after Diwali
\n new delhi
\nAir quality in India\u2019s capital New Delhi deteriorated to hazardous levels on Tuesday with readings the highest in the world, according to Swiss group IQAir, partly due to the use of firecrackers during Diwali, the Hindu festival of lights.
\nThe Supreme Court of India last week relaxed a ban on firecrackers in the city, permitting the use of so-called \u201cgreen crackers\u201d for a maximum three hours each on Sunday and Monday, although Reuters witnesses saw crackers being set-off outside the allotted times. Emissions from the crackers are 30% to 50% lower than conventional fireworks.
\nIQAir\u2019s reading for New Delhi was 442, making the Indian capital the world\u2019s most polluted major city. Its PM 2.5 concentration was more than 59 times the World Health Organisation\u2019s recommended annual guideline. PM 2.5 refers to particulate matter measuring 2.5 microns or less in diameter that can be carried into the lungs, risking deadly diseases and cardiac problems. India\u2019s Central Pollution Control Board (CPCB) also rated the city\u2019s air quality \u201cvery poor\u201d with an air quality index (AQI) measurement of 350. CPCB considers an AQI of 0-50 as good.<\/p>\n","protected":false},"excerpt":{"rendered":"
