A worksite survey was conducted in all 38 Finnish electroplating plant
s. All workers (n=163) who worked with nickel plating (bath workers, h
angers and solution makers) were interviewed with a questionnaire abou
t symptoms of nickel dermatitis, hand dermatitis, and about protective
measures, atopy, etc. Patch testing with nickel sulfate was done with
the TRUE Test(TM) method. All the workers, 94 men and 69 women, answe
red the questionnaire. The mean age of women was 41.1 years, and of me
n 43.1 years, respectively. Men had longer occupational exposure to ni
ckel (14 years) than women (10 years). Most workers used protective gl
oves. 35% of women and 30% of men reported present or past hand dermat
osis. 19% reported a history of atopic dermatitis. 15% of women (n=8)
and 4% (n=2) of men had an allergic patch test reaction to nickel sulf
ate. 70% of those with an allergic patch test reaction to nickel repor
ted past or present hand eczema. The prevalence of nickel allergy amon
g the electroplaters was similar to that of patients in patch test cli
nics in Finland. An allergic patch test reaction to nickel sulfate doe
s not necessarily oblige an electroplater to change jobs. (C) Munksgaa
