An atomic absorption spectrophotometry analysis study of zinc, cadimium, lead, copper and mercury in human scalp hair samples of 699 subjects in 3 urban and 4 rural communities gave mean values of 170.33/187.00 ppm, 0.18/0.22 ppm, 8.43/8.62 ppm, 9.81/10.24 ppm and 2.13/1.20 ppm for male and female, respectively. The concentration did not differ significantly regardless ages. However, female was higher than male in overall concentration except that of mercury. The percentile methods was partially applied for a reference values of metals in Korean scalp hair to provide more appropriate data for further comparisons.
