Nickel and Cobalt Release From Hairdressing Tools in German Barbershops.
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.
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".
