Despite the political intention to limit nickel allergy and dermatitis in Europeans, nickel allergy remains frequent. There are several explanations for the persistence of nickel allergy and dermatitis, including the increasing use of mobile phones. Before regulation of nickel release from mobile phones, we showed that eight (19.5%) of 41 mobile phones marketed in Denmark between 2003 and 2007 released nickel in concentrations that may result in nickel allergy and dermatitis. In 2009, the EU Nickel Directive was revised to include nickel-releasing mobile phones.
To investigate the proportion of mobile phones sold in Denmark that release nickel after regulation.
Metallic parts from 50 randomly selected mobile phones currently for sale in Denmark were tested for nickel release by use of the dimethylglyoxime (DMG)-nickel spot test.
Nine (18%) phones showed at least one positive DMG test reaction and two phones had more than one DMG test-positive spot.
Apparently, the proportion of mobile phones with significant nickel release remains unchanged, despite the 2009 revision of the EU Nickel Directive. We encourage manufacturers to measure nickel release from metallic components used in the assembly of mobile phones to ensure safe products.
尽管有将镍过敏和镍性皮炎限制在欧洲人群中的政治意愿，但镍过敏仍然很常见。镍过敏和镍性皮炎持续存在的原因有几个，包括手机使用量的增加。在对手机释放镍的情况进行监管之前，我们发现丹麦市场上 2003 年至 2007 年间销售的 41 款手机中有 8 款（19.5%）镍释放浓度可能导致镍过敏和镍性皮炎。2009 年，欧盟修订了《镍指令》，将释放镍的手机纳入其中。
调查丹麦市场上销售的手机在监管后释放镍的比例。
使用二甲基乙二醛（DMG）-镍斑点试验对丹麦目前市场上随机抽取的 50 款手机的金属部件进行镍释放试验。
有 9 款（18%）手机至少有一个 DMG 试验阳性反应，有 2 款手机有超过一个 DMG 试验阳性点。
尽管欧盟 2009 年修订了《镍指令》，但具有显著镍释放的手机比例似乎并未改变。我们鼓励制造商测量用于组装手机的金属部件的镍释放情况，以确保产品安全。
