Most people usually work more than 80% of the time of life is indoors, so indoor air quality must value! There are several reasons of indoor air pollution, such as air pollution, air pollution in the kitchen, office, bedroom air pollution and so on, so the air pollution would have a very busy harm to human body health?
We have a lot of air pollution that can be seen everywhere in our daily life, such as cooking in the kitchen lampblack is away to the other bedroom, adsorption on the wall, clothing and furniture, more importantly it contains carcinogenic mutations. In the winter to keep warm in flue gas produced by the burning coal, contains a lot of carcinogenic PAH. Survey found that the north of farmers in areas prone to lung cancer lung cancer one reason is burning honeycomb briquet winter home do not install the chimney. Liquefied petroleum gas (LPG) combustion particulate matter in dichloromethane extracts, containing nitro polycyclic aromatic hydrocarbons, it is a strong mutagenic. Especially some producing area of coal containing more fluorine, arsenic and other inorganic contaminants, burning after the indoor air pollution.
And indoor clean, damp and hot environment of allergenic biological breeding. The main indoor sensitization creatures are fungi and dust mites. Mainly from poultry, dust, etc. Fungus breeding ability is very strong, as long as a little water and organic matter, which can grow. Such as internal, cracks in the glass surface, household electrical appliances, wood, and even senior jet gas cylinder can also grow on the plug. Warm wet dust mites xi, mainly grows in the dust, mattresses, pillows, sofa, clothes, food, etc. Mite mites live or die, even the molting or feces, have antigenicity, can cause asthma or urticaria.
Sometimes we might have in domestic bedroom use cosmetics, pesticides, fragrances will cause secondary pollution, the air in the case of outdoor air good frequently and ventilation. Pollen away like smoke, pet hair, lead to air pollution, harmful to human body health has become a consensus, there is no longer here.
In addition to our habits cause pollution, of course, there is a new home decorate pollution reason and the harm to human body caused by air pollution: (, bridal chamber is decorated at least three months period of ventilation, the environmental protection material to decorate need at least 6 months or more will send) to sum up with the following:
1, building materials caused by indoor air pollution. Some cement, brick, lime in raw materials in building materials, such as, itself contains radioactive radium. After being building was completed, the decay of radium, radon (222 rn) and their daughter will be released into the indoor air, to enter the human respiratory tract, is one of the causes of lung cancer. Outdoor air radon content in approximately 10 below the bq/m3, the indoor pollution can be more than dozens of times. The United States caused by radon and its daughter lung cancer is 1 ~ 20000 excess deaths.
2, using the formaldehyde foam insulation (UFFI) of simple houses, activity, can release a large amount of formaldehyde, sometimes can be as high as more than 10 mg/m3. Formaldehyde has obvious stimulation, cross-eyed, larynx, trachea is a big stimulus; In the body can form abnormal condition, cause bronchial asthma and allergy of skin; Can damage the liver, especially people with hepatitis, past medical history, live in UFFI prefabricated houses, easy recurrence of hepatitis. In low concentration formaldehyde for a long time, can cause headache, dizziness, nausea, difficulty breathing, lung function decline, neurasthenia, immune function is also affected. Animal testing can induce the nasopharyngeal carcinoma.
3, many homes use building materials containing asbestos, can send out a asbestos fiber. Asbestos can cause lung cancer, and breast, peritoneal mesothelioma.
4, decorative items and cheap paint, wallpaper and other volatile poisonous gas. Commonly used plastic flooring, floor tile, chemical fibber carpet, plastic wallpaper, adiabatic material, urea - formaldehyde resin adhesive and made of the glue stick made of fiberboard, plywood and other furniture can release a variety of volatile organic compounds and so on, are mainly formaldehyde. A new advanced hotel in shenyang in China, formaldehyde concentration up to 1.11 mg/m3, ordinary after new adornment inside the bedroom can be up to 0.17 mg/m3, decreasing in the future. In addition, some products also can release of benzene, toluene, xylene, CS2, chloroform, trichloroethylene, chlorobenzene and so on more than hundreds kinds of volatile organic compounds. Some of them can damage the liver, kidney, bone marrow, blood, respiratory system, nervous system, immune system, etc., some even can sensitization, cancer.
Saw the introduction of the above, I believe you have on indoor air pollution has a certain value, will think of the importance of purchasing an air purifier.
