for Hong Kong and Mainland China in real-time
The Hedley Environmental Index monitors and publishes in real-time the economic costs of Hong Kong's air pollution in terms of public health impacts and their monetary value. The public health impacts include premature deaths, hospital bed-days and doctor visits.
The AQHI informs you of the short-term health risk of air pollution and helps you take precautionary measures to protect your health. The AQHIs are reported on a scale of 1 to 10 and 10+ and are grouped into five health risk categories.
