Remarks:

(1) The AQHI information is based on real time data taken directly from EPD's Air Quality Monitoring Network.

(2) Time shown is in Hong Kong time.

(3) The hourly reported AQHI is for short term health risk communication; for health risks of long-term exposure of the air quality, please refer to the Annual Air Quality Index(Annual AQI).

(4) In case of station or equipment suspension due to maintenance, the data collection for calculation of AQHI at station will be affected, the data of most similar stations will then be adopted. Such AQHI will be shown in italics.

(5) Owing to failure of power supply, the operation of Tap Mun general station has been suspended until further notice. We apologize for any inconvenience caused.

(6) Owing to urgent repairing work, the monitoring of Eastern general station is temporarily suspended until further notice. Regret for any inconvenience caused.
