What are the hazards of formaldehyde?
1. Sensitization: Direct skin contact with formaldehyde can cause allergic dermatitis, pigmentation and necrosis, and inhalation of high concentration formaldehyde can induce bronchial asthma.
2. Stimulation: The main harm of formaldehyde is the stimulation to skin and mucosa. Formaldehyde is a toxic substance in protoplasm, which can combine with protein. When inhaled in high concentration, severe respiratory irritation and edema, eye irritation and headache may occur.
3. Mutagenesis: High concentration of formaldehyde is still a genotoxic substance. Experimental animals can cause nasopharyngeal tumors under the condition of high concentration inhalation in laboratory.
What are the main manifestations of formaldehyde poisoning?
1. Every morning, I feel depressed, nauseous and even dizzy.
2. People often catch a cold at home; And it is not easy to get better;
3. Although I don't smoke, I often have an uncomfortable throat, a foreign body sensation, and poor breathing;
4. Children at home often cough and sneeze, and their immunity decreases;
5, family members often have allergies and other problems, and they are mass-produced;
6. Family member * * * got sick, and after leaving this environment, the symptoms have obviously changed and improved;
7. Newly-married couples are infertile for a long time and can't find out the reason;
8. Pregnant women find fetal malformation in normal pregnancy;
9. In a newly moved or renovated house, indoor plants are not easy to survive, and leaves are easy to yellow and wither;
10, after the new trick, domestic cats, dogs and even tropical fish died inexplicably;
1 1, I feel sore throat and dry respiratory tract when I go to work, so I will be fine after work;
12. Newly renovated homes and offices or newly bought people have a pungent and irritating smell, and the smell lasts for a long time.
How to remove formaldehyde
1, activated carbon adsorption method to eliminate the harm of formaldehyde
Activated carbon is an internationally recognized expert on drug abuse. Activated carbon masks and gas masks are made of activated carbon. The product uses the physical function of activated carbon to deodorize and detoxify; No chemical additives, no influence on human body. Put two or three dishes in each room, and 72 can basically eliminate indoor odor. This method can be used for medium and low pollution, and can also be combined with other chemical methods, and the comprehensive treatment effect is better.
2, ventilation method to remove the harm of formaldehyde
Through the circulation of indoor air, the content of harmful substances in indoor air can be reduced, thus reducing the harm of such substances to human body. People often close doors and windows in winter, so the indoor and outdoor air can't circulate. Not only the content of formaldehyde in indoor air will increase, but also radon gas will accumulate continuously, even reaching a very high concentration.
3, soil recruit to remove formaldehyde hazards
300 grams of black tea is soaked in two basins of hot tea, put it indoors, and open the window for ventilation. Within 48 hours, the indoor formaldehyde content decreased by more than 90%, and the pungent smell was basically eliminated.
4, plant deodorization method to eliminate the harm of formaldehyde.
Plant decontamination can be selected for medium and low pollution: generally, indoor environmental pollution is light and moderate, and the pollution value is less than 3 times of the national standard. Using plants to decontaminate can achieve better results.
Choose and place plants according to different functions and areas of the room. Generally speaking, it is more appropriate to put two pots of plants with a height of 10 square meter in a room with a height of10 meter.
5, chemical methods to remove the harm of formaldehyde.
(1) Spray and other drugs are easy to cause secondary pollution, which may damage furniture, while activated carbon is physically adsorbed, which is safe and harmless to human body and has mildew-proof and anti-corrosion effects on furniture.
(2) advocate one-time removal (experts doubt it, which is not credible). The release of toxic gases at home is a slow process, so if it is removed today, it will smell again in a few days, and the price is not low.
(3) The products are too miscellaneous and unclear. Although many products for treating formaldehyde are in use? High technology? 、? Environmental protection? Wait, but some inferior chemical synthetic substances were used. Although these products can eliminate formaldehyde to a certain extent, they may also produce other pollutants again, leading to secondary pollution.
6, photocatalyst decomposition method
Stimulated by light, the catalyst in photocatalyst generates negative ions and hydroxyl radicals with oxygen and moisture in the air, which can oxidize and decompose various organic pollutants and inorganic pollutants, and finally degrade them into harmless substances such as carbon dioxide, water and corresponding acids, thus achieving the functions of decomposing pollutants and purifying the air.
Therefore, consumers must be vigilant when purchasing formaldehyde control products. For example, chemical air treatment products are obtained by artificial synthesis, many of which are aromatic compounds. Almost all aromatic compounds contain benzene ring compounds that have been proved or suspected to be carcinogens. In addition, many chemical products are oxidizing and corrosive, which are easy to damage utensils, as well as operators and residents. When the coating is aging and the weather is hot and humid, the coating is easy to be damaged, and harmful substances such as formaldehyde are released, which becomes a hidden danger for families? Timing? Bomb.
The above is the information about formaldehyde that I introduced to you. Formaldehyde is the bane of new house decoration, and it is also the reason why we can't move in after new house decoration. I hope my summary can help you.
