    Abstract:
    The aim of this study was to assess the iron, zinc and copper status of elderly people using hair trace element levels determined by using atomic absorption spectrophotometry (AAS). The samples of hair were taken in May-June 1999 from 73 people aged 75-80 years (50 men and 23 women) living in Warsaw district. The mean content of iron was 17.32 +/- 12.38 micrograms/g dry weight, zinc 176.44 +/- 64.33 micrograms/g d.w. and copper 11.25 +/- 6.32 micrograms/g d.w. Although these values were in range of reference intervals almost 40% of population had iron and zinc level below them, and for copper the result was even worse (50% of the elderly people). No significant differences between trace element content in hair of male and female have been observed. However it has revealed a trend that female hair contained less iron and more zinc than male hair. The mean copper level was similar for both sexes. It has been found that subject who had not excluded any food products from their diets had higher hair iron contents than those with some dietetic restrictions.
