Abstract: Some papers reported that the pH of external environment had great influence on the adsorption and elution of the elements on human hair.But so far, there haven't any reports on human hair pH and its relation with elemental contents of human hair. The authors established a measurement method of hair pH which was easy to be used and had satisfactory accuracy and reproducibility. 131 cases of hair samples were investigated in 1988 and 1989. The hair pH X±SD in 1988 were: children 3.92±0.24(n=20); adult males 5.98±0.84 (28); and adult females 7.05±0.50(24). The results in 1989 showed: children 3.94±0.54 (36);adult males 5.60±0.93(13); adult females 6.78±0.16(10).Therefore, it could be concluded that human hair pH was significantly different between children and adults (p0.001), adult males and females (p0.001)
