Back To Normal! Post APEC, Beijing Air Quality Index At 296 Per US Embassy ("Very Unhealthy")

Beijing's stunning but temporary clear skies finally gave way to choking smog yesterday, despite President Xi Jinping's pledge to preserve "Apec blue" - the term Beijingers coined to describe the impact of short-term curbs on air pollution. The capital's official average air-quality index (AQI) stood at 201 at 5pm yesterday, while the reading released by the US embassy reached 296, officially described as "very unhealthy" bordering on "hazardous".

Beijing enjoyed "excellent" or "good" air quality - an AQI reading of below 100 - for all but one of the first 12 days of this month, in sharp contrast to smog-ridden October when heavy pollution cloaked the capital four times, according to the Beijing Environmental Protection Department.

According to the website Weather.com.cn run by the China Meteorological Administration, "light to medium" air pollution covered parts of northern China yesterday, as a result of still weather that prevented pollutants dispersing.

Yesterday's pollution ended the two-week run of clear skies in the capital. Smog controls in the city and surrounding regions were lifted on Wednesday, the day after the Asia-Pacific Economic Cooperation summit ended. Factories and construction sites resumed operations and private cars returned to the roads.
