Do you know the Air Quality Index(空气质量指标) or AQI report in the newspaper? The AQI helps us understand what the air quality around us means to our health. The AQI uses colours, numbers and words to tell us about the air. What do these colours and numbers mean? Let’s have a look.
AQI Colours | AQI Numbers | Health Word(s) |
Green | 0—50 | Good |
Yellow | 51—100 | Moderate(适中) |
Orange | 101—150 | Unhealthy for sensitive(敏感的) groups |
Red | 151—200 | Unhealthy |
Purple | 201—300 | Very unhealthy |
When the AQI colour is green, just enjoy the clean air!Yellow shows the air quality is fine for most people. Orange tells us people with lung disease(肺病) should spend less time outdoors. When the AQI colour is red, people with lung disease and active kids and adults shouldn’t spend too much time outdoors. Everybody else should try to spend less time outside. Purple shows everybody should try not to go outside.
