For the purpose of identifying mercury, lead, cadmium, copper and magnesium in blood and clarifing their relationship, studies were made of 47 healthy male adults from 20 to 40 years of age living in Gwang-ju city, Chollanam Do, who had no obvious evidence of either exposure to heavy metals or therapeutic use of them from June to August 1983.
From their blood, levels of mercury were measured with the mercury analysis system and levels of the other metals were measured with the atomic absorption spectrophotometer.
The results obtained from this study are as follows;
1. The mean of mercury level in blood was 22.16±10.36,ug/100㎖ and the range was 7.1-47.0㎍/100㎖
2. The mean of lead level in blood was 23.04±9.60㎍/100㎖ and the range was 5.4-46.5㎍/ 100㎖.
3. The mean of cadmium level in blood was 1.75±1.14㎍/100㎖ and the range was 0.00-4.25㎍/100㎖.
4. The mean of copper level in blood was 245.6±145.9㎍/100㎖ and the range was 67.5-635.5㎍/100㎖.
5. The mean of magnesium level in blood was 36.60±7.53㎍/㎖ and the range was 26.7-57.5㎍/㎖.
6. Statistcally, the fraqueacy distribution of mercury, cadmium and copper levels in blood fitted the normal distribution (p>0.05), but the frequency distribution of lead and magassium levels did not fit the normal distrbution(p<0.05)
7. The corralation coafficiant for heavy metals levels showed no interelation at all bet Wccn Mercury and lead (r= -0. 29), mercury and cadmium (r=0.02), mercury and copper (r=0.07), mercury and magnesium (r=0.02), lead and cadmium (r=0.03), lead and copper (r = - 0.06), lead and magnesium (r = 0.05), cadmium and copper (r-0.14) cadniiurn and magnesium (r= -0.03), or copper and magnesium levels (r=0.13).
8. Copper and magnesium levels in the blood were within normal levels. Mercury, lead and cadmium levels did not come close to toxic levels, but there were considerable levels detected in the blood.
