Does PM2 5 kill people???

Not in the short term, but because of its pollution of the lungs, it will cause respiratory, cardiovascular, ** and other diseases. I also checked, to prevent injuries, you need to "internal conditioning and external defense", external defense is to get a gas mask (if you dare) to wear, internal conditioning is to eat more fruits and health products that nourish the lungs, drink more water and take some Chinese patent medicine to nourish the lungs and moisten the lungs, recommend Pan Gaoshou, I have already bought it, I have bought the honey refining Chuanbei loquat paste and the Chuanbei loquat dew, and I have already used it. In short, it is internal conditioning and external defense.

I don't think so...Otherwise, I wouldn't have died long ago after 20 years in Beijing...However, it is getting more and more serious now, if you don't pay attention to personal protection, it is estimated that you will die! I advise you to pay more attention to it, after all, it is very important to moisten the lungs, drink some honey refining Sichuan shellfish loquat paste from Pan Gaoshou, which clears the lungs and moisturizes the lungs, and also helps to eliminate the fine particles in the body.

No way?! I often have to go out for work, and I don't want to die! In other words, I also use the Pan Gaoshou honey refining Sichuan shellfish loquat paste that a few netizens upstairs said, after all, it is a time-honored brand, and it is also safe to use.

The volume is not large, it is convenient to drink a sip at work every day, and I also asked my mother to prepare a Sydney pear for me to eat every day. I don't want to die...

Pay attention to the hygiene of the respiratory tract, wear a mask when you go out, clean your mouth and nose when you arrive at work or home, and pay attention to personal hygiene. Wash your hands frequently. The diet should be light and nutritious.

Fine particulate matter is also known as fine particles, fine particles, .

Although fine particulate matter is only a small component of the Earth's atmosphere, it has important implications for air quality and visibility, among other things. Compared with coarser atmospheric particulate matter, fine particulate matter has a smaller particle size, is rich in a large number of toxic and harmful substances, and has a long residence time in the atmosphere and a long transportation distance, so it has a greater impact on human health and atmospheric environmental quality.

Fine particulate matter is more harmful to human health because the smaller the diameter, the deeper it enters the respiratory tract. Particulate matter with a diameter of 10 m is usually deposited in the upper respiratory tract, and particles below 2 m can penetrate deep into the bronchioles and alveoli. After fine particulate matter enters the alveoli of the human body, it directly affects the ventilation function of the lungs, making the body easy to be in a state of hypoxia.

Long-term exposure to particles can lead to cardiovascular and respiratory diseases, as well as lung cancer. When concentrations in the air are higher than 10 g m for a long time, the risk of death increases. In addition, it is easy to adsorb organic pollutants such as polycyclic aromatic hydrocarbons and heavy metals, which significantly increases the probability of carcinogenicity, teratogenicity and mutagenicity.

1. Cause airway obstruction or inflammation.

Studying reality, and below the particles, 75 deposited inside the alveoli, we can imagine that the eye gets sand into it, and the eye becomes inflamed. The depths of the respiratory system are also a sensitive environment, and fine particulate matter stays in the respiratory system for a long time as foreign bodies, which can also cause inflammation of the respiratory system.

2. Pathogenic microorganisms, chemical pollutants, oil smoke and other "hitchhiking" enter the body to cause cancer.

In addition to doing bad things on their own, they are also like cars that can freely enter the respiratory system, and other healing substances such as bacteria and viruses "hitchhike" into the depths of the respiratory system and cause infection.

Epidemiological investigations have found that polycyclic aromatic hydrocarbons in urban atmospheric particulate matter are associated with the incidence and mortality of lung cancer in residents. In the process of polycyclic aromatic hydrocarbons entering the human body, fine particulate matter plays a role as a free ride, and most of the polycyclic aromatic hydrocarbons are adsorbed on the surface of the particulate matter, especially on the particulate matter with a diameter of less than 5 mm, and there are very few polycyclic aromatic hydrocarbons on the large particulate matter.

That is, the more in the air, the more opportunities we have to come into contact with the carcinogens polycyclic aromatic hydrocarbons.

3. Defects caused by affecting fetal development.

A survey from northern Bohemia conducted a study of pregnant women exposed to high concentrations and found that high concentrations of fine particulate pollutants may affect fetal development. Concentrations of atmospheric particulate matter are associated with increased mortality in preterm infants, neonatal mortality, low birth weight, intrauterine growth retardation, and congenital defects.

4. Particulate matter can enter the blood vessels through the exchange of qi and blood.

In a 2009 experiment, human alveolar epithelial cell lines were used as models in the atmosphere of Beijing to study the toxicological effects. In this experiment, a comparison of different exposure conditions, such as 200 micrograms, was found to cause inflammatory damage to these cells as the concentration of the virus increased.

hazards.

1. Lead to heart disease and arteriosclerosis.

As a tiny particulate matter, it is very easy to cause cardiovascular disease. Research data shows that the more hazy weather, the higher the incidence of heart disease.

hazards. 2. Cause lung cancer or lung sclerosis.

As particulate matter entering the lungs, it is also the first to bear the brunt of the harm to the lungs. Even knowing what it means, most people ignore the little killer. These particles penetrate the nasal cilia in the nasal cavity and enter the lungs, where they precipitate and accumulate, causing lung sclerosis and even lung cancer.

hazards. 3. Cause asthma or chronic bronchitis.

With the increase of ultrafine particles and nanoparticles, some small germs enter the respiratory tract through the nasal cilia by hitchhiking, and then cause respiratory diseases such as asthma. This is also the reason why the foggy weather, asthma attacks.

hazards. Fourth, affect fetal development.

The data showed that the higher the PM10 concentration, the higher the incidence of respiratory illness in children and their parents, and the impact was particularly significant.

What exactly are the hazards? Can smog cause acute myocardial infarction? Is this true?

Meteorologists and medical experts believe that haze caused by fine particulate matter is even more harmful to human health than sandstorms. Particulate matter with a particle size of more than 10 microns will be blocked out of the human nose; Particulate matter with a particle size between microns and 10 microns can enter the upper respiratory tract, but some of them can be excreted through sputum, etc., and will also be blocked by the villi inside the nasal cavity, which is relatively less harmful to human health; Fine particles with a particle size of less than microns, the diameter of which is equivalent to 1 10 of the size of a human hair, are not easy to block. When inhaled, it can directly enter the bronchial tubes, interfering with the gas exchange in the lungs, causing diseases such as asthma, bronchitis and cardiovascular disease.

Each person inhales an average of about 10,000 liters of air per day, and the fine dust that enters the alveoli can be quickly absorbed and directly enter the blood circulation and distribute to the whole body without liver detoxification. Second, it impairs the ability of hemoglobin to deliver oxygen, resulting in loss of blood. For patients with anemia and circulatory disorders, there can be serious consequences. For example, it can aggravate respiratory diseases and even cause heart diseases such as congestive heart failure and coronary arteries.

In short, these particles can also enter the blood through the bronchi and alveoli, and the harmful gases and heavy metals in them are dissolved in the blood, which is more harmful to human health. The physiological structure of the human body determines that there is no ability to filter or block, but the harm to human health has gradually exposed its terrifying side with the progress of medical technology.

In the European Union, it leads to a decrease in the average life expectancy of people. It can also be a vector for viruses and bacteria, contributing to the spread of respiratory infections. At present, major developed countries in the world, as well as Japan, Thailand, and India in Asia, will be included in the air quality standards.

Wei Fusheng, an academician of the Chinese Academy of Engineering and former chief engineer of the China Environmental Monitoring Station, also showed that the higher the PM10 concentration, the higher the incidence of respiratory diseases in children and their parents, and the impact was particularly significant.

Although people's awareness of environmental protection has increased in recent years, and the quality of the environment has been improved, smog still often occurs in many first- and second-tier cities, and ultra-high concentrations occur from time to time. If you have children at home, and you can't move to a living environment with the best air for the time being, then you should understand some of the content summarized by Löfmeier, and actively improve the indoor air environment, which is very beneficial to the growth of children.

Effects of smog on children:

1. Respiratory tract infections and lung cancer;

2. Emotional instability;

3. Influence of ocular function;

4. Rickets in children;

5. Affect intellectual development.

How to reduce the harm of smog to children?

1. Install an air purifier or fresh fan to improve the air condition at home and purify the air.

2. If you want to take your child out, you should bring a mask for your child.

3. In hazy weather, there are a lot of harmful substances that will adhere to the baby's face, and the child should be washed after coming back.

4. Take your child to the hospital for physical examination regularly, and if there is a problem, it should be detected as soon as possible.

Loefmeier focuses on the research, production and sales of optical particulate matter sensor technology. The dust laser sensor LD16 is a high-precision particulate matter concentration sensor based on laser Mie MIE scattering theory, which can be embedded in various instruments or environmental improvement equipment related to the concentration of suspended particulate matter in the air to provide timely and accurate concentration data. It is suitable for air purifiers, air conditioners with purification function, range hoods, smoke alarms, fresh air systems, etc., to help improve the indoor air environment.

Harm to the human body is a long-term process, and its effects are not something that can manifest itself in a day or two or months. Inhalers may develop the disease after more than 10 or 20 years of continuous inhalation. Professor Wang Zhen of the Department of Respiratory and Critical Care Medicine of Beijing Chaoyang Hospital Affiliated to Capital Medical University revealed that the impact on the respiratory system is the most direct.

Every winter haze day, the number of outpatient visits to the hospital's respiratory department increases significantly. On the contrary, after a heavy snowfall, not only did the number of cold patients in the hospital decrease, but many patients with respiratory diseases also suffered varying degrees of relief. This is because snow filters inhalable particles and purifies the air, so people usually find the air especially fresh after snow.

In addition, harmful particles containing heavy metals and various pathogenic bacteria can penetrate into the bloodstream through the body's circulatory system, causing damage to organs including the heart and blood vessels.

What's in the air? How much does it affect people's health?

Dr Wong Chi-ming, Associate Professor at the School of Public Health, Li Ka Shing Faculty of Medicine, The University of Hong Kong, led a research team to conduct the first study in Asia on the effects of long-term exposure to human health. Using statistical modelling and adjusting for individual and regional confounders, the research team found that every 10 units (measured in micrograms per cubic metre) increase in concentrations was associated with a 14% increase in natural deaths, a 22% increase in deaths from cardiovascular and circulatory diseases, a 42% increase in deaths from ischemic heart disease, and a 24% increase in deaths from cerebrovascular stroke.

In addition to increasing the risk of cardiovascular and cerebrovascular diseases, it can also cause respiratory diseases, which can interfere with the gas exchange in the lungs when entering the bronchial tubes, causing diseases including asthma, bronchitis and cardiovascular diseases.

According to the indoor pollution research report released by Tsinghua University, the amount of indoor inhalation is four times that of the outdoors, and people stay indoors for 80% of the time, so it is very necessary to purify indoor air. Ecological anion technology with anion system and pollutant collection systemThe generated eco-grade negative ions can effectively remove the air, and it has been found that the negative ions can combine with the particulate matter pollutants in the air, condense into a clump, and settle to the ground to achieve the purpose of purifying the air.

Dr. Asanobu Maki of Toho Medical University of Japan, and Dr. Masayoshi Nakagawa of Nihon University of Japan released research results confirming that eco-grade negative ions are the best way to cope with indoor environments. In the air containing high concentrations of small particle size negative ions, the most harmful dust, bacteria, viruses, etc. with a diameter of less than 1 micron are almost zero.
