Formaldehyde is a harmful substance that people are very afraid of, especially when the new home is decorated, people are most worried about the formaldehyde content and formaldehyde residue in the house. The most important reason why the newly decorated house can't move in immediately is also because of the price of formaldehyde. Formaldehyde is a harmful chemical substance with strong pungent smell, which is particularly harmful to children and can even threaten children's names. So how serious is the harm of formaldehyde to people? This article introduces the harm of formaldehyde to human body. Let's have a look.
&# 8203;&# 8203;&# 8203;&# 8203;&# 8203;&# 8203; What harm does formaldehyde have?
1： Cause leukemia, cancer and other diseases
Experts pointed out that environmental factors are one of the important causes of leukemia. The use of materials containing excessive chemical elements such as formaldehyde and benzene in decoration has become one of the key factors leading to leukemia. The study animals found that rats were exposed to 15 & mu per cubic meter; G formaldehyde can cause nasal cancer for 11 months. According to the latest research results released by the National Cancer Institute of the United States on May 12, 2009, workers in chemical plants who are frequently exposed to formaldehyde are much more likely to die of blood cancer, lymphatic cancer and other cancers than workers who are less exposed to formaldehyde. The researchers investigated 25000 chemical plant workers who produced formaldehyde and formaldehyde resin. The results showed that the mortality of those who had the most exposure to formaldehyde was 37% higher than those who had the least exposure.
2： Stimulate and paralyze nerves, making immunity low
Long term inhalation of formaldehyde gas will paralyze the human nervous system and may cause motor dysfunction. If treatment is not timely, it will be the disorder of the human nervous system, resulting in the decline of human immunity.
3： Damage to smell
We often judge the taste of objects through smell. Smell is very important in our life, and formaldehyde is an odor molecule. We can easily perceive the smell of formaldehyde through smell. It mainly enters the body through nose breathing, because formaldehyde is highly toxic. In the process of breathing, formaldehyde does great harm to smell, and the smell of formaldehyde is pungent, It makes people feel uncomfortable in mouth and nose, and even causes nasopharyngeal carcinoma in severe cases.
4： Injury to respiratory system
Formaldehyde is mainly inhaled into the human body through nose breathing, causing harm to the human body. The most direct harm must be the respiratory system. Inhalation of excessive formaldehyde will seriously stimulate human respiratory tract, and even lead to dyspnea and death; Long term inhalation of a small amount of formaldehyde will lead to respiratory tract irritation, edema, eye tingling, headache, bronchial asthma and difficulty in breathing.
5： Harm to lung and liver function
The lung is the respiratory organ of the human body. Inhaling too much formaldehyde into the body will cause respiratory system disorder and make people difficult to breathe; In severe cases, it will damage the internal organs such as lung and liver, and cause inflammation and other diseases; More serious can cause cancer.
6： Memory loss stimulates the human brain
After inhaling different amounts of formaldehyde, it will also reduce people's memory and stimulate people's brain; A small amount of inhalation will cause neurological symptoms, such as memory loss, headache, dizziness and autonomic nerve dysfunction, as well as panic, nausea, vomiting and other serious symptoms, such as insomnia, fatigue, weight loss, paranoia and depression; Endanger people's mental health.
7： It has a significant impact on reproductive function
In the Chinese people's consciousness, it is a very important thing in one's life to breed future generations. The so-called most unfilial is that there is no future. In fact, many environmental factors now affect people's fertility; Among them, the effects of formaldehyde on fertility vary from person to person, some have serious consequences and some are recessive injuries, which are mainly reflected in these aspects: after long-term inhalation of formaldehyde, adult men will have decreased sperm motility and dead sperm; After long-term inhalation of formaldehyde, women will lead to infertility, fetal malformation or stillbirth; It affects the development of fetal immune system, makes newborns vulnerable to diseases, congenital asthma and affects the intellectual development of newborns; Endanger human health.
The harm of formaldehyde can not be ignored. In order to avoid the harm of formaldehyde, the first thing we need to do is to reduce the use of home decoration materials with high formaldehyde content and choose products with high environmental protection index as much as possible. In addition, don't panic when encountering formaldehyde, and choose the correct formaldehyde removal method for treatment.
