The furniture industry is difficult to check the heavy metal content report

“Prepare to buy children's furniture for children. After discovering the implementation of the mandatory national standards for children's furniture, most of the shapes and specifications are in line with the new regulations, but it is difficult to find the 'heavy metal content test report' in the market.” Ms. Sun said. I have carefully studied the new national standard, which imposes strict limits on the content of 10 toxic and hazardous substances including soluble heavy metals such as antimony, arsenic, antimony and selenium. The reporter's investigation found that the metal test report of the furniture market is indeed hard to find. Experts remind consumers to ignore the dangers of heavy metals.

After visiting a number of furniture stores, the reporter found that most of the business presentations were environmental certificates and quality inspection reports, but the reporter did not find any reports on heavy metals. A salesperson said that with these two items, the furniture is in line with national standards and is an environmentally friendly product. A person in charge of a well-known brand furniture in North China said that some furniture uses a plant painting process without adding thinner materials; some furniture even paint-free, using wooden stickers; some furniture uses environmentally friendly paints or water-based paints, these furniture are not at all Contains heavy metals, so no testing is necessary.

Li Hongzhu, an associate researcher at the Tianjin Pharmaceutical Research Institute, 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 powders, common There are talc, titanium dioxide, etc. If there is a problem with these mineral powders, heavy metals will be brought into the paint. Zhang Yuncheng, vice president of Tianjin Furniture Association, pointed out that according to the "Limits of Hazardous Substances in Wood Furniture for Interior Decoration Materials", four heavy metals such as cadmium, chromium, lead and mercury in wood furniture must be within the limited standard range, that is, lead ≤ 90 Mg/kg, cadmium ≤75 mg/kg, chromium ≤60 mg/kg, mercury ≤60 mg/kg. On the basis of the "General Technical Conditions for Children's Furniture", the limit requirements of four kinds of harmful substances are added, namely: 锑 ≤ 60 mg / kg, arsenic ≤ 25 mg / kg, 钡 ≤ 1000 mg / kg, selenium ≤ 500 mg / kg . According to the requirements of relevant national standards, no matter which processing technology is adopted by the manufacturer, the furniture products should be tested for heavy metal content.

The reporter also found that most consumers pay attention to environmental protection when purchasing furniture, but pay more attention to the content of formaldehyde and lead, and do not understand the hazards of heavy metals. Li Hongzhu said that due to the strong concealment of harmful substances such as heavy metals, it is not easy to cause consumers to be vigilant, but the surface coating of furniture may bring heavy metals into the body under the action of human body contact friction or suitable solvent. For example, chronic mercury poisoning mainly causes central nervous system diseases; sputum and arsenic have radioactive damage to the skin, which can cause skin pigmentation and lead to abnormal keratinization; when selenium is excessive, people will get rickets; when sputum is in contact with skin or eyes Can cause a burning sensation. Lead can damage human nerves, hematopoiesis and reproductive system, especially to children and adolescents, which may affect children's growth and development and intellectual development; long-term inhalation of cadmium may impair kidney and lung function; long-term exposure to chromium compounds may cause dermatitis and eczema.

Zhang Yuncheng believes that heavy metal problems are widespread in household items, including furniture, ceramics, and flooring. In addition to furniture manufacturers should strengthen the emphasis on heavy metal testing, the relevant national law enforcement agencies should also strengthen the monitoring of heavy metal content of household goods. Remind consumers to choose products that are brightly colored and have more colors when purchasing furniture. Check carefully whether the quality inspection report of the merchant meets the requirements of “Limited Hazardous Substances in Wood Furniture for Interior Decoration Materials”.
