The air is not circulating, and the indoor air may be higher than that of outdoors! Detailed explanation of the 7 major sources of pollutants

Outdoor air pollution makes people feel sick of absorbing substances that are harmful to health, but is it safe to stay indoors? Experts say that if indoor air is not well circulated, the concentration of pollutants is often higher than that of the outside. Building materials, furniture, electronic equipment, and even dry laundry, cleaning supplies at home will produce explosive organic substances, beware that these indoor air is poisoning the body and causing chronic inflammation.

Zhang Kairen, professor of the Department of Public Health at Taipei Medical University, said that people are worried that PM2.5 outside of home may cause cancer and think it is safer to stay at home. But there are many harmful substances in life that people are prone to ignore, such as building materials containing formaldehyde, bacteria in damp bathrooms, and wall cancer in old houses. If the indoor air quality is not good, it will increase the risk of disease.

Formaldehyde, which is highly related to carcinogenic risks, is most commonly found in synthetic wood boards, paints, wallpapers, and adhesives, and is widely used in daily necessities. According to Brahma, formaldehyde is colorless, but it smells pungent. As long as there is 0.1ppm of formaldehyde in the air, it can smell strange. However, higher than 0.5ppm, it will irritate the eyes and throat. Continuous inhalation will cause symptoms such as nausea, vomiting, coughing, asthma, etc. To eliminate formaldehyde, in addition to maintaining wind, some plants can be potted to increase oxygen and purify the air.

2. Home electronic equipment

Countermeasure: Place it in the corner of the home and keep a certain distance from the living space. You can turn on the air purifier in the living room, or place green potted plants next to the appliance.

Including TVs, computers, refrigerators, printers, etc., all may release chemical substances, especially the shells of electrical appliance products. Some heat-resistant plates will release brominated diphenyl ether. This is a toxic powder. Although it is small in quantity, it is a kind of environmental hormone, which can easily increase the chance of infertility and lead to premature birth in pregnant women. Printers may also suck out super-fine carbon particles, affecting the respiratory tract, or produce ozone, which can also damage the lungs.

3. Chemical substances on dry laundry

Countermeasures: Take off the plastic bag and put it in the ventilation room for a period of time, and then put it in the cabinet.

It is convenient to dry coats and coats, but when you retrieve the clothes, you will sometimes hear a special smell on the clothes because the chemical substances in the dry cleaning solvent have not yet been released. Dry cleaning agents are mainly divided into tetrachloroethylene and petroleum. Tetrachloroethylene causes liver damage. Long-term inhalation of petroleum can cause chronic obstructive respiratory diseases, which is extremely harmful. Zhuang Kairen suggested that after taking the dry-washed clothes home, they should be taken out from a plastic bag, placed in the winding room for a period of time and then put them in the cabinet.

Solution for cleaning products: Avoid using in closed spaces.

Cleaning agents, disinfectants, hair gels, paints, sucking agents, etc. are all sources of indoor active organic pollutants. Some cleaning products also add fragrances. For people with sensitive smells, they will make people feel headache after hearing them for a long time. The organic solvents added to various cleaning products may contain formaldehyde and benzene, which will cause damage if you want to clean the environment. Zhuang Kairen reminds that when using proactive organic matter, you must avoid exceeding a certain concentration in the closed space, which will increase the risk of cardiovascular disease and cancer.

5. Bio-pollutants in damp space

Countermeasures: Use an electric fan and dehumidifier to strengthen the indoor drying.

Old houses or bathrooms without external windows are prone to bacterial growth, and small spores spread in the air, which can cause health hazards to people, causing allergic reactions such as asthma, nasal congestion, runny nose, sneezing, etc. Zhuang Kairen suggests that under the restriction of space that cannot be changed, the fan can be turned on to blow, or the cooling air can be turned on to increase the indoor circulation, or the dehumidifier can be used to strengthen the indoor drying.

6. Pet hair and cat sand

Countermeasures: help shave pets in summer and carefully select cat sand materials.

In addition to formaldehyde, proactive organic pollutants, bacteria, etc., the hair of pets needs special attention, especially in the hair dregs, small and dirty veins that are invisible to the naked eye, which affects the respiratory tract and may also cause allergies. Brahma Ren said that to prevent pet hair from flying, dogs should be shaved in summer; cat sand should also be selected, as mineral powder can easily increase the burden on the respiratory system.

7. Other indoor air

solutions: Choose plastic materials that meet the testing and do not buy cheap products.

Plastic toys, yoga pavilions, etc., if you use inferior plastic materials, you will also have air pollution problems. Before choosing, it is best to see whether it meets environmentally friendly materials, have passed inspections, etc. If you want to save money, choose low-priced products and be careful to poison your body.
