With the improvement of living standards, people are paying more attention to air pollution in newly decorated homes. In response to recent measurements of indoor air pollution in some decorated rooms, the Liaoning Provincial Environmental Monitoring Center reminded residents yesterday: Rooms should be ventilated for at least 2 to 3 months after decoration before moving in, and only after passing a qualified inspection.
Rooms with pollutants exceeding three times the standard must not be inhabited. The provincial environmental monitoring center station recently monitored indoor air pollution in 90 decorated rooms and found that formaldehyde and benzene compounds are the main common pollutants in indoor air pollution, due to differences in the use of decorative materials, the degree of pollution varies greatly among different rooms. However, it was found that rooms with shorter ventilation periods have higher rates of pollutant overruns and more items exceeding the standard, while rooms with longer ventilation periods have relatively milder pollution. For the same room, if tested before basic ventilation and after two months of ventilation, formaldehyde content can decrease by 60%.
Relevant officials from the provincial environmental monitoring center station remind citizens that the national indoor air quality standard requires formaldehyde content to be less than or equal to 0.1 milligrams per cubic meter. If the content is found to exceed the national standard by three times during decoration testing, immediate move-in must be avoided. This is because domestic medical experts have found that decoration air pollution has a greater impact on children with weaker immunity and resistance, and benzene and formaldehyde may trigger childhood leukemia.
Given the limited environmental capacity, simple decoration is advocated. Experts from the provincial environmental monitoring center suggest that when choosing indoor decorative materials, residents should try to select high-quality health and environmental protection building materials that meet national standards. They should pay attention to whether product labels are complete and whether there is a product qualification certificate, and check whether the formaldehyde release amount in the product inspection report meets the national standard requirements.
It is understood that there is an "environmental capacity" issue with residential space. Even if all eco-friendly building materials are used, excessive usage can make it difficult for chemical agents to quickly evaporate, leading to cumulative pollution. Therefore, it is recommended that decoration should be as simple as possible, especially reducing the use of fine woodworking boards and density boards. Additionally, one should consider the pollution from purchasing furniture in advance, as harmful gases from furniture can also cause air pollution.
It is important to choose three types of materials well: stone and tiles, which need attention to their radioactive pollution, especially some natural stones like granite, which should be selected according to national standard regulations; secondly, adhesives and coatings, which are the main source of benzene pollution in indoor air, and care should be taken not to buy counterfeit products; thirdly, artificial boards, which are the main source of indoor formaldehyde pollution. Besides paying attention to brands and external quality, it is best to use formaldehyde removers to handle harmful substances in the boards before decorating.
"The residents should choose reputable decoration companies to avoid the substitution of inferior materials," said the provincial environmental monitoring expert. Currently, most homeowners focus on the purchase of main materials, while auxiliary materials are often purchased by the decoration company itself. Some decoration companies may buy cheaper auxiliary materials, resulting in formaldehyde exceeding standards and being difficult to remove, especially formaldehyde sealed in wall latex.
Moreover, it's not advisable to rush moving in after decoration. Windows should be opened to allow indoor polluted air to diffuse and circulate, as ventilation is a simple and feasible way to improve indoor air quality. Generally speaking, several months after decoration, indoor air can reach the standard. Before moving in, if any strange smell is detected, it is suggested to invite a monitoring department for indoor environmental testing. Currently, the cost of formaldehyde content detection for a regular point by official monitoring departments is approximately 200 yuan (rooms smaller than 50 square meters require 1 to 3 points).
It is revealed that current methods for indoor air treatment include activated carbon, bamboo charcoal, photocatalysis, negative ions, etc., and the simplest method is to grow some flowers and plants indoors, such as Aloe Vera and spider plants that can absorb formaldehyde, chrysanthemums, ivy, and Cycas revoluta that can absorb benzene compounds.
