1, high temperature environment in summer can accelerate formaldehyde volatilization.
2. Plants have a strong ability to absorb formaldehyde, such as cactus, chlorophytum, reed, ivy, cycad, chrysanthemum and so on.
Three. Be sure to open all the doors and drawers of the furniture and all the windows of the room, and add some fans to speed up the air convection.
4. Activated carbon: Ye Guang mud material is used to absorb the polluted gas, which effectively decomposes the internal formaldehyde pollution and has a long-term effect.
5. Generally speaking, Huankang nano-aldehyde-removing enzyme has a good effect, so it is best to use this condition.
Four methods of formaldehyde detection in ordinary families
1. formaldehyde self-test box.
The formaldehyde self-test box can be made by itself, which is easy to understand and easy to operate. However, when using formaldehyde self-test box to detect indoor formaldehyde content, temperature, humidity and wind speed have great influence on the detection results, which is easy to cause large errors. In addition, the quality of formaldehyde self-inspection products in the market is uneven, and the test results can only be used as a reference.
2. Self-perception method.
Judge your self-awareness according to your feelings. For example, after moving into a new home, the whole family has a cold, the collective immunity is reduced, dizziness, energy loss, fatigue and fatigue, or obvious irritating smell and eye discomfort. When tearing, you may wish to keep indoor ventilation and conduct professional formaldehyde testing as soon as possible.
3. The reaction of animals and plants.
The observation of animal and plant reactions can also detect formaldehyde to a certain extent, such as the withering and death of plants, which happened when they first moved into a new home. Pets are sick, don't eat, have low resistance and low vitality. They always like quiet. If this happens, it is almost certain that your new home will be in trouble.
4. Professional testing institutions.
But if you don't care about or understand the above methods at all, you can go to a third-party testing company, and they will issue relevant testing data. The detection of formaldehyde mostly adopts physical and chemical methods, which is the most complicated method and is also used by third-party testing companies, and most people will not use it.
The detection methods mainly include AHMT spectrophotometry, phenol reagent spectrophotometry, gas chromatography electrochemical method and sensor method.
How harmful is formaldehyde to human body?
To sum up, there are three serious hazards of formaldehyde exceeding the standard:
1. Sensitization: Direct exposure to formaldehyde can cause allergic dermatitis, pigmentation and necrosis, and inhalation of high concentration formaldehyde can induce bronchial asthma.
2。 Irritation: The main harm of formaldehyde is the irritation to skin and mucous membrane. Formaldehyde is a toxic substance in plasma, which can combine with protein. When inhaled in high concentration, it will cause severe irritation and edema of respiratory tract, eye irritation and headache.
3. Mutagenesis: High concentration of formaldehyde is also a genotoxic substance. High concentration of experimental animals in the laboratory can cause nasopharyngeal tumors.
