In this issue, we have gathered six major air pollutants that may come into the home with furniture, furniture, supplies, and office equipment, and tell you about the channels they may invade, the possible hazards, and the way to get rid of them.
No. 1 pollutant: benzene contains benzene, toluene, xylene, benzopyrene
Source and presence: Benzene is mainly found in chemical products such as paints, coatings, latex paints, and various decorative materials containing benzene.
Health hazard: After inhalation of benzene series by the human body, central nervous system anesthesia can occur; it can inhibit the hematopoietic function of the human body, increase the prevalence of aplastic anemia; it can also lead to congenital defects of the fetus.
National Standard: The Code for Indoor Environmental Pollution Control of Civil Buildings stipulates that benzene content of Class I and Class II civil construction projects are required to be ≤0.09 mg/m3.
Coping strategy: It is necessary to choose decorative materials that meet the national standards, especially paints, coatings, adhesives and waterproof materials. It is best to choose water-based wood lacquer. The benzene series volatilizes quickly, maintains good ventilation after renovation, and can be accommodated after a few months of inactivity. It is best to contact a professional indoor environmental testing agency to check the degree of benzene contamination before you check in.
No. 2 pollutant: formaldehyde
Source and presence: Cement wall with water reducing agent is usually added with formaldehyde, which is the main source of formaldehyde pollution. Plywood, density fiberboard, particleboard in furniture and cabinet materials... Formaldehyde is released when exposed to heat and humidity. Unqualified paints and latex paints, adhesives, fabrics, carpets, etc. are sources of formaldehyde release.
Health hazards:
Formaldehyde and benzene are two major pollutants that cause leukemia. Long-term exposure to low doses of formaldehyde can cause chronic respiratory diseases, causing cancer and leukemia, and children and pregnant women are particularly sensitive to formaldehyde.
National standard:
The "Code for Indoor Environmental Pollution Control of Civil Buildings" stipulates that the formaldehyde content should be ≤0.08 mg/m3 for Class I civil construction projects and ≤0.12 mg/m3 for Class II civil construction projects.
preventive solution:
Users can purchase formaldehyde detectors to evaluate the indoor formaldehyde pollution situation, which is simple and easy. If the test result is suspicious, you should immediately contact the professional organization to check the degree of formaldehyde pollution and take control measures. When decorating the materials, you need to consider whether it will cause formaldehyde pollution. After renovation, it is best to ventilate for 3 months to half a year. In addition, open windows as much as possible and install new fans if available.
No. 3 pollutant: ammonia
Source and presence:
Most of the ammonia is released from the wall. The area of ​​the wall determines the amount of ammonia released. The degree of ammonia pollution in the air in different rooms is also different.
Health hazards:
Ammonia can weaken the body's resistance to disease. After ammonia is inhaled into the lungs, it destroys the oxygen transport function. Inhalation of a large amount of ammonia in a short period of time can cause various discomforts. In severe cases, pulmonary edema and adult respiratory distress syndrome can occur.
National standard:
The Indoor Air Quality Standard stipulates that the ammonia concentration needs to be ≤0.2 mg/m3.
preventive solution:
It is necessary to detect the degree of ammonia pollution through a professional indoor environmental testing agency, and take measures to control. In addition, open windows as much as possible, and install new fans if available.
