Remarks:
(1) Time shown is in Hong Kong time.
(2) Concentration shown is in microgram per cubic metre (µg/m3).
(3) Abbreviation:
NO2 - nitrogen dioxide, O3 - ozone,
SO2 - sulphur dioxide, CO - carbon monoxide,
PM10 - respirable suspended particulates,
PM2.5 - fine suspended particulates
(4) The Pollutant concentration and AQHI information are based on real time data taken directly from EPD's Air Quality Monitoring Network.
(5) In case of equipment or station suspension due to repair and maintenance, the data collection for calculation of AQHI at station will be affected, the data of similar stations will then be adopted. Such AQHI will be shown with an asterisk.
