回答1:

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。

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、细胞核的基因突变,DNA单链内交连和DNA与蛋白质交连及按捺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,儿童和妊妇对甲醛尤为敏感,危害也就更大。是装修和家具的主要污染物。其开释期长达3—15年,遇热遇潮就会从材料深层挥发出来,严峻污染环境,已成为难以解决的世界性挫折。对白叟、小孩和妊妇危害最大。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,呼吸难题、头痛、心烦等,长期过量吸入甲醛可引发鼻咽癌、喉癌等多种严峻疾病。

甲醛为较高毒性的物质,在我国有毒化学品优先控制名单上甲醛高居第二位。甲醛已经被世界卫生组织确定为致癌和致畸形物质,是公认的反常反应源,也是潜伏的强致突变物之一。甲醛中毒会对人体造成很大危害。

刺激作用:甲醛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、高浓度吸入时泛起呼吸道严峻的刺激和水肿、眼刺激、头痛。

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。

致突变作用:高浓度甲醛仍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、小儿白血病。孕妇长期吸入高浓度甲醛,会加重胎儿畸形风险。

回答2:

甲醛对孕妇影响:会导致流产、胎儿畸形、宫外孕、弓形体病、无脑儿等,如果不是特急建议等一等。如果感到身体出现不适的症状,应立即去医院看医生。
甲醛已被国际癌症研究机构(IARC)列为第一类致癌物质,这些年因为甲醛超标致白血病的例子很多,因此,居室内的甲醛污染问题不可轻视。

装修污染物中甲醛对人体危害最严重,潜伏期最长,被称为“室内污染第一杀手”;甲醛是导致新生儿畸形、儿童白血病、青少年记忆力和智力下降的主要原因,被WHO (世界卫生组织) 确定为“致癌和致畸性物质”。

刺激作用:甲醛会对皮肤黏膜产生刺激作用,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。
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。
致突变作用:高浓度甲醛还是一种基因毒性物质;可引起鼻咽肿瘤、白血病、胎儿染色体异常等。
突出表现:头痛、头晕、乏力、恶心、呕吐、胸闷、眼痛、流泪、嗓子痛、胃纳差、心悸、失眠、体重减轻、记忆力减退以及植物神经紊乱等;孕妇长期吸入可能导致妊娠期综合征、胎儿畸形,甚至死亡,女性月经紊乱、儿童智力下降;男子长期吸入可导致男子精子畸形、死亡等。

回答3:

甲醛的危害很多,长期生活在甲醛过多的环境总,会有以下几种表现:

  1. 致敏:会导致皮肤炎症;

2.皮肤黏膜:会有头部疼痛,辣眼睛的表现;

3.对于孕妇:会导致胎儿畸形、严重的话还会死亡;

4.对于儿童:会影响智力的发展。
