A thick haze has fallen across New Delhi, the capital of India, closing schools.
This week authorities in Delhi announced that schools are to close for a week.
Delhi’s chief minister, Arvind Kejriwal, made the announcement saying that ‘schools are being shut so that children don’t have to breathe polluted air.’
Kejriwal said no construction activity would be allowed for four days to cut down dust from vast open sites.
On Saturday, levels of PM 2.5 particles – the smallest and most harmful, which can enter the bloodstream – topped 300 on the air quality index. That is 20 times the maximum daily limit recommended by the World Health Organization.
