The harm of formaldehyde to the human body
 Time: 2013-04-26   CLikc:

At present, formaldehyde has become synonymous with chemical release substances. It is a common indoor air stain with a pungent odor at high concentrations, which can cause burning or itching of the eyes and respiratory tract. Some people who are sensitive to formaldehyde gas, even if the concentration of released gas is as low as 0.05 milligrams per kilogram, can cause adverse reactions in the body. This concentration is only half of the current international standard of 0.1 mg per kilogram. Prolonged exposure to formaldehyde can cause allergies, sore throats, headaches, and even nasal cancer. Therefore, international research cancer organizations have classified formaldehyde as a substance that may cause cancer to humans.


Normally, the indoor formaldehyde concentration is higher than the outdoor because there is a lot of formaldehyde source in the room. One is pressed wood products made of formaldehyde resin, such as particle board, medium density fiberboard, plywood and other pressed wood products. Because such products use formaldehyde resin as the adhesive for the material, the formaldehyde can continue to dissipate and release from the material for several years after the product is manufactured for several years.


In recent years, with the concern for environmental quality and the awareness of self-health protection, the state's control and regulation of the release of harmful substances in the environment has become increasingly apparent.


Many countries have formulated comprehensive countermeasures and solutions around people's living environment and human health issues. They have clearly put forward the concept of healthy housing and practice it.


For example, the United States has focused on the development of a number of codes and standards for indoor and outdoor space environments to guide the planning and design of residential areas. For example, Japan's "environmental symbiotic housing" combines the consideration of the global environment, protects the global environment, protects the surrounding environment, and the friendly exchanges between people and nature, and strives to create a healthy living environment suitable for human habitation.


Of course, the measures taken by different countries are different. Regarding healthy homes, the World Health Organization also has a comprehensive nine standards, one of which has specific international standards for the decoration materials and indoor air environment.


China is a big exporter of wooden furniture. In the international market, the price of wooden products is determined by the level of formaldehyde itself. In the European and American markets, the E1 class represents high-standard, high-quality wooden products. Some high-end brands in Europe also have high standards of E0 products. In order to show customers higher technical standards and quality, the local government only enforces E1. Japan is a major importer of wood products, and its national mandatory requirement is E0 grade with very low formaldehyde content.


In order to determine that the wooden products submitted by the customer meet the national or export limit requirements, wooden raw materials, such as uncoated particleboard, medium-density panels and splints; semi-finished products, such as coated particleboard and composite panels, etc. Both need to use the corresponding standard test methods for testing.


According to current product and regulatory requirements for formaldehyde gas, Jinan Hainat Technology Co., Ltd. can provide a formaldehyde detector to help you control the formaldehyde in the product without affecting the health of consumers.


The so-called E0 standard refers to the enterprise's internal control health implementation standards set by the company in accordance with the international high-quality standards of similar products, that is, the average amount of formaldehyde emission is less than 0.5mg/L. Currently, only a few countries such as Japan and Finland implement similar standards. In China's current national standards for drinking water, the formaldehyde residue limit is 0.9 mg/L. Formaldehyde, chemical formula HCHO, is a colorless and strongly pungent odor. Its 40% aqueous solution is called formalin and is a preservative. Formaldehyde is highly volatile at room temperature and accelerates with increasing temperature. Formaldehyde is a highly toxic substance, and formaldehyde ranks second in the list of chemicals with priority control of toxic chemicals in China. Formaldehyde has been identified by the World Health Organization as a carcinogenic and teratogenic substance.
