Pakistan's Lahore Chokes on Toxic Smog

Thousands of citizens of Pakistan's Lahore, one the world's most polluted cities, complained Thursday of breathing difficulties and irritable eyes as a blanket of thick smog was forecast to persist for several days.

Readings of dangerous "fine particulate matter" were more than four times the World Health Organization's recommended level, exceeding 104 micograms per cubic meter of in the worst-hit parts of the city of around 10 million. 

Visibility plunged to less than 20 meters and citizens wore face masks to help with breathing.

Nasimur Rehman, a senior official in the Environment Protection Agency blamed the pollution on less-than-average rainfall over the Punjab region, traffic standing still through various points of the city, and tire-burning factories located to the city's north.

Separately, at least 13 people were killed and nearly 100 wounded in two pile-ups involving 16 vehicles on the Lahore-Islamabad motorway due to dense smog, local police official Aslam Gondal told AFP. 

The first collision was between two trucks and a bus, accounting for most of the casualties, while the second pile-up involved multiple cars.

Kashif Hussain, a 34-year-old cattle market worker, told AFP: "The smog has been going on since yesterday and I had to take the day off work today because my eyes have gone red. 

"It's been very severe and I was prescribed drops by my doctor," he said. 

"Toxic smog blanketing Lahore, air quality deplorable," tweeted resident Sabrina Toppa.

So-called fine particulate matter are particles 2.5 micrometers in diameter or smaller produced by combustion, and some industrial processes. They are linked to eye-irritation, coughing, asthma and even heart attacks as well as premature death.

A United Nations last week reported some 300 million children live with outdoor air so polluted it can cause serious physical damage, with the situation most acute in South Asia.

"Pollutants don't only harm children's developing lungs. They can actually cross the blood-brain barrier and permanently damage their developing brains and, thus, their futures," said Anthony Lake, executive director of UNICEF.
