Cadmium Level in Blood and Urine of a Male Korean Occupationally Non-exposed to Cadmium

In order to determine the blood and urine cadmium levels among male Korean, we collected blood and urine samples from 365 men in Choongcheong province without occupational exposure to cadmium. The blood and urine cadmium levels were analyzed by graphite furnace atomic absorption spectrophotometer. The summarized results were as follows. ① The average cadmium levels of subjects were 0.96±0.40㎍/ℓ(GM: 0.88±1.47㎍/ℓ, Range: 0.31∼2.69㎍/ℓ) in blood, and 0.86±0.63㎍/ℓ(GM: 0.69±1.97㎍/ℓ, Range: 0.07∼4.26㎍/ℓ) in urine. ② Blood cadmium levels were significantly correlated to urine cadmium levels(r=0.419). ③ Blood and urine cadmium levels were significantly increased with increase of age and the number of cigarette smoked per day(p<0.001). ④ Blood and urine cadmium levels for drinking group were significantly higher than that for non-drinking group(p<0.05, p<0.01, respectively). ⑤ Multiple regression analysis showed that the number of cigarette smoked per day contributed to blood and urine cadmium level (p<0.001), and age contributed to urine cadmium level (p<0.05, p<0.001, respectively).
