China is a big producer and must be proud of it. But we are also the biggest producer of formaldehyde. Did you know that our own formaldehyde is consumed abroad only for a small part, and the rest is "digested" by our own people? Formaldehyde is the cause of human leukemia, so we understand why there are so many leukemia patients in China, the vast majority of them are children!
Family formaldehyde pollution is everywhere
The main sources of indoor formaldehyde pollution in China are furniture, textiles and daily necessities, indoor cigarettes, gas, incense and so on.
1. Formaldehyde is a kind of industrial raw material with excellent properties. It is used to produce strong adhesives such as urea-formaldehyde resin, phenolic resin and melamine-formaldehyde resin. These adhesives are widely used in wood-based panels, furniture, building decoration and decorative materials. Therefore, furniture made of wood-based panels and decorative materials have become an important source of indoor formaldehyde pollution.
2. Formaldehyde is an important textile finishing agent. In the production of garment fabrics, formaldehyde must be added to the fabrics, especially pure cotton fabrics, in order to achieve the purpose of wrinkle resistance, durability of printing and dyeing, and improvement of hand feel. Therefore, textiles are also an important source of household formaldehyde pollution.
3. Paint, paint, cosmetics, detergents, cigarette smoke, gas stove, incense (including mosquito incense, incense, stick incense), will release a large amount of formaldehyde. It can be said that formaldehyde pollution is ubiquitous in China's modern family life and modern household goods, and long-term release, especially in newly decorated families, formaldehyde emission is more intense.
Formaldehyde has long been banned in developed countries:
In the 1970s and 1980s, formaldehyde-rich urea-formaldehyde resin was also widely used in developed countries. As building decoration materials, they also face serious indoor formaldehyde pollution.
Formaldehyde and disease related research is also a hot issue in Environmental Science in developed countries. However, the indoor formaldehyde problem has been gradually solved. For example, it is forbidden to use urea-formaldehyde resin as building insulation material, and to use environmentally friendly adhesives instead of formaldehyde synthetic resin.
These measures have led to a rapid decline in the enthusiasm of environmental scientists for formaldehyde toxicity research. Since then, few scholars in developed countries have conducted in-depth and systematic studies on the toxicity mechanism of formaldehyde. This has also brought many knowledge gaps and cognitive barriers to researchers in developing countries, making it impossible for them to draw lessons from the problems related to formaldehyde pollution, and thus to bring more information for public and industrial policies to rectify.
