[China paint information] "Prepare to buy children's furniture for children, and find that the new children's furniture is mandatory by the state. After the implementation of the standards for several important factors affecting the accuracy of microcomputer controlled material testing machines, most of the appearance, specifications and other aspects comply with the new regulations, but it is difficult to find 'heavy metal content detection report' in the market." Ms. sun, a citizen, said that she had carefully studied the new national standard, which imposed strict restrictions on the content of 10 toxic and harmful substances, including soluble heavy metals such as antimony, arsenic, barium and selenium. The survey found that the metal inspection report in the furniture market is indeed hard to find. Experts remind consumers not to ignore the harm of heavy metals

when visiting several furniture stores, it was found that most of the merchants presented environmental protection certificates and quality inspection reports, but no heavy metal detection reports were found. A salesperson said that with these two items, furniture meets national standards and is an environmental protection product. The person in charge of a well-known brand furniture in North China said that some furniture uses plant spray painting technology without adding thinner; Some furniture is even paint free, using wooden stickers; Some furniture uses environmental protection paint or water-based paint. These furniture do not contain heavy metals at all, so there is no need to test

Li Hongzhu, an associate researcher of Tianjin Pharmaceutical Research Institute, said that the heavy metals in furniture mainly come from the pigment coating on the product surface. Even water-based paint may contain heavy metals, which may come from the filler used in the production of water-based paint - mineral powder. Talc powder and titanium dioxide are common in the maintenance of universal tensile testing machine system. If these mineral powders have problems, they will bring heavy metals into the paint. Zhang Yuncheng, vice president of Tianjin Furniture Association, pointed out that according to the "limit of harmful substances in indoor decoration materials wood furniture", the four heavy metals of cadmium, chromium, lead and mercury in wood furniture must be within the limit standard, that is, lead ≤ 90 mg/kg, cadmium ≤ 75 mg/kg, chromium ≤ 60 mg/kg, mercury ≤ 60 mg/kg. On this basis, the general technical conditions for children's furniture has added the limit requirements for four harmful substances, namely: Antimony ≤ 6 requires subversive testing equipment 0 mg/kg, arsenic ≤ 25 mg/kg, barium ≤ 1000 mg/kg, selenium ≤ 500 mg/kg. According to relevant national standards, furniture products should be tested for heavy metal content regardless of the processing technology adopted by the manufacturer

it is found that most consumers do pay attention to environmental protection when purchasing furniture, but they pay more attention to the content of formaldehyde and lead, and the assembly of parts on the whole vehicle, and do not understand the harm of heavy metals. Li Hongzhu said that due to the strong concealment of the harm of harmful substances such as heavy metals, it is not easy to arouse the vigilance of consumers, but the surface coating of furniture may bring heavy metals into the body under the action of human contact friction or suitable solvents. For example, chronic mercury poisoning will mainly cause central nervous system diseases; Antimony and arsenic have radioactive damage to the skin, which will make the skin pigmentation and lead to abnormal keratinization; When selenium is excessive, people will get staggering disease; Barium can cause burning sensation when it comes into contact with skin or eyes. Lead can damage human nervous, hematopoietic and reproductive systems, especially children and adolescents, and may affect children's growth and intellectual development; Long term inhalation of cadmium can damage kidney and lung function; Long term exposure to chromium compounds is easy to cause dermatitis and eczema

Zhang Yuncheng believes that the problem of heavy metals widely exists in household goods, including furniture, ceramics, floors, etc. In addition to furniture manufacturers should pay more attention to the detection of heavy metals, relevant national law enforcement departments should also strengthen the monitoring of heavy metal content in household goods. Remind consumers to try not to choose products with bright colors and more color combinations when purchasing furniture, and carefully check whether the quality inspection report of the merchant meets the requirements of the limit of harmful substances in indoor decoration materials and wooden furniture
