Air Pollution in China: Real-time Air Quality Index Visual Map
Cautionary Statement (for PM2.5) 0 - 50: Good: Air quality is considered satisfactory, and air pollution poses little or no risk: None: 51 -100: Moderate: Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
