Lahore and Delhi grapple with severe air pollution crisis

Lahore and Delhi are experiencing acute air pollution episodes that have pushed air quality indices into hazardous territory, prompting health warnings across the region. On November 3, Lahore's air quality index reached 447—well into the "hazardous" range where health impacts affect the general population. Such elevated pollution levels typically warrant advisories for vulnerable groups including children, the elderly, and those with respiratory conditions.

The spike in air quality degradation comes as South Asia enters its winter season, when meteorological conditions typically trap pollutants close to the ground. Temperature inversions, reduced wind speeds, and increased heating demands converge to worsen air quality across the region's major population centres.

Cities across Pakistan and India have seen recurring episodes of severe air pollution during autumn and winter months. The problem stems from multiple sources including vehicle emissions, industrial discharge, crop burning in agricultural areas, and construction dust. Transboundary pollution has also been cited as a contributing factor in cities near shared borders.

Meteorological departments are monitoring conditions closely, with forecasts suggesting potential improvement once wind patterns shift. Health authorities have advised residents to limit outdoor activities, use air purifiers indoors, and consider wearing protective masks during peak pollution hours. Schools and public institutions may implement contingency measures if pollution levels persist at hazardous thresholds.
