Nickel release from white gold discs stored at room temperature for I week in synthetic sweat was analyzed. The nickel content of the discs was 2–15%. The nickel release from the discs was 0.09–0.82μg. Rhodium plating reduced the nickel release to 0.04–0.54 μg 18 nickel‐sensitive women were patch tested with the while gold discs and all showed at least 1 positive patch test reaction. All the white gold discs gave a negative dimethylglyoxime test.

    Nickel allergy: analysis of metal clothing objects and patch testing to metal samples
    TLDR
    Good tolerance will not be obtained that appropriate regulations will prohibit the use of nickel in the manufacture of clothing objects, and surface‐plating and anticorrosive techniques, as well as the results in nickel‐sensitive subjects, are described and discussed. Expand
    Skin contact with gold and gold alloys
    TLDR
    There is no positive and unequivocal evidence of the ability of metals lo mark uncontaminated skin so rapidly that it is possible to write upon it. Expand
    Contact dermatitis from nickel: an investigation of its sources
    TLDR
    Patch tests with the GEIDC standard series of allergens provide support for the substitution of nickel in imitation jewelry with metals such as palladium or bronze. Expand
    Nickel release from metals, and a case of allergic contact dermatitis from stainless steel
    TLDR
    Although the DMG test can be used as a first line test for determining nickel release, some DMG‐negative metal materials probably induce nickel sensitization, and should by no means be advertised as safe in this respect. Expand
    Occupational allergic contact dermatitis caused by rhodium solutions
    TLDR
    Rhodium plating renders the surface of metals hard and resistant to tarnishing, and because of its colour (very similar to silver) and high reflecting capacity, it is used for optical instruments, jewellery, dental prostheses, and decorations. Expand
    Allergic contact dermatitis to nickel: bioavailability from consumer products and provocation threshold.
    TLDR
    Plasma was the most effective solution for removing available nickel from earrings, a possible explanation for the frequent induction of sensitization by ear piercing. Expand
    Contact sensitization to nickel from rhodium‐plated ‘nickel‐free’ earrings
    TLDR
    A nonatopic 36-year-old-woman presented with intense inflammation of the earlobes, characterized by prominent oedema, erythema, exudation and pruritus, and noted that a blackish patina was released onto the skin from contact with the earrings. Expand
    Nickel and cobalt allergy before and after nickel regulation – evaluation of a public health intervention
    Over the 20th century, the frequent use of nickel in consumer products resulted in an increasing prevalence of nickel allergy. Risk items included suspenders in the 1950s–1960s; buttons, zippers and… Expand

    TLDR
    It is concluded that most cases of nickel allergy/nickel dermatitis are preventable without interfering with the quality of life or imposing economic costs to society. Expand
    Nickel release from ear piercing kits and earrings
    TLDR
    Neither gold nor silver plating prevented the nickel release and the most sensitive women showed eczematous reactions to studs/clasps releasing nickel down to 0.05 μg, and the dimethylglyoxime test was positive only when more than 10 μg Ni was released. Expand

    TLDR
    Even though the stainless steel screw contained 14% nickel, this nickel is so firmly bound physically in the alloy, that body fluids or perspiration cannot "leach" out the nickel to make it available to produce an allergic reaction. Expand
