The metal test report in the furniture market is hard to find. Experts remind consumers not to ignore the dangers of heavy metals. "Prepare to buy children's furniture for children, and found that after the implementation of the new mandatory national standards for children's furniture , most of the appearance and specifications meet the new regulations, but it is difficult to find a 'heavy metal content test report' in the market." Ms. Sun said I have carefully studied the new national standard myself, which has imposed strict restrictions on the content of 10 toxic and hazardous substances including antimony, arsenic, barium, selenium and other soluble heavy metals. A reporter's investigation found that the metal test report in the furniture market is really hard to find. Experts remind consumers that they should not ignore the hazards of heavy metals. Heavy metals in furniture are harmful When the furniture purchase, most consumers really pay attention to environmental issues, but more attention to the content of formaldehyde and lead, do not understand the hazards of heavy metals. Li Hongzhu, an associate researcher at Tianjin Pharmaceutical Research Institute, said that due to the high concealment of harmful substances such as heavy metals, it is not easy to cause consumers to be vigilant, but furniture surface coatings may be subject to heavy metals under human contact friction or suitable solvents. Bring into the body. For example, chronic mercury poisoning mainly causes central nervous system diseases; antimony and arsenic have radioactive damage to the skin, which can cause skin pigmentation and lead to abnormal keratinization; people with selenium overdose will suffer from staggering disease; when barium contacts the skin or eyes Can cause a burning sensation. Lead can damage the human nervous, hematopoietic and reproductive systems, especially to 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 can easily cause dermatitis and eczema. Zhang Yuncheng, deputy chairman of the Tianjin Furniture Association, believes that heavy metal problems are widespread in household items, including furniture, ceramics, and floors. In addition to furniture manufacturers should pay more attention to the detection of heavy metals, the relevant national law enforcement agencies should also strengthen the monitoring of heavy metals in household items. Remind consumers to try not to choose products with bright colors and more colors when buying furniture, and carefully check whether the merchant's quality inspection report meets the requirements of "Limits of Harmful Substances in Wood Furniture for Interior Decoration Materials". 　  Heavy metal testing for furniture is hard to find     In the furniture store , most of the businesses present environmental protection certificates and quality inspection reports, but there are no reports on heavy metals. A furniture salesperson said that with these two items, the furniture complies with national standards and is an environmentally friendly product. A person in charge of a well-known brand of furniture in North China told reporters that some furniture uses a plant spray paint process without adding thinners; some furniture is even paint-free and uses wooden stickers; some furniture uses environmentally friendly paint or water-based paint. It does not contain heavy metals, so no testing is necessary. 　　 Do furniture products use environmentally friendly paints or paint-free furniture as described by businesses? Are they free of heavy metals? In this regard, Li Hongzhu said that the heavy metals in furniture are mainly derived from the pigment coating on the surface of the product. Even water-based paints may contain heavy metals, which may come from the filler used in the production of water-based paints-mineral powder, common talc powder, Titanium dioxide, etc. If these mineral powders have problems, they will bring heavy metals into the paint. Zhang Yuncheng pointed out that in accordance with the "Limiting of Harmful Substances in Wood Furniture for Interior Decoration Materials", the four heavy metals of cadmium, chromium, lead and mercury in wooden furniture must be within the limits, that is, lead ≤90 mg / kg, cadmium ≤75 Mg / kg, chromium ≤60 mg / kg, mercury ≤60 mg / kg. On the basis of "General Technical Conditions for Children's Furniture", the limit requirements for 4 kinds of harmful substances are added, namely: antimony ≤60 mg / kg, arsenic ≤25 mg / kg, barium ≤1000 mg / kg, selenium ≤500 mg / kg . According to the relevant national standards, no matter which processing technology the manufacturer uses, furniture products should be tested for heavy metal content.
