Air pollution in Beijing has reached dangerous levels for a third
day. On Sunday, the municipal government issued a warning on its website
for PM 2.5 readings. Real-time monitoring data shows the air quality index was as high as 500 in most parts of the city, with some above 900. An AQI reading below 50 indicates excellent air quality; above 100 is light pollution.
The smog is expected to last another three days, as weather conditions are preventing the pollutants from dispersing. The public are advised to stay indoors and to avoid strenuous exercise.
