Hanoi sky is hazy on the day of air pollution among the top in the world

For nearly a month now, Hanoi has been experiencing turbid air and hazy skies from early morning until almost noon.

In particular, on December 10, the capital's sky was hazy at noon (12:30).

According to information from the Air Visual application (which monitors air quality worldwide ), Hanoi's air quality index (IQA) is at 213, ranking 5th in the world. This is a very bad level, harmful to health.

Recorded at 12:50, in the Keangnam building area (Cau Giay district, Hanoi), fog and fine dust were dense. At this time, the air quality of Cau Giay district was at 167.

The top of the 350m high Keangnam building is shrouded in fog and dust.

The 63-storey Lotte Hanoi Building (Ba Dinh District) was covered in a layer of opaque white air, even though the reporter's observation position was only about 1km away.

Dr. Hoang Duong Tung, Chairman of the Vietnam Clean Air Network, explained that air pollution in Hanoi is partly due to emissions from vehicles.

According to statistics, Hanoi has 7.8 million vehicles, of which more than 1 million are cars and more than 6.6 million are motorbikes. Not to mention about 1.2 million vehicles from other provinces and cities participating in traffic in the capital.

Although Hanoi has been sunny in recent days, the sky is still hazy due to being covered by a thick layer of fog and fine dust.

At 1 p.m., buildings along the To Lich River were still hidden in a layer of fog and fine dust.

According to Dr. Hoang Duong Tung, fog usually appears from October to March of the following year. The reason is due to little rain, calm wind, fog combined with emissions from the ground that are not diffused, so they linger at low altitudes.

West Lake near Lac Long Quan Street on the afternoon of December 10 was still foggy.

Tay Ho District today has many times when the pollution index reaches 272. The AQI air measurement site recommends that people avoid exercising outdoors, close windows to avoid dirty air outside, wear masks when going out, and use air purifiers to protect their health.

From 2pm Hanoi had sunshine, the sky gradually cleared. By 4pm, the pollution index in Hanoi was 130, ranked 17th in the world.
