甲醛人体危害
Formaldehyde harm to human body
有关资料表明:室内空气污染比室外高5~10倍,污染物多达500多种。室内空气污染已成为多种疾病的诱因,而甲醛则是造成室内空气污染的一个主要方面。
Relevant data show that indoor air pollution is 5-10 times higher than outdoor air pollution, and there are more than 500 kinds of pollutants. Indoor air pollution has become the inducement of many diseases, and formaldehyde is one of the main aspects of indoor air pollution.
甲醛对健康危害主要有以下几个方面:
Formaldehyde is harmful to health in the following aspects:
a、刺激作用:甲醛的主要危害表现为对皮肤黏膜的刺激作用,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。
A. stimulating effect: the main harm of formaldehyde is the stimulating effect on skin and mucous membrane. Formaldehyde is a kind of protoplasm toxic substance, which can combine with protein and cause serious respiratory tract stimulation and edema, eye irritation and headache when inhaled in high concentration.
b、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。
B. sensitization: direct contact of skin with formaldehyde may cause allergic dermatitis, pigmentation and necrosis. Inhalation of high concentration formaldehyde may induce bronchial asthma.
c、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。
C. mutagenicity: high concentration formaldehyde is also a genotoxic substance. Experimental animals can cause nasopharyngeal tumor when inhaled with high concentration in the laboratory.
d、突出表现:头痛、头晕、乏力、恶心、呕吐、胸闷、眼痛、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胎儿畸形,甚至死亡;男子长期吸入可导致男子精子畸形、死亡等。
D. outstanding performance: headache, dizziness, fatigue, nausea, vomiting, chest distress, eye pain, throat pain, poor appetite, palpitation, insomnia, weight loss, memory loss and autonomic nervous disorders. Long term inhalation of pregnant women may lead to fetal malformation or even death; long term inhalation of men may lead to sperm malformation and death.
危险特性:
Hazard characteristics:
其蒸气与空气形成爆炸性混合物,遇明火、高热能引起燃烧爆炸。若遇高热,容器内压增大,有开裂和爆炸的危险。
Its vapor and air form explosive mixture, which can cause combustion and explosion in case of open fire and high heat. In case of high heat, the internal pressure of the vessel increases, and there is a risk of cracking and explosion.
燃烧(分解)产物:一氧化碳、二氧化碳。
Combustion (decomposition) products: carbon monoxide, carbon dioxide.
相对浓度危险度
Relative concentration risk
当甲醛浓度在每立方米空气中达到0.06-0.07mg/m³时,儿童就会发生轻微气喘;
When formaldehyde concentration reaches 0.06-0.07mg/m3, children will have slight asthma;
当室内空气中甲醛达到0.1mg/m³时,就有异味和不适感;
When formaldehyde in indoor air reaches 0.1mg/m3, there will be peculiar smell and discomfort;
甲醛达到0.5mg/m³时,可刺激眼睛,引起流泪;
When formaldehyde reaches 0.5mg/m3, it can stimulate eyes and cause tears;
甲醛达到0.6mg/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;
Formaldehyde reaches 0.6mg/m3, which can cause discomfort or pain in the throat. When the concentration is higher, it can cause nausea and vomiting, cough and chest tightness, asthma and even pulmonary edema;
甲醛达到30mg/m³时,会立即致人死亡。
When formaldehyde reaches 30mg / m3, it will immediately cause death.
