Ms. Hu intended to purchase a large house for her second baby. The two old people came to Changsha from their hometown to celebrate the Chinese New Year. In order to allow the family to enter the spacious new house during the Spring Festival, they let the decoration master hurry to catch up. Finally this year The renovation was completed at the beginning of the month and it was checked in at the end of January. “At the end of January, when it was rain and snow, most of the time, the windows and doors were closed and the air-conditioning was heating.†Ms. Hu found that although there was no noticeable odor in the room, the newly-purchased green plants had begun to yellow and the old people often felt chest tightness. Relatives and friends reminded that the decoration may cause problems in indoor air quality. Ms. Hu originally believed that it was due to considerations of oldness and inferiority. When decorating, attention was paid to the selection of environmentally-friendly materials. This should not be a problem. After everyone's reminder, there was also some concern. So on the first day of the year after work, we called the 96333 hotline to make an appointment for the testing service. I heard that Ms. Hu had finished her stay less than a month after finishing her renovation. Cai Zhen, a senior environmental examiner in the Evening News Service Consortium, had some concerns. The preliminary test data show that indoor formaldehyde pollution exceeds national standards. “A lot of people now know that the haze is terrible. In fact, indoor pollution caused by improper decoration and insufficient ventilation is more traumatic than the outdoor haze.†Cai Zhen said that many new homes detected after the Spring Festival, the indoor air conditions are not too Optimistically, decoration pollutants mainly include formaldehyde, benzene, ammonia, etc., which can have adverse effects on the human respiratory system, nervous system, immunity, and endocrine system. Especially for children in their growing years, indoor air pollution is more harmful to them. Solid wood furniture can not be equal to the environmental protection painting Cai Zhen introduced that, based on some of his usual contacts, the owner's understanding of the new house's air quality mainly has the following three misunderstandings. Some people think that home is bought solid wood furniture, there will be no pollution. In fact, solid wood furniture can not be equal to the environmental protection painting. Although natural wood itself is healthy, the excessive formaldehyde and benzene content of solid wood furniture is mainly due to the fact that the paints and adhesives used do not meet national requirements. Many owners believe that the interiors used in the renovation are environmentally friendly products and the indoor air quality is safe. Cai Zhen said that environmental protection materials are not free of harmful substances, but only in the limited category, if the superimposed pollution of the decoration materials, it may lead to excessive standards. “Simply put, if we use 10 sheets in a limited space and the air quality is up to the standard, we can't guarantee that 20 sheets can be used.†Another misconception is that many owners think that there is no pollution in the house because there is no smell in the house. Cai Zhen introduced that low winter temperatures, relatively low release of harmful gases, people's sense of smell is relatively slow. And not every contaminant has a pungent odor, such as a benzene series that is not perceived by the human sense of smell. Decoration pollution can be prevented and controlled. Appointment inspection recognizes qualifications Although the pollution of home decoration is invisible and invisible, it is preventable and controllable. Cai Zhen introduced that the prevention of indoor air pollution should start from the source, we should try to use environmentally friendly materials, please apply to the formal home improvement company in accordance with environmental protection requirements. Try not to use natural stone in the bedroom, such as marble and granite, which are the main causes of indoor radon pollution. Cai Zhen reminded that the new house should be ventilated for at least 3 months prior to occupancy. Some activated carbon can be used to absorb harmful gases in the furniture. It is best to check in after conducting a professional indoor environment test. Today, a search on the Internet, indoor air quality testing agencies varied. Experts reminded that when selecting a testing organization, we must pay attention to checking whether it has a qualification certificate, and whether it can issue a test report with a national measurement certification CMA stamp. CMA certification means “China Metrology Accreditationâ€. Inspection reports with CMA marks can be used for product quality evaluation, results, and judicial arbitration, and have legal effect.
