What are the causes of indoor environmental pollution

After the decoration, the environmental pollution of indoor decoration is basically a problem that exists in every room after the decoration is completed. Because of this, many people have to wait for a few months after the decoration is completed. The following is my introduction to the causes of indoor environmental pollution. I hope I can help you.

1. Radon pollution

Radon is colorless and tasteless. Even when the radon concentration is very high, people have no feeling about it. Generally, granite, marble, cement and other materials will cause radioactive radon pollution.

2. Formaldehyde pollution

Formaldehyde pollution has great harm and is recognized as a carcinogen, which will cause abnormal immune function, respiratory mucosa, fetal malformation and other hazards. The materials causing formaldehyde pollution include large core board, artificial board, wallpaper, chemical fiber carpet and so on.

3. Ammonia pollution

Ammonia will cause dizziness, dyspnea, vomiting and other hazards. If it is serious, it will reduce human immunity. Especially in winter construction, adding antifreeze containing urea in concrete and sand may cause ammonia pollution.

4. Benzene pollution

Benzene has a strong carcinogen. Inhalation of high concentration of benzene in a short time will cause central nervous system anesthesia symptoms, nausea and coma in severe cases. Some paints, coatings and waterproof materials will release benzene substances.

Formaldehyde: it ranks first. It comes from plates and various adhesives, and its smell is pungent. Inhalation of a small amount of formaldehyde can cause chronic respiratory diseases. Excessive inhalation of formaldehyde can cause asthma.

Benzene: from various paints, carpets, cleaners and solvents. It has a fragrant smell, but it is a deadly substance. If inhaled for a long time, it will cause leukemia. If the inhaler is a pregnant woman, it is likely to cause abortion or birth of a deformed fetus.

Volatile organic compounds: from newly purchased furniture or decoration wallpaper. At least, it will lead to the decline of immunity, dizziness, headache, drowsiness and other adverse reactions. The most important is to damage hematopoietic function.

Ammonia: produced in concrete additives and interior decoration materials. The chemical property of ammonia is easily soluble in water and has strong irritation to eyes, throat and upper respiratory tract. Short term inhalation of too much will lead to chest tightness, cough and tears.

Radon: colorless and tasteless, belonging to natural radioactive gas. It comes from granite, various ceramic tiles and ceramic sanitary ware. An authoritative organization issued a document saying that if the radon content in each cubic meter of space increases by 100 Baker, the risk of lung cancer increases by 16%. Although among all pollution sources, it is the least concerned and least known. But its lethality should not be underestimated.

1. Ventilation method: indoor ventilation can be used to reduce harmful gases in indoor air and reduce the harm of harmful gases to human body. If. The doors and windows are often closed, and the indoor air is not circulating. In this way, not only the content of formaldehyde in the air will increase, but also radon will continue to accumulate, and even reach a very high concentration.

2. Negative ion method: negative ions can mainly purify indoor air and reduce various pollution. Negative ions play a convalescent role in the air and play an auxiliary role in some diseases. It can completely subvert the purification mode of passive adsorption of ordinary air purifiers.

3. Botanical method: some plants can be put indoors to purify the space. For example, Chlorophytum and fortune tree can absorb harmful gases, and these plants can beautify the room. Moreover, the cost is relatively low and the effect is obvious.
