China’s air is flooded with tiny particulate matter (PM2.5) that endangers health. The World Health Organisation (WHO) “guidelines suggest that PM2.5 levels above ten micrograms per cubic metre are unsafe.” Almost all of China is above this level. ”Indeed, much of the country’s population endures air so foul that it registers above 30 on the PM2.5 scale, with Shandong and Henan provinces topping 50.”
