this may well be an ongoing concern
http://www.sciencedaily.com reports dated 8 FEB that pollution is an ongoing health risk the story title is "exposure to pollution 30 years ago associated with increased risk of death "
the research was done by imperial college London following 368,000 people in England and Wales from 1971 to 2001
there is a link to the paper in an open access journal
the principle findings are
- the major health risk of pollution is respiratory disease, cardiovascular disease is also involved
- the most important influence is recent pollution, however past exposure have some influence
- pollution is measured in units of 10 micrograms per cubic meter of air , for each unit of added exposure in 1971 , there was an 2% increased risk of death in the period 2002 to 2009
- more recently there was a 24 % increased death risk in 2009 to 2009 for each extra 2001 pollution risk
- overall the risk of death is 14% higher in a high pollution area than in a low pollution area
- British pollution levels are going down the 2001 black smoke levels are 20 % of the 1971 levels
- the overall death risk from pollution is considered low when compared with other medical and lifestyle factors
comparing things to China I have serious doubts if there will be excellent kept long term records of pollution levels or any great decrease in pollution
also a mentioned before the health impact will be worse as the ongoing pollution will limit the possibilities for outdoor exercise
