| Abstract |
Of 853 powder metallurgy workers patch-tested with 20 substances from the work environment, 2 men and 38 women were sensitive to nickel. 40% of these had had severe hand eczema, generally within 6-12 months of starting work. 25% of the nickel-sensitive subjects developed cobalt allergy, compared with 5% in the group at large. Nickel sensitivity and eczema appeared to precede the cobalt allergy. Eczema was more severe in individuals with simultaneous sensitivity to nickel and cobalt than to a single metal. 95% of the women allergic to nickel had pierced ear lobes, and the use of earrings containing nickel after piercing is thought to be a major cause of nickel sensitivity. Individuals with a history of jewellery dermatitis should be patch-tested before employment in the cemented-carbide industry. |
