Hong Kong Air Pollution ‘Very High’ in Central, Causeway Bay

Hong Kong’s Air Pollution Index was “very high” at two of the city’s roadside-monitoring stations, according to data from the Environmental Protection Department’s website.

The index was 138 in the Central business district and 110 in Causeway Bay as of 8 a.m. local time. The reading in Mong Kok was 87. A reading of more than 100 triggers a government warning for people with heart or respiratory illnesses to avoid prolonged stays in heavy-traffic areas.
