Very high air pollution looms in Hong Kong
Bad news at all three roadside-monitoring stations.
The Environmental Protection Department said the index was 122 at the Central Business District and 119 in Causeway Bay as of 7 a.m. yesterday. The reading in Mong Kok was 106.
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.
