    Abstract:
    Double-focusing sector-field, inductively coupled plasma-mass spectrometry was used for the determination of 71 elements in scalp hair and fingernail samples from an urban population group living in the north-east of Sweden. Samples (n = 114 for hair and n = 96 for nails) were taken from subjects without known occupational exposure to metals. From these results, concentration ranges were calculated and compared with published intervals. Statistical analysis was used to elucidate differences according to sex, age and smoking habit. It was found that significant correlations exist between different elements in hair and nails, as well as between hair and nail concentrations for several elements. Strong positive correlation for Hg, Cd, Pb, Sb and Bi levels between these media confirms that both can be used for exposure assessment for these elements. Several examples on the use of distribution patterns for the rare-earth elements (REE) and of Pb isotope ratios for assessment of exposure are given.
