Worst smog of the year prompts Hong Kong government health warning

Date of Release: 
Jun 9 2014

Hong Kong choked on its smoggiest day of the year so far yesterday as a trough of low pressure left the city coping with pollution that represented a "serious risk" to health.

At 7pm and 8pm, all 12 of the city's general pollution monitoring stations and all three roadside stations recorded pollution levels posing a "very high" or "serious" risk to health. All but two general stations and all of the roadside stations were at level 10+, the highest level on the government's Air Quality Health Index (AQHI), introduced last year.
