The good doctor in Beijing recently conducted a new air pollution survey around the city, comparing indoor and outdoor pollution, and the effects of things like air purifiers.

There’s also an air pollution Q&A with another doctor in Beijing about the actual effects on healthy people and when and where to exercise.

What “500″ means:

150+ = “Unhealthy”, 200+ = “Very Unhealthy”, 300+ = “Hazardous”. So what are we supposed to call it when it maxes out the scale?

Of course, you might be wondering what the Ministry of Environmental Protection was reporting at the same time:

The Chinese version site had the same:

As we couldn’t see down the street today, I don’t wonder who’s numbers are more accurate. However, three things you need to know about comparing pollution numbers:

1. Part of the reason for the discrepancy is that China doesn’t monitor the smaller, more harmful forms of air pollution.
2. It also helps that they shifted the location of their monitoring equipment to get better averages and record more “blue sky days”.
3. Measurement scales vary from country to country. You can see how China’s pollution scale compares to those of Honk Kong and the U.S. here: API and PM10 – health and here: Using the Beijing Air Quality Index (AQI) – Part I. These are also helpful (Wikipedia): Air Quality Index and Air Pollution Index. This site has a convenient widget that lets you compare China’s interpretation of its current pollution levels with that of other countries.

On days like this you can smell it as soon as you open the front door and see it just by looking across the street.

All these photos are from out our kitchen yángtái windows. The blue sky photos are from Oct. 1st; the less-blue ones are from this morning.

When we flew in to Beijing on Sept. 30 we could barely see the terminal from the airplane on account of all the kōngqì wūrǎn (空气污染). But not to worry, in China the They can change the weather. When there’s an important made-for-TV event, They make it rain the night before and… voila!:

That was Oct 1st, the even-more-important-than-the-Olympics 60th anniversary national day military parade. And this next photo was from this morning — apparently They didn’t have any photo-ops scheduled today:

Pollution is measured here in term of “blue sky days” (蓝天). True to form, since reality in China is whatever They say reality is (you really ought to read 1984), “blue sky day” doesn’t actually mean that the sky is blue or clear; it means the official pollution readings are below a certain level, which often is still thick with haze. And never mind that the cut off line for blue sky days is still considered hazardous by the rest of the world’s pollution monitoring scales, or that They don’t even bother measuring the most harmful forms of air pollution particles. In this last photo, you can see the colour starting to change in the top left corner; there were no clouds today, and if you looked straight up, you could actually see some faint blue.

P.S. – I think I’m just about done whining about the pollution, at least for now. Posts on karaoke survival, creative ways to stay connect with family back home, Tianjin’s suspiciously curvacious public statues, free One Child Policy baby accessories, and a racial Disney moment at the English school are all in the works.

And please, by all means, you’re welcome to add adjectives to my list (but keep it PG!). Sometimes it just feels good to vent to get it off your chest, especially since you can’t vent to get it out of your chest.

I’ll add a photo later if I can bring myself to take one (through tears, no doubt).

• Years shaved off my life due to the air pollution: incalculable

Five days a week I bike half an hour one way to work; so 13.2 kilometers total there and back according to google maps. The numbers above are only for the morning commute to work. There really was a car on fire this morning.
