I know I just talked about the pollution problem in Beijing but I just came across this graph. The reason why I entered a piece on smog was it just seemed so bad that day and had to write about it. Here is the proof of just how bad it was.
China's State Environmental Protection Administration (SEPA) has a pollution rating scale that measures up to 500. A 25 rating is considered safe. A 200 is a bad day for Beijing.

TF congrats to AF on her acceptance! Fantastic! For a data guy your graph presentation was lame - we have no concept for that "500" on the Y-axis!? Would a bad day in L.A. be a 25? a 200?... anyway, don't envy your lungs, you must have cut your ride short that day. Good luck in the playoffs see you in the Super Bowl.... TOB
The Insider’s guide to Beijing once published a statement of a Doctor from the Beijing United Family Hospital saying that you should avoid going outside when 150 mgr/m3 are reached.
Others see it even more critical. E.g., the Australian Department of Environment and the German Ministry of Environment aim for a daily maximum concentration of 50 micrograms of PM10 per cubic metre (level 1). In Germany every city is allowed to exceed this goal only 35 days per year while in Australia apparently only five days. So in Beijing do not look at the terrible ‘500’-days but look at all the bad days in 2006 when the ‘50’-goal was exceeded: Year to date, there were 347 polluted days in Beijing. Only 25 days where ‘healthy’ days.
