Normals range of mercury contents in hair of young Korean adults and its relationship with urinary mercury excretion were studied with 70 healthy male young adults and 20 male children living in Seoul city, who had no obvious evidence of either occupational mercury exposure or therapeutic use of mercurial agents. Mercury analysis was made by means of dithizone colorimetric method with an average coefficient of variation of 29.3%. 1. Mercury contents in hair of the normal male young adults was log-normally distributed, and those of normal children was well fitted to both normal and logarithmicnormal distributions. 2. Geometric means of mercury contents in hair of normal male young adults was 1.45㎍/g(log^-1 0.16㎍/g) and its standard deviation was ±1.70㎍/g(log^-1 0.23㎍/g) with 95% confidence interval of from 0.42㎍/g to 4.93㎍/g. 3. Geometric means of mercury contents in hair of normal children was 2.37㎍/g(log^-1 0.38㎍/g) and its standard deviation 1.36㎍/g(log^-1 0.13㎍/g). 4. Due to the wider variability of measurements of mercury in hair, no difference was found in mercury contents in hair between indiciduals and between measurements. 5. Mercury contents in hair of the normal male young adults showed relationships of logarithmic, exponential and power functions with mercury excretions in urine expressed in terms of ㎍ of mercury per liter of urine.
