KARACHI (Reuters) - Pakistan's Punjab declared a health emergency due to toxic smog on Friday, banning construction, shutting schools for another week and moving universities online, with a three-day lockdown possible, the province's senior minister said on Friday.
Punjab battles toxic smog every winter as cold air traps dust, emissions, and smoke from illegal stubble burning on fields. Air quality has deteriorated drastically in recent weeks and the province's capital Lahore currently ranks as the world's most polluted city, says IQAir.
"A complete lockdown will be enforced on Friday, Saturday, and Sunday (next week) if the situation does not improve by Wednesday," said Punjab Senior Minister Marriyum Aurangzeb, addressing a press conference in Lahore.
Citizens were advised to stay indoors. Air Quality Index (AQI) readings in Lahore reached 637 at 3 p.m. (1000 GMT), according to Swiss group IQAir, significantly higher than levels recommended by the World Health Organization.
The government had ordered the closure of construction, brick kilns, and furnace-based plants in Lahore and the city of Multan, the minister said.
Punjab's government had last week ordered schools to close until Nov. 17, and on Friday the shift to online learning was extended for another week. Colleges and universities will also shut down, moving to virtual classes.
The eastern province has already banned entry to parks, zoos, playgrounds and other public spaces.
South Asia faces severe pollution each year due to trapped dust, emissions and stubble burning - the practice of setting fire to fields after the grain harvest.
Punjab has blamed this year's particularly high pollution levels partly on toxic air flowing from neighbouring India, where air quality has also reached hazardous levels.
India's capital of New Delhi, the world's most polluted capital city, banned all non-essential construction, moved younger children to virtual classrooms and asked residents to avoid using coal and wood from Friday to combat increasing air pollution.
New Delhi's air quality level reached 539 on Friday, according to live rankings by IQAir, the worst amongst global capitals.
