济南除甲醛：世界卫生组织日前发布了《室内空气质量指南》,该《指南》指出,室内空气的污染源主要来自四个方面,即建筑材料、家电、取暖设备和做饭时产生的烟尘等.室内空气中的化学污染物主要有苯、一氧化碳、甲醛、二氧化氮、氡等九种物质.其中,苯位列第一,这种物质广泛存在于建筑材料中,尤其是油漆,可致癌;排在第二位的是一氧化碳,其安全标准是24小时内每立方米空气中不超过7毫克;排第三的是甲醛,安全标准是每立方米空气中含量低于0.1毫克,超量会伤害肺功能.
Formaldehyde removal in Jinan: The World Health Organization recently issued the Guidelines for Indoor Air Quality, which pointed out that indoor air pollution mainly comes from four aspects, namely, building materials, household appliances, heating equipment and smoke and dust generated during cooking. The main chemical pollutants in indoor air are benzene, carbon monoxide, formaldehyde and 2. Nitric oxide, radon and other nine substances. Among them, benzene ranks first, this substance widely exists in building materials, especially paint, can cause cancer; carbon monoxide ranks second, its safety standard is not more than 7 mg per cubic meter of air within 24 hours; formaldehyde ranks third, the safety standard is less than 0.1 per cubic meter of air. In milligrams, excess can damage lung function.
点评:尽管这些污染物在建材产品中的含量都有一定标准,但家庭装修后这些材料集中释放污染物,室内空气必然受到影响.我们还是建议,新装修的居室不要马上入住,尽量在半年后入住.家庭装修尽量选择有环保标志的产品,在家具选择方面,人造板材中甲醛含量比较多,最好选用木板材料密封程度较高的家具;新买的家具放一段时间再用;使用人造板材的衣柜时,尽量不放内衣和孩子的衣服;冬天每天要开窗,一天不少于两次,每次不少于30分钟,以免污染加重;还应注意调节空气湿度.http://www.jntkzl.com
Comment: Although the content of these pollutants in building materials has certain standards, the indoor air will be affected by the concentration of pollutants released by these materials after home decoration. We still suggest that the newly decorated rooms should not be occupied immediately, try to stay in half a year later. Family decoration should try to choose products with environmental protection marks and furniture selection. In terms of choice, the formaldehyde content in wood-based panels is relatively high, it is better to choose furniture with high sealing degree of wood-based materials; newly bought furniture should be put for a period of time to reuse; when using the wardrobe of wood-based panels, try not to put underwear and children's clothes; in winter, windows should be opened not less than twice a day, no less than 30 minutes each time, in order to avoid aggravating pollution; Attention should be paid to regulating air humidity.http://www.jntkzl.com
