A thick smog hung over the residents of the city of Harbin, one of China’s largest cities. Visibility dropped to less than 50 meters in some areas of the city, causing the closure of schools, bus routes and Taiping International Airport in Heilongjiang province.
Air pollution in China is an ongoing issue. According to Reuters "An index measuring PM2.5, or particulate matter with a diameter of 2.5 micrometers (PM2.5), reached a reading of 1,000 in some parts of Harbin, the gritty capital of northeastern Heilongjiang province and home to some 11 million people. A level above 300 is considered hazardous, while the World Health Organisation recommends a daily level of no more than 20."
For China's residents smog is an ever present reality. This becomes particularly bad during the cold winter months as the country's coal plants are fired up to warm the homes of nearly half a billion citizens in the north.
