(Reporter Li Yuyang) In recent days, the public, Miss Li, always feels dizzy and discomfort after getting up. She thinks about the report that the formaldehyde in the furniture is harmful to the health of the furniture. She suspects that it was a wardrobe that she just bought three months ago. At work. The people with similar confusion are not only Miss Li, but Ms. Cheng calls the hotline 96333 to say that the formaldehyde in her newly purchased children's furniture is highly volatile.
Complaints, formaldehyde exceeded the standard, disgusting dizziness
Recently, Ms. Cheng spent more than 4,000 yuan to purchase a set of children's furniture, including a bunk bed, a set of small tables and chairs and a computer desk. "At that time, I tried to avoid the impact of the family's poison on the children. I chose the solid wood furniture. I didn't expect it to happen." Ms. Cheng said that after the furniture was bought back, it always had a strong pungent smell, not a week, 6 The old son appeared nausea, dizziness, and then appeared red spots and other symptoms. In this regard, the testing agency experts said that because children's physical sensitivity, the fastest and strongest response to toxic substances, so children's furniture formaldehyde is often easily found.
Experiment, the higher the room temperature, the faster the formaldehyde is released.
Experiments show that when the room temperature is raised to 30 Â° C and the indoor relative humidity is 45%, the formaldehyde emission concentration in the air is 0.223 mg / m 3 , which is 2.23 times higher than the national indoor air quality standard; Â°C, when the relative humidity is 50%, the formaldehyde emission concentration exceeds the standard by 5.53 times; when the room temperature is 18 Â° C, the relative humidity is 30%, the formaldehyde emission concentration in the air is only 0.033 mg / cubic meter, far lower than the country. standard.
According to experts from the Provincial Center for Disease Control and Decorative Materials and Indoor Air Monitoring, summer is the most â€œmanicâ€ season for formaldehyde volatilization. For every 1 Â°C rise in room temperature, formaldehyde volatilized in wooden furniture and flooring will make formaldehyde in indoor air. The concentration increased by 0.15-0.37 times. In this environment, people feel as if they are in a closed room sprayed with insecticide, and they feel stinging and itching.
In addition to formaldehyde, indoor pollutants in summer also have the following three aspects: ammonia pollution caused by the release of concrete antifreeze caused by construction work in winter; biological pollution inside air conditioners, such as "legionella"; indoor environmental odor pollution, In particular, odor pollution caused by chemical products, plastic products, toilets and kitchens is more prominent. Although the above odors may not be harmful to the human body, but after a long time, people may have symptoms such as vomiting, headache, and even induce various chronic diseases.
Reminder to avoid indoor formaldehyde pollution
In order to avoid formaldehyde pollution in summer, you may wish to take the following methods:
Ventilation of the window. Do not rely too much on air conditioning in summer indoor heatstroke, because most household air conditioners can only adjust the room temperature and have no ventilation. In the morning and evening when you are cool, you can open the window to effectively reduce the concentration of indoor pollutants. Especially for families with pregnant women or infants. When you turn on the air conditioner, you can also leave a small slit in the shade.
Place some activated carbon in the source of pollution. The source of pollution is generally the place where the artificial panels such as heating hoods, drawers, wardrobes, bookcases, and bed boxes are used in large quantities. After the activated carbon is placed, the furniture must be closed, and the harmful gases such as formaldehyde released will be adsorbed by the activated carbon to avoid pollution.
Put an aquarium in the room. Contaminants such as formaldehyde are soluble in water, and the aquarium can reduce indoor pollution.
If the concentration of pollutants such as formaldehyde is too high, you can purchase indoor air purifiers for treatment, such as chemical decomposition, molecular sieve filtration, activated carbon adsorption, negative ion catalysis, etc., and some use closed wax to seal the furniture surface to achieve inhibition. The purpose of the release of harmful gases.
