About formaldehyde poisoning, although the news media has reported many times, there are still some people who don't care. And often do not care about things, to the end it is too late. Indeed, the effect of formaldehyde on us is generally chronic poisoning, it is difficult to find the first time. Let's take a closer look at how formaldehyde poisons us.
Ignoring "environmental capacity" leads to "superimposed pollution"
For the decoration in the room, personal materials can set the formaldehyde emission within the safe range, but all kinds of materials from pollution sources, such as floor, paint and wallpaper, add together in the limited space that the possibility of formaldehyde exceeding the standard is very high, which is the so-called "superimposed pollution".
The "environmental capacity" of an indoor space is fixed and limited. The density of home furnishing materials and household appliances placed in some spaces is too high, which exceeds the limit of environmental capacity, so the test results can not meet the requirements naturally, and the smaller the space, the more obvious.
Plywood, joinery, MDF and particleboard used in interior decoration will produce formaldehyde pollution for many years.
It is understood that "environmental capacity", an environmental protection issue, is also the most representative issue at this stage. Many consumers are immersed in the error of "environmental protection materials, furniture, bedroom environment, some environmental protection". It is more terrible to imagine the harm caused by several pollution superposition.
Taking formaldehyde as an example, suppose that 10 pieces of environmental protection big core boards are used in a room of 100 square meters. Maybe the formaldehyde content in the indoor environment meets the national standard, but if 30 pieces of big core boards are used in this bedroom, the indoor formaldehyde content may exceed the standard and cause pollution.
People want their homes to look luxurious, but the more luxurious the decoration, the more complex the design, the greater the amount of various materials used, and the more pollution sources generated.
So, this is the reason why we choose environmental protection materials, after decoration, formaldehyde and other harmful chemicals still exceed the standard.
"Environmental protection material" = "non toxic and pollution-free"
Environmental protection material refers to the content of harmful substances in the national standards. Some so-called "environmental protection products" actually contain trace formaldehyde and benzene chemicals, but their content is relatively low, in line with national regulations.
Therefore, many consumers fall into a misunderstanding: environmental protection materials are safe and non-toxic!
In addition, because the current requirements of China's standard home furnishing materials are generally lower than those of Europe, the United States and other developed countries, many so-called "green" materials are not really non-toxic and pollution-free in the market, and the release of harmful chemicals will cause certain harm to human body, rather than simply considering "environmental protection" as no problem.
Formaldehyde is also found elsewhere
In fiber products, formaldehyde can make the color of textiles bright, maintain the durability of printing and dyeing, make cotton fabric wrinkle proof, shrink proof, flame retardant, widely used in curtain and other textile industries.
Because formaldehyde can keep the surface color of watery food bright, can increase the toughness and brittleness, improve the taste, and can also be antiseptic. It can be used to soak seafood, fix the shape of seafood, and maintain the color of fish. Therefore, formaldehyde has been widely used in various aquatic products.
Formaldehyde can come from cosmetics, detergents, pesticides, disinfectants, preservatives, inks, paper, etc., and can also come from car seat covers, seat cushions, roof linings and other interior decoration materials, of which the formaldehyde released by new cars is the most prominent.
