 US Embassy In China Set Up Its Own Air Monitoring System
The US embassy in Beijing has set up its own air monitoring station out of concern for the health of its staff.

The embassy has been releasing its own private air quality reports since last year, which differ significantly from the ones issued by the Beijing Government, spokesperson Susan Stevenson said in an interview last week with Canwest News Service.

People can check the air quality near the embassy on a Twitter feed called BeijingAir, with the latest information updated every hour, the China Daily reports.

From 1 a.m. to 2 p.m. on Tuesday, the air quality was unhealthy, according to the embassy monitoring station, while the capital's environment protection bureau said that the average air quality yesterday in Chaoyang district, where the embassy is located, was "moderate".

The air quality for June 18, when the sky was murky at noon, was slightly polluted, according to the official data, but the result was different on the BeijingAir Twitter, with the hourly measure creeping into the "hazardous" range for seven hours.

The China Daily calculated that only five days were above "moderate" level in May on BeijingAir, but the local environment bureau said on its website on May 31 that the capital's air quality was the clearest during the same period since 2000, with 25 blue-sky days.

"This is a single site. It cannot be used to measure the air quality across the city. They can't be compared," Stevenson said.

Li Xin, chief engineer of the municipal environment protection bureau, said yesterday that the bureau has 27 monitoring stations across the city and publishes average air quality data every day.

"The embassy is located in the central business district, which has heavy traffic, and its monitoring station cannot represent the overall picture," Zhu Tong, an environment professor with Peking University, said.
