The air quality in India's national capital took a severe hit on Friday, slipping into the 'very poor' category. The overall Air Quality Index (AQI) was recorded at 311, according to live data from the Central Pollution Control Board's (CPCB) SAMEER application.
Weather Conditions Trap Pollutants
The decline coincided with chilly winter conditions enveloping Delhi. Meteorological factors played a significant role, as pollutants were unable to disperse effectively. Unfavourable weather, including low wind speeds, caused harmful particles to linger close to the ground, creating a thick haze over the city.
Monitoring stations across various neighbourhoods reported air quality levels ranging from 'poor' to 'very poor'. This widespread deterioration has raised alarms among health experts and residents alike, concerned about the risks of prolonged exposure to such polluted air.
Cold Wave Threat to Further Worsen Air
The situation may not improve soon. The India Meteorological Department (IMD) has issued a forecast that spells more trouble. The weather agency predicts cold wave conditions at isolated places in Delhi between January 2 and 5.
This impending cold wave, coupled with consistently low wind speeds and falling temperatures, is expected to act as a lid over the city. These conditions will likely restrict the vertical and horizontal dispersal of pollutants in the coming days, potentially leading to a further accumulation of toxic air.
Public Health Concerns Mount
The combination of 'very poor' air and cold wave conditions presents a dual challenge for public health. Authorities often advise vulnerable groups, including the elderly, children, and those with respiratory conditions, to limit outdoor exposure during such periods. The persistent poor air quality underscores the ongoing struggle Delhi faces every winter, where weather and pollution sources combine to create a hazardous environment.
