    病源。。。

    这下挂了。。。
     
    研究表明:甲醛具有强烈的致癌和促癌作用。大量文献记载,甲醛对人体健康的影响主要表现在嗅觉异常、刺激、过敏、肺功能异常、肝功能异常和免疫功能异常等方面。

    其浓度在每立方米空气中达到0.06 -0.07 mg/ m3时,儿童就会发生轻微气喘。当室内空气中甲醛含量为0.1 mg/m3时,就有异味和不适感;达到0.5 mg/m3时,可刺激眼睛,引起流泪;达到0.6 mg/m3,可引起咽喉不适或疼痛。浓度更高时,可引起恶心呕吐,咳嗽胸闷,气喘甚至肺水肿;达到30 mg/m3时,会立即致人死亡。

    长期接触低剂量甲醛可引起慢性呼吸道疾病,引起鼻咽癌、结肠癌、脑瘤、月经紊乱、细胞核的基因突变,DNA单链内交连和DNA与蛋白质交连及抑制DNA损伤的修复、妊娠综合症、引起新生儿染色体异常、白血病,引起青少年记忆力和智力下降。

    在所有接触者中,儿童和孕妇对甲醛尤为敏感,危害也就更大。是装修和家具的主要污染物。其释放期长达3—15年,遇热遇潮就会从材料深层挥发出来,严重污染环境,已成为难以解决的世界性难题。对老人、小孩和孕妇危害最大。

    危害:轻者有鼻、咽、喉部不适和烧灼感、流涕、咽疼、咳嗽等,重者有胸部紧逼感,呼吸困难、头痛、心烦等,长期过量吸入甲醛可引发鼻咽癌、喉癌等多种严重疾病。

    如果确定有毒,又没有窗户或其他解决措施,是不是应该考虑离开呢。

    要长期吸入才致癌的,对于血液系统的影响儿童比较大,成年人应该还可以。不过办公室的封闭环境是比较麻烦,准备一些植物吧,现在你们公司怎么处理这件事情呢?总得弄点空气净化设备什么的吸一吸吧,不然怎么呆人啊。
