Since early morning on November 4, Hanoi has been covered in a thick layer of fog, making high-rise buildings and apartment complexes obscured in a white mist. The fog not only obscures visibility but also affects people's health due to the high level of air pollution.

At 6:30 am at Cau Giay intersection, the sky was covered by a thick layer of fog. According to local residents, this foggy condition has lasted for many days.

Lotte Tay Ho building is obscured by opaque white.

According to the Department of Environmental Pollution Control, from September of the previous year to March of the following year is the "season" of air pollution in the Northern Delta provinces, especially in Hanoi and neighboring provinces.

On the IQAir website, the AQI air quality index in Hanoi at 9am on November 4 was 195 - reaching an unhealthy level, recommending people wear masks when going out.

Seen from above, rare green areas such as parks and gardens are clearly areas less affected by pollution and fine dust thanks to their natural dust filtering ability.

The road along West Lake is still covered in a thick layer of fog at 7:30 am, the sun is still not visible. People exercising must wear masks to protect their health.

The Department of Environmental Pollution Control has pointed out that motorbikes, cars and other vehicles emit CO, NO₂, and fine dust particles (PM2.5, PM10), leading to a decline in air quality, especially in densely populated cities like Hanoi.

At 8:30 a.m., an old motorbike emitted white smoke while moving on Au Co street.

In addition, open burning of garbage, use of honeycomb coal, and other activities also emit many pollutants, contributing to increasing air pollution levels. (Image recorded on Vo Chi Cong Street at 9am this morning).

The city sky was gray.

The Department of Health Environment Management ( Ministry of Health ) recommends that when the air quality index is at a bad level (AQI from 150 to 200), people should limit outdoor activities or participate in strenuous physical activities.

Hanoi's air quality map this morning shows red to purple, indicating a risk of severe pollution.
