Abstract

A study was carried out during the period of 6 months from April 15 to October 15, 1968 for the purpose of finding out the normal lead level in blood of Korean male adults. The study was made towards 160 males who were convinced through interview that they had never been exposed to lead.
As the results of this study, following conclusions were obtained.
1. The range of normal lead level in blood of Korean male adults was 0∼52μg/100gm of blood, mean 22.2μg/100 gm and standard deviation 10.8μg/100 gm.
2. Blood lead levels in each age group showed as follows: 22.1±11.2μg/100 gm in the second decade, 22.0±10.2μg/100 gm in the third decade, 21.0±9.4μg/100 gm in the forth decade and 30.8±7.4μg/100 gm in the fifth decade. There was no statistical difference in the blood lead levels as the age increases.
3. The lead levels in blood of workers of each group of occupation were as follows: 20.8±9.3μg/100 gm in clerical workers, 24.0±11.5μg/100 gm in electrical workers and 21.4±11.4μg/100 gm in miscellaneous workers. There was no difference in the blood level of lead among workers of each occupation.
4. It seemed to be no correlation between the normal lead level in blood and hemoglobin and blood specific gravity within normal limit of lead in blood.
