Delhi air quality deteriorates to 'poor' as pollution grips northern India

Delhi's 24-hour average Air Quality Index (AQI) stood at 232 in the 'poor' category as of 9 a.m. on October 28, as per readings from the Central Pollution Control Board (CPCB). The index measures concentrations of pollutants and categorizes air quality on a scale where readings above 201 are classified as 'poor,' typically triggering health advisories for vulnerable populations.

The deterioration in air quality has extended beyond Delhi to affect several parts of northern India, with multiple monitoring stations reporting similar levels of pollution. An AQI in the 'poor' range poses risks particularly for children, elderly persons, and those with respiratory or cardiac conditions.

The CPCB continuously monitors air quality across the country through its network of automated monitoring stations. The data helps assess pollution levels and guide public health interventions during periods of elevated air pollution. Residents in affected areas are advised to check local air quality forecasts and take appropriate precautions.
