There are two situations of decoration pollution: one is that the decoration materials themselves are non-environmental protection products. For example, the plates and furniture used are non-environmental protection products. After such decoration, pollution is inevitable in the room. There are hundreds of volatile organic compounds in modern indoor air, and dozens of them are harmful to the human body. It is generally believed that the most important pollutants are as follows.
It is a colorless liquid with a special aromatic taste, which is a kind of indoor volatile organic compounds. Mainly comes from the organic solvents of glue, lacquer, paint and building materials used in decoration. Mild benzene poisoning can cause drowsiness, headache, nausea, vomiting, chest tightness, etc., and may have mild mucosal irritation. Long-term inhalation of benzene can cause aplastic anemia.
Oxygen is a radioactive inert gas, colorless and odorless. Exist in cement, sand and gravel, indoor pollutant radon pollution is second only to smoking, ranking second in the cause of lung cancer.
3. Total Volatile Organic Compounds
This organic matter can cause dizziness, headache, drowsiness, weakness, chest tightness and other symptoms. Mainly from coatings, adhesives, etc.
Formaldehyde has a strong smell. Can cause severe irritation of the respiratory tract. Direct skin contact with formaldehyde can cause dermatitis. Frequent inhalation of a small amount of formaldehyde can cause chronic poisoning. Formaldehyde mainly comes from the adhesive in man-made boards.
5. Building materials rays
It is mainly radioactive substances produced by the decay of the three radioactive elements of radium, thorium and potassium. If the content of decayable substances is too large, it is harmful to the human body. Mainly come from all kinds of natural stone, sanitary ware, ceramic tile and concrete.
6. Toluene diisocyanate
It has obvious irritation to eyes and respiratory tract. It can cause dryness and pain at the corners of the eyes, loss of vision in severe cases, allergic asthma, and respiratory diseases with bronchitis. At the same time, it can cause allergic dermatitis. In severe cases, it can cause skin cracking and ulceration. It mainly comes from solvent-based wood coatings and adhesives.
7. Heavy metal elements
The solubles of heavy metal elements such as lead, cadmium and mercury are obviously harmful to the human body. Excessive lead can damage the nerves, hematopoietic function and reproductive system. In particular, it is more harmful to children, which can affect children's growth and development and intellectual development. These pollutants mainly come from decoration materials such as solvent-based wood coatings, interior wall coatings, wood furniture, wallpaper, and PVC coiled flooring.
Ammonia is a colorless and strongly irritating gas. Because ammonia is easily soluble in water, it can absorb water in tissues, has a quick effect on the eyes, throat, and upper respiratory tract, and is highly irritating. It can cause poisoning through the skin and respiratory tract. Long-term exposure to low-concentration ammonia can cause pharyngitis and hoarseness; severe cases can cause throat edema, difficulty breathing, coma, shock, etc. Ammonia mainly comes from concrete additives used, especially antifreeze containing urea.
