How long does it take to get sick in a formaldehyde contaminated room

If you live in a house with excessive formaldehyde for about 3 months, you will get leukemia.

People inhaled 60 120 mg m, bronchitis and severe lung damage occurred; Long-term, low-concentration exposure to formaldehyde can cause headache, dizziness, fatigue, sensory impairment, decreased immunity, and drowsiness, memory loss or neurasthenia, and mental depression; Human inhalation of 12 24 mg m, severe burns, tearing, cough of the nasal and pharyngeal mucosa; Long-term exposure to formaldehyde can cause respiratory dysfunction and hepatic toxic lesions, which are manifested as hepatocyte damage and abnormal hepatic radiation energy. 10 20ml orally for man, lethal.

You can't spend more than six hours a day in a formaldehyde house.

Formaldehyde is a relatively volatile substance, but the volatilization process is very slow, because the volatilization temperature required for formaldehyde is 19, only when the indoor temperature reaches 19 degrees, formaldehyde will begin to volatilize, the higher the temperature, the faster the formaldehyde volatilizes.

If the indoor temperature does not exceed 19, then the indoor will always contain a large amount of formaldehyde, which is difficult to volatilize, among which the living room and bedroom are the places where formaldehyde is most likely to exceed the standard. Many owners are in a hurry to move in after renovating their houses and ventilating them for 3 months, but ventilation for 3 months is actually not formaldehyde.

Formaldehyde removal:

1. Maintain indoor air circulation. It is normal for the formaldehyde to exceed the standard in the newly renovated house, and it generally takes more than ten years to completely remove the formaldehyde, but the feasibility of this method is low, because the house cannot be idle for a long time, so the ventilation method is effective but long. Combine other methods to reduce time.

2. Now the more authoritative and reliable method is to use the method of physical adsorption, which is the method of chlorobenzene adsorption. Because some studies have shown that the chlorine atom on the benzene ring of this chlorobenzene has strong electrical absorption, it can combine with the functional groups on the formaldehyde to further decompose formaldehyde and achieve effective removal of formaldehyde, this research is a major breakthrough in the treatment of formaldehyde.

3. Use the usual edible vinegar fumigation method, because vinegar presents a weak acid nature, it will react with ammonia in the air, but will not react to release harmful gases, and due to the low cost, many people are willing to try, and this method is also recommended here, hoping to effectively control formaldehyde.

4. Remove formaldehyde with photocatalyst. In the presence of light, the photocatalyst produces a reaction similar to photosynthesis that is done with light as a catalyst, and the products of the reaction are oxidizing reactive oxygen species and free hydroxide groups. It can oxidize and decompose some toxic gases, bacteria and other harmful substances, and the effect of formaldehyde treatment is also great.

The human body will be greatly affected, because formaldehyde will poison people's blood, or don't stay in the house with formaldehyde.

The incubation period of formaldehyde is officially given by 3 15 years, which shows that this time period is very uncertain, the difference is very large, and the content of formaldehyde in indoor building materials and furniture, and the ventilation conditions of the home are closely related. It shouldn't be as long as 15 years, but it's dangerous for 3 years, so be careful.

Relevant data show that indoor air pollution is 5 10 times higher than that of outdoors, and there are more than 500 kinds of pollutants. Indoor air pollution has become a cause of many diseases, and formaldehyde is a major aspect of indoor air pollution.

This question is not very accurate, if you ask about the release cycle of formaldehyde after decoration, it ranges from 2 weeks to 15 years.

If you ask about formaldehyde in the air in a house, then open the window for ventilation for 10 minutes and it will be gone.

There are many sources of formaldehyde pollution, which can be divided into short-term and long-term. Wall paint, wallpaper, curtains, fabric sofas, etc. are short-term sources of pollution, and the release period ranges from 2 weeks to half a year, and will not exceed 2 years at most. The adhesives used in wood-based panels and furniture containing wood-based panels are long-term pollution sources, and the cycle of formaldehyde release is as long as 3-15 years.

1. How many years does formaldehyde be released at home?

The release life of formaldehyde is very long, it can reach 3 to 15 years, and it is difficult to be completely removed in a short time. Formaldehyde is still very harmful to our human body, so we must choose products with formaldehyde content that does not exceed the standard when choosing materials.

Second, the method of removing formaldehyde.

1. Open window ventilation method.

Although ventilation is the way to remove formaldehyde in daily life, ventilation should also be emphasized*, because effective ventilation can better remove formaldehyde.

When you take the window ventilation to remove formaldehyde, you should open the drawer cabinet doors and volatilize the formaldehyde through air convection. To improve ventilation, you can place a blower or floor fan in the room to speed up air convection by shaking head mode.

2. Activated carbon adsorption method.

Because activated carbon has strong adsorption, it can indeed remove formaldehyde. However, it must be noted that the working mechanism of activated carbon aldehyde removal is passive physical adsorption, which can only reduce the free formaldehyde in the air, and cannot penetrate deep into the furniture board to solve the formaldehyde problem from the root.

At the same time, in the process of using activated carbon to remove formaldehyde, when the activated carbon is fully adsorbed, it must be replaced, otherwise the activated carbon can not only continue to adsorb and remove aldehyde, but also may cause desorption of pollutant substances and even secondary pollution.

Definitely! Severe cases will get leukemia, so excessive formaldehyde content in the air must be dealt with in time, and more windows must be opened for ventilation!
