Students who love watching Korean dramas summarized three major routines for Korean dramas: car accidents, cancer, and incurability. For most of us, diseases such as leukemia are just a touching scene in TV dramas. But as information spreads faster and faster, we suddenly discovered that so many people are suffering from leukemia, lung cancer and other diseases, and scenes of tragedies in TV series are being played out in real life.
There are many causes of leukemia. At present, one of the most concerned ones is indoor air pollution, and decoration materials are the main cause of indoor air pollution. Adhesives in decoration are , coatings, floors, furniture, etc. will release toxic and harmful substances such as formaldehyde, toluene, TVOC, etc.
Because children spend most of their time indoors, their immune systems are not fully developed and are most affected by pollution. This is why in recent years, there have been more and more news about childhood leukemia. There are many reasons.
I just say that many people may not have any idea. Let's take a look at the bloody figures. These figures and the continuous tragedies around us are shocking.
According to reports, 45% of the 1,800 children with leukemia treated by Harbin First Hospital in the past 10 years had their homes renovated within six months. A physician at Beijing Children's Hospital found that 90% of the homes of children with leukemia had been decorated during six months of diagnosis. Among 1,200 elderly leukemia patients, 54% of their homes had been renovated within six months.
(Qian Qian, Wang Yuqiu. Decoration pollution and human health, Environment and People, 2008, 38)
According to statistics from medical institutions, 40% of elderly cancer patients are closely related to indoor decoration pollution, 90% of children with leukemia have had their homes renovated within six months, and more than 70% of infertile patients have had their homes renovated within 1-2 years. (Lian Chuang. Analysis of the impact of indoor decoration on air quality, Urban Construction Theory Research, Issue 17, 2013)
These cases show that everyone is paying attention in the right direction, and the harm caused by decoration pollution cannot be underestimated.
According to the air quality sampling results of newly-decorated residences released by the China Building Decoration Association, the average formaldehyde exceedance rate is 70%-80%, with the highest value exceeding the national standard by 4.2 times, TVOC The exceedance rate is 75%, and the highest detection value exceeds 5 times the national standard. Indoor air pollution is 2-3 times more serious than outdoor air pollution. In some serious cases, it may even reach more than 100 times. Pollutants that can be detected indoors There are more than 300 kinds of substances, of which more than 20 are carcinogenic substances. 68% of human diseases are related to indoor air, and the main causes of these problems are furniture and interior decoration.

Formaldehyde
Formaldehyde is a colorless, highly irritating gas and one of the main pollutants of indoor air.
Man-made panel furniture, chemical fiber carpets, plastics, coatings, paints, etc. all release formaldehyde.
The release cycle is as long as 3-15 years, which can cause throat discomfort or pain, nausea and vomiting, asthma and even pulmonary edema; long-term exposure can cause nasopharyngeal cancer, colon cancer, miscarriage, Infertility, etc.; can lead to insomnia, lack of concentration, memory loss, etc. ①
On October 27, 2017, the World Health Organization’s International Agency for Research on Cancer published a list of carcinogens that placed formaldehyde in the Class I list of carcinogens. On July 23, 2019, formaldehyde was included in the list of toxic and harmful water pollutants (first batch).
Benzene series
Benzene series compounds include benzene, toluene, ethylbenzene, xylene, etc. The paints and coatings used in the home decoration process all contain benzene series compounds.
Furniture and floors using paint and paint will release benzene series compounds.
Long-term inhalation of benzene can cause aplastic anemia. ②
On October 27, 2017, the World Health Organization’s International Agency for Research on Cancer released a preliminary reference list of carcinogens. Toluene is included in the list of Class 3 carcinogens.
TVOC (Total Volatile Organic Compounds)
Quick-drying paints, coatings, adhesives, and floor and wall decoration materials used in the home decoration process contain more than 300 kinds of volatile organic compounds, of which more than 20 are obviously harmful to the human body.
Paints, coatings, adhesives, etc. release vinyl dichloride, etc.
Can cause dizziness, headache, drowsiness, weakness, chest tightness and other symptoms. ②
Ammonia
Ammonia is a colorless gas that has a strong irritating smell when it reaches a certain concentration.
Antifreeze containing urea is added to the concrete in construction construction, which can slowly release ammonia into the indoor air; in addition, waterproof layers and furniture coatings will also release ammonia.
Prolonged exposure to low concentrations of ammonia can cause laryngitis, hoarseness, pulmonary edema, etc. ②
Decoration pollution is so harmful, why do so many tragedies happen? There are nothing more than the following two points. One is not knowing or understanding; the other is understanding but not paying attention to it. It is not a big deal. Tragedies often happen when one is lucky. Although the cause of leukemia cannot be 100% clear, we can prevent high-risk factors for cancer in the environment.
The most important and simplest thing is to use materials that meet environmental protection standards when decorating, and try to use pollution-free or less-pollution construction techniques. Don't be in a hurry to move in after the decoration is completed. It is better to let it be ventilated and vacant for 3-6 months before moving in.
Although environmentally friendly materials are used, there are still cases where pollutants exceed standards. It is recommended to use special negative ion tiles, a healthy tile that can produce negative ions and purify the air. Once laid, It can continuously generate negative ions 24 hours a day to remove formaldehyde, remove odors, and purify the air, enabling all-day purification., can effectively solve the problem of long-lasting evaporation of toxic gases such as formaldehyde.
The inventor of negative ion ceramic tiles has been focusing on negative ion ceramic tiles for fourteen years to create a more livable indoor environment for thousands of households.
In 2017, it specially became the drafting and compilation unit of the three major standards of "group standard, industry standard and national standard" for negative ion ceramic tiles to provide consumers with healthy and good ceramic tiles.
