PM 2.5 fine dust is tiny dust particles in the air. When the concentration increases, the air will become hazy and visibility will be reduced, looking like fog. This is a dangerous level of pollution, affecting the elderly and children, causing respiratory diseases such as pneumonia, bronchitis, and respiratory failure. These people should limit going out if not really necessary.

According to experts, in addition to PM 2.5 fine dust, people burning straw at the end of September every year is also the reason why Hanoi is covered in fog.

In addition, the emission source does not decrease, the thick fog causes the dust in the air to be stored in the lower layers to diffuse more and more widely. The image of two apartment buildings in Xa La urban area is seen from a distance of several dozen meters.

Experts also recommend that in the dense fog there are fine dust and household exhaust fumes, impurities that irritate the respiratory system, causing difficulty breathing and more discomfort.
