Hong Kong Smog Hits Serious Health Risk LevelsHong Kong Smog Hits Serious Health Risk Levels

Air pollution in Hong Kong hit some of its worst levels on Monday, posing a serious risk to residents’ health for the second time in just five days.

The Environmental Protection Department reported that smog levels at a monitoring station reached 10+ on the Air Quality Health Index, corresponding to the “Serious” health risk level, South China Monitoring Post reported.

That was only five days after the city got its most recent warning over breathing risks.

When the index reaches the “Very High” range, the public is advised to reduce outdoor physical exertion. When it reaches “Serious”, people should minimize their time outdoors.

The Education Bureau called on schools to take appropriate measures to safeguard pupils’ health.

The environmental authority said Hong Kong was having a hazy day with light winds, and that weather had caused a buildup of air pollutants in the city and the Pearl River Delta region since Sunday.

Recent sunny periods had enhanced smog activity and the formation of ozone and fine particulates, resulting in high pollution.

In parts of urban areas and on roadsides, nitrogen dioxide was forming because of the high level of ozone, which was the main reason behind the air quality’s deterioration to “Serious”.

The Hong Kong Observatory forecast that pollution levels would ease as an intense northeast monsoon started to affect the south China coast in the middle of the week.

General air quality monitoring stations hit “Serious” levels on an average of five days last year, up from three in 2016 and 2015, and four in 2014.

Tung Chung and Tuen Mun got the worst of it, with 12 and 13 days of “Serious” health risk respectively.
