Effects of Plateau Air Quality and Low Oxygen Content on ...
ABSTRACT In 2020, the monitored AQI (Air Quality Index) in plateau—Tibet varied from 24 to 98 and averaged 48, while the PM2.5 concentration ranged between 3.0 and 31 µg m–3 and with an average of 10 µg m–3. The plateau—Tibet, had a good air quality, but with a lower atmospheric pressure and low oxygen concentration. As the important characteristic of …
