Here's a Beijing fun fact. This mornings air quality index was 562. Hm, just a number, I wonder what that means? So I checked out the handy scale the government (US, that is) put out about the readings.
Air Quality Index (AQI) Values) |
Levels of Health Concern |
|
| When the AQI is in this range: |
...air quality conditions are: |
|
| 0-50 |
Good |
|
| 51-100 |
Moderate |
|
| 101-150 |
Unhealthy for Sensitive Groups |
|
| 151 to 200 |
Unhealthy |
|
| 201 to 300 |
Very Unhealthy |
|
| 301 to 500 |
Hazardous |
|
What happens after 500? It doesn't say. I had often wondered until I saw the numbers today. Here's the AQI twitter feed:
11-19-2010; 02:00; PM2.5; 562.0; 500; Crazy Bad // Ozone; 0.1; 0; No Reading
That's right, our Beijing's air quality is now officially crazy bad!
