How harmful is the smell of decoration to people?

Decoration is a very popular activity in modern society. Due to the rapid development of modern real estate, more and more people can buy houses. Everyone attaches great importance to decorating their own houses beautifully. However, decoration can also bring some problems to people. For example, there are many kinds of decoration smells, and most of them are harmful to the human body. Let's take a look at how much harm the decoration smell can cause to people?

According to the national standard "Code for Indoor Environmental Pollution Control of Civil Construction Engineering", harmful gases in newly renovated rooms are controlled by five pollutants: free formaldehyde, benzene, ammonia, radon and TVOC.

formaldehyde

It is a colorless, soluble, irritating gas. Artificial boards such as particleboard, density board, plywood, adhesives and wallpaper are the main sources of formaldehyde in the air, with a release period of up to 3 to 15 years. Formaldehyde can be absorbed through the respiratory tract, and its harm to the human body is long-term, latent and hidden. Long-term inhalation of formaldehyde can cause serious diseases such as nasopharyngeal cancer and laryngeal cancer.

Benzene is a colorless gas with a peculiar aromatic odor. Glues, paints, coatings and adhesives are major sources of benzene in the air. When benzene and benzene derivatives are inhaled by the human body, they can cause central nervous system anesthetic effects; they can inhibit the body's hematopoietic function, causing a decrease in red blood cells, white blood cells, and platelets, and an increased incidence of aplastic anemia; they can also cause menstrual abnormalities in women and congenital defects in the fetus.

radon

It is a colorless, odorless, undetectable inert gas. Building materials such as cement, bricks, sand, marble, and tiles are the main sources of radon, and a large amount of radon will also be released in geological fault zones. Radon and its progeny enter the human body with the air, and either attach to the tracheal mucosa and the surface of the lungs, or dissolve into body fluids and enter cell tissues, forming internal radiation and inducing lung cancer, leukemia and respiratory tract lesions. Research by the World Health Organization shows that radon is the second largest carcinogen in causing lung cancer, second only to smoking.

Ammonia is a colorless gas with a strong pungent odor. It mainly comes from admixtures such as concrete antifreeze and flame retardants in fireproof panels. It has a strong irritating effect on the eyes, throat, and upper respiratory tract, and can cause poisoning through the skin and respiratory tract. In mild cases, it can cause congestion, increased secretions, pulmonary edema, bronchitis, and dermatitis. In severe cases, laryngeal edema and laryngeal spasm may occur. It can also cause breathing difficulties, coma, shock, etc. High ammonia content can even cause reflex respiratory arrest.
