手机壳有“毒”？这样挑选更安全

Core Viewpoint - The article highlights the potential health risks associated with low-quality phone cases, emphasizing the importance of selecting safe and reliable products to avoid exposure to harmful substances [1][4]. Health Risks of Low-Quality Phone Cases - Some small workshops may use industrial adhesives to cut costs, leading to excessive levels of formaldehyde and benzene in phone cases [5]. - Certain phone cases are made from recycled plastics, industrial-grade dyes, and may contain illegal cheap additives, which can result in chronic poisoning, developmental abnormalities in children, and increased disease risks with prolonged exposure [8]. Selection Guidelines for Phone Cases - It is recommended to prioritize phone cases made from liquid silicone or thermoplastic polyurethane (TPU), as these materials are typically odorless, soft yet resilient [10]. - Consumers should look for products with 3C certification and those that comply with national standards for phone cases, which usually indicate the material used, such as food-grade silicone. Washing and ventilating new cases for a week before use is advisable [11]. - Avoid purchasing products with strong odors or excessively low prices, as flashy and cheap phone cases often conceal health hazards. Regular replacement of phone cases is suggested to mitigate risks from wear and aging [12][13].
