Formaldehyde is a colorless soluble irritant gas, can not detect lower concentrations. [Harm] long-term exposure to low doses of formaldehyde can cause chronic respiratory diseases, menstrual disorder, pregnancy syndrome, caused by nasopharyngeal cancer, caused by lower neonatal body, chromosomal abnormalities, and even lead to child leukemia. High concentrations of formaldehyde on the nervous system, immune system, liver and others have poisoned. Meanwhile, formaldehyde also teratogenic and carcinogenic. 2, benzene is highly toxic carcinogen by IARC confirmed benzene slightly fragrant, easily overlooked, can cause leukemia and aplastic anemia. [Harm] long-term inhalation of benzene, can cause chronic poisoning of the human hematopoietic system, nervous system damage, cause aplastic anemia or leukemia. Benzene greater harm to women, women of childbearing age long-term inhalation of benzene can cause menstrual disorders, pregnancy complications, fetal congenital defects. 3. Ammonia is a colorless gas with a strong pungent odor, can not detect low concentrations. [Harm] ammonia contact the organization have corrosion and irritation. Organization can absorb moisture, so that tissue protein denaturation, changes in membrane structure. Usually in the form of ammonia gas is inhaled. After inhalation of low concentrations of ammonia, there may be tears, sore throat, chest tightness, difficulty breathing, accompanied by dizziness, headache, nausea, vomiting, fatigue and other phenomena. Higher concentrations of ammonia into the alveoli, can enter the bloodstream through the alveoli, combined with hemoglobin, oxygen transport function destruction. Lead to pulmonary edema, embolism, and even can cause cardiac arrest. 4, TVOC composition is extremely complicated, it is a comprehensive variety of toxic gases. Mainly from a variety of coatings, adhesives and various artificial materials. TVOC may have odor, showing toxicity, irritation, and some compounds are genotoxic. General indoor air pollution, mostly renovated TVOC pollution. [Harm] TVOC can cause the level of immune disorders affecting the central nervous system function, dizziness, headache, drowsiness, weakness, chest tightness and other symptoms, may also affect the digestive system, loss of appetite, nausea and other business projects to do what, serious even can damage the liver and hematopoietic systems, and other allergic reactions occur. Myth: indoor air pollution control is the elimination of formaldehyde formaldehyde mainly from artificial board, adhesives used in furniture and decoration and carpets and other synthetic fabrics, concentration in excess can cause nausea, vomiting, coughing, chest tightness, wheezing or emphysema business projects, is One of the main pollutants in indoor air. Because it is indoor air pollution, "the number one killer," and thus a higher awareness. Many consumers believe that the elimination of indoor air pollution is the elimination of formaldehyde, it is not. In addition to formaldehyde, a large number of chemical materials from the building decoration materials used, such as paints, solvents, thinners, adhesives BTEX, such as benzene, toluene, xylene, etc., long-term inhalation of high concentrations of benzene in the air easily cause chronic benzene poisoning, caused by atopic dermatitis, laryngeal edema, and thrombocytopenia, may also lead to severe aplastic anemia. Myth: alone ventilation to reduce indoor air pollution Most people know that a good start in the new home decoration first six months and then stay ventilation, ventilation helps to release formaldehyde, benzene and other harmful substances. But the fact is because the decoration pollution caused by chemical glue plate and furniture toxic glue formaldehyde release time of up to 5 years to 15 years, opened a few months window is useless. Of course, is one way to reduce the ventilation window of indoor pollution, but blindly relying solely on ventilation, does not fundamentally solve the problem of indoor air pollution at all.
