Ms. Li's home inexplicably appeared in the case of excessive formaldehyde, originally the family did not think about this aspect, but the symptoms of the child and formaldehyde poisoning are too similar, and then the family found experts to test, sure enough, the test equipment explained that the formaldehyde content in the house exceeded the standardEven more than 03ppm！As we all know, 01ppm of formaldehyde may cause irritation and food poisoning
Therefore, the results confirmed that the old house where I lived for 8 years once again exceeded the formaldehyde standard, what happened?
In fact, there are two main reasons:
1. The volatilization time of formaldehyde
According to the statistics of relevant surveysThe formaldehyde in the house can be retained for 3 to 15 yearsEven investigators have detected some formaldehyde substances in 15-year-old houses.
Therefore, the cleaning of formaldehyde can not be solved by simply opening windows for ventilation, even if the decoration is completed and the house has lived for 8 years, the hidden danger of formaldehyde concentration cannot be ignored.
2. For the sake of decoration materials
A large number of wood boards, dyes, fabrics, etc. are used for decoration, and the accumulated formaldehyde concentration is very highIn addition, the retention capacity of formaldehyde is too strong, and the retention time is too long, furniture, dyes, carpets, etc., will continue to release formaldehyde, even after 8 years, the concentration of formaldehyde will not be significantly reduced, and it is still within the dangerous range.
Formaldehyde was classified as a Class I carcinogen by the World Health Organization's International Agency for Research on Cancer in the early years. Popularity: Long-term exposure to excessive formaldehyde will cause respiratory diseases such as tearing eyes, conjunctival congestion and inflammation, allergies, nasopharyngeal discomfort, cough, acute and chronic bronchitis.
It has toxic effects on the cardiovascular system, endocrine system, digestive system, reproductive system, and kidneys.
In severe cases, it may also induce leukemia, especially myeloid leukemia. In particular, children, pregnant women, and the elderly are the main victims of formaldehyde.
Not necessarily.
Many people think that the old house has been old enough for a long time, and even if there is formaldehyde, it should have volatilized early, but in fact, it is not. Toxic and harmful gases such as formaldehyde in synthetic sheetsSustainable release, some up to 3 years or more.
In general, in a long-term environment, the formaldehyde content should not exceed 003 ppm, and some experts have tested an old house, formaldehyde as high as 022 ppm due to the use of inferior finishing materials and the lack of ventilation in the room. After testing, ventilation is the most effective way to remove formaldehyde, but if the decoration materials are not good, even if it is dried for several months or years, it may still exceed the standard!
Many people are racking their brains in order to avoid the problem of formaldehyde when decorating, and when choosing a board, they must choose a board with higher environmental protection indicators, so are these standards really reliable?
First of all, I must tell you that the mandatory standard for formaldehyde emissions from wood-based panels in my country still follows GB1 85 80 -2017 issued many years ago"Formaldehyde Release Limit in Interior Decoration Materials, Wood-based Panels and Their Products".
Among them,The standard is only available at the highest level of E1 and specifies the method of determination with a limit value of 0124mg/m3。
This standard is the basis for the board, which means that it must at least comply with E1.
So, what are the standards for E0 and F4? In fact, E0 comes from "GB T 181 02 impregnated paper laminated wood flooring", "GB T 58 49-200 6 blockboard", "GB T 984 plywood", these three standards stipulate that the formaldehyde emission of E0 should be 05mg/l。
The F4 standard, on the other hand, is the Japanese standard, which is stipulated by the JAS standard of the Japanese Ministry of Agriculture, Forestry and Fisheries, and the requirement must reach 03mg/l。
Some merchants say, my plate meets these standards, you can buy it with confidence! In fact, there is a sentence that I believe everyone has heard, called "Talking about toxicity regardless of dosage is a hooligan", and this sentence is not wrong with this.
Whether it is E1, E0 or F4 plates, the most important thing is to look at the dosage.
For example, if you have a room in your home with wooden floors, custom wardrobes, board tables, chairs, and beds, although the release of a single product is up to standard, it may be superimposed on the formaldehyde emission level.
Therefore, even if all the boards in your home meet the standards, you must control the amount used.
Because formaldehyde is a first-class carcinogen, there is no safe measurement of formaldehyde. Living in an environment with formaldehyde for a long time may also cause lesions due to excessive cumulative inhalation.
Therefore, don't have survivorship bias, and don't think that your household plate is good and there is no formaldehyde.
The harm of formaldehyde is so great, the decorator will tell you the truth: these 4 things in the home are the source of formaldehyde, you must be careful
1. Glass glue
Glass glue is needed in many places such as countertop seams, toilet fixing, window fixing, etcOne of the main components in glass glue is formaldehyde.
Therefore, the formaldehyde content in the glass glue is relatively high, and the regular brand products must be selected when purchasing, and the aldehyde removal should be paid attention to in time after use, and the glass glue should be discarded as soon as possible after use.
2. Textiles
Many people will not understand it when they see it, formaldehyde will also appear in textiles? The premise here is that brightly colored textiles, such as the red and purple curtains at home, the red quilt covers and bed sheets on the bed, all of which contain more formaldehyde.
We see some brightly colored textiles around us, almost all of which are made of dye, so they contain a lot of formaldehyde, and the darker the color, the greater the formaldehyde concentrationTherefore, when choosing curtain covers, bed sheets, and leather sofas, try to choose plain colors and less formaldehyde.
3. Poor quality wallpapers
Many people will think that the wallpaper on their walls is not only cheaper than tiles, but also can be changed at will. But you have to understand that if you accidentally choose cheap and low-quality wallpaper, then the danger is great.
Although many wallpaper processes are constantly improving and improving, inferior wallpaper still exists. When inferior wallpaper is glued, the harmful substances produced are not only formaldehyde, but also benzene.
As the temperature rises, these fused gases are emitted in the home and inhaled into the body.
4. Mattresses
Palm mattresses are also an important source of formaldehyde release.
The reason is that a large amount of formaldehyde-containing glue is added to these mats for shaping, and these mats are simple and low in cost due to their simple processWidely present in the market
There is an easy way to discern it, which is to break the mat by hand, ifIt is very hard and has glue residue, it can basically be judged that it is a glue mat, and you should be careful when encountering this kind of mat.
1. Pregnant women
Studies have shown that exposure to high levels of formaldehyde during pregnancy can cause spontaneous abortion of embryos and increase the incidence of low birth weight infants. In particular, the risk of exposure is highest during the first 3 months of pregnancy, which can affect embryonic development throughout pregnancy.
2. The elderly
As we age, our body functions are gradually weakening, and if we are stimulated by external pollutants at this time, it is easy to produce some bad symptoms. Formaldehyde is not only not a strong irritation, but also has a certain toxicity, which is obvious, which will make the aging body worse, and in serious cases, it will even be life-threatening.
3. Office personnel
The office is a relatively closed environment, the lack of air circulation leads to low indoor oxygen content, coupled with work, it is easy to lead to the reduction of the metabolic ability of the body and brain of office workers, and working in an environment with poor air quality for a long time is very detrimental to physical health.
In many office areas, the height of personnel, desks, and office chairs is dense, which makes the total amount of pollutants increase sharply, and it is easy to exceed the standard, forming the pollution of the office environment.
4. Infants and young children
This is the group most vulnerable to formaldehyde!
Compared with adults, if living in the same environment, children are more likely to get sick or be attacked by pollutants, and children's respiratory system has not yet formed a complete self-protection, so the respiratory system is relatively weak, so if formaldehyde exceeds the standard, the first victim is children.
For infants and toddlersAbout 80% of the day is spent indoors.
For children, the annual winter and summer vacations are the peak period of formaldehyde release, if the indoor formaldehyde exceeds the standard, it will seriously affect the development of infants and children, and even induce various diseases.
1. Sexual disease at home
When a family lives in an environment with serious formaldehyde pollution, it will be harmed by formaldehydeAs a result, uncomfortable symptoms may occur at the same time. Therefore, as long as you pay more attention after moving in, even if the formaldehyde exceeds the standard again, it can be found and treated in time.
2. Discomfort in the throat and nose
Experts advise that formaldehyde is a colorless, odorless and strongly irritating gas. Therefore, when we breathe, it will directly irritate the mucous membranes of our throat and nose, and then there will be cold-like reactions such as sneezing and coughing.
3. Inexplicable cold and fever
Generally, we have a cold and fever because of a cold, but did you know that formaldehyde poisoning also has a cold and fever?
If we wake up in the morning and often feel dizzy and dizzy, as well as the symptoms of cold and fever, then we can consider whether it is excessive formaldehyde.
4. Itching and rash
If you find that you or your family members keep getting red bumps and itching after living in a new house for a period of time, it may be caused by excessive formaldehyde. Because ** is the first medium of contact with the air, and it is also the most honest "body guard".
I believe that those who have babies at home are more worried about whether the formaldehyde at home exceeds the standard, so they will take certain methods to remove formaldehyde!
Use greenery to remove formaldehyde
When I moved to a new house, my husband bought nearly 30 pots of pothos and put them at home, and I felt like I was in a forest park during that time. But there are studies that show that green plants are good for formaldehydeThere is no adsorption effect, but formaldehyde will harm green plants.
2. Fruit peel and tea
Putting fruit peels, tea, etc. at home to remove formaldehyde, is the practice of Mom's generation to remove formaldehyde, in fact, everyone misunderstands this method of removing odors, and putting fruit peels at home can cover up the odor of interior decoration through the peculiar smell emitted by the pineapple peel or grapefruit peel itself.
For example, a newly bought refrigerator can remove odors by putting fruit peels, but it is not possible to use fruit peels to remove formaldehyde.
This method can only mask the odor, but it has no effect on removing formaldehyde, and it will paralyze our response to harmful gases, but it will be more harmful to our health.
According to the survey, 80% of people feel that simple ventilation can effectively reduce formaldehyde concentration, and even the vast majority of people think that opening windows for a few hours a day is enough.
But is that really the case? Let's talk about experiments!
The relevant experiments are as follows: firstly, the formaldehyde release source is enclosed in the experimental cabin, and the formaldehyde concentration in the experimental cabin is kept at 0 after stabilization2mg m3 and maintain the temperature at 25 degrees.
Then open the two ends of the experimental cabin and place it in an outdoor environment to achieve "north-south ventilation".
After a period of time after the data were obtained, the experimental chamber was sealed again to observe the change of formaldehyde concentration.
After many tests, a general conclusion has been reached: in some cases, the formaldehyde concentration can be reduced to the national standard of 0 after about 10 minutes of ventilationBelow 1mg m3, if the decoration in the home is complex and the ventilation is not smooth, the time will be longer.
After closing the doors and windows, the original formaldehyde concentration will be reached again in about 30 minutes.
Even if we use long-term ventilation to remove formaldehyde, this is still not enough
For the sake of our own health and that of our families, we must not ignore formaldehydeIf you want to remove formaldehyde safely and efficiently, in addition to daily ventilation, it is best to match a professional player!
It is recommended that you choose such a fast and visual formaldehyde removal jelly, and I will introduce it to you below!
This formaldehyde jelly, it canActively grabs the formaldehyde free in the air and converts formaldehyde into water and carbon dioxide, which is simple and efficient to remove aldehyde.
The key point is active decomposition, not adsorption.
Like the bamboo charcoal, orange peel, and tea that we use in the tradition, we basically wait for the prey to come to the door, that is, which formaldehyde factor is floating in the air, and it will be caught if it is more unlucky, so the efficiency and effect will be much lower.
Many families still use the dirt method!
What's more, bamboo charcoal, which has no ability to decompose after adsorption, will release formaldehyde after absorbing formaldehyde! In fact, only by turning formaldehyde into harmless carbon dioxide and water and irreversible can the effect of real formaldehyde removal be achieved.
Don't look at it as just a tiny canIt only took 3 minutes to "see" the process of removing formaldehyde:
The initial formaldehyde concentration in a confined space is 014mg per cubic meter, while the sanitary standard for formaldehyde in the room air is specified as 008mg per cubic meter.
This value has exceeded the standard, but it is a common value in many families, which is what we call formaldehyde has been continuously released. Then, we put the formaldehyde jelly in it, and after 3 minutes, we magically found that the formaldehyde concentration dropped to 0014mg per cubic meter, not only within a safe range, but also removes 90% of formaldehyde.
First of all, from a security perspective:Because most of them are used at home, safety must be in place.
As a constituent party, the first step is to look at its foundation, that is, the cost list.
This formaldehyde jelly is a plant-based formula that can be directly contacted, non-toxic and non-irritating, even if the child accidentally touches it.
After all, it is to solve the formaldehyde poison gas, and the safety of the product itself is the foundation, otherwise it will be too painful to slap the face.
Secondly, in terms of efficiency:
Unlike other similar products that cannot get a real report on the effect of removing aldehyde, this formaldehyde jelly has the test reports of many institutions such as Tsinghua University Building Environment Monitoring Center, Micro Measurement, and Nano Laboratory, which proves its "ability" again and again.
According to the report of the Building Environment Testing Center of Tsinghua University, within 24 hours, the formaldehyde removal rate of formaldehyde jelly is 957%。
That's at least a full 1% higher than similar products!
Don't underestimate only 1%, in your own home, 1 more point of security, is 10 more points of security. If you take the college entrance examination, you can kill thousands of people by raising one point!
Each bottle of formaldehyde jelly comes with oneActivatorsDrip it into the jar before use and the product will be activated.
jelly releasedPlant-derived aldehyde removal ingredients, will be with the indoor air flow, contact with formaldehyde and other harmful moleculesFirmly adsorb and decompose them.
After activation2-3 hours, you can clearly see the formaldehyde net magic boxBegin to change colorFinish.
Formaldehyde net magic box of aldehyde removal components, passedIt reacts with formaldehyde uninterruptedly, decomposing while looking for it, leaving no chance for formaldehyde to "resurge".Secondary pollution will not exist!
After 12 hours, basically two-thirds of the color had turned yellow.
Within 48 hours, it turns milky white and begins to enter the "stable work period".
A week later, you'll seeThe dark blue color gradually turns pale yellow until it turns white "freeze-dried".The volume inside has also been reduced.
When it's completely shriveled up to the size of a coin, it's a reminder that you need to replace it in time.
Some friends may ask, how much can such a small box manage?
The results of the test report show that in the area with less pollution, one can cover about 14 square meters, and the larger the place, the more serious the pollution, the appropriate amount of more cans should be added. I have come to buy everything, and don't be stingy in terms of quantityIt's a matter of personal safety(It's not that the family doesn't have this condition).
Recommended at homeEvery room, in the car, at the deskAnd there's thatBathroomThe air circulation is inherently poor, and it is more likely to grow bacteria and mildew, and emit peculiar smells, so put them in a can.
Early detection, early replacement,Visual aldehyde removal jelly makes people breathe with a special sense of security!
Whether you buy or rent the house you live in now, whether you have just moved or lived in it for more than ten years, the latent power of formaldehyde is unimaginable! Now hire a professional aldehyde removal team, one time is thousands, sometimes one is not enough, several times.
Finally, I would like to remind you again:The formaldehyde problem has never been alarmist.
Especially now, in cars and rooms, formaldehyde will only become more and more active. Putting it in the home and car not only removes formaldehyde and ensures indoor air quality, but also reduces various odors.
