Ms. Zhang, who lives in Qingpu District, said that her child was in the first grade in September this year. In order to facilitate her children to go to school, she bought a house near the school. She just renovated it in early August. She is worried that formaldehyde and other toxic substances will appear in the new house. In case of exceeding the standard, I want to know how to remove indoor pollution quickly and effectively?
In this regard, the staff of the Municipal Quality Inspection Institute said that there are five "invisible killers" in home decoration pollution, formaldehyde, benzene, ammonia, hydrazine and total volatile organic compounds. Among them, formaldehyde is derived from plate materials, such as wood-based panels, sandwich panels and adhesives; benzene is mainly from paints, paints, glues, wallpapers, carpets, synthetic fibers, detergents, solvents, etc.; ammonia is mainly from concrete additives and Interior decoration materials; enamel hiding in granite and ceramic products such as tiles and sanitary ware; total volatile organic compounds are derived from furniture, wallpaper, etc.
The staff said that indoor formaldehyde pollution has become the main cause of high incidence of childhood leukemia. "Formaldehyde is a type of carcinogen determined by the World Health Organization. It harms the human eye and the upper respiratory tract mucosa. The mild poisoning reaction is conjunctival congestion, redness, difficulty in breathing, heavy breathing, hoarse throat, etc.; Cough, headache, dizziness, nausea and vomiting, memory loss and other symptoms."
How to identify the newly renovated new home pollution? The staff said that professional testing agencies can be invited to identify. At present, the municipal quality inspection office provides indoor formaldehyde concentration testing.
In addition, the staff also introduced that the air quality in the home can be judged to some extent through the human body's feelings: "If you feel upset, nausea, dizziness, poor breathing after getting up every morning, the symptoms will obviously improve when you change the environment. It shows that your family's indoor pollution has exceeded the standard; if the family is very susceptible to colds, especially the elderly and children are prone to illness, it is likely that the indoor pollution is excessive; or the plants in the home are not easy to survive, even the plants with strong vitality are easy. The phenomenon of yellowing and wilting of the leaves may also result in excessive indoor pollution."
In order to prevent indoor pollution from exceeding the standard, the best way is to eliminate the source of pollution from the source. “First of all, when choosing decoration, try to choose the board with less glue, use less furniture made of plywood, choose more solid wood board furniture; secondly, streamline the decoration, use less paint, adhesive, decoration, despite the materials used. They are all qualified, but over-renovation will cause pollution to overlap with each other, and the total pollutants will be released above normal. Third, when selecting healthy materials, when selecting materials, not only should we pay attention to the environmental protection of the main materials, but also Focus on the selection of accessories."
For a family that has been renovated like Ms. Zhang, it is necessary to continue to open the window and ventilate, and conditionally buy some plants with adsorption to be placed indoors. “A newly renovated home should pay attention to window ventilation. The longer the ventilation time, the higher the indoor air quality; the home can put some green plants with the function of purifying air, such as ivy, iron tree can absorb benzene and organic matter, spider plant And aloe vera can absorb formaldehyde..."
