- All Delhi schools will remain closed till Sunday over toxic smog
- Can't compromise children's health, said Minister Manish Sisodia
- Pollution in Delhi spiked hitting 30 times the WHO's safe level
"Due to the deteriorating air quality in Delhi, the health of children cannot be compromised. We have ordered the closure of all the schools in Delhi until Sunday," tweeted Manish Sisodia.
Delhi woke up on Wednesday to a second day of haze as pollution spiked, hitting 30 times the World Health Organization's safe level, prompting doctors in the national capital to warn of a public health emergency.
A dense grey smog shrouded the roads of the world's most polluted capital and many pedestrians and bikers wore masks or covered their mouths with handkerchiefs and scarves.
"I would request people to avoid morning walks. The situation is close to a severe crisis," Mr Sisodia had said yesterday as he announced that junior schools would be closed on Wednesday. He had promised to review the situation, "on an hourly basis if necessary."
The Indian Medical Association has declared a public health emergency, urging administrators to "curb this menace", while a Supreme Court-appointed panel has recommended emergency measures like four times the parking fees to discourage the use of cars, and reduced metro fares.
Delhi's air quality typically worsens ahead of the onset of winter as cooler air traps pollutants near the ground, preventing them from dispersing into the atmosphere, a phenomenon known as inversion.
High levels of moisture in the air and a lack of wind mean emissions have been trapped in the environment, according to the Central Pollution Control Board.
Firecrackers set off to celebrate Diwali last month added to the toxic mix created by pollution from diesel engines, coal-fired power plants and industrial emissions. The problem has been further exacerbated by the burning of crop stubble by farmers after the harvest in neighbouring states, a practice that remains commonplace despite an official ban.
