Renovation of child leukemia
After entering the summer, many parents found that children who stayed in the room for a long time loved to sneeze and sneeze. They also had some inexplicable erythema and lumps. Many parents thought it was due to a mosquito bite or a lice. According to experts, this is actually an allergic reaction caused by excessive indoor formaldehyde caused by house decoration, and even some early symptoms of childhood leukemia.
According to the published epidemiological statistics, the natural incidence of leukemia in China is 3/10 million people. About 40,000 leukemia patients are newly added each year, 50% of which are children, and the majority are children aged 2 to 7 years. In many children, most of them are acute lymphocytic leukemia. The cause of this leukemia is caused by formaldehyde and other highly toxic chemical pollutants in indoor air.
All signs indicate that decoration pollution is the culprit of childhood leukemia. Among children with leukemia, nearly 90% of the children have been renovated in the short to medium term, and many children are still "decorated" at home.
Indoor air pollution caused by improper decoration is one of the reasons for the significant increase in children with leukemia in recent years. Formaldehyde used in decoration materials is an important cause of childhood leukemia. On June 15, 2004, the World Health Organization released the No. 153 announcement, which cracked the suspicion and controversy over the high incidence of childhood leukemia. According to the announcement of the World Health Organization, formaldehyde, a highly toxic contaminant in interior decoration materials, can cause nasopharyngeal cancer, sinus cancer, and leukemia.
Formaldehyde exceeds the standard wounding invisible
Decoration pollution is fiercer than tigers, formaldehyde hurts people invisible. Formaldehyde, also known as aldehydes, is an irritant gas emitted from the decoration materials. With continuous volatilization characteristics, the volatilization cycle lasts for 3-8 years, and the newly decorated or renovated interior has a high volatility period within 3 years. Summer hot weather and winter feeding seasons are usually the peak period of formaldehyde emission, which is 20% to 30% higher than usual.
Formaldehyde is present in a variety of interior decoration materials, such as core boards, door frames, furniture, curtains, cabinets, laminate floors, etc., and is also present in adhesives, coatings, and paints. Annual production of formaldehyde in China is about 3.2 million tons, of which about 1 million tons is used in various decorative building materials.
As a relatively highly toxic substance, formaldehyde ranks second in the priority list of toxic chemicals in China. The high formaldehyde concentration in the living room has obvious irritating odors, which can lead to tearing, dizziness, headache, fatigue, blurred vision and other symptoms. The examination shows that the conjunctiva and pharyngeal are congested, and some patients are auscultated with breath sounds. Heavier persons may have persistent cough, hoarseness, chest pain, and difficulty breathing. This feature is particularly evident in newly renovated houses.
The problem of decoration pollution in China originated in the 1990s. According to a survey conducted by the China Association of Interior Decoration, 80% of the households that have been decorated in urban China have excessive formaldehyde. The problem of formaldehyde pollution exists not only in China but also in Japan, the United States, and Europe. It is a worldwide problem. According to relevant experts, following the "smoke type" and "chemical smog type" pollution, modern people are entering the third generation pollution period marked by "indoor decoration pollution."
After entering the temperature increase in April, many renovated houses have a noticeable odor. If you stay there for a long time, you may feel dizziness, chest tightness, itchy throat, or a feeling of restlessness. Many people think that it is caused by high temperatures. Experts pointed out that, in fact, the adverse reactions caused by excessive formaldehyde caused by house decoration.
