Air Quality in China: A Snapshot
Nearly five weeks ago, Beijing experienced its worst day of air quality on record: Levels of PM2.5—small particulates that can cause lung, cardiovascular, and respiratory disease—soared to more than thirty times the level considered safe by the World Health Organization.

Since then, reporting on China’s “airpocalypse” has been accompanied by what seems like a monochromatic slideshow of the country’s iconic cities—Beijing, Shanghai, Tianjin—all smothered in thick smog.
Indeed, China’s most populous and prosperous cities are among the epicenters of this latest pollution crisis. In Tianjin, for instance, levels of PM2.5 hit 577 on February 9, the eve of the Chinese New Year. In Beijing, sales of New Year’s fireworks dropped 37% after the municipal government asked residents to limit their use.
Beijing’s air pollution regularly makes international headlines. But exactly how bad is the air in the Chinese capital, home to 20 million people? That’s the question China Air Daily strives to answer—in pictures we take every single day from the same spot.Air pollution…
But air quality in China is also a nationwide problem—a predicament that affects cities with far less name recognition than Beijing or Shanghai. Last week, the People’s Daily reported that of the seventy-four key cities monitored by China’s Ministry of Environmental Protection, all seventy-four reported “excessive” PM2.5 concentrations on February 10, the first day of the Chinese New Year.
And as a glance at pollution figures from this morning shows, hazardous air conditions remain in cities throughout China, from Urumqi (with a PM2.5 concentration of 511 micrograms per cubic meter, or twenty times the recommended limit) to Guangzhou.

Over the last few months the news and reportage about China have become almost incomprehensibly divided between two points of view. According to one set of reports, China is now confirmed as an economic “colossus,” shaking off all the trammels of the past, yearning to host...
1.Many Americans think they know something about Chinese food. But very few know anything about food in China, about the ways in which it is grown, stored, distributed, eaten, and wasted, about its effects on the country’s politics, and about its importance to the rest of the...
The last time I was in the Himalayas, I met a young, highly Westernized Tibetan who, misled perhaps by my Indian features (born in England, I’ve never lived in the subcontinent), started talking to me about the strange ways of the exotic foreigners he saw all around him. “...
