Thousands of schools closed as smog envelopes India, Pakistan

NEW DELHI: Schools closed across large swathes of north India yesterday as a hazardous fog of toxic pollution cloaked the region for a third day, with growing calls for urgent government action to tackle what doctors are calling a public health emergency, reports AFP.
Punjabs government said it was closing all 25,000 schools in the state for the rest of the week due to the acrid air blanketing north India and parts of neighbouring Pakistan. The decision came a day after Delhi authorities ordered all 6,000 schools in the capital to shut until Sunday.
Low winds and the annual post-harvest burning of crop stubble in Punjab and neighbouring areas have caused the levels of dangerous pollutants in the air to spike to many times the levels considered safe.
Air quality typically worsens before the onset of winter as cooler air traps pollutants near the ground and prevents them from dispersing into the atmosphere, a phenomenon known as inversion.
Figures on the US embassy website showed levels of PM2.5 -- the smallest particulates that cause most damage to healthspiked at over 1,000 on Wednesday afternoon in Delhi, though by Thursday they had fallen to 590.
The World Health Organizations guidelines say 25 is the maximum level of PM2.5 anyone can safely be exposed to over a 24-hour period. Doctors say the microscopic particles can penetrate deep into the lungs, increasing the risk of heart attacks and strokes.
Delhi once again has become a veritable gas chamber with denizens finding it difficult to breathe, The Times of India said Thursday, joining growing calls for government action to curb the chronic pollution, which the Indian Medical Association this week termed a public health emergency. Air pollution during winter months has become a catastrophe for large parts of north India, the countrys most read English-language newspaper said in an editorial blaming political apathy.
Its high time the question is asked: why cant authorities enjoying jurisdiction over the national capital of an aspiring great power... come up with concrete measures to tackle the worlds worst air pollution.
As pressure mounted on the government, authorities in Delhi ordered a ban on all construction work and barred lorries from entering the city.
Around 50,000 mostly diesel-fuelled lorries pass through Indias capital every night and they are a major contributor to the pollution plaguing the city.
Struggling to respond -It is the second year running that Delhinow the worlds most polluted capital with air quality worse than Beijinghas faced such high levels of PM2.5.
Media reports said the thick smog had also led to a series of road accidents in north India. Eight students were killed late Wednesday when a truck ploughed into them as they waited for a bus on a roadside in Punjab.
Since 2014, when WHO figures showed the extent of the crisis, authorities in Delhi have closed power plants temporarily and experimented with taking some cars off the road. But the temporary measures have had little effect.
Under pressure to respond, Delhis Chief Minister Arvind Kejriwal on Thursday sought to blame stubble burning by farmers in neighbouring states. We we will continue facing this every year until the neighbouring state governments resolve the issue of crop burning, he told reporters in Delhi.
The practice of burning crop stubble remains commonplace in north India despite an official ban. Kejriwal said his government would decide in the next day or two whether to reintroduce restrictions on driving cars in the city.
BBC report adds: The government in the Indian capital, Delhi, has reintroduced car rationing to curb alarming levels of pollution.
Private cars with even and odd number plates will only be allowed on alternate days from 13 to 17 November. Car rationing was trialled last year, but its not clear whether it helped to bring down pollution.
Pollution levels are 30 times the World Health Organizations recommended limit in some areas. Delhis chief minister has called the city a gas chamber.
Arvind Kejriwal said the government had already taken a number of steps like temporarily banning construction work and raising parking fees to discourage people from driving their cars.
He added that car rationing, popularly known as the odd-even scheme, was also aimed at reducing pollution. But experts say the plan had little impact on pollution last year, although it definitely reduced chronic congestion.
More than a third of the citys three million private cars were off the road during the trial period last year. Delhi sees pollution levels soar in winter due to farmers in neighbouring Punjab and Haryana states burning crop stubble to clear their fields.
Low wind speeds, dust from construction sites, rubbish burning in the capital and firecrackers used in festivals also contribute to increasing pollution levels.
