Delhi most polluted city as AQI hits hazardous levels

What this story says

  • Delhi overtook Lahore to become the world's most polluted city on Friday.
  • Air quality in Delhi was rated 'hazardous' by IQAir at 334, and 'severe' by India's Central Pollution Control Board at 403.
  • The differing AQI readings are due to variations in scales and methodologies.
  • Pollution in the region is a seasonal issue exacerbated by winter air, emissions, dust, and agricultural burning.

Delhi surpassed Lahore, Pakistan, to become the world's most polluted city on Friday. Air quality in the Indian capital reached hazardous levels, with thick smog significantly reducing visibility. The city, home to 20 million people, experienced a dense grey haze that obscured streetlights and made distant objects difficult to see.

Differing air quality readings

IQAir recorded Delhi's Air Quality Index (AQI) at 334, classifying it as 'hazardous'. In contrast, India's Central Pollution Control Board reported a higher AQI of 403, rating the air quality as 'severe'. These discrepancies arise from the different scales and methodologies employed by the two organisations in measuring and classifying pollution levels.

What the coverage left out

None of the left-rated digests mention the specific concentration of PM2.5 particles reported by The CSR Journal. None of the centre-rated reports mention the PM2.5 concentration. The right-rated digest does not mention the PM2.5 concentration.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

  • Four left-rated reports focused on Delhi becoming the world's most polluted city. Three of these noted the 'hazardous' AQI reading of 334 from IQAir. Two reports mentioned the differing AQI figure of 403 from India's Central Pollution Control Board, classifying it as 'severe'. The seasonal nature of pollution in northern India and Pakistan was noted by two reports. The Independent mentioned the contrast between Delhi's AQI and the benchmark for good air quality.

Centre

  • Two centre-rated reports highlighted Delhi overtaking Lahore as the world's most polluted city due to hazardous air quality and reduced visibility from smog. Both mentioned the city's population of 20 million. The Jerusalem Post, which provided a full report, included details about cars and motorcycles emerging from smog and obscured streetlights, citing videos from news agency ANI. It also noted the seasonal aspect of the pollution problem in northern India and Pakistan.

Right

  • The single right-rated report focused on Delhi becoming the world's most polluted city as air quality dropped. It included a mention of cars and motorcycles emerging from dense smog, which also appeared to obscure streetlights on the city's main roads, according to videos from news agency ANI.
