China's financial centre continues to be haunted by one of its worst-ever bouts of air pollution, bringing visibility down to a few dozen meters and obscuring the city's spectacular skyline.
According to the local meteorological centre, Shanghai saw levels of PM2.5, or particulate matter with a diameter of 2.5 micrometers, reach 602.5 micrograms per cubic metre last week. This is the highest since December and the city's air pollution has hit the 'extremely hazardous' level as compared to the World Health Organisation safety limit of 25 micrograms.
The constant pall of yellow haze gripping the bustling city of 23.8 million people is mostly attributed to coal burning, factory pollution and car exhaust fumes. Shanghai usually experiences reletively mild air pollution thanks to its coastal location, but recent weather patterns has resulted in stagnant air in the city and aggravated the situation.
Heavy smog has been lingering in parts of northern and eastern parts of China since last week, obstructing the traffic and forcing the closure of schools. Conditions are even worse in neighbouring provinces like Jiangsu and Shandong and the government has already raised the red alert, advising people to take necessary precautions and suspending outdoor activities.
