Usually, after the home decoration, it takes a while to stay in, because there is a harmful gas such as formaldehyde in the newly renovated house. There are many disadvantages in sucking into our body. Home decoration air The quality of the occupants is directly related to the health of the occupants, so it is necessary to detect the air. So, what are the indoor air testing projects? What are the air conditioning methods for interior decoration? 1. What are the indoor air testing projects? 1. Formaldehyde is the most common irritant gas after interior decoration. It is a colorless and easily soluble irritant gas. Artificial boards, adhesives and wallpapers such as particleboard, MDF and plywood are the main sources of formaldehyde in the air, with a release period of 3 to 15 years. It can be absorbed through the respiratory tract, and the harm of formaldehyde to the human body has the characteristics of long-term, latent and concealed. Long-term inhalation of formaldehyde can cause serious diseases such as nasopharyngeal cancer and throat cancer. 2. Benzene is also an irritating gas that is harmful to the body and is a colorless, special aromatic odor. Glues, paints, coatings and adhesives are the main sources of benzene in the air. When benzene and benzene are inhaled by the human body, central nervous system anesthesia can occur; it can inhibit the hematopoietic function of the human body, reduce red blood cells, white blood cells, thrombocytopenia, and increase the prevalence of aplastic anemia; it can also cause abnormal menstruation in women and congenital Defects, etc. 3, æ°¡ is also a colorless, odorless, undetectable inert gas. Building materials such as cement, brick sand, marble, and ceramic tiles are the main sources of plutonium, and there will be a large amount of plutonium in the geological fault zone. The sputum and its daughters enter the human body with the air, or adhere to the mucosa of the trachea and the surface of the lungs, or dissolve into the body tissues to form radiation in the body, and induce lung cancer, leukemia and respiratory diseases. World Health Organization research shows that sputum is the second most common cancerous substance that causes lung cancer after smoking. 4. Ammonia is a colorless gas with a strong pungent odor. It mainly comes from admixtures such as concrete antifreeze and flame retardant in fireproof board. It has a strong stimulating effect on the eyes, throat and upper respiratory tract. It can cause poisoning through the skin and respiratory tract. It can cause congestion, increased secretion, pulmonary edema, bronchitis and dermatitis. In severe cases, it can cause laryngeal edema and throat. Causes breathing difficulties, coma, shock, etc., high levels of ammonia can even cause reflex breathing to stop. Second, indoor decoration air detection method 1. Precision measurement method (instrument analysis method) can be used, including high performance liquid chromatography (HPLC), gas chromatography (DNPH-GC method) and spectrophotometry recommended by the World Health Organization; 2, simple measurement method is a simple detection method, mainly used for rapid detection, its accuracy is not high. There are mainly electrical law methods, which can display the measurement data, as well as the detection tube method and the measurement paper method, that is, the detection gas concentration is determined by detecting the color change exhibited by the gas reaction with the indicator. Air detection necessity 1. Indoor air pollutants will cause great harm to the body in a short period of time, while others have a long incubation period. Usually the time is 3-15 years. Such as radioactive pollution, the incubation period is several decades. 2. The indoor environment is the main place where people live and work. At least 80% of a person's life is spent indoors, so that exposure to a polluted indoor air environment for a long time, the harm of pollutants to the human body is more serious.
