In recent years,The news of formaldehyde causing cancer is not uncommon, and everyone is aware of the importance of removing formaldehyde. Long-term exposure to excessive formaldehyde in the environment will induce bronchial asthma, nausea and headache, and even nasopharyngeal AI and leukemia, especially for children, indoor formaldehyde pollution has become the main cause of high incidence of leukemia in children.
Ms. Chen's family in Nanjing, Jiangsu Province, rented a house through a platform in June last year, and after four months of moving in, Ms. Chen's two-and-a-half-year-old son actually contracted leukemia and died 100 days later.
According to Ms. Chen, the baby's disease is juvenile myelomonocytic leukemia, known as the king of leukemia, transplantation is the only means, unlike other leukemia can be chemotherapy, before the baby has done relevant physical examinations, all the physical examinations show that the baby has no problems. It was only after four months of check-in in November that the baby developed these problems.
This disease is so dangerous that the baby has to draw blood, prick needles almost every day, and often have to do bone punctures. The baby is only over two years old, and he is less than three years old. After the incident, after testing, the formaldehyde in the house they rented exceeded the standard. And the platform recognizes this test report.
According to the survey, at least 2 million children die of formaldehyde poisoning every year in the country. Formaldehyde is a colorless toxic gas, which is listed as a first-class carcinogen by the World Health Organization, and it is recognized as the most "cunning" "killer" in modern society because of its invisible cruel attributes. The most terrifying thing is that this **killer may be lurking around us all the time, endangering our health.
First of all, you must know these two numbers!
0.1mg cubic meter, which is the highest value of the safety standard for formaldehyde concentration in public places in China.
0.08mg cube, which is the highest value of the formaldehyde concentration safety standard in special public places such as homes and kindergartens in China.
Infants and young children due to physical reasons, once the formaldehyde concentration exceeds 006 Cough, asthma and other problems will occur. Many parents think it is a cold symptom, and it does not get better after taking medicine and dripping for a few days! As everyone knows, this is the reason.
According to the statistics of the China Cancer Registration Yearbook, the incidence of leukemia in children aged 0-14 in China is 344 100,000. According to this calculation,Every year, there are about 8,000 new leukemia patients in children aged 0-14 in China
Renovation pollution is the main culprit of childhood leukemia, and surveys have found that 90% of children with leukemia have renovated their homes within six months. Medical studies have proved that indoor formaldehyde pollution has become the main cause of high incidence of leukemia in children.
1. Indoor temperature
Temperature is an important factor affecting the volatilization of formaldehyde, and the boiling point of formaldehyde is -195. It has the characteristics of volatile, and the amount of formaldehyde released rises by about 0 for every 1 rise in indoor temperature15-0.37 times.
If the room temperature is around 22, the indoor formaldehyde emission will be in a critical state. When the room temperature exceeds 28, the indoor formaldehyde emission will increase exponentially.
Therefore, the higher the indoor temperature, the stronger the movement between gas molecules, and the formaldehyde gas in the furniture will be quickly released from the inside of the material into the air.
2. Indoor humidity
The higher the indoor humidity, the faster the formaldehyde is released.
The effect of humidity on formaldehyde is mainly because the urea-formaldehyde glue in the furniture board is produced by the polymerization reaction of urea and formaldehyde, with the increase of humidity, the moisture of the board will increase, and the urea-formaldehyde glue will be decomposed into urea and formaldehyde, thereby increasing the content of free formaldehyde in the air.
Temperature and humidity directly affect the high and low amount of formaldehyde release, because formaldehyde is mainly used in urea-formaldehyde resin adhesive in man-made panels, and the physical and chemical properties of urea-formaldehyde resin are deliquescent and pyrolysis, that is, when urea-formaldehyde resin is exposed to heat (temperature increase) or moisture (humidity increases), formaldehyde molecules will be decomposed in reverse, which is the main reason why formaldehyde release is closely related to temperature and humidity.
3. Superposition effect
The emission source of indoor formaldehyde is not single, it comes from wood-based panels, furniture, mattresses, walls, wooden floors, curtains and various decoration materials, etc., and the indoor formaldehyde concentration is the cumulative sum of various emission sources.
The evaporation time varies according to the classification of different release sources.
Relevant studies have shown that walls (except wallpaper) and curtains have a large contact area with air, so the formaldehyde release rate is faster, while plywood (multi-layer board), fiberboard (MDF), particleboard (particle board) and blockboard (large core board) are affected by the finishing material and edge banding process, and the formaldehyde release time ranges from 3 to 15 years.
Affected by the carrying capacity of indoor space, the more complex the interior decoration, the greater the formaldehyde release!
I can often see that everyone has some experience in cleaning in the background, and they will leave a message to recommend some useful products, such as the magic wipe, but they are immediately reminded: there is formaldehyde, don't use it!
Because it has been exposedFormaldehyde contentIf the standard is exceeded, there will be residue after several washes.
Combined with the scenarios that everyone uses, it is very risky.
Hand holding wipe something:Formaldehyde direct contact**;
Put it at home:The formaldehyde released may be inhaled by babies and adults;
Used to wash dishes:There will be formaldehyde residues on the tableware, and there is a risk of ingestion.
This looks very dangerous, see what the experts say!
Experts have something to sayThere are many aliases for the Magic Rub: Kling Rub, Magic Sponge, Magic Nano Rub, Nano Sponge Rub, and so on.
But the material is melamine resin foam, also called melamine-formaldehyde resin foamA polymer obtained by the reaction of "melamine" and "formaldehyde".
It sounds scary, but when manufacturing, the production standards are strictly followed, and the product will not exceed the formaldehyde standard.
The reality is,Most consumers have no way of knowing how it is produced, so it is advisable to buy with caution
In this way, it seems that it is not only a small magic wipe, but also some kitchen cleaning products that we actually find difficult to ensure its quality, so we do it dailyHow to buy effective and safe kitchen cleaning productsThis?
After referring to the recommendations of the Provincial Quality Supervision Bureau and consulting experts, we have compiled 4 suggestions:
1.Look at the packaging. Choose the logo pattern with clear handwriting and complete label information. (There is a production license, product standard number, manufacturer name, address, net content, production batch number or production date and shelf life or expiration date, instructions for use, etc.).
2.Try to buy in large shopping malls, supermarkets, and formal e-commerce channels. (The quality of well-known brand products is relatively stable and reliable, and the performance is good).
3.Try to choose some natural extracts, do not contain phosphorus and organic volatiles, and at the same time pH neutral products, so that the damage to the environment and ** is smaller, and the damage caused by formaldehyde can be reduced. (Generally, there will be a claim on the product packaging).
4.Pay attention to the scope of application of the product and choose the appropriate washing product. (Generally, the product packaging will indicate whether it is suitable for ceramics, plastics, wood, metal and other materials).
Many people think that formaldehyde is far away from us, but in fact, environmental experts as insiders pointed out: a few inconspicuous things in the house are formaldehyde households, and you must be careful when buying and using.
1. MDF wardrobe
When you buy a wardrobe, you need to look at the material of the wardrobe, which is used by many wardrobes on the market at this stageHigh-density fiberboard to replace solid wood panels,**It is also relatively cost-effective, and many people choose!
But thisHigh-density fiberboard contains a lot of formaldehydeIt is worth mentioningFormaldehyde in this type of high-density fiberboard cannot be removed quicklyIt is also possible that it will remain in the product for a long time, which will be beneficial to human healthCause a lot of damage!
2. Inferior mattresses
We all have mattresses in our bedrooms, but did you know that this kind of thing tends to be processed and manufacturedFormaldehyde-containing additives are added to ensure toughness, enhance hardness and so on.
Especially that kindBrown mattressesSome black-hearted manufacturers even do not hesitate to add a large amount of glue to ensure hardness, or be cautious.
3. Coatings
In the decoration process, the largest formaldehyde is the wall coating, often we use several kinds of paint in a wall, brushed layer after layer, so the wall has become the place with the highest formaldehyde content at home.
4. Soft package and hard package
Now decoration is very popular to do soft and hard bags, mainly for TV background wall, sofa background wall, bedside background wall, bedside and other positions.
This design, due to the soft texture of the materials used and the soft colors, can soften the entire space and create a warm and soft atmosphere.
Regardless of whether a soft or hard package is used, the base material is the MDF used, which is often referred to as MDF, and then the sponge and leather are selected as needed, so that the finished product can be made.
Once this material is run to the home renovation, it will become formaldehyde".release source", because MDF is meant to belongMost of the cheap materials are not environmentally friendly, and as long as they are used, formaldehyde will inevitably exceed the standard.
This is also why many people's bedside at home always has a smell, but it has not faded for three or five years, which is because of the use of inferior MDF in the later stage, which has become a source of formaldehyde release, which affects human health.
If you have these kinds of things at home, it is recommended that you replace them as soon as possible, or remove formaldehyde as soon as possible, because these items may release toxic gas for "15 years".
In recent years, there have been many life-threatening cases of formaldehyde disease.
There are survey data showing that:
Caused by indoor air pollution every yearThe death toll has reached 1110,000, an average of about 304 deaths per day.
1. Short-term exposure to excessive concentrations of formaldehyde
If more sensitive people come into contact with formaldehyde, their eyes will be irritated and watery, and their throat will be hoarse and sore and their respiratory tract will also be damaged.
2. Long-term exposure to excessive formaldehyde
Long-term exposure can cause more severe symptoms. Mild symptoms willHeadaches, insomnia, loss of appetiteIt may also cause sensory disturbances or depression.
At a deep level, it can reduce immunity and respiratory function, even rightGenes produce adverse effects.
The environment with excessive formaldehyde will have a greater impact on pregnant women and children, and there is a probability that it will cause fetal malformations or even miscarriage.
Men who have been exposed to it for a long time are also at risk of developing problems with decreased sperm motility. Long-term exposure to excessive environments will increase the probability of developing malignant diseases such as leukemia, lymphoma, and myeloid leukemia.
The hazards of formaldehyde can be described as"Every aspect".Let's be on guard!
With the improvement of modern living standards, people pay more and more attention to the quality of the home environment. However, there is one potential threat that many people overlook after renovating a new home or buying new furniture: formaldehyde. What are the symptoms of long-term exposure to formaldehyde?
Symptom 1: DizzinessFormaldehyde is an irritating gas that is exposed to high concentrations of formaldehyde for a long timePeople often experience symptoms such as dizziness, headache, drowsiness, etc. This is because formaldehyde can directly stimulate the central nervous system, adversely affect the nerves, and affect the normal function of the brain.
In addition, long-term dizziness may also cause problems such as difficulty concentrating and memory loss, which can seriously interfere with daily life and work.
Symptom 2: Eye stinging
Another common formaldehyde hazard is stinging eyes and tears. When formaldehyde concentrations are high, people tend to experience burning, dryness, and even redness and tearing in their eyes.
This discomfort makes it difficult to concentrate and increases the difficulty of work and life. Long-term exposure to formaldehyde may cause eye diseases and further harm eye health.
Symptom 3: Allergies
In addition to affecting the respiratory system and eyes, formaldehyde can also adversely affect **. Long-term exposure to high concentrations of formaldehyde, people often experience symptoms such as allergies, itching, and erythema.
Some people may even experience severe allergic reactions, such as rashes, blisters, etc. It's not just a ** problem,It can also seriously interfere with the quality of daily life, causing physical discomfort and pain.
In the above cases, whether it is formaldehyde poisoning or not, it should beTake your child to the hospital for a check-up in time, nothing but peace of mind, if there is anything you can also be in time, don't take it seriously!
Removing formaldehyde is a scienceThere are a lot of doorways, but there are too many misunderstandings, and the following methods are trueCan it remove aldehydes?
1. How many basins of water can remove formaldehyde?
Formaldehyde is easily soluble in water, which is no problem, and it is theoretically possible to remove formaldehyde through tap water.
But in real life, formaldehyde will generally fill the whole house, and if it is only a few basins of water, the contact area between water and air is very small, and it is impossible to adsorb much formaldehyde.
And the formaldehyde release period is inAfter actually moving into a new house or moving into an office, it is impossible to put a lot of basins of water on the ground every day.
Therefore, removing aldehydes with water does not have a great effect.
2. Remove formaldehyde from wet towels?
Because formaldehyde can be dissolved in water, many people think of soaking the towel and then using a wet towel to wipe the indoor table, wardrobe and other formaldehyde release sources. However, it should be noted that the amount of water in the wet towel is actually small, and the time it stays on the surface of the formaldehyde release source is not very long, and it does not play any role in removing aldehyde.
3. Can the peel remove formaldehyde?
Pineapple peel removes formaldehyde odor, this method is popular with many old people. I hope that in the future, all friends will not use it again after the decoration of the new house. The fruit skin does not remove formaldehyde pollution, but uses its own fragrance to cover up the odor of formaldehyde, and the pollutants are not reduced at all.
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
Therefore, mentionWake up: ventilation is not the most effective means!
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.
