在我国有毒化学品优先控制名单上甲醛高居第二位。 Formaldehyde is a highly toxic substance, and formaldehyde ranks second on the priority list of toxic chemicals in China. 世界卫生组织 确定为致癌和致畸形物质，是公认的变态反应源，也是潜在的强 致突变物 之一。 Formaldehyde has been identified by the World Health Organization as a carcinogenic and teratogenic substance, it is a recognized source of allergies, and it is also one of the potential strong mutagens . Studies have shown that formaldehyde has strong carcinogenic and pro-carcinogenic effects. The effects of formaldehyde on human health are mainly manifested in abnormal smell, irritation, allergies, abnormal lung function, abnormal liver function, and abnormal immune function. 0.06-0.07mg/m3 时，儿童就会发生轻微气喘；当室内空气中甲醛含量为 0.1mg/m3 时， 就有异味和不适感；达到 0.5mg/m3 时，可刺激眼睛，引起流泪；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；达到 30mg/m3 时，会立即致人死亡。 When its concentration reaches 0.06-0.07mg / m3 per cubic meter of air , children will develop mild asthma; when the formaldehyde content in indoor air is 0.1mg / m3 , there will be odor and discomfort; when it reaches 0.5mg / m3 It can irritate the eyes and cause tears; When it reaches 0.6mg / m3 , it can cause throat discomfort or pain; At higher concentrations, it can cause nausea and vomiting, coughing, chest tightness, asthma and even pulmonary edema; When it reaches 30mg / m3 , it will immediately cause death. . Through animal experiments, research on the level of molecular biology has confirmed the genotoxic and carcinogenic effects, neurological and reproductive toxicity effects of indoor formaldehyde pollution on the human body, oxidative damage to fine oxygen, eye and airway stimulating effects, and Toxic reaction.
“ 十五 ” 科技攻关课题 “ 室内空气重点污染物健康危害评价技术研究 ” 的子课题，杨旭等研究人员采用仿真染毒技术，依据室内甲醛一般污染水平，分别以 2.24 毫克 / 立方米和 4.81 毫克 / 立方米气态甲醛灌流小鼠，通过分子生物标志物观察到气道（鼻腔和支气管）出现神经元性水肿和炎症。 As a sub-topic of the national " Tenth Five-Year Plan" scientific and technological research topic " Research on the Evaluation of Health Hazards of Key Indoor Air Pollutants " , researchers such as Yang Xu and others used simulated poisoning technology, and based on the general indoor formaldehyde pollution levels, 2.24 mg / m3 respectively And 4.81 mg / m3 of gaseous formaldehyde in mice, neuronal edema and inflammation were observed in the airways (nasal cavity and bronchi) through molecular biomarkers. When the level of formaldehyde exposure increased, the blink frequency of test volunteers increased correspondingly, suggesting that the higher the concentration of formaldehyde, the stronger the eye irritation. 3 毫克 / 立方米浓度的甲醛气体对小鼠暴露 7 天，每天 6 小时，研究人员发现小鼠脑、心、肝、肺、肾、睾丸等脏器中具有抗氧化作用的谷胱甘肽水平及 超氧化物歧化酶 （ SOD ）、谷胱甘肽过氧化物酶的活力都有所下降，说明甲醛除造成呼吸道损伤外也能引起其他脏器或系统的氧化损伤，是一种全身性毒物。 The mice were exposed to formaldehyde gas at a concentration of 3 mg / m3 for 7 days and 6 hours a day. The researchers found that the mice's brain, heart, liver, lung, kidney, testis and other organs had antioxidant glutathione The levels and activities of superoxide dismutase ( SOD ) and glutathione peroxidase have decreased, indicating that formaldehyde can also cause oxidative damage to other organs or systems in addition to causing respiratory tract damage. It is a systemic poison.
3-15 年，其对人体尤其是婴幼儿、孕期妇女、老人和慢性病患者甚为严重。 Formaldehyde is now widely regarded as an indoor killer, and its release period is generally 3-15 years. It is very serious to the human body, especially infants, pregnant women, the elderly and patients with chronic diseases. The release period of toxic gases in the air is long, and it is not easy for residents to detect when the level is slightly exceeded. Residents can only smell when they exceed the standard by four or five times. Finding a formal testing agency for formaldehyde testing has become an indispensable procedure for moving into a new home.
用的是 ts1230 分光技术，这项技术可对室内污染物进行分光比色， 得到准确的数值。 At present, the indoor air detection in the industry uses the ts1230 spectroscopic technology. This technology can spectrophotometrically compare indoor pollutants to obtain accurate values. The detection of indoor air requires the use of professional testing equipment, which can simultaneously detect six indoor pollutants. tvoc 、氨。 Including formaldehyde, benzene, toluene, xylene, tvoc , ammonia. The air detection reagent needs to be prepared in advance, and it cannot be left in the sun for a long time, and it is easy to lose its efficacy. 12 个小时，在此期间需禁止吸烟等一切会影响到检测结果的室内活动。 The indoor space must be sealed for 12 hours before the test . During this period, smoking and other indoor activities that will affect the test results must be prohibited.
Newly-married and new-home families have become the focus of attention due to the formaldehyde hazards caused by decoration. “ 传统方法 ” 。 Through investigation, it was found that in order to avoid formaldehyde damage, most users mostly adopt the method of postponing check-in and opening the window to ventilate, while also adopting " traditional methods " such as placing green plants, activated carbon and grapefruit peel . However, the comparative experiment conducted by the Eco-Environment Research Center of the Chinese Academy of Sciences also reminded many users. 94 小时后检测可净化空气，但达到***值时候也会停止净化。 For example, activated carbon can adsorb formaldehyde, but the adsorption stops when it is in a saturated state. The longest method of placing green plants has been found through experiments that the air can be purified after testing for 94 hours, but it also reaches *** Will stop purification.
Nowadays, with the improvement of the quality of life, in order to make people live more comfortable and at ease, most people will consider the beautiful matters of the indoor specialization of indoor formaldehyde management company, but the quality of life, but the decoration of the house, the wall Many paints and paints, window painting and other places will contain the presence of toxic gas. When this toxic gas is serious, it can cause human cancer and even leukemia.
At present, the environmental protection of home improvement has gradually attracted the enthusiastic attention of the majority of netizens. Complaints about pollution of interior decoration have become a hot topic of discussion in the home and environmental protection circles. Pediatricians point out that indoor pollution caused by improper use of decorative materials due to the splendid pursuit of surface decoration is the main cause of physical health, especially the increase in the risk of leukemia and upper respiratory infections in children. The old man was contaminated by home pollution.
