Smog more toxic than can be measured by monitoring devices has blanketed the Indian capital this week, months before the start of Delhi’s traditional “pollution season”.
A thick haze was visible across the city from Tuesday and some government pollution monitors have recorded concentrations of 999 – the highest they can measure – as dust storms kicked up in nearby Rajasthan state blanketed the region.
Though the billowing clouds of dust and sand were blamed for the immediate spike in pollution levels, the sight of dense smog engulfing Delhimonths before winter has underscored a growing awareness that harmful air is a year-round problem for the city.
Air quality in Delhi usually begins to plummet in October when slower winds and cooler temperatures trap pollutants closer to the ground.
But data published by the government’s Central PollutionControl Board shows that air quality has been classed “very unhealthy” – with index scores as high as 270 – every April and May for the past three years, or since authorities began collecting and publishing the statistics.(▪ ▪ ▪)
