This year's 3-year-old Xiaobei (pseudonym) frequently caught colds and fell ill, at first parents thought that the child was young and weak, and did not pay enough attention until the symptoms became more and more serious...
A few days ago, Xiaobei was diagnosed with leukemia in the hospital. It is understood that Xiaobei had lived in a new house that had been renovated for less than three months before being diagnosed, and the doctor considered that the formaldehyde in the decoration materials affected the child's health and induced leukemia.
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 three years old, what a sin!
After the incident, after testing, the new house they lived in seriously exceeded the formaldehyde standard!
The survey found that as many as 70% of the families who moved into the house for 3-15 years still exceeded the formaldehyde standard!
There are two main reasons for this:
1. Superimposed pollution at home
Superimposed pollution can be simply understood as an additive problem. The measurement standard of formaldehyde is based on the whole room, and the use of environmentally friendly furniture does not represent the overall formaldehyde content of the room.
10 pieces of furniture that meet the formaldehyde standard may create a space with excessive formaldehyde. Any decoration materials and furniture will contain a certain source of pollution to a greater or lesser extent, and will be released slowly over time.
2. Formaldehyde itself lasts for a long time
The harm caused by decoration pollution should not be underestimated, many people know that formaldehyde volatilization time can be up to 15 years, but most people do not know why there is such a long release cycle, and even have doubts.
The reasons why formaldehyde has risen instead of falling for a year in a new house mainly include three aspects:
1. The quality of building materials is poor
In order to pursue profits, some unscrupulous businesses use inferior materials for decoration. These materials have high formaldehyde content and a long release cycle, which will continue to release formaldehyde even when it is empty.
2. The indoor environment is airtight
After the renovation of the new house is completed, the formaldehyde concentration gradually increases due to the closed doors and windows and the lack of indoor air circulation. During the one-year vacancy period, due to insufficient ventilation, the formaldehyde concentration remained even higher.
3. The influence of temperature and humidity
Temperature and humidity also have a great influence on formaldehyde release. In a high temperature and high humidity environment, the release of formaldehyde will increase. As a result, formaldehyde concentrations may be higher in new homes during the summer or rainy season.
Many people think that formaldehyde is far away from us, but in fact, as an expert environmental expert pointed out: a few inconspicuous things in the house are formaldehyde households, and you must be careful when buying and using.
"Formaldehyde big households" have been exposed: don't buy these 4 kinds of "daily necessities" at home, and "release formaldehyde" every day
1. Oil-based latex paint
Oil-based latex paint contains a large amount of formaldehyde, and if oil-based paint is used during decoration, formaldehyde will be difficult to volatilize in the new home.
Therefore, do not use oil-based paint to paint the wall, try to use water-based topcoat and primer.
2. Complex wallpapers
We all know that when decorating, many of us will not choose simple paint, but will choose a variety of patterns, very complex wallpaper, wallpaper patterns are more, and it looks magnificent, in line with many people's aesthetics.
But complex wallpaper, in the process of making there are also some plants and trees, glued together, these glues also contain formaldehyde, wallpaper also needs to be watered to smear, pasted on the wall, in order to gradually firm and smeared These glues also contain a lot of formaldehyde, so you must be cautious when choosing wallpaper and watering.
3. Colorful curtains
When making curtains, in order to make it colorful and look good, a large number of dyes will be added during the printing and dyeing process, and these dyes usually contain formaldehyde, therefore, the curtains of the finished product are prone to formaldehyde residues.
It is recommended that the newly bought curtains should be soaked in water and cleaned to dissolve and release formaldehyde, which can greatly reduce the risk of formaldehyde.
In addition, when buying curtains, try to avoid colorful styles, and it is best to choose cotton, linen, silk and other pure natural materials, which are safe and hygienic.
4. Auxiliary materials such as sewing agents
Sometimes people are easy to fall into the misunderstanding, thinking that only some large materials will produce formaldehyde, in fact, some small or auxiliary decoration materials or accessories also contain a large number of harmful gases, such as auxiliary materials such as sewing agents.
In fact, those who have used the beauty sewing agent know that he has a pungent smell, because it also has harmful substances such as V o C and formaldehyde, which is no less dangerous / harmful to the body/health/than latex paint, so be careful when using, if you do not pay attention, it will also constitute a threat / threat / threat to our / health / health.
It is said that formaldehyde is harmful to human health and safety, and what aspects will the impact be reflected in?
Excessive formaldehyde will affect the human respiratory system, nervous system, skin and other parts, and the most important thing is that formaldehyde can cause cancer.
Inhalation of formaldehyde can directly affect the human respiratory system
Formaldehyde is relatively soluble in water, because the upper respiratory tract of the human body is relatively moist, most of the formaldehyde inhaled into the human body is absorbed in the upper respiratory tract, and a small part will enter the human lungs, causing lung discomfort.
As a result, symptoms of upper respiratory tract infections appear: such as sneezing, coughing, etc. This is also the first manifestation of formaldehyde inhalation in the human body, and the most direct manifestation of long-term exposure to formaldehyde residue in the room is to cause rhinitis and asthma.
Formaldehyde can cause degeneration and necrosis of the nervous system
According to studies, formaldehyde can cause degeneration and necrosis of the nervous system, and people who are exposed to formaldehyde for a long time (such as anatomists) may have different degrees of headache, memory loss, reduced sensitivity, reduced coordination function, sleep disorders and other symptoms.
This is also the reason why the hospital dissection room focuses on the treatment of formaldehyde, and the hospital dissection room seals the pathological test samples with "formalin", which is a diluted solution of formaldehyde, and the formaldehyde in the dissection room exceeds the standard by nearly 1,000 times under normal circumstances.
It can cause skin lesions and allergy symptoms
According to research, direct skin contact with formaldehyde will cause skin itching, slight rash and other allergic symptoms, especially for patients with dermatitis or eczema, and it is easy to aggravate the condition in an environment where formaldehyde concentrations exceed the standard.
We must understand that formaldehyde removal is not a project that can be completed in a short period of time, formaldehyde emission time is generally 3-6 months, it is necessary for us to continue to remove formaldehyde.
1: Alvis formaldehyde scavenger is a highly efficient indoor air purifier, specially designed for formaldehyde, benzene, ammonia and other harmful substances. Its excellent scavenging efficiency can quickly penetrate and capture formaldehyde hidden inside structures such as plates, and then quickly decompose it into harmless carbon dioxide and water, and this decomposition process itself does not produce new harmful compounds, so it can effectively prevent the volatile release of formaldehyde from the source.
The ingredients of Alvis formaldehyde scavenger are safe and reliable, free of oxidants, alcohol and fragrances, and are very safe for families. Tested by professional testing institutions, the efficiency of this product to remove formaldehyde is as high as 91%, which is a favorable player for removing formaldehyde.
2: Activated carbon:
Activated carbon itself has a certain effect on the adsorption of harmful substances and volatile harmful gases, so it can be used to effectively adsorb formaldehyde, especially in the newly renovated indoor environment or in the case of excessive formaldehyde, it is an effective choice.
Three: Yiya formaldehyde deep scavenger: The composition of this formaldehyde scavenger is mild, which effectively improves the free state and the formaldehyde inside the plate, and the decomposition products are pollution-free.
