Abstract

Background: Nickel and cobalt release from tools has recently been evidenced in German hairdressing salons. Comparable data were not available for German barbershops.

Objectives: Screening of tools for nickel and cobalt release.

Methods/materials: One hundred and forty-one tools were tested in six barbershops located in Lower Saxony, Germany. A nickel spot test (reagent: dimethylglyoxime [CAS no. 95-45-4]) and a cobalt spot test (reagent: nitroso-r salt [disodium-1-nitroso-2-naphthol-3,6-disulphonate; CAS no. 525-05-03]) were used.

Results: 35 of 141 tools overall (24.8%) released nickel and 3 of 141 tools overall (2.1%) released cobalt. Nickel release was found in 10 of 57 hair clippers, 9 of 13 tweezers, 8 of 11 sectioning clips, 3 of 14 straight shavers, 2 of 32 scissors, 2 of 4 tail combs and 1 of 2 shaving brushes. Cobalt release was detected in 2 of 14 straight shavers and 1 of 11 sectioning clips.

Conclusions: Tools in German barbershops have been identified as occupational sources of nickel and cobalt exposure. Nickel release was observed more frequently. Therefore, it is recommended that compliance with the EU nickel regulation is observed more strictly. In addition, the importance of measures to protect the skin at work should be communicated to barbers, e.g., within health pedagogical measures.

德国理发店美发工具中镍和钴的释放。

背景：最近在德国的美发沙龙中发现了从工具中释放镍和钴的证据。没有德国理发店的可比数据。目的：筛选镍钴释放工具。方法/材料：在德国下萨克森州的6家理发店对141种工具进行了测试。镍斑点试验(试剂：二甲基乙氧肟[CAS号]；95-45-4])和钴斑点试验(试剂：亚硝基盐[二钠-1-亚硝基-2-萘酚-3,6-二磺酸盐；[525-05-03])。结果：141个工具中有35个（24.8%）释放镍，141个工具中有3个（2.1%）释放钴。57个理发器中有10个、13个镊子中有9个、11个切片夹中有8个、14个直刮器中有3个、32个剪刀中有2个、4个尾梳中有2个、2个剃须刷中有1个发现镍释放。在14个直剃须刀中的2个和11个切片夹中的1个中检测到钴释放。结论：德国理发店的工具已被确定为镍和钴暴露的职业来源。镍的释放更为频繁。因此，建议更严格地遵守欧盟镍法规。此外，应向理发师宣传工作中保护皮肤措施的重要性，例如在卫生教学措施中。

期刊介绍： Contact Dermatitis is designed primarily as a journal for clinicians who are interested in various aspects of environmental dermatitis. This includes both allergic and irritant (toxic) types of contact dermatitis, occupational (industrial) dermatitis and consumers" dermatitis from such products as cosmetics and toiletries. The journal aims at promoting and maintaining communication among dermatologists, industrial physicians, allergists and clinical immunologists, as well as chemists and research workers involved in industry and the production of consumer goods. Papers are invited on clinical observations, diagnosis and methods of investigation of patients, therapeutic measures, organisation and legislation relating to the control of occupational and consumers".
