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!
If a child has leukemia, it is a bolt from the blue for a family!
Why do we all know the dangers of formaldehyde now, but the excessive formaldehyde incident still occurs peacefully?
It's not because they don't pay attention to the removal of formaldehyde, but many people don't realize that they are in formaldehyde!
Is formaldehyde only available in new houses?
Many families will have a misunderstanding that a house that has been renovated for several years should be free of formaldehyde.
But in fact, formaldehyde pollution is not only in newly renovated houses, even in houses that have been occupied for two years or more, formaldehyde may still be present.
Because the release period of formaldehyde is slow, and the volatilization period reaches 3-15 years, it is important not to think that formaldehyde is only available in new houses.
Formaldehyde is widely used, often found in decoration materials, chemical industry, wood manufacturing industry, textile industry, antiseptic solvents and other places, its main hazard is to have an irritating effect on the skin and mucosa. And when the formaldehyde reaches a certain concentration, the human body will feel uncomfortable, and the concentration greater than 0.08 cubic meters is easy to cause itchy eyes, red eyes, throat discomfort, weakness, wheezing, dermatitis and other conditions.
Generally, the newly renovated room has the highest formaldehyde content, which is the cause of many diseases, excessive formaldehyde will cause regenerative blood disease, lymph / bara / sex white / blood / disease, lymph / bar, cancer / for pregnant women will cause fetal shape, miscarriage / birth, children's mental decline and other symptoms.
What is the standard range for indoor formaldehyde testing?
According to the mainland's regulations on the human living environment, the indoor formaldehyde content should not be higher than 0.08mg/m³, and those exceeding this range are excessive formaldehyde, and it is not recommended to stay.
Therefore, if the indoor formaldehyde content is in the range of 0.1-0.2mg/m³, it is best to take some effective measures to reduce the formaldehyde content to the standard before considering moving in.
There are two main regulations on indoor air quality in China:
The first is the "Indoor Air Quality Standard" GB/T18883-2022, which requires that the minimum standard for human living environment is formaldehyde content ≤0.08mg/m³;
The second is the "Code for the Control of Indoor Environmental Pollution in Civil Buildings" GB50325-2020, which requires the indoor formaldehyde content of Class I civil construction projects to be ≤ 0.07mg/m³, such as residences, kindergartens, schools, etc., and the indoor formaldehyde content of Class II civil construction projects ≤ 0.08mg/m³, such as gymnasiums, restaurants, libraries, etc.
What are the specific aspects of formaldehyde harm to children?
- Irritating effect: when the formaldehyde content in the indoor air is 0.1 mg/cubic meter, there will be peculiar smell and discomfort; when it reaches 0.5 mg/m3, it can irritate the eyes and cause tearing; up to 0.6 mg/m3, it can cause throat discomfort and pain. At higher concentrations, it can cause nausea and vomiting, coughing, chest tightness, wheezing and even pulmonary edema, and at 30 mg/m3, it can cause immediate death.
- Sensitization: Exposure to a certain dose of formaldehyde can cause allergic dermatitis and induce bronchial asthma, and in large quantities, it can cause allergic purpura, which is a recognized allergen.
- Carcinogenic and cancer-promoting effects: Formaldehyde has been found to cause gene mutations and chromosomal damage. Continuous exposure to high concentrations of formaldehyde in experimental animals has led to an increase in the incidence of a variety of tumors, and there has been conclusive evidence that formaldehyde causes nasopharyngeal carcinoma in occupationally exposed people. In 2004, the International Agency for Research on Cancer (IARC) listed formaldehyde as a carcinogen identified in humans and believed that there was a causal relationship between formaldehyde and the occurrence of leukemia.
Can ventilation be effective in removing formaldehyde?
For the health of our families, we must remove formaldehyde in a timely manner, but before that, we must understand that formaldehyde removal is not a project that can be completed in a short time, and the formaldehyde emission time is generally 3-6 months, so we need 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.
