Why is the air quality in Wuhan so bad?

The reasons for the poor air quality in Wuhan are as follows:

1. Digging all over the city, there are construction sites everywhere, and the ones that should be demolished should be demolished again, and the ones that should not be demolished should be rectified. The unfinished projects are everywhere, the construction waste is piled up, and the roads where cement tankers run are dusty. It takes a long time to calm down.

2. Wuhan is a large city, with a large population and many vehicles, and it does not adopt the restriction policy. There are all kinds of cars on the roads, some of which have reached the end of their life, and the owners are still driving, so the exhaust emissions should not be underestimated.

3. Wuhan is a heavy industrial city, including WISCO, Wuhan Petroleum and Wuhan Pot. If you want to develop, you must make sacrifices.

4. It's still traffic. There are only two subways. Road traffic is really difficult to meet people's needs. If there were more underground construction, there wouldn't be so much exhaust.

5, because of the long drought and no rain. Since autumn, there has been no heavy rain in Wuhan except for a few sporadic light rains. The ground is very dry and dusty as long as it blows. Therefore, the air quality is affected.
