      Generally, new houses have just been renovated, and most people will choose to leave them vacant for a period of time before moving in because they are worried that the formaldehyde will exceed the standard. Do you think there is only formaldehyde pollution in newly renovated houses? In fact, not only formaldehyde, but also volatile organic compounds such as benzene series, ammonia, TVOC, and so on cause indoor air pollution, and this kind of indoor air pollution gas will also damage the health of everyone, and it also needs attention. Let's learn about the major pollution sources together!

 

Benzene and benzene series

Hazards: Benzene is a colorless vapor with a distinctive aroma and has been identified as a significant carcinogen by the World Health Organization. Benzene is a major cause of the rise in acute leukemia patients in recent years. According to the survey data, among the acute leukemia patients in metropolitan cities, 90% of their families have had house renovations within one year. When everyone inhales benzene with a high concentration in a short time, the central nervous system anesthetic effect will occur, ranging from dizziness, headache, nausea and vomiting, nausea and retching, palpitation, shortness of breath, fatigue, etc., to fainting. Even death due to the decline of breathing and circulatory system! Long-term exposure to certain ingredients of benzene will lead to chronic poisoning, headache, insomnia, listlessness, memory loss and other depression and anxiety.

formaldehyde

Hazards: Formaldehyde is a permeable vapor that has been identified by the World Health Organization as a hazardous substance and a fetal malformation compound. Formaldehyde releases air pollution, which can cause tears in the eyes, inflammation of the cornea and subconjunctiva, skin allergies, throat discomfort, dry cough, acute and chronic bronchitis and other respiratory diseases, and can also cause nausea and vomiting, nausea and dry retching, gastrointestinal function. disorder! In more severe cases, it can also lead to persistent headaches, new coronary pneumonia, acute pulmonary edema, loss of appetite, and even death. Long-term exposure to doses of formaldehyde can cause chronic respiratory diseases, ophthalmic diseases, irregular menstruation in women, pregnancy syndrome, neonatal developmental deformities, depression and anxiety. Heart disease in children. According to the survey of American medical enterprises, the air pollution released by formaldehyde is the key reason for the increase of bronchitis in children aged 3-5 years.

ammonia

Hazards: Ammonia is a colorless vapor with a pronounced pungent odor and is lighter than vapor (0.5 percent). Ammonia is an alkaline substance, which has corrosive and irritating effects on all involved skin tissues. It can digest water in skin tissues, juvenile tissue proteins, and make tissues body fat and oily, and damage cell membrane structure. . When the concentration value is too high, in addition to corrosion, it can also lead to cardiac arrest and respiratory arrest based on the reverse action of trigeminal nerve endings. Therefore, the damage of alkaline substances to the structure is deeper and more serious than that of acidic substances.

TVOC

Hazards: volatile organic compounds (TVOC) mostly refer to compounds with a melting point of 50-250. According to their different chemical structures, they are further divided into eight categories; alkanes, paraxylenes, alkenes, halogenated hydrocarbons Compounds, substituted hydrocarbons, phenothiazine and others. TVOC can lead to imbalance of the human immune system, damage the central nervous system, dizziness, headache, easy drowsiness, drowsiness, palpitation, shortness of breath and other active symptoms; it is also likely to endanger the digestive system, such as loss of appetite, nausea and vomiting, etc. In severe cases, it can harm the liver and hematopoietic system and cause side effects in the central nervous system.

The renovation of the new house is completed, and the indoor air purification must be done well! Because the cases of indoor pollution causing human injury are not uncommon, we once again appeal to everyone, in order to better protect the physical and mental health of you and your family, you must pay enough attention to indoor decoration pollution, so that your family will not be endangered.
