Chengdu, China, is experiencing rapid economic growth and urbanization at a cost of serious air pollution problems. China has developed a series of policies to reduce PM2.5 emissions and to reform energy structure. However, problems exist which may prevent effectively implementation of the PM2.5 policies, include poor PM2.5 monitoring, isolated environmental management, lack of health improveme...

Scientific efforts to understand the health effects of air pollution and public policy efforts to control air pollution have a fascinating history. The early “killer smog” episodes in Meuse Valley, Belgium (1930), Donora, Pa (1948), and London, UK (1952) provided stark evidence of deleterious respiratory and cardiovascular health effects of severe air pollution exposure. This evidence motivated...
