In the previous two days, Hanoi's air quality had improved, with AQI was mostly at good and average levels at all ten monitoring stations.
The whole city was covered by thick fog on February 6 morning. Head of Hanoi's Environment Protection Authority Mai Trong Thai explained that this was a form of misty stratosphere.
The thick fog concentrated the fine dust, thus, Hanoi's AQI increased to the bad level.

The AEP recommends sensitive groups including children, the elderly and people with respiratory diseases should limit their time outdoors.
In case of going out, people should use PM2.5 standard dust-proof face masks. In particular, pupils should not participate in outdoor activities.
When travelling on roads, people need to strictly follow traffic laws to reduce traffic congestion.
People should reduce activities that cause air pollution such as burning waste, cooking by charcoal stoves, transporting construction waste without shielding.
