Over the past few years living in China, the air pollution conundrum (among many development issues) has been a major concern for expats and locals alike. Just last month (October 2013) an “airpocolypse” shrouded the city of Harbin in northeastern China at a level of around 1,000 micrograms per cubic meter! That’s off the charts and about “40 times the safety level recommended by the World Health Organisation” reports the Guardian newspaper.* Obviously this is (and will be) a major cause of lung cancer in the future, along with the effects of circa-1950s attitudes toward smoking.
