Dec. 23 (Bloomberg) -- Hong Kong’s new air quality index showed health risk was “very high” at the Central roadside- monitoring station, according to data from the Environmental Protection Department.

The index is calculated based on health risks from inhaling concentrations of ozone, nitrogen dioxide, sulfur dioxide and particulate matter. The government will implement the index on Dec. 30 and is releasing the data today on a trial basis.

The “very high” level of health risks triggers an advisory for the public to reduce outdoor physical exertion and reduce the time of stay outdoors, according to the government’s website.
