Toxic smog returns to Delhi after Diwali
Air pollution in the Indian capital has risen to hazardous levels after firecrackers were set off to celebrate Diwali despite a court ban. Residents awoke on Thursday to find the city blanketed in a toxic fog. The Supreme Court had restricted the timeframe for setting off firecrackers to only two hours in the night, but the order was openly flouted.
The levels of tiny particulate matter (known as PM 2.5) that enter deep into the lungs reached as high as 999 micrograms per cubic metre in some areas of the capital on Thursday morning, according to reports.
