Nowadays, people pay more and more attention to indoor environment, especially formaldehyde. This is mainly because more and more studies show that formaldehyde is the main cause of childhood leukemia. Even, a study shows that more than 90% of children with leukemia have been decorated at home, and many of them are finely decorated.
These symptoms of children may be excessive formaldehyde at home. Don't be careless, let's have a look!
More and more medical research shows that indoor formaldehyde is directly related to the onset of leukemia, and now children with leukemia are showing a trend of younger age, which has to make freshmen wary.
Therefore, if your child has the following circumstances, don't take it seriously, and take the child to the hospital for examination in time to prevent the child from formaldehyde poisoning.
First, chest tightness and shortness of breath
Under normal circumstances, children with mild formaldehyde poisoning will have chest tightness and shortness of breath. If you just move into a new house, your child will feel chest tightness and shortness of breath. Don't underestimate it. This is probably formaldehyde poisoning.
We will take our children to the hospital to check whether the formaldehyde at home exceeds the standard. After the renovation of the new house, we'd better ventilate for a month to reduce the pungent smell and formaldehyde in the room. However, if the indoor air still smells after ventilation, some measures must be taken.
Second, eye discomfort.
Eyes are very sensitive to formaldehyde, especially children. If the formaldehyde in the air exceeds the standard, the child will have symptoms of eye discomfort.
The general symptoms are dry eyes, itching and so on. If this situation is alleviated outdoors, the high probability is caused by excessive formaldehyde.
Third, resistance drops, and people love to get sick.
Although children's resistance is much worse than that of adults, if children are found to be often ill recently, they need to be taken seriously.
After all, formaldehyde will hurt children's resistance and make them more likely to get sick. If you find that your child is frequently ill, be sure to check whether the formaldehyde content in your home exceeds the standard.
Fourth, lethargy and weakness.
Formaldehyde will attack people's nervous system and make them sleepy. Living in an environment with excessive formaldehyde for a long time will lead to poor mental health and exhaustion.
If the child is sleepy and weak, he must pay attention to it and not be careless.
Fifth, little red dot appears on the skin.
There is another situation that is obvious. Children's local skin exposed to the air will be allergic, which may be little red dot or eczema, probably caused by the skin being stimulated by formaldehyde. If this symptom occurs, the child will feel itchy and will often scratch. It's time to take the children to the doctor!
If you really find that your child has these symptoms, don't be too nervous and don't turn a blind eye. The best way is to take the children to the hospital for examination. If it is caused by formaldehyde, try to control formaldehyde at home. If we want to solve the problem of formaldehyde, the experts gave us two suggestions.
First, strong ventilation
The density of formaldehyde is higher than that of air, so children are the group that want to be attacked by formaldehyde most. The traditional ventilation in addition to formaldehyde method has a slow effect. To remove formaldehyde faster, the best way is to increase the ventilation intensity with an electric fan.
We can buy industrial fans. If you think industrial fans are relatively large, you can use household fans, buy more and turn them on to strengthen ventilation.
Second, the use of scientific in addition to formaldehyde.
The problem of formaldehyde has been bothering people for a long time. Ventilation or enhanced ventilation will still be affected by certain weather factors, and it can't really completely remove formaldehyde. Only using scientific in addition to formaldehyde is the best solution.
As early as 20 19, we had a professional test on five in addition to formaldehyde products which were widely praised and sold well in the market.
Finally, it is found that manganese-carbon coating and aldehyde removal spraying are the best.
Coincidentally, the technologies behind the two products are from Tsinghua University Environmental Research Institute.
So we found that the country has long realized the universality and seriousness of formaldehyde problem.
Therefore, in the 863 Program of the Ministry of Science and Technology, "indoor air improvement" is listed as the key, and Tsinghua University is the lead unit.
Among them, Tsinghua University Environmental Research Institute is responsible for formaldehyde control, and the technology of active manganese and amino acids is the result of this plan, so Professor Zhang, the patentee, also made an explanation on CCTV- 1.
After numerous uninterrupted experiments, it is finally proved that 1 g bamboo charcoal activated carbon can adsorb 23 micrograms of formaldehyde;
1 g "Decomposition of formaldehyde by active manganese" can decompose 33,300 micrograms of formaldehyde, and the in addition to formaldehyde amount is 1000 times that of activated carbon.
This is a very important research achievement in the field of "removing excessive formaldehyde" in China. It is also the source of the manganese-carbon package we brought this time!
We quickly contacted Professor Zhang and his team in Tsinghua University and came to Tsinghua University Institute of Environment.
Whether it is useful or not depends on this "abnormal" experiment. Last year, in the same place, we came to the environmental chemistry laboratory of the environmental materials research platform for real testing.
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!
So we contacted the manganese carbon package team and brought the upgraded new model.
This time, the new manganese-carbon package went on the market. In addition to more environmental protection and brand-new packaging, the bigger upgrade is in the composition.
By adjusting the proportion and composition, the active manganese content of 15% is increased, and the purification effect is improved. The same amount of manganese-carbon bags can "absorb" more formaldehyde and harmful gases than in previous years. The outer layer is still non-woven, which can isolate bacteria and be cleaner and more hygienic.
The inner core is 9 12mg/g activated carbon with high iodine value, which has stronger adsorption capacity.
The upgraded manganese is perfectly combined with carbon with stronger adsorption, and formaldehyde can be decomposed into carbon dioxide and water while being absorbed.
Every bag you get is 40g. After a package is unpacked, the efficient aldehyde removal period is half a year, and the usable area is 20.
Usage: put it in wardrobe, locker and other cabinets to consume odor continuously, or put it on the surface of objects.
Note: the function of manganese charcoal bag is to continuously purify formaldehyde and accelerate the consumption of formaldehyde, which is not immediate. It is recommended to use it with window ventilation.
In addition to my own use, it is also arranged for my parents and friends around me!
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.
The money for two cups of coffee ensures the health of yourself and your family, and it is worthwhile to spend a little money to solve big troubles.
