The use of nickel-containing stabilizers is decreasing in the marketplace, particularly in North America, due to potential toxicity concerns. In Europe, nickel continues to be used in agricultural film applications. 

Many reports of allergy to nickel continue to appear, from sources including orthodontic prostheses [88 ], mobile phones [89 ], intracardiac metal devices [90, 91 ], and musical instruments [92 ]. In an unusual case, type 1 and type TV contact hypersensitivity reactions to nickel occurred in a 38-year-old woman, who developed... 

To provide Ihc best coniact to the tcnninals rf silver oxide batteries, it is recommended that the deviee contacts be made d" a spring material such as phosphor bronze or beryllium copper, which will maintain a contact force cf at least 50g for an extended period of time. The contacts should be plated widi about 50.8 pm nickel (continuous)followed by a minimum of 5.08 um gold The reliability d" the contact can be further increased ty subdividing the main contact member into two. three or more individual points or prongs sudt as the tines of a fork...
