Nickel in nails, hair and plasma from nickel-hypersensitive women
1Royal Danish School of Pharmacy, Department of General Chemistry, Copenhagen, Denmark.
Abstract:
The concentrations of nickel in finger-nails, toe-nails, hair and plasma from 71 nickel-hypersensitive women and 20 non-hypersensitive women were determined. Nickel concentrations in finger-nails were significantly higher than in toe-nails in both the nickel-hypersensitive group and the control group. Nickel-sensitive women had significantly higher levels of nickel in toe-nails, hair and plasma than had control subjects, whereas there was no significant difference in nickel concentration in finger-nails between the two groups. No correlation could be demonstrated between nickel levels in any combination of nails, hair and plasma in the nickel-hypersensitive or in the control group.
