Why is the air quality in Wuhan so bad?

There are many construction sites, many vehicles and heavy dust in the city.

1. Many construction sites: Wuhan is a fast-growing big city with many construction sites. A lot of dust and particles will be produced during the construction process, which will have a certain impact on air quality.

2. There are many vehicles: As a transportation hub city, Wuhan has many vehicles and road congestion is common. High-density traffic leads to an increase in automobile exhaust emissions, including harmful substances such as carbon dioxide, carbon monoxide and particulate matter.

3. Urban dust: Affected by urban construction, road construction and dry weather, dust problems have appeared in some areas. These tiny particles are suspended in the air and spread with the wind, which will cause smog or reduce air quality.
