It's worrying that the formaldehyde in the house has exceeded the standard in 7 years of decoration, and the children at home suffer from leukaemia! For days, pan Yinghui, a 5-year-old girl from dingjiao village, Baoyan Town, Dantu District, Zhenjiang City, Jiangsu Province, has been influencing the hearts of many netizens -- in May, she was found suffering from acute lymphocytic leukemia in the middle class of Baoyan central kindergarten.
On the morning of August 3, there was a news that surprised pan Yinghui's family & hellip; & hellip;
Testing site
The reporter of Modern Express learned that recently, upon the application of Pan Yinghui's family, a professional testing center in Jiangsu Province tested her bedroom, and the results showed that the formaldehyde in the house which had been decorated for more than 7 years exceeded the standard: the formaldehyde content in the room where pan Yinghui lived and the room where other family members lived reached 0.117mg/m & sup3; and 0.109mg/m & sup3; respectively, while the national standard was less than or equal to 0.10mg/m &Sup3;, which means that the formaldehyde content in both rooms tested exceeds the standard.
His daughter-in-law's first child was miscarried due to deformity, and the second child was only 5 years old and suffered from leukemia. Lao pan suspected that there were harmful substances in the room, so he invited a professional testing agency to test it at home.
According to the instructions of the professionals, pan closed the doors and windows of the room where the children slept for more than 12 hours, and the other rooms remained open. The formaldehyde content in children's sleeping room was 0.117mg/m & sup3; and that in other open rooms was 0.109mg/m & sup3;,
They all exceed the national standard.
Pang said painfully that this was equivalent to a family inhaling excessive formaldehyde in the room for seven years.
What is the main source of formaldehyde
The fibreboard in the furniture is mostly hot pressed with urea formaldehyde resin, which will release formaldehyde, especially for the newly decorated family. The formaldehyde release may last for a warm or even several years. At the same time, we are reminded that the winter is a period of high formaldehyde incidence. When the house is hot in winter, a large amount of formaldehyde will be emitted. Solid wood furniture, wood in storage, in order to prevent corrosion, may spray formaldehyde. For example, formaldehyde may also be found in the newly purchased clothes and fabrics in our life, because in order to prevent wrinkles and make dyes better colored, some formaldehyde containing additives will be used and will also be released. In addition, formaldehyde will be used in coated wallpaper.
Artificial board: plywood, MDF, creative board for wood floor or furniture.
Accessories for decoration: auxiliary materials used in decoration, such as adhesives, preservatives, foams, thermal insulation materials, etc.
Paint wallpaper: wall covering, wallpaper, paint and coating used for wall decoration.
Textile category: chemical fiber carpet, iron free shirt, printed fabric.
Daily necessities: cosmetics, detergents, insecticides, disinfectants, printing ink, paper, etc.
Tail gas smoke: tobacco smoke, tail gas, haze, etc.
General solutions for indoor formaldehyde exceeding standard
1. The decorated house should keep ventilation at all times, a month is a cycle, and keep ventilation and convection, because the clean indoor and outdoor wind will bring the formaldehyde released by the indoor home out of the room, which can effectively reduce the concentration of indoor formaldehyde and other pollutants.
2. Place some activated carbon solids in some corners of the house or on the furniture. These solids have good adsorption, which can effectively absorb formaldehyde and other harmful substances in the air. This way is also more economical.
3. Cultivate more plants at home. Plants have the function of purifying the air. Plants such as Chlorophytum, green pineapple and ivy are good at absorbing formaldehyde. However, the adsorption capacity of plants is relatively limited, so they can only play an auxiliary role.
4. The photocatalyst can decompose the formaldehyde in the air into harmless substances through the action of light. However, the required period is relatively long and the effect is not obvious.
