Quick note on Pollution in Beijing

I was thinking about comparing the lung cancer rates due to pollution in China to the lung cancer rates in the US due to pollution so I could try and figure out how much the poor air quality actually affects DALYs. After a quick google search I decided that that was probably an impossible feat even if the data were out there because of so many ifs in the reporting. Firstly, I'm sure that most cancers in China go unreported (and probably in the US too) because so much of the country is developing
without access to adequate health care. Secondly, more people in China smoke
than in any other part of the world (it's probably not so good for my second hand smoker's lungs) so the rate of lung cancer is going to be higher than the US regardless of pollution. Where's Poland's anti-smoking campaigns when we need them? Today the US epa lists the pollution as unhealthy but we could see the nearby buildings so everyone around me says it's a good day. Yesterday was a bad day, It was miserable to play frisbee in...in 95 degree heat on top of it. Out of curiosity I just looked up what the particulate matter level is for Chicago. I mean, it can't be so good, we allow trucks to drive around during all hours (in Beijing they are only allowed in the city at night), there are buses emitting particulate matter all day and night, and industry still happens there even if it's not at the level of Beijing industry. For a quick comparison: EPA says that Chicago is <50 which is an actual good value while Beijing averaged at 166 "unhealthy" for the day. Soon environmental standards will take control here I hope...although that still won't solve the smoking problem.
