Delhi Air Pollution Surges Over 30 Times WHO Limit Amid Diwali Preparations

NEW DELHI: Toxic air pollution in India’s capital surged to more than 30 times the World Health Organisation’s recommended daily limit on Wednesday, as data from air monitors revealed alarming levels of PM2.5 particles.

The spike in pollution levels comes just three days after authorities implemented stricter measures, including traffic and construction restrictions, aimed at combating the persistent smog that envelops one of the world’s most polluted cities, home to over 30 million residents. Monitoring firm IQAir reported PM2.5 levels exceeding 461 micrograms per cubic metre in certain areas.

This deterioration in air quality poses significant health risks for citizens, particularly as the city approaches Diwali, the Hindu festival of lights, when firework displays are expected to exacerbate the already hazardous conditions. Although the Supreme Court has permitted the limited use of “green” firecrackers designed to minimize emissions, enforcement of these restrictions remains a challenge, with many residents disregarding the rules.

Looking ahead, authorities are likely to intensify efforts to monitor air quality and enforce regulations as Diwali approaches. The environment ministry attributes 23% of Delhi’s winter pollution to vehicle emissions and 20% to biomass burning, including farm stubble fires, highlighting the urgent need for comprehensive strategies to address the city’s chronic air quality issues.
