Economic development of Korea brought rapid progress and expansion of her industries. Accordingly, number of workers who have been exposed to hazardous metals are increasing. For better understanding the significance of on the job human metal pollution, a total of 22 solderers among autoworkers and 28 controls among medical ;students was purposively selected as samples of the study. From their blood, concentrati6ns of cadmium and lead were measured with atomic absorption spectrophotometer, and to compare with statistical indices of controls those of solderers were sumarized as follows.
1. Each frequency distribution of cadmium and lead concentration,dn blood of solderers was more positively skewed showing non-Gausian distribution.
2. Interindividual variation of lead concentration in blood of solderers was markedly revealed.
3. Each mean of cadmium and lead concentration in blood of sol0rers was higher than that of controls (Cd; p<0. 01, Pb;p<0.01).
4. Relative ratio of cadmium concentration in blood of solderer8 to that of controls was 1.36 by arithmatic mean and 1.39 by geometric mean.
Relative ratio of lead concentration in blood of solderers to that of controls was 1.SS by arithmatic mean and 1.30 by geometric mean.
5. It was shown that concentration of lead is slightly correlated with that of cadmium both in solderers and controls (solderers; PG0.1, controls: p<(,,.1)
