Recently, the 'Notice on the Results of Quality Supervision and Spot Checks of Furniture Products in 2020' published on the website of the Shenzhen Municipal Market Supervision and Administration Bureau shows that in the second quarter of 2020, the Shenzhen Municipal Market Supervision and Administration Bureau organized and carried out quality supervision and random inspections of furniture products. A total of 170 batches of products sold by 81 companies were randomly checked this time, and 4 batches of unqualified samples were found in the inspection, and the discovery rate of unqualified products was 2.4%. The unqualified items are mainly: formaldehyde emission. According to the requirements of the 'Limits of Hazardous Substances in Finished Furniture and Raw and Auxiliary Materials' (SZJG52-2016) standard, this supervision and spot check has tested five mandatory items such as formaldehyde emission, benzene emission and toluene emission of furniture products. . A total of 4 batches of furniture were found to be unqualified in formaldehyde emission, involving Jinkeer (Shanghai) Bedding Co., Ltd., Hongjiafu Furniture (Shenzhen) Co., Ltd., Shenzhen Mengtiantian Furniture Co., Ltd., and Zhongshan Yili Office Furniture. Co., Ltd. and other (nominal) production units. According to reports, formaldehyde has been identified as a carcinogen by the World Health Organization. Formaldehyde is mainly irritating to the skin and mucous membranes. Direct contact with formaldehyde on the skin can cause allergic dermatitis, pigmentation, and necrosis. Inhalation of high concentrations of formaldehyde can induce bronchial asthma. Frequent inhalation of a small amount of formaldehyde can cause chronic poisoning, mucosal congestion, skin irritation, and allergic dermatitis. At present, my country's current indoor air quality standards stipulate the activity and concentration limits of various indoor pollutants. Among them, the standard value of formaldehyde is 0.10mg/m2. GB/T 26706-2011 'Standard for Brown Fiber Elastic Mattresses for Upholstered Furniture' stipulates that the formaldehyde emission in brown mattresses should not exceed 0.05㎎/㎡.h. According to various formaldehyde detection standards, at present, the methods for detecting formaldehyde in domestic and foreign rooms, textiles and food mainly include spectrophotometry, electrochemical detection method, gas chromatography, liquid chromatography, sensor method, etc. Among them, spectrophotometry is a qualitative and quantitative analysis method established based on the selective absorption of electromagnetic radiation by substances with different molecular structures. For different application fields, the method covers the acetylacetone method, the phenol reagent method, the AHMT method, the magenta-sulfurous acid method, the color-changing acid method, and the catalytic photometric method. In addition, the general public can also contact the relevant formaldehyde testing companies. The formal companies are more professional, so as to prevent the situation that the quality of the instruments is not high and the harm is ignored. At present, there are many formaldehyde testing companies in the testing market. As more and more people pay attention to this hazard, the market will become wider and wider. And if the company has the national CMA qualification, its test data can be used as a legal basis. It is not difficult to see that formaldehyde is a carcinogenic gas that is extremely harmful to the human body, and everyone must pay attention. It is believed that in the future, there will be more and more standard formaldehyde gas detection, and the formaldehyde detection instrument will have a wider development space to match it.
