Tung Chung air quality once again has reached the most hazardous levels on the government air quality index.
From 4pm-7pm Wednesday, air quality reached 10 and 10+ on the EPD’s Air Quality Health Index (AQHI).
It remained at 10+, the highest level, for more than an hour. At that level the EPD urges people to restrict outdoor activity to the minimum and for children and the elderly to stay indoor.
The index reading for the district remained low this morning, but with a warning of possibly high health risk this afternoon.
It is the second time in 12 days that Tung Chung air has hit hazardous level, a combination of high temperatures and low winds.
The HK Observatory has issued another very hot weather warning today, predicting temperature could reach 35. The temperature at Chek Lap Kok at 10am was 32 degrees.
