What is the air like in Chengdu and Shanghai?

Why are they all big cities? The air difference between Chengdu and Chongqing is so big.

There is no law that the air in big cities must be good. Look at Beijing and Shanghai again. The quality of a city is closely related to the local development, geographical location and history, which cannot be clearly stated in one sentence.

The air quality in Beijing is better than that in Shanghai.

Professor Zhuang Guoshun, an expert in PM2.5 research in China, said: We generally think that the air quality in Shanghai is better than that in Beijing. It can be said that it is at the level of PM 10, but at the level of PM2.5, the annual average of PM2.5 in Beijing is between 50 and 70, and that in Shanghai is between 40 and 70, which is basically the same level, not much better. In addition, it is worth noting that among the air pollution components in Shanghai, the components from human activities account for a high proportion. Specifically, the proportion of organic components in the air in Shanghai is very high, and the proportion of heavy metals is also very high, both of which are carcinogens PM2.5 So the air in Shanghai may be more toxic than that in Beijing at the same concentration. In fact, the incidence of lung cancer in Shanghai is very high, which is related to this.

As a Sichuanese ~ I still want to say that Chongqing is good ~ I want to say two details. First, when taking a taxi in Chengdu, the driver must ask where you are going.

I like Chengdu. The urban environment of Chengdu is close to that of the big cities in the 1980s. The trees are green and the natural environment is primitive. The architectural design is simple and generous, with harmonious and beautiful colors, beautiful scenery and good air quality. I sent some photos of cities in the 1980s, and the environment in the 1980s was neither new nor old. & gt

Why is there no smog in Shenzhen, but the smog in Chengdu is so serious?

First of all, let's understand the causes of smog. The visual obstacle caused by solid or liquid particles suspended continuously in the air is smog. Shenzhen is a high-tech city with less heavy industry. In addition, it is located in the south, near the sea, and the air humidity is high. Suspended particles in the air are easy to settle in water, so there is less smog. Chengdu is located in the basin and is called the city of stoves. The weather is dry, particles are difficult to settle, and there is more smog.

Nowadays, air pollution is becoming more and more serious. We should not only pay attention to the harm of smog, but also pay attention to the prevention and control of other harmful gases. It is recommended to install a fresh air system at home to minimize the time outside. My home is decorated with five-degree and five-constant central air conditioning, which can not only cool and heat, but also control the indoor air at constant temperature, humidity and oxygen, which is very good.

Why are there no big cities in the northwest? Xi is far from Chengdu and Chongqing.
