Hong Kong warned residents to reduce time spent outdoors under a new air-quality monitoring system implemented yesterday as the city seeks to counter criticism it’s not doing enough to combat pollution.
A roadside monitoring station in Causeway Bay reported air quality of 10 on a 10-point scale as of 2 p.m. local time, signaling “very high” health risks, according to the city’s air-quality health index website. When readings exceed the highest level, it triggers “serious” warnings and calls for children and elderly to stay indoors.
