儿童电话手表辐射及表带致癌物的检测研究

摘要

Through analyzing the structure of seven best-selling children phone watches,the values of the electromagnetic radiation SAR and the carcinogenic polycyclic aromatic hydrocarbons (PAHs) in the watchband were tested.The results showed that among these 7 children watch phone,only the SAR value of No.1 sample was 2.12 w/kg,which was beyond the SAR values exposure limit of 2.0 w/kg regulated by GB 21288 -2007.Polycyclic aromatic hydrocarbons (PAHs) of No.5 and No.6 samples were excessive,when the limit was evaluated in terms of class 1,which regulates that the total amount of 18 polycyclic aromatic hydrocarbons (PAHs) should be less than 1mg/kg.There is no clear standard for the detection of PAHs in our country,and we hope that the technical standards for children smartwatches can be implemented as soon as possible.%通过对热销的7款儿童电话手表从结构上分析,测试了电磁辐射SAR值和表带上致癌物质多环芳烃(PAHs)值.结果表明:这7款儿童电话手表,只有1号样品SAR值为2.12瓦特/千克,超出了GB21288-2007标准规定SAR值暴露限值不超过2.0瓦特/千克的要求;5号样品、6号样品的多环芳烃(PAHs)是超标的,限值讨论了用第1类来评判18种多环芳烃(PAHs)总量小于1毫克/千克.我们国家目前对多环芳烃(PAHs)检测没有明确的标准,希望《儿童智能手表技术标准》能早日出台实施,生产企业科技创新,相关部门加强监管,消费者也要在该产品质量上提高安全意识.
