What are the common indoor air pollutions?

Common indoor air pollution mainly includes:

Harmful volatiles from poor indoor decoration materials, such as formaldehyde, benzene, radon, etc. Formaldehyde is mainly used in boards, such as wood-based panels, sandwich panels, etc.

Formaldehyde can cause cancer when it is seriously exceeded, and it may also lead to fetal malformations. Formaldehyde emissions can take up to three to five years, or even fifteen years. Benzene is found in paints, glues, coatings.

Benzene contamination can easily cause symptoms such as dizziness, nausea, and vomiting in the human body. In addition, benzene can also cause carcinogenesis and cause blood diseases. Radon is a radioactive substance found in building cement and decorative stone.

The harm of radon to the human body is to cause lung cancer, which is the second leading cause of lung cancer after smoking**;

Indoor biological contamination. It mainly includes bacteria, fungi, molds, viruses, dust mites, pollen, pet dander, organic components of organisms, etc.

Indoor biological pollution is very harmful to the human body and can cause various diseases, such as various respiratory diseases, asthma, allergic reactions, etc. Most of the respiratory diseases known to human beings, including colds and pneumonia, are transmitted indoors through air circulation; Smoke, second-hand smoke, carbon dioxide, odor, odor and other self-generated pollution of indoor life. Due to the relatively closed indoor air, the air is not circulated, and the oxygen content is low, which can easily lead to a lack of oxygen in the brain, a decrease in metabolic ability, and a decrease in immunity;

Indoor pollution is okay, that is, there will be some carcinogenic substances in the oil smoke emitted when cooking, and at the same time, he will also have some. Game. Uncomfortable gas production, then there is also indoor smoking, smoking problems, which is difficult to control.

Contamination of building materials. The gypsum board used in modern building decoration breeds bacteria, viruses and other microorganisms; Pollution caused by enclosed buildings. The fully enclosed building isolates the circulation of natural fresh air, and the indoor air is turbid; **Dust build-up in air conditioning ventilation ducts, contamination caused by organisms.

diameter of inhalable particles), formaldehyde content exceeds the standard.

Negative oxygen ions can promote gastric juice secretion, increase appetite, and have a good effect on gastroduodenal ulcer, chronic gastritis, crampy constipation, allergic enteritis, indigestion, etc.

Modern young people suffer from the symptom of "old stomach disease": pain. Presents with dull, tingling, and cramping pains.

Flatulence. Bitter mouth. Patients with gastric problems have a long history of disease, easy to turn yellow, nausea and vomiting.

Eating disorders, vomiting, chest tightness. Staying in a negative oxygen environment for a long time will improve the symptoms.

Indoor pollution sources are mainly manifested in several aspects:

Aldehyde ——— mainly used in plates and binders;

Benzene, xylene——— mainly used in paint;

1. Try to avoid using plywood with high glue content such as large core boards, and use polyamine veneer.

2. Try to avoid the on-site production of paint and adopt the paint-free process.

3. Use environmentally friendly materials to reduce the emission of harmful gases.

4. Minimize the on-site production of wood products and select finished furniture. As for doors, window covers, dumb mouths and heating covers, you can also find a professional manufacturer, produce them in the factory, and get them to the site to install.

5. Try to use environmentally friendly hydroamine board as the base material, because the physical and chemical properties of hydroamine are relatively stable and not easy to deform. In addition, the triamine veneer does not need to be painted and other finishes in the later stage, which also reduces the possibility of surface cracking. In addition, try to do a comprehensive plan before decoration, and determine the style and style of furniture to ensure the smooth progress of the home decoration project.

Indoor air pollution and outdoor air pollution have different characteristics depending on the environment in which they live. Indoor air pollution has the following three characteristics:

1) Cumulative: The indoor environment is a relatively closed space, and one of the characteristics of its pollution formation is cumulative. It usually takes a long time for the pollutant to rise from the time it enters the room to the time it reaches zero when it is discharged from the outside.

All kinds of indoor items, including building decoration materials, furniture, carpets, photocopiers, printers, etc., can release certain chemicals, and if effective measures are not taken, they will gradually accumulate indoors, resulting in an increase in the concentration of pollutants and constituting a hazard to the human body.

2) Long-term Some surveys have shown that people spend most of their time indoors, and even very low concentrations of pollutants can adversely affect human health after long-term effects on the human body.

Therefore, long-term nature is also one of the important characteristics of indoor pollution.

3) Diversity The diversity of indoor air pollution includes both the diversity of pollutant types and the diversity of indoor pollutants**. The pollutants present in the indoor air include biological pollutants, such as bacteria; Chemical pollutants such as formaldehyde, ammonia, benzene, toluene, carbon dioxide, nitrogen oxides, sulfur dioxide, etc.; There are also radioactive contaminants, such as radon and its progeny.

Indoor pollution is basically decoration pollution, furniture pollution, smoking and so on.

Hope, thank you.

Common indoor air pollution is caused by decoration, methane and other harmful gas pollution, as well as because of poor indoor ventilation conditions, some dust in the air in daily life, including some oil smoke and the like, pollution, and some indoor dust pollution.

Common indoor pollution includes the smell of cooking fumes, formaldehyde from furniture, and the smell of fermented garbage in garbage cans.

Indoor air pollutants** are broadly divided into three categories. Harmful factors produced by indoor human activities People carry out physiological metabolism indoors, carry out daily life, work and study activities, which can produce many pollution factors. The main aspects are as follows:

Exhaled breath The main component of exhaled breath is CO2. The average CO2 exhaled per hour per adult is about liters. In addition, ammonia, dimethylamine, diethylamine, diethanol, and methanol can be accompanied by exhalation.

What are the common indoor air pollutions? The common indoor air pollution is mainly formaldehyde, because formaldehyde exists in every corner of the home, so it is necessary to choose a good product to remove formaldehyde.

With the development of industry, pollution is becoming more and more serious. All kinds of cars, factories, etc. have caused a lot of pollution, making the air very turbid, but now the pollution is not only in the outdoors, the indoor air is also polluted, some people may not understand, the indoor space is very small, where is the pollution. In fact, there are still a lot of pollutants, including many aspects.

1) Contaminants excreted from the human body.

In order to maintain normal physiological activities, the human body needs to breathe and metabolize, and the respiratory system not only inhales oxygen and excretes carbon dioxide, but also excretes other turbid gases from the body. The digestive system, surfaces, and sweat glands are also the main parts of the elimination of harmful substances from the body.

2) Pollutants from indoor fuel combustion.

Common indoor fuels mainly include natural gas, petroleum liquefied gas, coal gas, charcoal, etc. The combustion of these fuels will produce pollutants such as carbon monoxide, respirable particulate matter, nitrogen dioxide, sulfur dioxide, etc.

3) Pollutants from cooking fumes.

Cooking fumes contain more than 200 kinds of chemical components, some of which have strong carcinogenic and cytogenic mutagenesis. Usually the stir-fry temperature is above 250, and the food in the hot oil will undergo oxidation, hydrolysis, polymerization, cracking and other reactions at this temperature, and the reaction products may also volatilize with the oil smoke.

4) Pollutants from cigarette smoke.

Cigarette smoke is one of the main causes of indoor air pollution. When someone smokes, non-smokers also inhale particulate matter, carbon monoxide, nitrogen oxides, and many harmful organic matter in it. Among them, 50% of the substances seriously affect physical health.

Formaldehyde, formaldehyde is the main pollutant in the indoor environment, and regular inhalation can cause chronic poisoning.

Formaldehyde mainly comes from particleboard, fiberboard, large core board, plywood, sponge for sofas, sponge mattresses and adhesives for wall and ground decoration. Formaldehyde is recognized as a potential carcinogen in the world, and its toxic hazards are mainly manifested in nervous system and respiratory symptoms, lung damage and central nervous system affected, such as headache, dizziness, dry throat, cough, etc.

Benzene series, in chemistry, benzene is a colorless, special aromatic odor gas, is also a kind of indoor volatile substance.

Benzene is an organic solvent for glue, paint, paint and building materials used in decoration, mild poisoning can cause headache, dizziness, nausea, vomiting and other symptoms, and heavy polluters can also cause irregular heartbeat, shortness of breath, causing different degrees of leukemia.

Common indoor air pollution is mainly formaldehyde pollution after decoration, so it is very important to maintain indoor air circulation.

Generally speaking, common indoor air pollution, such as the smell of decoration, includes the smell of paint, the smell of tobacco by some smokers, and so on.

The various gases discharged, as well as some smells released by various substances themselves, are all polluting to the air.

This common indoor air pollution is formaldehyde left over from the renovation of the house. This baby is the most polluting thing, because formaldehyde will not be absent for a while and a half, so the pollution is serious.

Common indoor air pollution is formaldehyde pollution during decoration, as well as odor pollution.

Common air pollution, such as carbon dioxide pollution, or exhaust smoke, exhaust gas, smog and so on emitted by some factories.

Common indoor pollution is mainly the pollution of some harmful gases such as formaldehyde, as well as the pollution of kitchen fumes.

What are the common indoor air pollution, such as cooking fumes, gas, cigarettes, and many more.

Common indoor air pollution is mainly formaldehyde, with some dust particles.
