What is formol?
Formol is an organic compound, commonly referred to as Formaldehyde, methyl aldehyde, methylene oxide, methanol, and aldehyde. This substance has the chemical formula HCHO, which is a saturated solution of formaldehyde in water and can change to a gaseous form under normal conditions.

If this solution is about 40% by volume or 37% by mass, it is colorless, difficult to smell, has a pungent odor and is highly soluble in water. This substance was first discovered in 1859 by the Russian chemical chemist Aleksandr Butlerov and was definitely identified in 1867 by another scientist, Hoffman.
In nature, Formol can be found in wood, apples, tomatoes, tobacco smoke, engines, petroleum, and engines.
This is a substance used in industry with processed products such as: varnish, pressed wood, paint, flame retardants, preservatives, insulation, plastics, paper...

How dangerous is Formol to human health?
Formol has been changed from a group of substances capable of causing cancer (2A) to a group of carcinogens (1) by the International Center for Cancer Research by the International Center for Research on Cancer. In recent years, the rate of people suffering and dying from cancer has increased mainly because of eating foods containing Formol.
According to the summary of the Central Cancer Hospital, every year our country has 150,000 more cases of cancer, of which up to 50,000 cases are caused by eating contaminated food and formol in food is also among them. .
Formol causes the most dangerous harm to humans when exposed through inhalation. At that time, this poison can lead to burns of eyes, nose, respiratory system, neck pain, larynx, bronchitis, pneumonia, dermatitis and skin allergies. When people are infected with Formol through the respiratory tract or the gastrointestinal tract to a severe degree, some dangerous phenomena may occur as follows:
- Cell necrosis
- Vomiting blood. Diarrhea or urinating
- Cardiovascular collapse can lead to death within minutes (with only 30ml of Formol, it can cause death)

The limit that is still safe for humans in the air is less than 2 ppm. Experiments on mice showed that mice living in formol environment with concentrations of 6 to 15 ppm lead to tissue cancer. The Formol is a saturated solution of formaldehyde in water. Formaldehyde is a chemical with a very characteristic pungent odor that is widely used in industry. Formaldehyde can form from human activities (burning garbage, cigarette smoke,...). Formaldehyde has antibacterial, antifungal, bactericidal mechanism like other bactericidal agents, that is, "kills" cell tissues.

How dangerous is Formol?
Formaldehyde gas May cause burns to the nose, eyes, respiratory system, sneezing, neck pain, laryngospasm, bronchitis and pneumonia. Formaldehyde can also cause dermatitis or skin allergies. According to the World Health Organization, humans are most at risk from inhalation of formol.
If severe formaldehyde poisoning through inhalation or gastrointestinal tract the following phenomena may occur: Ulcers, cell necrosis, manifestations of vomiting blood, diarrhea or bloody urine and possibly cause death within minutes due to cardiovascular collapse, with other accompanying symptoms such as abdominal pain, vomiting, cyanosis. 30ml is a potentially lethal dose.
Research has shown that the safe human limit for Formol in the air is less than 2 ppm. Environments with formol concentrations of 6 to 15 ppm can lead to tissue cancer in mice. In addition, research also shows an effect of formol on liver, pancreatic and lung functions.
Formol in high concentrations when converted to formic acid, thereby increasing the amount of acid in the blood, causing rapid and rapid breathing, decreased body rhythm, coma, weakened immune system, and even death. death.
At elevated temperatures, formol toxicity is also increased. At low temperatures, this substance can also be converted into another very toxic substance, paraforomaldehyde.
Harm of Formol to human health
Formaldehyde does not exist independently, but exists in the form of solutions or other compounds and only vaporizes when the conditions are right (when humidity and temperature increase), so the existence of formaldehyde in the indoor environment (due to wood, curtains, pillows, bed sheets, seat cushions, carpets and plastic products used in the house...) is always higher than the outdoor environment. Therefore, formaldehyde pollution to human health is continuous and cumulative.

Formal substance always exists with other compounds or in solution rather than independently. This substance vaporizes only during pouring moisture and increasing temperature. Formol concentrations contained in objects around people are often higher than in the external environment, it will infect the body and accumulate.
When exposed to Formol for a long time, whether at high or low concentration, the human body is also receiving serious harm to the respiratory system, skin, leukemia, and cancer. especially lung and nasopharyngeal cancers.
Besides, Formol is also considered to be the cause of chromosomal aberrations and mutations. Therefore, when women ingest this substance during pregnancy, it will have an adverse effect on the development of the fetus.

How to avoid Formol . infection
With the harmful effects of chemicals that often appear in these poor-quality foods, consumers must be very alert and careful when choosing quality, formol-free consumer products to protect their health. family and loved ones against the toxins of this chemical.
It is best to check foods with form-checking tools that have been inspected and licensed by the Ministry of Public Security.
When you find yourself showing signs of poisoning or poisoning, you need to go to medical facilities for diagnosis and treatment.
With the information about Formol that the admission board of HCMC Pharmacy College - Pham Ngoc Thach Medical College has provided, everyone must have had an understanding of the dangers of this chemical from which there are ways to avoid it. and effectively handle it to protect the health and safety of yourself and your family.
