Lives without the sun in smog hell
BEIJING — Winter typically brings the worst air pollution to northern China because of a combination of weather conditions and an increase in the burning of coal for homes and municipal heating systems, which usually starts on a specific date. For the large northern city of Harbin, the city’s heating systems kicked in on Sunday, and on Monday visibility there was less than 50 meters (yards), according to state media.
“I couldn’t see anything outside the window of my apartment, and I thought it was snowing,” Wu Kai, 33, a housewife and mother of a baby boy, said in a telephone interview from Harbin. “Then I realized it wasn’t snow. I have not seen the sun for a long time.”
She said her husband went to work in a mask, that he could barely see a few meters (yards) ahead of him and that his usual bus had stopped running. “It’s scary, too dangerous. How could people drive or walk on such a day?”
The density of fine particulate matter, PM2.5, used as an indicator of air quality was well above 600 micrograms per cubic meter — including several readings of exactly 1,000 …. They were the first known readings of 1,000 since China began releasing figures on PM2.5 in January 2012, and it was not immediately clear if the devices used for monitoring could give readings higher than that.
A safe level under WHO guidelines is 25 micrograms per cubic meter.
