1. Radon Radon is a radioactive inert gas, colorless and tasteless. It exists in cement, sand and gravel.
Hazard: Indoor radon pollution is the second cause of lung cancer after smoking.
Second, formaldehyde formaldehyde has a strong smell. Artificial board uses adhesive, which contains formaldehyde.
Hazard: After inhaling high concentration formaldehyde, there will be serious respiratory irritation. Direct skin contact with formaldehyde can cause dermatitis. Regular inhalation of a small amount of formaldehyde can cause chronic poisoning. According to some data, more than half of children with leukemia have the experience of luxury decoration at home.
Benzene is a colorless liquid with a special aromatic smell.
Hazard: Long-term inhalation of benzene can lead to aplastic anemia.
Four. TVOC total volatile organic compounds (TVOC) mainly come from coatings and adhesives.
Hazard: TVOC can cause dizziness, headache, lethargy, weakness, chest tightness and other symptoms.
5. Ammonia gas is very soluble in water, which has a rapid effect on eyes, throat and upper respiratory tract and is highly irritating.
Hazard: Long-term exposure to low concentration ammonia can cause laryngitis, hoarseness and pulmonary edema.
Methods of removing harmful substances:
Put salt water in the new house
Based on the solubility of formaldehyde in water, we can put a few pots of salt water in each room, which can initially absorb a lot of pungent smell in the room.
Indoor ventilation
As we all know, formaldehyde is a volatile substance. We can use this to open the doors and windows of the room and keep the air convection inside and outside the house. This effect will last for about 2 months. However, this method should pay attention to closing the doors and windows at night to avoid being stolen.
Indoor temperature rise
Generally, formaldehyde volatilizes very slowly. If you want it to evaporate as soon as possible, you must find ways to increase the indoor temperature. You can turn on the air conditioner at an appropriate time to increase the indoor temperature and speed up the volatilization of formaldehyde.
Adsorption of activated carbon, etc.
We can use some things with strong odor adsorption function to improve indoor air quality. At present, activated carbon is the most popular in the market. Putting about 50g of activated carbon per square meter can play a good adsorption role on formaldehyde, but at the same time, we should pay attention to the replacement of activated carbon, usually once every 7-8 months. Here, I also listed other things with this formaldehyde adsorption function. You can choose according to your needs: tea, salt water, grapefruit peel, onion slices, pineapple pieces, white vinegar aromatherapy and so on. Coal ash can also remove formaldehyde gas, so you can choose to use it yourself.
green plant
Plant adsorption method is also a good choice. A large number of investigations and studies by scientists show that many green plants, such as chlorophytum, cactus, Brahma, cycad, chrysanthemum, etc., have strong absorption capacity for formaldehyde. These plants can effectively absorb formaldehyde and decorate the room at the same time, which is one of the in addition to formaldehyde methods commonly used in new houses.
