi's air quality plunges to hazardous levels as AQI breaches 300

Delhi's air quality deteriorated sharply on Monday as the Air Quality Index reached over 300, marking the season's most severe pollution episode to date. A thick blanket of haze settled over the national capital, with visibility significantly reduced across the city and surrounding areas.

The very poor air quality category poses serious health risks, particularly for vulnerable populations including children, the elderly, and individuals with pre-existing respiratory conditions. Health officials have advised residents to limit outdoor activities and use air purifiers indoors where possible.

Meteorological conditions are expected to sustain the dense smog over the coming days, according to weather forecasts. Stagnant atmospheric conditions and reduced wind speeds have trapped pollutants near the ground level, preventing natural dispersion of suspended particles.

The deterioration coincides with seasonal factors that typically worsen air quality in Delhi during late autumn and winter months. Agricultural burning in neighboring states, vehicular emissions, and industrial pollution combine to create hazardous air conditions during this period each year.

Authorities have urged residents and commuters to monitor air quality updates regularly and take necessary precautions to minimize exposure to polluted air.
