Beijing is periodically hit by choking, acrid haze, with particulate levels jumping far beyond recommended limits/AFP
BEIJING, Jan 15- Pollution levels soared in Beijing on Thursday to readings more than 20 times WHO recommended limits, as an annual bout of intense smog returned to haunt the Chinese capital despite government vows to address the plague.
Levels of PM2.5 particulates — the smallest and most dangerous, with a diameter small enough to deeply penetrate the lungs — were recorded at 568 micrograms per cubic metre by the US embassy during the afternoon.
An even worse reading of 631 was recorded at a municipal monitoring station in the east of the city.
The World Health Organization’s recommended maximum is 25 micrograms per cubic metre.
China has for years been hit by heavy air pollution, caused by enormous use of coal to generate electricity to power a booming economy — the world’s second largest — and more vehicles on the roads.
Beijing is periodically hit by choking, acrid haze, with particulate levels jumping far beyond recommended limits.
The phenomenon tends to be at its worst in winter, when demand for electricity rises for heating.
Authorities warned earlier this week of smoggy weather blanketing northern China, blaming calm weather as windy conditions tend to disperse pollution.
Thursday’s spike — levels were beginning to reduce in the late afternoon — came almost exactly two years after an extreme bout of bad air in January 2013, dubbed the “airpocalypse”, when state media reported readings at nearly 1,000 micrograms per cubic metre, almost 40 times the WHO’s limit.
Public discontent about the environment has grown, with pollution a popular discussion topic on social media.
The official news agency Xinhua reported Thursday that Rao Bing, a local environmental official in Dazhou, in the southwestern province of Sichuan, had been excoriated online after blaming smog in the area on residents smoking bacon.
“The people who discovered this should win a Nobel,” sneered one poster on Sina Weibo, a Chinese equivalent of Twitter.
Preserved pork and sausages are traditional Sichuanese foods, with many households smoking their own ahead of the lunar new year.
The central government has declared a “war on pollution” and vowed to cut coal use in some areas, although it has only pledged a goal of greenhouse gas emissions peaking “around 2030”, suggesting they will rise for more than a decade.
