Does formaldehyde have a smell?

Everyone should be familiar with formaldehyde. Formaldehyde will exist in newly renovated houses. Formaldehyde is a substance that is very harmful to human health. It is a colorless and highly irritating gas. If the formaldehyde content in a house exceeds the standard, it will enter our blood through our respiratory system, which is extremely harmful to our health. If you live in an environment with excessive formaldehyde for a long time, you are prone to adverse reactions such as headaches, dizziness, nausea, vomiting, palpitations, insomnia, memory loss, weight loss, etc. Moreover, why more and more children are suffering from leukemia nowadays, one of the reasons is largely related to formaldehyde. Therefore, for new houses, we must thoroughly remove formaldehyde.

Does formaldehyde have an odor?

Formaldehyde is a colorless, highly irritating gas, but the irritation here does not refer to how strong the smell is. The "smell" of formaldehyde generally refers to the stimulation to human respiratory organs under high concentration conditions in a space. Strictly speaking, formaldehyde has no smell. If the formaldehyde level exceeds the standard by less than three times, you will not be able to smell it. Formaldehyde that enters the human body through the respiratory system can quickly enter the blood through alveolar exchange, causing great harm to the human body. Formaldehyde is a gas at room temperature and usually appears in the form of an aqueous solution. A 35-40% formaldehyde aqueous solution is called formalin.

In addition, there are slight differences in the formaldehyde smell on different objects: 1. The formaldehyde smell on furniture is that kind of sawdust smell, wood smell, and wood residue smell. It is the smell of wood mixed with formaldehyde. Merchants generally say that this is the smell of wood and it will disappear after ventilation. Don't believe it. It is not actually the smell. It is just the smell of formaldehyde. 2. The formaldehyde smell on fabrics and curtains is usually emitted by the fabric mixed with formaldehyde. It has a sour and pungent smell, like gasoline, but it is more unpleasant than gasoline and a bit like burnt plastic. 3. The paint smell on the furniture is a mixture of benzene, formaldehyde and banana oil.

What are the hazards of formaldehyde to human body?

1. Irritation: The main hazard of formaldehyde is its irritation to the skin and mucous membranes. Formaldehyde is a protoplasmic toxic substance that can bind to proteins and cause severe respiratory irritation and edema, eye irritation, and headaches when inhaled in high concentrations.

2. Sensitization effect: Direct contact of skin with formaldehyde can cause allergic dermatitis, pigmentation, and necrosis. Inhalation of high concentrations of formaldehyde can induce bronchial asthma.

3. Mutagenic effect: High concentration of formaldehyde is also a genotoxic substance. Experimental animals may develop nasopharyngeal tumors if they inhale high concentrations in the laboratory.

4. Prominent symptoms include headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, poor appetite, palpitations, insomnia, weight loss, memory loss and autonomic nervous system disorders; long-term inhalation by pregnant women may cause fetal malformation or even death, and long-term inhalation by men may cause sperm malformation and death.
