In recent years, more and more news has been reported again and againFormaldehyde poisoningThe incident calls for and reminds everyone to do a good job in formaldehyde treatment measures, but there will still be many families who do not pay enough attention to it, and formaldehyde poisoning will occur, causing some tragedies.
Ms. Li's family inexplicably had excessive formaldehyde, and the family did not think about it, but the symptoms of the child were orFormaldehyde poisoningIt's too similar, and then the family found an expert to test it, and 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
So, it turned out to be an old house that I lived in for 8 years, againFormaldehyde exceededup,What the hell is going on?
According to the 2020 National Home Environmental Protection Report, 31 of the 67,624 households surveyed3% of households exceed formaldehydeThe formaldehyde excess rate is still higher than 15% within 5 years after the completion of the room decoration.
Even if many families carefully select decoration materials, sometimes they will inevitably "fall into the pit".
The indoor pollution caused by home renovation is very seriousUnqualified decoration materials will emit a variety of harmful substances, including formaldehyde, benzene, ammonia, radon, volatile organic compounds (TVOC), etc. And the most common of them is excessive formaldehyde.
In a sense, true zero formaldehyde is nothing short of a fantasyThe difficulty of being free of formaldehydes in the world is equivalent to that there are no thieves in the world, and we do our best to minimize the harm value and reduce it to the range that the human body can bear.
Formaldehyde, also known as antaldehyde, is a colorless, irritating and water-soluble gas, which has the effect of coagulating proteins, and its 35% 40% aqueous solution usually becomes a solution that is often used as an impregnated specimen.
Formaldehyde is a substance with high Du properties, and formaldehyde is high on the priority control list of toxic chemicals in China2nd place.
There are two standards for the standard value of indoor formaldehyde content stipulated by the state:
The first isThe detection requires closure for 12 hours, and the indoor formaldehyde concentration is not higher than 01mg/m³。Referring to the World Health Organization's limit standard for indoor formaldehyde concentration, it is the minimum standard for human settlements and human health.
The second is:It is required to be closed for 1 hour, and the indoor formaldehyde concentration is not higher than 008mg/m³It is applicable to the mandatory control specifications of environmental pollutants before the delivery of construction projects.
So when the formaldehyde concentration in the room exceeds 01 is a situation that exceeds the standard and is abnormal。Formaldehyde is a class of carcinogens recognized by the World Health Organization, when the indoor formaldehyde is seriously exceeded, it will increase the risk of cancer in the human body, so when the new home is renovated, do not rush to move in.
Hazard 1: Induce blood diseases in childrenMedical studies have proved that excessive indoor formaldehyde has become the main cause of leukemia. According to clinical data, 90% of children with leukemia have recently renovated their homes, and all of them have varying degrees of formaldehyde exceedance! This is enough to show that there is an inevitable connection between formaldehyde and leukemia.
Hazard 2: Increase the incidence of asthma in childrenThe World Health Organization announced that 100,000 people worldwide die of asthma every year due to formaldehyde pollution in indoor air, and 35% of them are children. Among them, the prevalence rate of children aged 1-5 years is as high as 85%! Formaldehyde has become a major cause of asthma in children.
Hazard 3: Affect children's intellectual developmentAccording to a study in 2001, a study in the United Kingdom showed that formaldehyde can cause a greatly reduced mental health in children. This phenomenon occurs even before birth, which means that formaldehyde can also affect the development of the fetal brain in the placenta.
The number of deaths caused by indoor air pollution in the country has reached 11 per year10,000, an average of about 304 deaths per day. Most of them are caused by decoration pollution, and just looking at the data can scare you into a cold sweat.
It's not about creating panic, it's about prompting you:Formaldehyde is really a "god of death" that will take away life
In our long lives, about 80% of the time is spent indoors, so the quality of indoor air quality directly determines our physical health. Among the many pollutants, formaldehyde is particularly harmful to our health. Because formaldehyde is not only a class of carcinogenic and teratogenic substances, but also one of the causes of childhood leukemia.
Among the many groups that harm formaldehyde, children are often the most harmed. This is because children spend a little more time indoors each day than adultsAnd the main respiratory zone of children happens to be the deposition zone of formaldehyde in the air。That is, children breathe more formaldehyde than adults.
In addition, we all know that long-term exposure to excessive formaldehyde will destroy our body's immune system, thus making us extremely susceptible to illness. However, children's immune systems are not yet fully developed, and once they are damaged by formaldehyde, they will naturally become more susceptible to illness.
According to epidemiological statistics, there are about 40,000 new leukemia patients in China every year, 50% of whom are children.
1. The molecular weight of formaldehyde is larger than the average amount of air, so formaldehyde is mainly concentrated in the space range of 1 meter on the ground, which happens to be the main respiratory zone of infants and young children;
Second, when quiet, the air inhalation of infants and young children is twice that of **, so infants and young children inhale much more formaldehyde than **;
3. Infants and young children have immature physical function development and low resistance, so they are most likely to become the target of formaldehyde.
Every year, there are many examples of formaldehyde poisoning in children due to decoration pollutionThis is because there are many similarities between the early symptoms of formaldehyde poisoning in children and the symptoms of flu, which leads some parents to ignore their children's condition, causing irreparable tragedy.
The number of deaths caused by indoor air pollution in the country has reached 11 per year10,000, an average of about 304 deaths per day.
Most of them are caused by decoration pollution, and just looking at the data can scare you into a cold sweat.
It's not about creating panic, it's about prompting you:Formaldehyde is really a "god of death" that will take away life
1. Formaldehyde pollution greatly increases the risk of leukemia in children
Children have become a high incidence of leukemia, in addition to the internal cause of children's weak immune function, formaldehyde emitted by interior decoration materials is one of the "killers".
According to relevant statistics, 90% of children with leukemia are related to decoration pollution, and excessive formaldehyde can lead to blood diseases in children, which is seriously manifested as leukemia.
2. Harm to the respiratory system
When we smell irritating formaldehyde, the respiratory system has inhaled them into our body at the same time, and the respiratory system is irritated by the undesirable stimulus.
Experiments have long proved that long-term inhalation of a small amount of formaldehyde can cause adverse reactions such as water and eye stinging, and cause bronchial asthma and other diseases. Overdose may directly cause breathing difficulties and even death.
1: Family members have uncomfortable symptoms such as uncomfortable throat and uncomfortable eyes.
Formaldehyde is a strong irritant, and it will directly irritate the mucous membranes of the respiratory tract such as the throat and nose, as well as the conjunctiva of the eyes, and it is easy to feel uncomfortable.
2: Family members are prone to dizziness and nausea, especially in the morning; Weakened immunity.
People have different perceptions of formaldehyde irritation, but once they live in an environment where formaldehyde exceeds the standard for a long time, they will have symptoms such as dizziness, decreased immunity, and susceptibility to colds.
3: The green plants raised at home are inexplicably diseased, yellow, wilted, and even died.
Plants will also absorb formaldehyde through respiration, and once the plant cannot degrade formaldehyde in time, formaldehyde will poison the plant, causing the plant to turn yellow and wilt, and the lesion to die.
Myth 1: Soil tricks:
(1) Green plants:Many people place green plants in their homes to remove formaldehyde, the most common of which is pothos. In fact, green plants do not have the ability to absorb formaldehyde. Although plants such as tiger pill orchid and drug sucker grass have some formaldehyde absorption effect, the effect is minimal.
(2) Onion and grapefruit peel:Many people will also put some fruits or vegetables with a special smell, such as onions, grapefruits, etc., but these fruits and vegetables have no scientific basis in addition to formaldehyde, but can only mask the smell of formaldehyde in the house, so don't do useless work.
Myth 2: Professional formaldehyde removal
That is, some of the ones on the marketThe so-called professional formaldehyde removal companyThey use a variety of methods to get rid of it.
But in essence, these so-called professional formaldehyde removal,Most of them are "IQ taxes", and if you say it directly, it is foolish.
They used some chemical materials to spray on the newly renovated new home to seal it, so that the formaldehyde could not disperse the smell temporarily, so as to achieve the so-called removal of formaldehyde.
After half a month, or even a month or two, after these chemical materials have passed their expiration date, formaldehyde will be emitted again. And the chemical materials they use are themselves harmful to the body.
Myth 3: Air conditioning fresh air or fresh air system
Whatever it isAir conditioning with fresh airStillFresh air systemThe function of both is the same, both are used to keep the indoor air fresh.
Therefore, many people say that when the air flows, it can naturally reduce the formaldehyde content, which also achieves the purpose of reducing formaldehyde.
But in fact, this method can only be used with a slight effectIt can't really be cleared.
As we all know, after the end of the decoration, it is necessary to ventilate for 3-6 months before moving in, the purpose is to remove formaldehyde, and compared with grapefruit peel, onion, green plants and other methods of removing formaldehyde, ventilation is still more reliable.
The main indoor pollutants are home decoration and furniture, most of which are hidden in the depths and continuously released from the inside to the outside through daily volatilization, and the release time can be as long as 3-15 years.
To put it simply, as long as there is a source of indoor pollutants, pollutants will continue to be generated, and what can be done by opening windows for ventilation is only to replace the free pollutants in the air and the pollutants adsorbed on the surface of objects through air flow, treating the symptoms but not the root cause.
Opening windows for ventilation is the simplest, most convenient and most economical way to remove formaldehyde, but it is not the most effective way to remove formaldehyde.
Opening windows for ventilation to remove formaldehyde is not something that can be done simply by opening windows for ventilation, but it is necessary to choose a scientific ventilation method based on the characteristics of formaldehyde and the surrounding environment.
In addition, the frequent real cases in recent years have verified that this statement is not easy to come by.
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 China still follows GB18580-2017 issued many years ago"Formaldehyde Emission 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 18102 impregnated paper laminated wood flooring", "GB T 5849-2006 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 a Japanese standard, which is stipulated by the JAS standard of the Ministry of Agriculture, Forestry and Fisheries of Japan, 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.
It is understood that most people do not have a clear concept of repeated exceedances of formaldehyde, and even say that they do not know about it! Therefore, most people's formaldehyde poisoning occurs unknowingly.
As the temperature rises, the release rate of formaldehyde will also be higher and higher, if you do not do a good job of removing formaldehyde in summer, wait until the formaldehyde release peak,Formaldehyde can cause great harm to the body
As an insider, environmental experts pointed out that several inconspicuous daily necessities at home are large formaldehyde, and you must be careful when buying and using them.
1. Wallpaper wall covering.
When decorating, many people choose to put wallpaper and wallcovering on the wall in order to decorate the wall. In this way, not only can the walls be decorated with our favorite patterns, but also prevent the big white from being directly exposed to the outside, protecting the big white from being damaged in our daily life.
But they didn't expect that in fact, wallpaper wallcovering is one of the materials with the highest formaldehyde content in all wall decorations.
After plastering the wallpaper wallcovering on the wall, I believe that everyone has smelled a pungent smell in the room, but in fact, part of the smell is caused by formaldehyde.
The reason why wallpaper wallcovering can be firmly pasted on the wall is mainly because it contains a lot of glue, and glue is where formaldehyde hides!
To be honest, instead of sticking wallpaper and wallcovering on the wall, it is better to paint latex paint directly, of course, if you want to do without a little formaldehyde, then it is best to use white directly.
2. Composite granular wood
Decorating a new house is indispensable to install cabinets, wardrobes and the like, at this time you need to use wood to customize, but now the wood materials on the market are rich and diverse, and the difference is also quite large.
Generally, when we choose wood materials for making furniture, it is nothing more than solid wood and composite grain wood, which is naturally good and expensive.
And the composite grain of wood we are wantingUse sparinglyAfter all, it is made of various materials bonded together and containedMore formaldehyde
3. Brightly colored textiles
Some people may not understand when they see this, why does formaldehyde also appear in textiles? There is definitely no formaldehyde in plain textiles, but here is a premise, "brightly colored" textiles.
Like the red and purple curtains at home, the red ** and bed sheets on the bed, these contain more formaldehyde! Almost all of the brightly colored textiles we see on the market are dyed with dyes, and the fuel contains a lot of formaldehyde! Moreover, the darker the color, the greater the concentration of formaldehyde!
Therefore, when we choose curtains, bed sheets, leather sofas, etc., as long as there are textiles, we should try to choose plain colors. Less formaldehyde, safe to use, we are more assured!
4. Plush toys
Unexpectedly, the plush toys bought for children also contain formaldehyde. In fact, plush toys contain more formaldehyde than we imagine, especially some cheap plush toys, which may contain a large amount of formaldehyde in their raw materials, and plush needs to be glued to the frame, which also makes plush toys logically become "formaldehyde big".
Therefore, we usually try to buy plush toys for children as little as possible, even if they do, don't be greedy for cheap, and be sure to buy regular and qualified products.
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", and if you live in the same room with these "release originals" for a long time, our health will be easily threatened, don't take it seriously!
1. Smell the smell of gas
Formaldehyde is an organic chemical that is a colorless, pungent odorous gas. So, if you smell it at homeA pungent smell that makes you feel uncomfortableThen it is time to pay attention to the formaldehyde concentration in the roomIt's likely to be exceeded!
At this time, don't take it lightly, let the smell go and treat it as if nothing happened, which may cause more harm. Be sure to quickly leave the environment where formaldehyde exceeds the standardFirst of all, ensure your own safety, and secondly, do a good job of formaldehyde removal measures.
Is it safe if it doesn't smell? Sometimes when you can't smell a pungent smell in the room, it's not really tasteless, it's just that you can't smell it. Formaldehyde has an odor threshold, as the name suggests, it is not present to smell, but needs to reach a certain concentrationFormaldehyde odor threshold is exceeded before it can be smelled. And people's sensitivity to odors is different, possiblyWhen you smell the odor, the formaldehyde has exceeded the standard several times.
In general, when there is a pungent odor, the indoor formaldehyde concentration is likely to exceed the standard, and when there is no odor, don't take it lightly, especially after the decoration.
2. Look at animals and plants
In the environment where formaldehyde is "infested", animals and plants will suffer, so we can also analyze whether formaldehyde exceeds the standard by observing the state of animals and plants.
In an environment where formaldehyde exceeds the standard, plants even in the case of sufficient sunlight and sufficient waterThe leaves will still turn yellow, wilt, and even witherIf you have this symptom, you should consider whether the indoor environment is polluted.
Small animals are also sensitive to formaldehyde, if they have just moved into a new home or have just been renovated, small animals in the homeSuddenly very wilted, sluggish, and inactive, you should also pay attention.
However, this process is relatively slow, and it is also greatly affected by the environment and man-made. It's just one of a kindAuxiliary distinguishing methods should not be used as a basis for judgment, which is easy to have the opposite effect.
3. Look at the body
When people are in an environment where formaldehyde exceeds the standard for a long time, the human body will gradually be attacked by formaldehyde, and then the immunity will decrease, and it will begin to be prone to disease. If you move into a new home,Always have a cold, fever, or ** start to have allergic symptoms, then you must be vigilant.
If the human body is in an environment where formaldehyde exceeds the standard for a long time, then a large amount of formaldehyde will be inhaled when breathing, and then it will appearFrequent coughing and sneezing。It needs to be reminded that everyoneDon't confuse these symptoms with a cold.
Our ** and respiratory tract are more sensitive to formaldehydeIf you stay indoors with excessive formaldehyde for a long time, you will show various symptoms.
For example, when you wake up every morning, you feel suffocated, nauseous, and dizzy;
No one smokes, but often feels uncomfortable in the throat, has a foreign body sensation, and has difficulty breathing;
Family members often catch colds, and the elderly or children often cough, sneeze, and have weakened immunity;
Family members often have allergies and other diseases, causing allergic reactions such as itchy skin and small red spots;
The most important thing is that the family stays indoors with excessive formaldehyde for a long time, willCluster symptoms are exhibited, and after getting out of this environment, they will get better.
There is a very peculiar "magic method of removing aldehyde" circulating on the Internet, that is: if you want to remove formaldehyde for new furniture, then use the characteristics of formaldehyde soluble in water, you only need to wipe the furniture with water, back and forth several times a day, after a period of time, the formaldehyde of the furniture can be dissolved by water.
From a professional's point of view, this is simply a strange theory, although formaldehyde can indeed be soluble in water, but the formaldehyde of furniture will not be dissolved because you wipe it with water a few times.
What is the reason for this?
1. The evaporation rate of water is relatively fast
Under normal circumstances, water will evaporate quickly, especially in summer, the water evaporates faster, at this time, often not much formaldehyde is dissolved, and the water has already evaporated in the air.
2. This water can only dissolve a very small part of formaldehyde
After reading the above, someone may tremble and say, "Then I keep the surface of the furniture moist all the time, then it should always be okay, right?" Even if water is applied to the exterior of furniture and kept moist for a long time, it can only touch a small part of the formaldehyde dissolved in the air, and more formaldehyde is still permeated in the indoor air.
Unless, soak the whole house in water.
3. Formaldehyde is exuded from the inside of the furniture material, not from the outside
No matter how much we wipe and keep the furniture moist, we are only working on the outside of the furniture, and in fact, we can't touch the real area of formaldehyde - the inside of the furniture material (unless the furniture is destroyed and soaked in water, but is this possible?). ）
So, to summarize the above reasons, wiping furniture with water, no matter how diligent you wipe, is powerless to remove aldehydes.
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!
In fact, it is not very difficult to remove formaldehyde, and the choice of the right product is already half the success.
It is recommended that you choose such a fast and visual [Activated carbon to remove formaldehyde discoloration balls]., I'll introduce you to its awesomeness!
