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

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

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 9:00 a.m. on November 4 was 195 - reaching an unhealthy level, recommending that people wear masks when going out.

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 thick fog at 7:30 am, the sun is not yet visible. People exercising must wear masks to protect their health.

The Department of Environmental Pollution Control has pointed out that motorbikes, cars and other means of transport 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 traveling 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 9:00 am this morning).

The city sky is 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.
