Air quality indices, at least measured in PM2.5 or PM10, seem to be closer to 200-600 for the overwhelming majority of places in Shandong (which I assume is what you meant), currently and for the past 48 hours. I could only find one place [0] exceeding 800. Those levels are already appalling, but your statement suggests that it is 'around 800' for the entire state/province, not that a few locations peaked at 800. 0: http://aqicn.org/city/shandong/caoxian/caoxianwenhuazhongxin/ http://aqicn.org/city/shandong/caoxian/caoxianwenhuazhongxin...
