| 比较常见的污染物：甲醛和氡气。 Here are two common pollutants: formaldehyde and radon. 在居家的天花板、墙壁贴面使用的塑料、隔热材料及塑料家具中一般都含有甲醛，它除具有较强的粘合性能外，还具有加强板材的硬度及防虫、防腐的功能。甲醛是一种无色易溶的刺激性气体，当室内含量为 0.1 毫克/立方米时就有异味和不适保定平面设计培训 防撞墙模具 防撞墙模具 防撞护栏模具 大棚遮阳网 遮阴网感；0.5 毫克/立方米可刺激眼睛引起流泪；O.6 毫克/立方米时引起咽喉不适或疼痛；浓度再高可引起恶心、呕吐、咳嗽、胸闷、气喘甚至肺气肿；30 毫克/立方米时可当即导致死亡。长期接触低剂量甲醛还可引起慢性呼吸道疾病、女性月经紊乱、妊娠综合症，引起新生儿体质降低、染色体异常，甚至引起鼻咽癌。控制室内甲醛污染，行之有效的办法是加强室内通风换气，经常性地打开窗户通风，甲醛浓度就会迅速降低。 Formaldehyde is generally contained in the ceiling and wall facing plastics, thermal insulation materials and plastic furniture at home. In addition to its strong adhesion, it also has the functions of strengthening the hardness of the board, insect prevention and corrosion protection. Formaldehyde is a colorless and soluble irritant gas. When the indoor content is 0.1mg/m3, it has peculiar smell and discomfort; 0.5mg/m3 can stimulate eyes to cause tears; 0.6mg/m3 can cause throat discomfort or pain; if the concentration is higher, it can cause nausea, vomiting, cough, chest tightness, asthma or even emphysema; 30mg / M3 can immediately lead to death. Long term exposure to low-dose formaldehyde can also cause chronic respiratory diseases, menstrual disorders in women, pregnancy syndrome, neonatal physical decline, chromosomal abnormalities, and even nasopharyngeal carcinoma.
