According to an investigation by the China Indoor Environmental Monitoring Work Committee, 60% of newly decorated classrooms in schools exceed the standard formaldehyde; the Chinese Center for Disease Control also announced that more than 65% of households have reached the standard formaldehyde, and the winter formaldehyde exceeding rate reached 73%.
In the past two years, reports of diseases caused by excessive formaldehyde after house decoration have been reported frequently in the newspapers. Many people have become discolored by the "formaldehyde" and always feel that their houses are polluted. A Mr. Wang who has just moved into a new house told reporters: "My house has just been renovated and new furniture has been added, but I always feel uneasy living and want to spend money to check it out. After all, tens of thousands of dollars have been spent on decoration. I don’t care about the hundreds of dollars in testing costs."
Actually, there are many consumers who hold Mr. Wang’s ideas. It is understood that in the first half of this year, the Beijing Consumers Association received a total of 594 complaints about indoor furniture pollution, an increase of 10% over the same period last year. my country has held three national conferences on indoor air pollution prevention and control this year alone, and the "building syndrome" caused by indoor air pollution has attracted widespread attention in society.
In this regard, Song Guangsheng, director of the Environmental Testing Center of the China Interior Decoration Association, said that decoration pollution, construction pollution and furniture pollution are the three major sources of indoor air pollution. Among them, low-quality building materials, furniture and decoration materials are the main sources of pollution, such as non-environmental paints, coatings, and synthetic fiberboards.
Zhang Qi of the Environmental Protection Committee of the Beijing Building Decoration Association believes that in addition to some manufacturers and decoration companies using building materials with excessive hazardous substances in order to reduce costs, the current national standard "Limits for Release of Hazardous Substances in Wooden Furniture" also has some loopholes: The formaldehyde test is only for man-made panels, not the finished furniture used by consumers, and the test sample area is too small, only 0.075 square meters; second, only the heavy metal content in the paint is regulated, and the harmfulness in the adhesive is ignored The release of substances pollutes.
Although formaldehyde has brought many inconveniences to people's lives, when talking about people's panic about formaldehyde, Song Guangsheng still thinks that it is unnecessary. He said that in rooms newly decorated or purchased with new furniture, in addition to taking precautions against the elderly, children, pregnant women and the frail people, as long as the following points are done, the harm of air pollution to the human body can be controlled. lowest.
First of all, follow the principle of simple decoration, and try not to make ceilings, wall skirts, and heating covers.
Second, do not spread the same floor material in each room. It should be solid wood flooring, composite flooring, ceramic tiles, etc.; when decorating, some products that purify and eliminate pollution can be used, and they should be directly on the large core board or other composite materials. Use: When using artificial boards, paint should be applied to the saw cut to make it fully cured to prevent formaldehyde emission; water-based paint is best.
Third, the number of furniture should not be too much when arranging the room, especially the children’s room or bedroom with a relatively small room area. Too much furniture can easily exceed the carrying capacity of harmful substances in the unit space; Check whether the filling is made of small pieces of adhesive.
Finally, in winter, due to the high room temperature and low ventilation, the pollutants in the air will increase than usual. Therefore, the windows should be opened every morning for no less than 15 minutes and more outdoor exercise should be done.
