装修产生的有害气体来自哪里？

装修产生的有害气体来自哪里？

1.有害气体-氨
氨是种具有较强刺激性气味的有害气体，对人体危害很大，对皮肤组织具有腐蚀作用，并且能够吸收人体组织中的水份，使蛋白质变性，破坏细胞膜结构等。氨释放比较快，不会在空气中长时间积存。氨主要来源于混凝土中的防冻剂和室内部分装修材料，如有一些家具涂料使用的增白剂与添加剂中包含氨。
2.有害气体-氡
氡是由镭衰变产生的天然放射性惰性气体，无色无味，在常温下，氡和氡衰变产物氡子体在空气中形成放射性气溶胶，易被呼吸系统截留，经累积后易引发肺癌。此外，氡与人体脂肪有很强的亲和力，尤其是氡进入神经系统后，危害更大。氡主要来源于建筑材料，如花岗岩类的装修材料，水泥，石膏等，包含放射性物质比较多的石材更容易释放出氡。
3.有害气体-甲醛
甲醛是一个没有颜色也非常容易溶于水的刺激性气体，它的水溶液就是福尔马林，当室内甲醛的浓度超过30mg/米的时候，就有可能会造成死亡。甲醛这种有害物质能够使得蛋白质变性，有致畸作用，出现致癌的不良反应，而且对神经系统，免疫系统，肝脏等都有毒害作用。

甲醛是装修污染最为常见，最严重的污染物。甲醛主要来源于装修材料，如墙布，墙纸，化纤地毯，油漆，涂料等，在遇热和遇潮的情况下，渐渐释放引起室内污染。
4.有害气体-苯
苯，甲苯和二甲苯均属于同系物，当前室内的装饰材料多用甲苯，二甲苯替代纯苯来制作各类胶，油漆，及涂料及防水材料的溶剂和稀释剂。长时间吸入苯，可造成过敏性皮疹，皮炎等，也有可能造成再生障碍性贫血，月经异常，胎儿畸形，中枢神经系统障碍和发育迟缓等。苯已被世卫确定为强致癌物质。苯的主要来源亦是装饰材料，苯及其同系物是油漆制造中不能缺少的溶剂的重要成份，亦是涂料添加剂的主要成份。

你好，
装修用到的材料都会释放甲醛苯等有害气体，家具也会，原因是现在的材料很多都是经过化学处理，比如防腐，防锈，防水，防磨等，所以新材料和家具都会有一个释放期，一般为两年
装修后要做好甲醛等气体治理，治理方法如下：
1.保持室内通风三个月以上
2.在家中放些纳诺洁天然纳米硅，去味除甲醛效果都比活性炭强5倍，一个月左右就可以了，某宝上有
3.在家中种些吊兰，芦荟，龙舌草等植物，对去甲醛也有一定的效果
以上方法可以同时使用，互不干扰，效果可叠加
希望我的回答对您有所帮助！

1、来自于做室内装饰的胶合板、细木工板、中密度纤维板、刨花板等人造板材。因为人造板粘合剂(脲醛树脂)含有大量甲醛的成分，甲醛不但有助提高粘合性，还有加强板材的硬度及防虫、防腐的功能，因此被广泛应用。对于现在市面上的人造板甲醛含量为0等说法，人们不可盲目的相信，其实只是将做好的人造板放置一段时间让其挥发，使甲醛含量降低到一定的低量而已，而能做到这种程度的工厂很少。
2、来自于人造板材制造的家具。有的家具生产厂家为了追求利润，使用不合格的板材，以及制造工艺不规范，使家具成了甲醛的排放站。在一项比较试验结果中显示：在所抽取的60套中密度家具样板中，有29套甲醛超过了国家有关标准，不达标高达48.23％。其中的甲醛挥发周期可持续3-5年。
3、来自于含有甲醛成分的其他各类型装饰材料，比如白乳胶、泡沫塑料、油漆和涂料等。北京市工商局2004年8月发布了建筑装饰材料质量监督抽查结果，并将56种不合格建材商品全部清出北京市场。水基型胶粘合剂中的甲醛超标问题，查处7种乳胶胶粘剂中的问题全部是游离甲醛超标。其中白乳胶有的胶粘合剂标称不含甲醛，而实际甲醛含量超标近5倍。
4、来自于室内装饰纺织品，包括床上及用品，墙布，墙纸，化纤地毯，窗帘和布艺家具。在纺织生产中，为了增加抗皱性能，防水性能，防火性能常加入一些含有甲醛助剂，在使用时会释放出甲醛。为了减少甲醛对人们的伤害，国家有关部门在对直接接触皮肤的床上用品和室内(包括车，船，飞机)用品，如沙发，床罩等甲醛含量进行了严格控制。
