镉超标9000多倍，“银”以为美实则“毒”不可言

Core Viewpoint - The article highlights the health risks associated with low-quality jewelry that is falsely marketed as gold or silver-plated, revealing that many such products do not meet the required standards and may contain harmful heavy metals [3][4][5]. Group 1: Product Quality Issues - Many jewelry items marketed as gold or silver-plated do not meet the required thickness standards for precious metal coatings, with 17 out of 21 samples tested failing to meet these standards [4]. - Specific examples include a "silver-plated" bracelet with a silver coating of only 0.24 micrometers, far below the required 2 micrometers, and a "gold-plated" bracelet with a gold coating of only 0.03 micrometers, well below the required 0.5 micrometers [4]. Group 2: Health Risks - Some jewelry items contain hazardous heavy metals, such as cadmium, which can pose significant health risks. One tested pair of earrings labeled as S925 silver was found to have cadmium levels exceeding the standard by over 9000 times [5][6]. - Cadmium is recognized as a highly toxic heavy metal and classified as a Group 1 carcinogen by the International Agency for Research on Cancer [5]. Group 3: Market Regulation and Consumer Awareness - The prevalence of low-quality jewelry in wholesale markets and on e-commerce platforms underscores the urgent need for stricter regulation and oversight of the jewelry market [8]. - Regulatory authorities are urged to enhance supervision and impose penalties on businesses that engage in false advertising and substandard product offerings [8]. - Consumers are advised to exercise caution and prioritize quality and safety over low prices when selecting jewelry [9].
