Abstract

日本人における,非職業的水銀蒸気曝露者の血中総水銀量及び,尿中総水銀量の参照値をもとめた.試料は,テフロン密栓容器で分解後,還元気化-金アマルガム捕集-原子吸光光度法により,総水銀量を測定した.34〜65歳の一般女性56人における,血中総水銀量の平均値は,18.2±9.9ng/ml(範囲3.9〜56.8ng/ml)であった.22〜39歳の一般男性130人における,尿中総水銀量の平均値は,2.33±1.50μg/l(範囲0.27〜10.26μg/l)であった.比重補正した尿中総水銀量の平均値は,2.19±1.15μg/l(範囲0.68〜7.68μg/l)であり,クレアチニン(Cr.)補正した尿中総水銀量の平均値は,1.51±0.68μg/g Cr.(範囲0.39〜4.21μg/g Cr.)であった.これらの値は,ヨーロッパ諸国の報告やわが国のこれまでの報告とそれほど大きな相違がみられなかった.尿中総水銀の表示法として,比重補正値とクレアチニン補正値を比較すると,後者の方が最小値と最大値の輻はせまくなった.

We investigated the background levels of total mercury in blood and urine samples from Japanese subjects without occupational exposure to mercury vapor. Blood and urine specimens were decomposed in sealed Teflon containers, and total mercury concentration was measured by reductive vaporization-gold amalgam capture-atomic absorption spectrophotometry. The mean total mercury concentration in the blood of 56 women aged 34-65 was 18.2±9.9ng/ml (range 3.9-56.8ng/ml). The mean total mercury concentration in the urine of 130 men aged 22-39 was 2.33±1.50μg/l (range 0.27-10.26μg/l). The mean total mercury concentration in urine adjusted by specific gravity was 2.19±1.15μg/l (range 0.68-7.68μg/l), and that adjusted by creatinine was 1.51±0.68μg/g creatinine (range 0.39-4.21μg/g creatinine). These concentrations did not differ greatly from those reported from Europe and Japan. In expressing the total mercury concentration in urine, the creatinine-adjusted range between the minimum and maximum values was smaller than the range adjusted by specific gravity.
