Chengdu is affected by smog sometimes. The concentration of PM 2.5 particulates is an important indicator of air quality. Monitoring agencies convert the concentration of PM 2.5 particulates into an air quality index (AQI) to reflect the air quality. According to the Technical Regulation on Ambient Air Quality Index (on trial) released by the Ministry of Environmental Protection (MoEP) of the People’s Republic of China (Announcement  No.8), AQI in the range 0-50 indicates good air quality; AQI in the range 51-100 indicates moderate air quality; AQI in the range 101-150 indicates light air pollution; AQI in the range 151-200 indicates medium air pollution; and AQI in the range 201-300 indicates heavy air pollution; while AQI in the range 301-500 indicates serious air pollution. MoEP suggests that if AQI exceeds 200, people with heart or lung diseases, the elderly and children should consider refraining from outdoor activities and taking precautionary measures such as wearing face masks when going out and installing air purifiers indoors.
Chengdu Municipal Environmental Monitoring Centre forecasts the air quality in Chengdu on a daily basis and issues alerts in case of heavy air pollution. In terms of level and duration of pollution, there are four levels of alerts: Blue (Level 4), Yellow (Level 3), Orange (Level 2) and Red (Level 1), with Red being the highest level of alert. People travelling and living in Chengdu should pay attention to announcements on air quality in Chengdu and the related precautionary measures by other relevant institutions or organisations.
