Pollution 'ignored' in past
Under popular pressure that has been building since last year, Chinese environment authorities in Beijing have agreed to publish PM2.5 data. But they maintain the air quality has improved steadily in recent years.

“We may have had bad pollution in the past, but people probably didn’t pay too much attention to it before so it was just ignored,” said An Xinxin, who works in the Automatic Monitoring Office at the Beijing Environmental Protection Monitoring Center.

The Center relies on anywhere from 30 to 40 monitoring stations. “Almost every district and county in Beijing has its own station,” explained An. “So citizens in every district and county can know what the pollution in their own area is like.”

Like many of his colleagues at the municipal level, An pointed out that the U.S. embassy only uses one monitor. “[It] can only represent one spot at a certain time. Their spot might be very close to the road where there is a lot of vehicle exhaust, which causes a high level of PM2.5,” he said. “Our statistics are an average of Beijing as a whole, not just one spot.”

Zhang has lived in Beijing for more than ten years, but he said he’s not sure whether the air quality has improved or not. “I don’t know if it’s because now I pay more attention [because of the media and online discussion], or if it’s because the air quality has worsened,” he said.

But he and Wang dreamed up the idea of incorporating both the Chinese and American data streams into their app.

On Monday this week, they introduced a 2.0 version that not only posts real-time data from the U.S. embassy in Beijing and U.S. consulates around China, it also includes data from the Chinese Ministry of Environment’s monitoring centers in 120 cities across the country.

Also available in English, the app has been downloaded nearly 5,000 times.

“We thought it was good to include both. In some cities, users might want alternative information,” Wang said. “If there were a third source for air pollution data, we’d probably include it in the app, too.”

They might also want to add Hong Kong to their list of cities.

This month, a local nongovernmental group said Hong Kong’s air is 20 per cent more deadly than the air in mainland China.

Using data from Hong Kong’s own government and the World Health Organization, the Clean Air Network ranked Hong Kong ahead of mainland China, India, Vietnam, and Bangladesh for its high air pollution mortality rates.
