Formaldehyde is a common indoor air pollutant found in virtually all homes and buildings. It is a colorless gas with a pungent odor, and at elevated levels is highly irritating to the eyes, nose, and lungs. Since 2004, formaldehyde has been recognized as a known human carcinogen by the International Agency for Research on Cancer (IARC). In 2011, the National Toxicology Program (NTP) within the U.S. Department of Health and Human Services (DHHS), in their Twelfth Report on Carcinogens, also classified formaldehyde as a known human carcinogen. Formaldehyde is released into the home from many indoor sources, including plywood, particleboard, and other pressed wood products used in home construction and furnishings, and many consumer products. 

 

 

甲醛可以说是影响家庭生活环境中最有害的一种气体了。甲醛超标是很多家庭都非常头疼的一个问题,甲醛超标的危害有哪些呢?甲醛超标主要是家具、油漆等中所含的甲醛超标,甲醛超标怎么办?哪些方法可以除甲醛呢?
归纳起来,甲醛超标主要有三点严重危害:
1. 致敏作用:皮肤直接接触甲醛可引起过敏性皮炎、色斑、坏死,吸入高浓度甲醛时可诱发支气管哮喘。
2. 刺激作用 :甲醛的主要危害表现为对皮肤粘膜的刺激作用,甲醛是原浆毒物质,能与蛋白质结合、高浓度吸入时出现呼吸道严重的刺激和水肿、眼刺激、头痛。
3. 致突变作用:高浓度甲醛还是一种基因毒性物质。实验动物在实验室高浓度吸入的情况下,可引起鼻咽肿瘤。
甲醛检测和治理:新装修的房屋和新购买的家具,或当感觉室内空气质量不好时,进行检测;装修后不宜立即入住,应开窗、通风让室内污染空气散发;若室内环境中甲醛已超标应及时进行治理。目前甲醛治理产品主要有:空气净化器,对室内甲醛等污染物质有一定吸附作用;可对室内甲醛等有害气体进行催化分解;利用植物进行净化,吊兰、芦荟、龙舌兰等可降低室内甲醛的浓度。
