It exists in air in the form of gas. When it comes into contact with human skin or is inhaled into the body, it will cause formaldehyde poisoning, and many inducing factors of leukemia are formaldehyde.
Formaldehyde is not only hidden in newly renovated houses, but also may be carried in many foods. Therefore, for those children with weak constitution and poor immunity, parents and friends must keep their children away from foods carrying formaldehyde, such as the following.
Which foods are easy to add formaldehyde?
Generally speaking, formaldehyde plays a more important role in bleaching solution, antisepsis and sterilization. Therefore, some unscrupulous companies may illegally add formaldehyde components such as sodium formaldehyde in fresh noodles, pig's feet, squid, tripe and shutters (five ingredients).
On the other hand, in the process of buying these foods, we also need to pay attention. Food is the most important thing for the people, and food safety comes first. Refuse food with safety risks, which is the first thing we need to consider when buying food.
Harm of formaldehyde:
Fundamentally speaking, formaldehyde is a gas without color and choking smell, and it is easy to cause formalin solution when it meets water. After ingestion, it will first harm the respiratory mucosa and respiratory tract, and long-term exposure will increase the risk of throat cancer.
The intake of formaldehyde has great stimulation and harm to the digestive system, leading to nausea, retching, nausea and vomiting. More serious cases will damage renal function, leading to fetal malformation and side effects; In addition, the supply of formaldehyde will once again increase the risk of various cancers (including sepsis), and for women, the risk of menstrual disorders and infertility will also increase again.
If the noodles or other foods you buy have obvious pungent smell or chemical smell, it means that there is something wrong with the food. Please don't buy them because formaldehyde is highly volatile.
Take a closer look at the ingredients you choose. If its color has exceeded its milky white and its volume has obviously expanded, it can be treated with formaldehyde.
How to distinguish fresh noodles with white pieces?
All normal fresh noodles are milky white or light yellow with a certain brightness; The fresh noodles with white bleach are generally brown or brown, and the color is dim.
All normal fresh noodles have the original flavor of whole wheat flour, and fresh noodles with white block bleach will have sour or even musty taste.
How to avoid buying "food containing illegal formaldehyde"?
First of all, this method of identifying formaldehyde, which is familiar to customers in daily life, is unreliable and extremely infeasible to distinguish formaldehyde food categories.
Secondly, in order to avoid food safety risks, please go to regular supermarkets or large farmers' markets to buy food. Such local supervision will be stricter and the claim punishment process will be more perfect. Even if you buy unqualified products, you can defend your rights reasonably.
Finally, please eat more ingredients, reduce the intake of some ingredients, and try to avoid the risks of food quality, safety and security. In addition, formaldehyde is a volatile component at high temperature, and all components must be completely heated before taking it to reduce the risk.
In addition to nutrition, these three insignificant daily necessities are still formaldehyde seedlings.
1, wallpaper
Nowadays, the perfectionist fashion trend in our daily life. For example, some newly renovated houses will also choose to paste some wallpapers, and wallpapers of various design styles can be removed and replaced at will. As we all know, in the process of making wallpaper, in order to make the color more beautiful, we will continue to add a lot of formaldehyde for coloring.
If you use this wallpaper for a long time, it will also lead to excessive inhalation of formaldehyde, which will harm your health. For example, wallpaper is also formaldehyde seedling stage, so I suggest you deal with it better.
2. Mattress
In order to better improve the quality of sleep, many people choose soft mattresses, which can also enhance the sense of experience, usually changing mattresses every three months.
As we all know, I don't know that in the production process, in order to better improve the soft formaldehyde of the mattress, the plastic film on the surface of the mattress is treated and the formaldehyde content is relatively high.
If you use this mattress for a long time, it will also harm your health, so I advise you to handle it well and don't care.
3. Curtains
When decorating a house, interior decoration is usually the mainstay. For example, curtains are only bought when you check in. When considering shading and beauty, we will choose some curtains with deeper pigments and thicker fabrics.
This kind of curtain will add a lot of compounds to color during the production process, which contains a lot of formaldehyde. Long-term contact with such curtains will also endanger personal health. Therefore, when everything is normal, try to choose some simple colors.
Therefore, just like some ingredients or daily necessities, they all contain formaldehyde. It is recommended that you take preventive measures as soon as possible to avoid long-term contact and damage your health.
It is suggested that we should open more windows when we are at home, which can remove the formaldehyde left by our decoration to a certain extent, and the newly bought furniture at home also needs to be wiped with salt water. You can also put it on the balcony for ventilation.
You can also put some auxiliary tools from in addition to formaldehyde at home, which can help you remove formaldehyde to some extent.
It is strongly recommended that you give it a try-in addition to formaldehyde manganese-carbon package, which is also a popular research method of in addition to formaldehyde manganese-carbon package in Tsinghua University Institute of Natural Environment.
A few years ago, an awesome professor in Tsinghua University led the team to develop this aldehyde-removing manganese-carbon package.
Although it looks flat, its adsorption capacity is many times that of ordinary activated carbon.
It can also decompose formaldehyde into harmless water and carbon dioxide, and the aldehyde removal rate is super high!
Almost all the friends I have used online are very popular-
Although many people know that it is easy to use, few people know that it is actually hard to come by.
When the news about the harm of formaldehyde emerged one after another, the "863 Program" of the Ministry of Science and Technology handed over the problem of indoor pollutant purification to Tsinghua University Environmental Research Institute, and appointed Professor Zhang as the chief expert of the project.
In the seven-year R&D struggle, they found an "aldehyde-removing nemesis"-active manganese.
In addition, they also found "modified activated carbon" with stronger adsorption capacity than ordinary activated carbon.
Manganese as the skin and carbon as the core can decompose formaldehyde while absorbing, which can effectively avoid secondary pollution.
Therefore, Professor Zhang decided to use these two technologies to lead the team to make a "formaldehyde removal artifact" that can protect everyone from formaldehyde.
This is what is in front of us.
After the research results came out, many professors of environmental studies praised them.
Is it really that powerful?
We specially went to the laboratory of Tsinghua University Environmental Research Institute, and let the seniors demonstrate for us in person, and found-yes, it's really amazing!
We were really surprised when we went. Their laboratory is really awesome, with all kinds of equipment. It is said that high maintenance costs are needed every year.
But the results of these devices are beyond doubt.
In order to verify its aldehyde removal ability, we did an experiment. Inject formaldehyde into the sealed cabin, then quickly put it into two bags of manganese carbon, and record the initial value:
Formaldehyde: 19.6ppm, carbon dioxide: 6 10ppm.
19. 1ppm formaldehyde content exceeds the national safety standard by more than 300 times. As soon as the lid was closed, the formaldehyde value in the cabin dropped rapidly.
After 5 minutes, formaldehyde: 0.5ppm and carbon dioxide: 706ppm.
The concentration of formaldehyde and carbon dioxide in manganese-carbon package was from 19.6ppm to 0.5ppm, and the formaldehyde content decreased by 93% in just 5 minutes!
As a in addition to formaldehyde product, this manganese-carbon coated in addition to formaldehyde is really good! And the effect can last for at least 9 months. Compared with similar products that have to be replaced in two or three months, the cost performance is more than one or two points higher!
After careful understanding, I realized that its built-in modified activated carbon was originally carbon particles that had been used in gas masks.
After unbonded molding and twice activation, the number of micropores and adsorption capacity of this kind of carbon are many times that of ordinary activated carbon.
It can not only absorb a variety of free harmful gases faster at the same time, but also intercept harmful molecules to prevent them from escaping and harming the human body.
Coupled with the super-decomposed manganese skin, put it at home and in the car, the more harmful gases, leather and other smells, they will be like "a long drought meets the rain" and try their best to swallow and decompose until the toxic gases disappear.
In fact, before I knew about this aldehyde removal package, a friend recommended me to use activated carbon, and I never dared to use it.
Because ordinary activated carbon adsorbs slowly and the weather is a little hotter, formaldehyde volatilizes faster than adsorption, so it is inevitable to be absorbed by human body.
Moreover, the validity period is only 2-3 months, so it should be aired frequently, otherwise the toxic gas will be released again after saturation, causing secondary pollution.
But this aldehyde removal bag is different. It combines manganese and carbon, and decomposes while adsorbing. 1 The package can be used for 9 months, up to half a year!
The comparison data is calculated by the production company's experiments, and the right of interpretation is reserved within the legal scope.
One bag 10 bag, the purification area can reach 20.
For the average family, 1 bags are kept in every corner and cupboard at home, and it is just right to buy 4 bags.
Put 1-2 bags under and behind the seat in the car to absorb formaldehyde and odor.
Shoe cabinets, wardrobes, bedside tables, cabinets ... especially wooden homes, you should put more bags.
Also remember to put it under the bed and at the foot of the bed.
Formaldehyde in cracks in the floor is particularly volatile. Put a bag in the corner and the smell at home will be fresh.
Of course, if you just bought a new car or new furniture, or your home has just been renovated, the formaldehyde concentration is extremely high at this time. It is recommended to put 2 more bags, and the effect will be more obvious.
When delivered to you, each package has a small sealed package to ensure adsorption activity.
Many offline aldehyde removal services essentially use products with the same principle to remove aldehydes, so the price of several hundred pieces of manganese carbon packages in the whole house is much more valuable than the average cost of more than 5000+ by professional teams.
After opening, the manganese-carbon package inside is hot-pressed and sealed, and the carbon particles in the inner core will not leak out at all.
Turn on the air conditioner in summer, and it is cold in autumn and winter, but close the doors and windows, and formaldehyde is also gathering in large quantities, waiting for an opportunity.
Everything can be saved, but the health of yourself and your family must not be saved.
It is more important than anything to spend 100 yuan on in addition to formaldehyde to gain peace of mind and health for yourself and your family for a whole year.
And it also has a bonus item, no flavor added, no taste at all.
Ordinary charcoal bags of twenty or thirty dollars on the market are really cheap, but they have no effect. Buying them is tantamount to throwing away the money.
Compared with them, this in addition to formaldehyde manganese charcoal bag is a little expensive, but the money is really spent on the blade!
Especially for families with children, pregnant women and the elderly, don't hesitate to clean up the formaldehyde as soon as possible.
Two cups of coffee can protect the health of you and your family. It is worthwhile to spend a little money to solve the big trouble!
