Indoor decoration is very important for “environmental protectionâ€
With the development of science and technology, the industry has become more and more developed, and people's perspective on aesthetics has also improved. Everyone will choose some bright colors when they are decorating, but everyone will often ignore the latent crisis here! Summer is the peak period of indoor air pollution. As room temperature increases, the amount of harmful gases released from various building materials and furniture increases. According to relevant information, when the indoor temperature is 30 degrees Celsius, the indoor harmful gas release is the highest. The boiling point of formaldehyde is 19 degrees Celsius, and the houses that feel uncontaminated in the autumn and winter seasons will feel a lot of smell in the summer.
The survey confirmed that in modern cities, indoor air pollution is many times higher than outdoor, and more importantly, more than 80% of the urban population spends more than 70% of the time indoors, while children, pregnant women and chronic patients, because Staying indoors is longer than other people, and the harm from indoor environmental pollution is even more significant. Especially children, they are more vulnerable to indoor air pollution than adults. On the one hand, the child's body is growing and developing. The amount of breathing is nearly 50% higher than that of adults. On the other hand, children spend 80% of their time indoors. The World Health Organization announced that 100,000 people worldwide die of asthma every year because of indoor air pollution, and 35% of them are children. The prevalence of asthma in children in China is 2% to 5%, of which 85% of children are aged. Under 5 years old.
Formaldehyde has been identified as a class of carcinogens by the World Health Organization, and there is a causal relationship between formaldehyde and leukemia. At present, formaldehyde is the main pollutant in newly renovated homes in China. Children are at high risk of indoor environmental pollution. The relationship between formaldehyde pollution and childhood leukemia should attract the attention of the whole society.
In 2004, the American Institute for Occupational Safety and Health surveyed 11,039 workers who had worked in the formaldehyde-excessive environment for more than three months, and found that 15 people died of leukemia. The National Cancer Institute surveyed 25019 workers and found 69. The name died of leukemia, the proportion of death is slightly higher than that of the general population, and the relative risk increases with the increase of formaldehyde concentration. Therefore, it is speculated that formaldehyde may be related to the occurrence of leukemia, and it is believed that formaldehyde may cause leukemia.
According to the epidemiological statistics released in China, the natural incidence of leukemia in China is relatively high. About 40,000 leukemia patients are newly added each year, 50% of which are children, and most of them are children between 2 and 7 years old. Home decoration leads to indoor environmental pollution and is considered to be the main cause of the increase in urban leukemia. In the 2001 Beijing Children's Hospital, more than 90% of children with urban leukemia were renovated in six months. In 2004, Shenzhen Children's Hospital and related departments conducted a survey on the family living environment of newly-increased children with leukemia, and found that 90% of small patients had been renovated within half a year.
Although, in these epidemiological investigations, there is still a lack of research on the relationship between formaldehyde pollution and childhood leukemia. Because children have hematological characteristics different from adults, such as children are growing up, hematopoietic function is unstable, and hematopoietic reserve is poor; children's hematopoietic organs are susceptible to infection and are prone to nutritional deficiencies. Therefore, the effect of excessive formaldehyde on children's hematopoietic organs may be more serious than adults. Indoor environmental pollution caused by improper decoration is a significant cause of the increase in pediatric leukemia patients in recent years. Therefore, in order to complete the family, everyone should pay more attention when choosing decorative materials!
