Is Ashes caused by PM2.5?

Although the particles in the air are invisible to the naked eye, the particles can reduce the visibility of the air, make the blue sky disappear, and the sky becomes a gray one. This weather is gray sky. In ash days, the concentration of PM2.5 is significantly higher than usual, and the higher the concentration of PM2.5, the lower the visibility .

Although different sizes of particles in the air can reduce visibility, the finer PM2.5 is more capable of reducing visibility than coarse particles. The reduction in visibility is essentially a hindrance to the transmission of visible light. When the diameter of the particles is close to the wavelength of visible light, the particles have the strongest ability to scatter light. The wavelength of visible light is between 0.4 and 0.7 microns, and particles with particle sizes near this size are the main components of PM2.5. The theoretical calculations also clearly show this: the extinction coefficient of coarse particles is about 0.6 m2/g, while the extinction coefficient of PM2.5 is much larger, between 1.25-10 m 2 /g, of which PM2. The extinction coefficients of ammonium sulfate, ammonium nitrate and organic particles, which are the main components of 5, are all about 3, which is five times that of coarse particles. Therefore, PM2.5 is the main reason for the reduced visibility of ash day.

It is worth mentioning that the ash day is caused by particulate matter pollution, while the foggy weather is a natural weather phenomenon, and there is no necessary connection with man-made pollution. The main difference between the two is air humidity, which is usually called fog when the humidity is greater than 90%, and sputum when the humidity is less than 80%, and a mixture of smog when the humidity is between 80-90%.

Nowadays, many people talk about PM2.5 color change, why? Because the air quality is getting worse, the mask has become a must-have item. What’s worse, the air problem has also extended into the home, so the purifier has almost become a necessity, and the air purifiers on the market have sprung up. How do we compare Olansi’s K15A air purifier?

Exterior

With a simple and stylish appearance, the white color is suitable for any position in the home. The design of the straight barrel style has four universal wheels at the bottom, which is very convenient to move, compared to those of the fixed type. For the device, it is much more flexible. The top has a large air outlet, and the purified air is discharged from the top. Similarly, the large area means that the air volume (fresh air) will increase.

At the bottom of the K15A, there are four universal wheels, which are much more flexible than the fixed purifier. Which room needs to purify the air, push it directly there, and don’t worry about the children at home, because K15A With the child lock and pressing the two buttons of wind speed and mode, the child lock mode will be activated. At this time, even if the child (including the adult) clicks, no operation can be performed. In addition, if the top cover of the K15A is turned on after power-on, the machine will automatically power off to prevent some safety hazards. After all, these years have also seen many tragedies caused by leakage of such household appliances. And after removing the cover, take it directly to the faucet and rinse it. It is very convenient to clean. Look inside, there is a layer of net fixed below, it can also play a role in preventing children from reaching out and moving.

According to a Science Daily report, according to a recent study by the Columbia Children’s Environmental Health Center at Columbia University’s School of Public Health and Postage, parents exposed to polycyclic aromatic hydrocarbons (PAH), one of the components of air pollution, can cause children to At the age of 9, there is an increased probability of behavioral problems associated with attention deficit hyperactivity disorder (ADHS).

Mothers exposed to high levels of polycyclic aromatic hydrocarbons during pregnancy show five times higher than average

Researchers tracked 233 non-smoking pregnant women and their children in New York City, USA, for a period of time from maternal pregnancy to child growth to childhood. The results showed that children exposed to high levels of polycyclic aromatic hydrocarbons during pregnancy showed a higher than average number and extent of typical ADHD symptoms compared with children who did not receive high levels of polycyclic aromatic hydrocarbons during pregnancy. The probability is five times higher. This study was the first to explore the association between parental exposure to PAH and ADHD in school-age children.

“This study suggests that exposure to higher levels of PAH in New York City may play a role in children with ADHD.” Research chief, Frederica Perrela, Director of the Columbia Children’s Environmental Health Center (Frederica) Perera) said this. “These findings are worrying because attention issues can affect children’s school performance, social relationships, and workplace performance.”

The Centers for Disease Control predicts that approximately 10% of American children between the ages of 4 and 17 have one of the following three types of ADHD: attention deficit ADHD, which means that children are difficult to concentrate, distracting and confused; Hyperactivity and impulsive ADHD; or both. As for what is causing ADHD, it is still unclear. At present, scientists only know or suspect that genes and environmental factors may have a certain impact.

PAH is a toxic air pollutant that has many sources, such as transportation, residential boilers, and power plants that use fossil fuels. The researchers measured the mother’s PAH exposure using the PAH-DNA adduct in the mother’s blood during the delivery of the mother. The level of PAH exposure in children is measured by the PAH metabolite in the urine of children at the age of three or five. The ADHD behavioral problem is assessed using the Connor Parent Rating Scale.

Due to the emergence of new technologies such as networks, computers, and smart phones, people now spend more time indoors, so a good indoor environment is becoming more and more important for us to stay healthy. If there is a problem with the air that breathes all the time, it can’t be ignored. So, do you know what kind of situation indicates that indoor air has been contaminated?

For this problem, the World Health Organization gave us the answer and released the physical symptoms caused by indoor environmental pollution, mainly in the following eight aspects:

(1) The eyes, especially the cornea, nasal mucosa and laryngeal mucosa have irritation;

(2) Drying of mucous membranes such as lips;

(3) The skin often has erythema, urticaria, eczema, etc.;

(4) It is easy to fatigue;

(5) It is easy to cause headaches and symptoms of respiratory infections;

(6) often have a feeling of chest tightness and suffocation;

(7) Frequent allergies of unknown cause;

(8) Frequent feelings of dizziness, nausea, vomiting, etc.

If your body has the above symptoms, you need to check the indoor environment and purify the indoor air.

There are many indoor pollutants, mainly three types.

First, formaldehyde, adhesives, artificial building materials, etc. will emit a large amount of formaldehyde, formaldehyde has a great effect on the endometrium, throat and skin;

The second is benzene series, which are widely present in various organic solvents for building decoration materials, such as various paints and coating additives, thinners and some waterproof materials. Long-term exposure to low concentrations of benzene can cause dizziness, insomnia, listlessness, memory loss and other neurasthenia;

The third is TVOC, which is the abbreviation for total volatile organic compounds in the room. Mainly from paints, water-based paints, adhesives, cosmetics, detergents, wood-based panels, wallpapers, carpets, etc. If the concentration of TVOC is too high, it will directly stimulate the body’s sense of smell and other organs, causing irritative allergic reactions and neurological effects.

So how do we prevent indoor air pollution? The current purification methods are mainly divided into the following

  1. Activated carbon adsorption method

Activated carbon has a large surface area and is capable of adsorbing a certain amount of harmful gases on the surface. Activated carbon will fail after adsorption and is suitable for solving low-concentration pollution. It is rarely used in indoor pollution control.

  1. Chemical deodorant method

The effect is not long-lasting, and it has certain toxic side effects, which easily cause secondary pollution.

  1. Natural ventilation method

By opening the window and opening the door, the indoor air naturally flows, and the purpose of purifying the indoor air has been achieved. However, this method is only used to remove indoor odor, can not completely eradicate indoor pollution, and often has haze outside.

  1. Professional product management uses an air purifier. Efficient air purifier can quickly and effectively purify the air in a single room, absorb dust mites, inhibit the spread of pathogens, and remove formaldehyde, benzene and TVOC.
