What is it like to live in a city with a lot of smog?

The feeling of hell on earth.

Going to school in central Shandong, the summer is better, and in the winter, when it is serious, the surrounding environment is the same as milk, take a few breaths of air, sore throat is not that I am not patriotic, we should indeed be the air quality should be whole, but not many people care, playing in heavily polluted weather, running a little bit, alas, I wipe, these young people.

I have been living in Hebei before, the haze level is more outrageous than the above **, and what is even more hateful is that there are people who interfere with the monitoring table, so that the measured value is low, of course, the low is also explosive, but it is a question of 800 or 500. It's been gone for a few years, and I heard that it's the conquest that serves the people, and the governance is particularly good. The haze makes me feel crazy.

What makes you even more incomprehensible is that many people don't take it seriously at all. Every day in the haze, you should run, run, and dance.

Want to escape forever, this hellish place.

I feel very depressed, and I feel that there is no point in struggling! I want to escape every day.

More than 30 years ago, the results of reducing smog have been studied, and the Cangzhou Sea Wharf was built before the burning of the "two-story test building to reduce haze", which can achieve fifteen functions such as heating without spending money

Hangzhou. In addition to summer, in fact, there are three seasons of rain and snow. The rest are basically smog days. As long as you go out, you have to wash your hair, and you don't dare to open the windows at home.

Why are housing prices still so high in Beijing? Living in Beijing will be a long life! One of the cities with the worst smog.

One winter in Xi'an, it was basically smog every day. In severe cases, it is smog and dust, and the sky is full of loess. Voice. No, my nose is often runny. You can't even prevent it with an anti-smog mask.

It feels very bad to live here, irritable, and nostalgic for the blue sky of the past.

Living in a city with severe smog is the kind that is inconvenient in all aspects.

It's very uncomfortable, I wash my face and nose every day and go out, and when I come home, I will be disgraced.

Living in a city with severe smog, the essential thing every day is a mask, for fear of being poisoned by the smog that day.

When I live in a city with a lot of smog, I feel that the whole city is a haze, and I know that the weather is very bad.

During that time, I was really scared that I would get a terminal illness, but now I have improved a lot.

Living in a city with a lot of smog can make it difficult for you to breathe and hinder your daily travel.

Living in a city with a lot of smog and breathing heavily polluted air can feel very uncomfortable.

If I live in a city with a lot of smog, I choose to go out with a mask.

Living in a city with a lot of smog should be a very bad experience, because the air quality is relatively poor, and you need to wear a mask every day when you go out.

Living in a city with a lot of smog means that I feel that the whole life is very special and boring.

In fact, there are too many cars!

Which city is the most smoggy? The topography of Xi'an is high in the north and low in the south, and the south is because of the barrier of the Qinling Mountains, the pollutants are not easy to diffuse after they are formed, and they will gather in the urban area and not easy to disperse. People who live in Xi'an also know that there are fewer winds in Xi'an throughout the year, and the cold air is not very active, which is also detrimental to the diffusion of pollutants.

We all know that the ridicule is that the control of haze mainly depends on blowing, and this blowing I think is the dispersing power of wind and cold air. In addition, Xi'an is located in the northwest, and further northwest along the Hexi Corridor will reach Ningxia and Gansu, where there are many sandstorms, and the dust will also spread to Xi'an along the Hexi Corridor.

There are many industrial enterprises gathered around the urban area of Xi'an, and the dust pollution caused by winter construction, some people joke that Xi'an people love to eat oil and splash noodles, which will also cause an increase. In short, the superposition of all these unfavorable factors has made Xi'an's smog more serious, and our intuitive feeling is that Xi'an's smog days this year seem to be more serious than last year. Geographical environment.

Fog and haze are twins, and their formation requires cold, humid and windy natural conditions. Xi'an is located at the northern foot of the Qinling Mountains, a typical northern city, with cold winters; The rainy season is concentrated in autumn, with continuous autumn rains, low evaporation, and a lot of water accumulated in the soil; Although the northwest wind prevails in winter, it is blocked by the Qinling Mountains and the circulation is not smooth.

Topographic factors. The Guanzhong Plain is bordered by the Qinling Mountains in the south, the Loess Plateau in the north, and the mountains and hills in the east and west, with low-lying terrain and weak winds, and the surrounding pollutants are easy to be blown into the sediment by the wind, but not easy to discharge. Xi'an is an important national defense industrial base, the urban area is full of high-rise buildings, the surrounding thermal power plants, heavy industry, building materials industry more, coupled with winter central heating, coal consumption is larger, natural gas combustion is insufficient, and it is easy to emit exhaust gas, waste gas, rural firewood and grass boiling water for cooking, winter coal heating, breeding pollution, garbage dumping is also a reason, but compared with industrial pollution, waste gas, waste water and waste discharge, etc., the impact should be minimal.

High-rise buildings are dense and poorly ventilated, resulting in hot summers (urban heat island effect) and smog in winter.

The cities with more serious smog are Beijing, Tangshan, Fushun, Dalian, Baoding, Shijiazhuang, etc., which should be for the development of industry and exhaust emissions, resulting in serious haze and serious air pollution.

I think it's Shijiazhuang, Hebei Province, because Hebei Province itself is an industrial province, and Shijiazhuang is the capital of this province, so the air pollution will be more serious.

Beijing, of course. Beijing is the political, economic and cultural center of our country, so it is inevitable that there will be many enterprises and a lot of vehicle exhaust emissions.

It's Tianjin, and the smog in this place is very serious, and there is a long time every year, and the air environment is very bad.

Web link: Smog days are inevitable, so come to a good bottle of air inhalation.

Beijing Beijing ......

Smog is probably not a new word, and there is such a bad component in the air we live in that threatens our health. 6 cities are completely free of smog, why are these 6 cities completely free of haze? 6 cities are completely free of smog, is there a city that accompanies you?

Six cities are completely smog-free.

According to the 2015 monitoring of the new air quality standards carried out in 338 cities above the prefecture level across the country, the results show that the proportion of air quality compliance days in 338 cities is between, with an average of ; The proportion of days with average excess is as follows: the proportion of days with light pollution, moderate pollution, severe pollution and severe pollution. Among these cities, only six cities, Malkang, Lijiang, Shangri-La, Tacheng, Ali and Nyingchi, achieved 100% of the air quality compliance days last year.

Without exception, none of these six cities belong to the country's first- or second-tier cities, not even third-tier cities, but it is precisely because of this that these places have good air quality.

Why are these 6 cities completely free of smog?

Ma Jun, director of the Beijing Institute of Public and Environmental Affairs, told the "Daily Economic News" reporter that these areas are basically vast and sparsely populated, without a large number of industrial emissions, and the characteristics of many industries are more prominent.

Take Malkang, for example, which means in Tibetan"Where the flames are strong", by extension"A thriving place"。Malkang is located on the southern edge of the Qinghai-Tibet Plateau and the northwest of the Sichuan Basin, with an area of 6,633 square kilometers and a permanent population of about 60,000 people.

Almost the same size, an area of 6,597 square kilometers of Nanjing, with a population of more than 8 million people, in addition to being a key city of national scenic tourism, Nanjing has many titles, including: is an important comprehensive industrial production base in the country, has formed electronic information, petrochemical, automobile manufacturing, steel as the pillar, with software and service outsourcing, smart grid, wind power photovoltaic socks, rail transit and other emerging industries as the support, advanced manufacturing and modern services coordinated development of the industrial pattern.

In 2015, Nanjing's annual average was 57 micrograms per cubic meter, exceeding the standard.

The reasons for the rapid dissipation of urban smog are as follows:

1.High urban temperatures: Urban temperatures are relatively high, and water molecules in the air are easy to evaporate, which reduces the moisture content in the air and makes the haze disperse faster.

2.High wind speed in cities: Cities have a higher density of buildings and relatively high wind speeds, which can carry away pollutants in the air, making the haze disperse faster.

3.Low air humidity in cities: The air humidity in the first city of the city is relatively low, and the content of water molecules is low, which makes the haze disperse faster.

4.More rainfall in cities: Relatively high rainfall in cities can wash away pollutants in the air, making the haze disperse faster.

In summary, the main reasons for the rapid dissipation of urban haze are high urban temperature, high wind speed, low air humidity and high rainfall.
