LAHORE (AP) – Toxic grey smog has sickened tens of thousands of people in Pakistan’s cultural capital of Lahore, forcing authorities to shut schools, markets and parks for four days, officials said on Thursday.
The decision came after the country’s second-largest city, with a population of 11 million, was repeatedly ranked the world’s most polluted city.
Doctors advised people to wear face masks and stay at home. Residents said many people were coughing and having breathing problems. “Wearing of masks and staying at home are the two easiest solutions to avoid getting rushed to hospitals with respiratory-related diseases, infections in eyes and skin diseases,” said a doctor at Lahore’s main Mayo Hospital Salman Kazmi, where thousands of people were treated for such ailments this week.
On Thursday, the concentration of PM 2.5, or tiny particulate matter, in the air approached 450, considered hazardous.
Experts said the burning of crop residue at the start of the winter wheat-planting season is a key cause of the pollution.
Lahore was once known as the city of gardens, which were ubiquitous during the Mughal era of the 16th to 19th centuries. But rapid urbanisation and surging population growth have left little room for greenery.
