A labourer works atop a building in Hefei in a haze day, Anhui province, January 14, 2013. Chinese media said on Monday the government had to take urgent action to tackle air pollution, which has blanketed parts of the country at dangerous levels in recent days, and one newspaper called for a re-think of a "fixation" on economic growth.
