The air quality in the living environment is poor. Will you get sick if you live for a long time?

The air quality in the living environment is poor. Will you get sick if you stay for a long time? The air quality level and its impact on human health are as follows:

First class, the air quality evaluation is excellent, and it has no impact on human health;

Grade II, with good air quality evaluation and no obvious impact on human health;

Grade 3, mild pollution, healthy people have * * * symptoms;

Grade 4, moderate pollution, common symptoms in healthy people.

Grade 5, serious pollution, serious symptoms of healthy people.

Experts say that air pollution is the enemy of human health, and air quality directly affects people's work and life. Poor air quality will distract people's attention, reduce work efficiency, and even cause symptoms such as headache, nausea, fatigue and redness of the skin, which is collectively called "sick building syndrome". People are eager to improve the increasingly bad living room and office environment and improve the quality of life.

The air quality in Tangshan is poor because there are many heavy industries, so the air quality is poor, but Tangshan is improving ~

Guangzhou Environmental Air Quality Monitoring (1) The cause of acid rain is due to the extensive use of fossil fuels, and too many oxides of sulfur dioxide and nitrogen in the air are formed with rain. Therefore, the city prone to acid rain is Chongqing. The measures to prevent acid rain are to reduce the use of fossil fuels, or to adopt coal desulfurization technology or develop clean energy instead. (2) the reaction of carbon monoxide and nitric oxide

Why is the air quality in Lanzhou poor? Lanzhou is located in the Yellow River Basin, and is sandwiched by two mountains on the north and south sides. The whole city is a long and narrow terrain. The air doesn't circulate, so the pollutants can't spread. The Yellow River is sandwiched between the north and south mountains to form a typical valley basin, with peculiar terrain and dangerous geographical location, which has become a battleground for military strategists in past dynasties. It is precisely because of this terrain that urban pollution is so serious, which is one of the main reasons. Lanzhou city extends from east to west, with the narrowest part of the north and south only two kilometers, surrounded by mountains, poor air circulation and obvious local microclimate. For example, at the beginning of 2000, cold air moved eastward through Yuzhong and Gaolan in the suburbs of Lanzhou, and it snowed heavily, but there was no snow in the urban area. It can be seen that the air in the urban area does not flow, and Lanzhou has been covered like a quilt, becoming the most polluted-air pollution. Originally, the Yellow River split the two mountains and passed through the city. Lanzhou should be the export of things. But in fact, the Qinghai-Tibet Plateau in the southwest is higher than the sea level, which blocks the movement of the wind, making the gas over Lanzhou unable to flow like stagnant water, and naturally unable to be replaced by new gas, which has become the main cause of pollution.

Followed by climate factors. Lanzhou is located in the western part of the Loess Plateau, with dry climate and scarce precipitation, while the western part is adjacent to the vast Gobi Desert, with poor natural conditions. Dust particles suspended in the air can't be taken away by the wind, but they can't fall to the ground with the wind, so the sight of "yellow sand flying all over the sky" is also a cause of pollution.

However, people should bear the main responsibility for these consequences, and direct pollution is caused by many heavy industrial factories and mines in Lanzhou. After liberation, due to the important geographical position of Lanzhou, the state invested in the construction of a heavy industry base in today's Xigu District in the first five-year plan. The industrial bases based on large enterprises in several countries, such as Lanlian and Lanhua, have played an irreplaceable role in the development of national economy. However, at the beginning, we blindly copied the so-called "Soviet model", lacked scientific theoretical argumentation, and did not investigate and analyze all aspects of Lanzhou. Therefore, heavy industry pollution, that is, the pollution disaster in Lanzhou today, has become more important and become a transportation hub in the northwest with the construction of railway trunk lines such as Longhai, Lan Xin and Baolan. Petroleum refining, chemical industry, machinery manufacturing and wool textile industry have also developed quite rapidly. With the increase of population, the size of the city has also increased. After the reform and opening up, the economy developed quite rapidly, the scale of factories expanded and the old city was rebuilt, especially the proportion of heavy industry was still very large, which made Lanzhou, which was not suitable for being classified as a heavy industry city, become a famous "polluted city". This is a man-made consequence and should be solved by people themselves.

What is the living environment in Jinan? How about air quality and water quality? If you want to choose a better living environment, don't think about Jinan, which is a dirty city in Shandong Province (it should be the dirtiest). Think about how many migrants there are, how much garbage there is, how many small businesses there are, and how much pollution there is. Yantai, Weihai and Qingdao near the sea are all good choices. If you want to be in the inland of Shandong, then Liaocheng, the "Jiangbei Water City", deserves its name! But there are still many business opportunities in Jinan!

Life skills 〡 Poor indoor air quality in winter. Why is the indoor air quality poor in winter?

Due to the low temperature in winter, there is little or no chance to open the window. In dry winter, people are prone to cough and throat problems. People often move, and some homes are carpeted, and the dust on the carpet surface is emitted in the air, so many factors lead to the deterioration of indoor air quality.

What exactly should I do? The analysis is as follows:

1, all kinds of pathogenic bacteria in the air increased.

Winter is a season of frequent respiratory diseases. Because of staying in the office for a long time, all kinds of pathogenic bacteria spread through air and droplets and stay indoors. According to the investigation, some virus and bacteria droplets in the air float for more than 30 hours, which makes people's immunity decline and make them easy to get sick.

2. The pollutants in the air increase.

In addition to the harmful gases such as formaldehyde, ammonia, benzene, radioactive substances and electronic pollution generated by the original office decoration, furniture and computers, it is impossible to open the window for ventilation frequently in cold weather. Many office buildings use central air conditioning for heating, and indoor carbon monoxide, carbon dioxide, floating dust and particulate matter will gradually increase.

There are few opportunities for indoor ventilation.

Resulting in the accumulation of a large number of indoor pollutants.

4. Spend more time in indoor activities.

Because of the cold weather in winter, most people stay in the office for 8 hours a day, and the time for outdoor activities is greatly reduced.

Therefore, the indoor carbon dioxide increases and the oxygen content decreases, causing air pollution and increasing harm to human body.

Some friends who are afraid of cold are even more reluctant to go out for a walk in winter, preferring to stay at home. If you are a homebody, you can try the following methods to improve indoor air quality from your daily life:

1. For rooms without mechanical ventilation, it is recommended to open the window for ventilation at least twice every morning and evening, and the ventilation time should not be less than a quarter of an hour each time;

2. Proper placement of potted plants or plants indoors will help to purify the air and often spray water to improve the indoor air humidity.

3. Buy air purifiers and humidifiers to purify indoor air.

The air quality is poor in autumn. How can we clean the home environment? Poor air circulation leads to poor air: the simplest way is to open the window for ventilation and increase air circulation, which can reduce the content of harmful substances in indoor air, thus reducing the harm of such substances to human body.

The indoor environment causes poor air quality: keep the room clean, reduce the generation of garbage and other wastes, and always keep the kitchen clean, the room clean and the bedding dry; Change regularly, pay attention to the hygiene and cleanliness of pets, and so on.

By installing fresh air system to solve the problem of poor air quality in shopping malls,
