很多人对甲醛的认知可能只停留在它的功能作用方面:在各种各样的家装建材中,几乎都含有一定量的甲醛,它的主要作用是粘合、硬化固定、防腐、防虫。往往大家会忽视:甲醛也是室内的“隐形杀手”,它会从家装建材中慢慢释放出来,污染了室内空气。
Many people's cognition of formaldehyde may only stay in its function: in all kinds of home decoration building materials, almost all contain a certain amount of formaldehyde, its main function is to bond, harden and fix, antiseptic and insect proof. It is often ignored that formaldehyde is also the "invisible killer" in the room. It will be slowly released from the home decoration materials and pollute the indoor air.
如何确定我们现在居住的环境是否健康呢?更好的方式就是检测一下室内空气中甲醛吧。
How to determine whether the environment we live in is healthy? The best way is to check the formaldehyde in the indoor air.
一、检测甲醛的方法
1、 Method of formaldehyde detection
1、甲醛自测盒
1. Formaldehyde self test box
甲醛自测盒是更简便、客观的甲醛检测方法,不用求人自己动手就可以进行检测。
Formaldehyde self-test box is the most simple and objective formaldehyde test method, which can be tested without asking people to do it by themselves.
甲醛自测盒由中国检验检疫科学研究院研发,依据国家标准甲醛检测采样的“酚试剂比色法”开发。因此,从甲醛自测盒的原理来看,不仅有科学依据,而且符合国家标准所规定的化学检验方法。
The formaldehyde self-test box was developed by China Institute of inspection and quarantine, and was developed according to the national standard formaldehyde detection and sampling "Phenol Reagent Colorimetry". Therefore, from the perspective of the principle of formaldehyde self-test box, it not only has scientific basis, but also conforms to the chemical inspection method stipulated by the national standard.
甲醛自测盒的优点:
Advantages of formaldehyde self-test box:
1、价格便宜、操作简单、选购方便。
1. Low price, simple operation and convenient purchase.
2、可以进行污染释放源检测,更加实用、科学,能够准确找到室内甲醛污染释放源。
2. It is more practical and scientific to detect the emission source of formaldehyde in the room.
3、可以用甲醛自测盒进行验证除甲醛产品的效果,长期监测,以确保室内空气环境的安全。
3. Formaldehyde self-test box can be used to verify the effect of formaldehyde removal products, long-term monitoring, to ensure the safety of indoor air environment.
2、检测单位
2. Professional testing unit
检测机构主要包括两类:一类是研究机构或政府管理属下的业务单位;另一类是民营检测公司。检测都是多项、多点的检测。
There are two types of professional testing institutions: one is a professional research institution or a business unit under the management of the government; the other is a private testing company. Professional tests are multiple and multi-point tests.
委托检测机构需要提前预约,现场采样空气后,带回实验室检验,至少等待2-3个工作日才能出结果,价格比较高。理论上检测结果是更准确的,只有现场操作失误等等人为因素会影响检测结果的准确性。
The entrusted professional testing agency needs to make an appointment in advance. After the air is sampled on site, it will be taken back to the laboratory for testing. It will wait at least 2-3 working days for the results to be obtained. The price is relatively high. In theory, the test results are the most accurate. Only human factors such as on-site operation errors will affect the accuracy of the test results.
此外,市面上还有一类甲醛检测仪器——甲醛检测仪(甲醛速测仪),只要在某宝上就能买到,价格跨度较大,但目前甲醛速测仪的检测原理并不在国标规范中,故不对其进行讨论。
In addition, there is also a kind of formaldehyde detection instrument on the market - formaldehyde detector (formaldehyde speedometer), which can be bought on a certain treasure and has a large price span. However, the detection principle of formaldehyde speedometer is not in the national standard at present, so it is not discussed.
小知识:身体对不同浓度甲醛的反应
Little knowledge: the body's response to different concentrations of formaldehyde
美国专家研究表明,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、免疫功能异常等。
American experts have shown that the main effects of formaldehyde on human health are abnormal smell, stimulation, allergy, abnormal lung function, abnormal liver function, abnormal immune function, etc.
当室内甲醛达到一定浓度时,会对皮肤粘膜产生一定的刺激,也会引起眼红眼痒、咽喉不适、喷嚏、胸闷气喘等。
When indoor formaldehyde reaches a certain concentration, it will produce certain stimulation to skin and mucous membrane, and also cause red eye itching, throat discomfort, sneezing, chest tightness and asthma.
当甲醛浓度过高时,会引起急性甲醛中毒,咽喉烧灼痛、呼吸困难、过敏性皮炎和肺水肿等。
When the formaldehyde concentration is too high, it will cause acute formaldehyde poisoning, sore throat, dyspnea, allergic dermatitis and pulmonary edema.
当长期接触低浓度甲醛时,会引起慢性甲醛中毒,头痛头晕、免疫力降低、神经衰弱、精神抑郁等,更终导致呼吸功能障碍和肝细胞受损甚至癌变。
When exposed to low concentration formaldehyde for a long time, it will cause chronic formaldehyde poisoning, headache and dizziness, decreased immunity, neurasthenia, mental depression, etc., and eventually lead to respiratory dysfunction and liver cell damage or even cancer.
由于儿童正处成长阶段,造血功能不稳定、造血储备能力差,因此甲醛超标对儿童或者青少年造血器官的影响可能比成年人更严重,更有可能引发白血病等疾病。
Because children are in the growing stage, with unstable hematopoiesis function and poor hematopoiesis reserve capacity, the impact of excessive formaldehyde on children's or adolescents' hematopoiesis organs may be more serious than that of adults, and it is more likely to cause leukemia and other diseases.
二、甲醛检测的分类
2、 Classification of formaldehyde detection
1、室内空气检测
1. Indoor air detection
室内空气检测,是为了测定室内空气是否受到甲醛污染,是否达到安全标准,从而知道室内是否可以安全入住为目的检测。
The purpose of indoor air detection is to determine whether the indoor air is polluted by formaldehyde, whether it meets the safety standards, and whether it can be checked in safely.
2、甲醛污染释放源检测
2. Formaldehyde emission source detection
“甲醛污染释放源检测”又简称“污染源检测”,是由全国室内环境净化治理指导副主任陈晓鹏先生提出,是指检测人造板制作的家具如衣柜、床箱、抽屉等内部的甲醛浓度,是判断是否为甲醛污染释放源的直接有效方法。
"Formaldehyde pollution emission source detection", also referred to as "pollution source detection", is proposed by Mr. Chen Xiaopeng, deputy director of the national indoor environment purification guidance center. It refers to the detection of formaldehyde concentration in furniture made of wood-based panel, such as wardrobe, bed box, drawer, etc., which is a direct and effective method to determine whether it is a formaldehyde pollution emission source.
甲醛检测机构不提供污染释放源检测,但可以使用甲醛自测盒自行对疑似污染源的家具内部进行检测。
Professional formaldehyde testing institutions do not provide pollution source testing, but can use formaldehyde self-test box to test the interior of furniture suspected of pollution source.
家具内甲醛污染释放源检测很重要
It is very important to detect formaldehyde emission source in furniture
装修完半年内,家具、装修中用到的人造板,甲醛释放量约占80%左右;装修完半年以上,甲醛释放几乎100%来源于家具、装修中的人造板。
Within half a year after decoration, about 80% of formaldehyde is released from wood-based panels used in furniture and decoration; over half a year after decoration, almost 100% of formaldehyde is released from wood-based panels used in furniture and decoration.
