Car pollution and health

Car pollution and health

air purifier,car air purifier

With the increasing number of civilian vehicles, cars have gradually become one of the main living spaces for car owners. Compared with the importance of automobile exhaust pollution, the pollution inside the car is often ignored. This article briefly describes the pollution inside a home car.

Where does the pollution inside the car come from?

In general, there are three main sources of pollution in domestic cars:
First, interior parts such as artificial leather and textiles in the car, such as carpets, roof felts and cushions, contain a lot of harmful substances such as formaldehyde, benzene and xylene. The indoor air monitoring center of the Interior Decoration Association has tested 200 vehicles. According to the indoor air quality standards, it is found that nearly 90% of the cars have air formaldehyde or benzene content exceeding the standard, and most of the vehicles have five times the formaldehyde standard. Above, the air quality in the new car is the worst.

Second, if the car air conditioner evaporator does not carry out cleaning and care for a long time, it will produce harmful substances such as amines and bacteria, resulting in poor air quality or even lack of oxygen in the car. The smell of carbon monoxide and gasoline produced by automobile engines will also degrade the air quality inside the car.

Third, the gas exhaled by the human body and the smell and dander generated by the body, accumulated in the closed car, can not be emitted or removed, and the air quality inside the car will also be degraded.

What is the danger of pollution inside the car?

The study found that after the new car leaves the factory, the concentration of harmful gases in the car is high and the volatilization time can last for more than 6 months. During this period, some drivers who drive will feel unwell and even cause a car accident. It is also reported that there are a large number of bacteria and harmful substances such as amines and nicotine in the car, which may cause dizziness, nausea, sneezing and other symptoms, and even cause diseases; especially when the windows are closed and the fresh air volume is insufficient. Drivers may experience dizziness, drowsiness, coughing, etc. when driving, or make them feel depressed and irritated, unable to concentrate, not only endangering the health of drivers and passengers, but also endangering the safety of passers-by.

How to prevent and control pollution inside the car?

The prevention and control of pollution inside the car must start from the following aspects:
First of all, it is necessary to verify whether the decorative materials such as plastic parts, roof felts, seats and floor mats installed by automobile manufacturers meet environmental protection standards;

Secondly, don’t arbitrarily decorate the car, and you can’t introduce pollution sources such as inferior car accessories into the car in order to get the “gift decoration” and other benefits;

In addition, the easiest and most effective way is to open the window and keep the inside of the car ventilated; regularly clean the interior of the car and pay attention to the interior trim of the car.

Tip: Today, most air conditioning ventilation systems in the car are equipped with air filters only at the air inlets and outlets for simple primary filtration. Therefore, in order to maintain the cleanliness in the cabin, the owner can be in the cabin. Add an air purifier.
As people spend more and more time in the car, in order to avoid the pollution inside and outside the car, it is hoped that you will pay attention to and pay attention to improving the environment inside the car, enjoying both comfort and health.

In recent years, relevant data shows that the smell inside the car has become the most headache for the owner. Especially in the case of exposure or suffocation, the enclosed interior environment will cause some unqualified interiors, cushions and other items to release excessive formaldehyde and other gases, especially the problem.

Some owners have reported that the smell inside the car is unpleasant, and some car owners have experienced many uncomfortable symptoms. Light eyes dry, dizziness, itchy throat, severe even suffering from allergic rhinitis, bronchitis, throat cysts.

We subconsciously always overlook an important place, the air inside the car.

The main reason is that the car has been in a fully enclosed state for a long time. On the one hand, the air is not circulated, and on the other hand, the air-conditioned room that is sealed for a long time is also a safe haven for harmful bacteria. Long-term in such a car environment, physical health is difficult to be guaranteed.

Always pay attention to the health problems brought by the car environment, pay special attention to the crowd: pregnant women, children and frail elderly. Pregnant women are exposed to harmful air pollution for a long time, which may easily lead to the possibility of deformity in children, and for children, it may seriously damage their intellectual development. The body of the old man is in a downturn, and the tiny involvement can easily lead him to a critical spiral.

The concentration of eight volatile organic compounds benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde and acrolein commonly found in the car. Among them, formaldehyde, acetaldehyde and acrolein are typical irritants, and there must be an irritating reaction to the respiratory tract. If the concentration of formaldehyde is too high, it will shed tears. Benzene is a trigenic substance that is carcinogenic, teratogenic, and mutagenic.

Tips:In the narrow space of the car, unqualified leather, interior accessories, floor mats, perfumes, explosion-proof membranes, and sound-insulating cotton that are not easily found may be sources of pollution.
In order to better protect the health of family members, air purifiers have become the best choice for people. Air purifiers are no longer unfamiliar to most people, but do you know about air purifiers? In the face of the market’s dazzling array of air purifier products, how to choose a cost-effective and suitable for yourself?

Ordinary car air purifiers use a filter to filter out large particles of contaminants, and then use a blower to blow out the filtered air. But this passive purification, the effect is not as good as we think. Compared with ordinary air purifiers, K05 uses HEPA high-efficiency filtration to absorb harmful substances (TVOC) and fine particles (pm2.5) that are invisible to the naked eye, releasing negative ions, and then bid farewell to the odor inside the car.

How much do you know about the harm of PM2.5 to the human body?

How much do you know about the harm of PM2.5 to the human body?

air purifier

Although PM2.5 is only a component of the Earth’s atmospheric composition, it has an important influence on air quality and visibility. Compared with coarser atmospheric particles, fine particles have a small particle size, are rich in toxic and harmful substances, have a long residence time in the atmosphere, and have a long transport distance, thus having a greater impact on human health and the quality of the atmospheric environment. Studies have shown that the smaller the particles, the greater the harm to human health. Fine particles can drift farther away, so the range of influence is larger.

Fine particulate matter is more harmful to human health because the smaller the diameter, the deeper the area into the respiratory tract. Particles of 10 μm diameter are usually deposited in the upper respiratory tract, and below 2 μm can penetrate deep into the bronchioles and alveoli. After the fine particles enter the human body to the alveoli, it directly affects the ventilation function of the lungs, making the body easily in anoxic state.

There is already a large body of epidemiological evidence that PM2.5 has both acute and chronic health effects. The acute health effect is reflected in the high PM2.5 exposure to increase the risk of acute respiratory diseases and cardiovascular and cerebrovascular diseases. Chronic toxicity is reflected in PM2.5 may induce lung cancer, COPD (chronic obstructive pneumonia), cardiovascular and cerebrovascular diseases and other chronic diseases. Studies have also shown that exposure to fine particles can affect the human immune system, nervous system, and the like.

About 2.1 million people die every year from the increase in particulate matter such as PM2.5

The Chinese Academy of Sciences has identified six sources of PM2.5 in Beijing. It is reported that the 2012 Global Environment Outlook 5 published by the United Nations Environment Program pointed out that 700,000 people die each year from respiratory diseases caused by ozone, and nearly 2 million are premature. Deaths are related to particulate matter contamination. The Proceedings of the National Academy of Sciences (PNAS) also published a research report saying that the average life expectancy of humans has been shortened by five and a half years because of air pollution.

There is scientific evidence that in the negative ion environment, human blood will greatly increase the absorption of sodium, potassium and calcium. Thereby improving the acid-base balance of the human blood system and helping the body to transform into a weakly alkaline constitution.

The water of the main component of our body is also called human body fluid. Except for stomach acid, most other body fluids are weakly alkaline, and its PH value is 7-8. This PH value of body fluid is the most beneficial to the survival of our body’s cells, which is conducive to the coordinated operation of various tissues and organs, so that they can perform their duties and exert their maximum effect, making people healthy, energetic, and not easy to get sick. Even if they get sick easily Healed; on the contrary, people’s body fluids become sour, which is not conducive to health.

The OLANSI KJ200G-A3 series air purifier has multiple filters to remove PM2.5 and release negative ions.

5 big coups to deal with indoor PM2.5

5 big coups to deal with indoor PM2.5

air purifier

Nowadays, many people are terrified when they hear “PM2.5”. If they want to escape the claws outside, they can wear professional masks. If they are indoors? No need to worry, this is a coup!

How to measure indoor air quality?

There are two main methods for indoor air quality testing, one is to use portable testing instruments, and the other is to sample the air quality and return to the laboratory for analysis.

There are many environmental testing companies in the market. If you want to know the air quality in your home, you can ask these agencies to come to your door.

What is the indoor PM2.5 standard?

There is no national standard for indoor PM2.5 monitoring, which is usually in accordance with the standard of outdoor air quality, that is, less than 75 μg/m3, which is generally harmless to the body.

Five great tricks to learn!
■ In an office environment, try to keep the printer and copier away from people.
■ When cooking at home, turn on the hood and close the kitchen door. After the dish is cooked, continue to use the hood for a few minutes.
■ It is best not to smoke indoors.
■ Put some plants indoors, which also have a purifying effect on air quality, such as green radish, aloe vera, and spider plant.
■ When the outdoor PM2.5 reaches the level of moderate pollution (150 μg/m3), the use of an air purifier can improve the indoor air quality.

Why is the indoor PM2.5 larger than the outdoor?

Why is the indoor PM2.5 larger than the outdoor?

air purifier

Why is the indoor PM2.5 concentration greater than outdoor?
This is because, as we usually say, PM10 refers to the concentration of fine dust particles of 10 microns; PM2.5 refers to the concentration of fine dust particles of 2.5 microns, and such small particles in the room are suspended particles. Every day, we open the window to ventilate. Under the horizontal action, the larger the diameter, the greater the force in the horizontal direction, and the moving speed is faster than the small diameter. Thus, the larger particles can be quickly removed from the outside. The small diameter will remain indoors. On the other hand, the particles of human nighttime metabolites are mostly less than 0.3 microns, which are not easy to diffuse, and will accumulate more indoors. After a long time, there will be a situation where the indoor inverse ratio is higher than the outdoor PM2.5 concentration. In the case of raging fog, everyone is hard to be alone, and the way to shut down the door, regardless of the window, is self-deception.

What should I do for the health of my family and children?
1. Persevere in mopping the floor and keep it three times a day
Practice has proved that mopping the floor can increase the relative humidity of the air, and at the same time, the negative ions neutralize the precipitated particles to form larger particles to settle on the ground. If not treated in time, under the movement of the air, it must be lifted again and must be as soon as possible. Removed.
2. Install an air purifier
Our air purifiers have multiple filters to remove PM2.5.

Prevention method

1.Filtration
Including air conditioners, humidifiers, air fresheners, etc., the advantage is that the concentration of PM2.5 is significantly reduced, the disadvantage is that the filter needs to be cleaned or replaced.

2. Water adsorption method
Ultrasonic atomizers, indoor water curtains, pools, fish tanks, etc., can absorb hydrophilic PM2.5 in the air. The disadvantage is that the humidity is increased and the hydrophobic PM2.5 cannot be effectively removed.

3. Plant absorption method
Plant leaves have a large surface area, can absorb harmful gases and adsorb PM2.5. The advantage is that they can produce favorable gas. The disadvantage is that the absorption efficiency is low, and some plants produce harmful gases.

Life response
1. The smog weather is less open, it is best not to go out or morning exercise
The haze weather does not advocate opening the window in the morning and evening. It is best to wait for the moon to come out and then open the window for ventilation. Haze weather is a “dangerous day” for patients with cardiovascular diseases, especially those with respiratory diseases and cardiovascular diseases. It is best not to go out in the fog, and it is not suitable for morning exercise. Otherwise, it can induce illness and even heart attack, causing life-threatening. . Experts pointed out that the reason why foggy days is a “dangerous day” for patients with cardiovascular disease is because the air pressure is high during fogging, and the oxygen content in the air is increased. People can easily feel chest tightness, and the morning is humid and cold. It can cause cold irritation, which can easily lead to esophageal fistula, blood pressure fluctuations, and increased heart load. At the same time, some pathogens in the fog can cause headaches and even induce diseases such as high blood pressure and cerebral hemorrhage. Therefore, people with cardiovascular diseases, especially those who are old and infirm, should not go out in the foggy days, and should not practice in the foggy morning to avoid danger.

2. Wear a professional dust mask
Generally, conventional masks do not work. Because the particles are too small, KN90, KN95, and N95 dust masks can effectively filter such fine particles, and at the same time, choose a mask that suits you to avoid leakage and cause leakage. In addition, face and bare skin should be cleaned immediately after returning home. Better anti-PM2.5 masks are mainly filters rather than masks. For example, masks with activated carbon filters and medical masks are not protected against PM2.5.

3. Drink more tea, such as Tongjiu tea, Tongshen tea, Tongjiu granules, and platycodon grandiflorum.
Tongli stem tea has the function of clearing the dust and filtering the lung dust, which can strengthen the ability of alveolar cells to discharge toxic fine particles, and can help the body to excrete PM2.5 particles and other harmful substances accumulated in the body.

4. A small amount of vitamin D supplement
In winter, there are many fogs and less sunshine. Because there are too few ultraviolet rays, the production of vitamin D in the human body is insufficient. Some people may also suffer from mental depression and depression, and may supplement some vitamin D if necessary.

5. Eat light and drink honey water
For a foggy diet, choose a light, digestible food that is rich in vitamins. Drink plenty of water and eat more fresh vegetables and fruits. This will not only supplement various vitamins and inorganic salts, but also moisturize the lungs, remove dryness, and relieve cough. The role of spleen and kidney. Eat less irritating foods and eat more pears, clams, oranges, oranges and other foods.

6. Deep cleaning
The skin on the surface of the human body is in direct contact with the outside air and is easily damaged by haze. Especially in the bustling city of the smog and smog, in addition to the fog and endangered “muscle” at any time, due to construction, automobile tail gas, industrial fuel burning, fireworks and fireworks, etc. It is inevitable that it will block the formation of blackheads in the pores, causing skin problems such as pore blockage, keratin accumulation, and skin peeling. Therefore, the first measure of self-protection is to deeply clean the surface of the skin and clean the pores.

7. Minimize smoking or even not smoking
There is a large amount of PM2.5 in the smoke, which has direct and indirect harm to the human body. If you can’t stop people around you from smoking, you should try to stay away from the smoke.

The Proceedings of the National Academy of Sciences (PNAS) also published a research report saying that the average life expectancy of humans has been shortened by five and a half years because of air pollution.

London poison fog incident
The toxic fog on December 5, 1952 was one of the most painful moments in London’s history. The poisonous fog caused at least 4,000 deaths. Countless Londoners had difficulty breathing, traffic was rampant for many days, and millions of people were affected.

World Health Organization first identified PM2.5 carcinogenic
On October 17, 2013, the World Health Organization’s International Agency for Research on Cancer issued a report that first identified air pollution as a cause of cancer in humans and regarded it as a universal and major environmental carcinogen. However, although air pollution has been proposed as a holistic carcinogen, its damage to the human body may be the result of the simultaneous action of several major contaminants it contains.

Injury organ
Long-term exposure to particles can cause cardiovascular and respiratory diseases as well as lung cancer. When the concentration of PM2.5 in the air is higher than 10μg/m3 for a long time, it will bring about an increase in the risk of death. For every 10 μg/m3 increase in concentration, the total risk of death increased by 4%, the risk of death from cardiopulmonary disease increased by 6%, and the risk of death from lung cancer increased by 8%. In addition, PM2.5 is highly resistant to organic pollutants such as polycyclic aromatic hydrocarbons and heavy metals, which significantly increase the risk of carcinogenic, teratogenic and mutagenic.

Impact climate
It is generally believed that PM2.5 is only air pollution. In fact, the impact of PM2.5 on the overall climate may be even worse. PM2.5 can affect cloud formation and rainfall processes, indirectly affecting climate change. In addition to salt in seawater, fine particulate matter PM2.5 is also an important source of condensation in the atmosphere. Under some conditions, there are too many PM2.5s, which may “divide” water, so that the clouds in the sky will grow little, and the blue sky and white clouds will become less than before. Under some conditions, PM2.5 will increase the condensation of condensed nodules. The number of raindrops in the sky increases, and extreme rains may occur.

Fine particles are also called fine particles, fine particles, PM2.5. Fine particulate matter refers to particulate matter with an aerodynamic equivalent diameter of 2.5 microns or less in ambient air. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small component of the Earth’s atmospheric composition, it has an important impact on air quality and visibility. Compared with coarser atmospheric particles, PM2.5 has small particle size, large area, strong activity, easy to attach toxic and harmful substances (for example, heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transport distance. Therefore, the impact on human health and the quality of the atmospheric environment is greater.
In February 2013, the National Science and Technology Terminology Committee named the Chinese name of PM2.5 as fine particles. The chemical composition of the fine particles mainly includes organic carbon (OC), elemental carbon (EC), nitrate, sulfate, ammonium salt, sodium salt (Na+) and the like.

Air pollution leads to obesity? Air purifiers are an effective way to solve indoor pollution

air purifier

Maybe we don’t care about air quality in our daily life, but you don’t know that air pollution can lead to obesity. Drinking water will make the fat star feel deeply malicious… A study published in the Journal of the American Association of Experimental Biology, pointed out that air pollution can lead to obesity and disturb the body’s metabolic capacity. Suddenly want to sing a song: Breathing is the pain of getting fat?

The researchers placed pregnant mice and their offspring in two rooms. One group breathed contaminated air, and the other group used a filter to purify the air polluted by the particles and then fed them with the same food. The results showed that the mice that breathe air polluted had more weight gain, had severe inflammatory reactions in the lungs, and had higher total cholesterol than the control group. Similar problems occurred in the offspring of the mice. After eight weeks of birth, the mice in the contaminated group were heavier than the other group. According to article author Junfeng Zhang, air pollution is an important behavior and biological factor leading to obesity.

Behaviorally speaking, when air pollution is serious, people are not willing to exercise. From a biological point of view, pollutants can upset the body’s metabolic capacity. Polluted particles enter the lungs, stimulating inflammation in the lungs, which in turn induces a series of inflammatory responses. When adipose tissue shows a higher level of inflammation, more fat is deposited in the tissue, increasing body weight. This is an excuse for obesity: it is the fault of air pollution!

We know that the main cause of obesity is eating too much and exercising too little. Exercise is an effective way to lose weight, but if you exercise in polluted air, it is harmful to your health. When air pollution becomes a cause of obesity, why not contain it in the cradle? Not only do you get fat, there are many hazards from air pollution, and diseases such as respiratory diseases and eye and nose irritation are more common.

Air pollution in life can be seen everywhere: smoking, driving, cooking, spraying… The polluted air contains a variety of tiny particles, which have very little gravity and can stay in the air for a long time, we are unknowingly They are inevitably inhaled. Therefore, indoor pollution problems need to be resolved. At present, air purifiers are a more effective way to solve indoor pollution.

New research shows that the more serious the air pollution, the worse the student’s test scores

air purifier

According to foreign media reports, a new study conducted by British scientists recently showed that students exposed to high air pollution may lead to worse test scores. Air pollution has long been associated with harmful side effects, leading to respiratory problems, heart and liver dysfunction, fatigue, headaches and reduced life expectancy. Now, a new study suggests that this effect will expand further and may have a negative impact on brain activity.

Researchers at the London School of Economics and Political Science performed statistics on the results of more than 2,400 students taking the test and compared the air pollution levels in the test rooms. As a result, students’ test scores may drop by 3.4% in a highly polluted environment where PM10 exceeds 75 micrograms per cubic meter.

The project also conducted another study based on 400,000 exams for Israeli youth. The researchers found that the PM2.5 concentration in the examination room was equal to or higher than 23.5 micrograms per cubic meter, which may result in a 3% drop in test scores.
Researchers suggest that students should be exposed to extreme air pollution in the days when they have exams.
