Abstract

An accurate analysis method for the determination of lead in whole blood by ICP/MS was developed. Whole blood samples were decomposed in microwave digestion system without any contamination and loss of lead. The 96 samples were analyzed by ICP/MS using mass$^{208}$ isotope of lead. Lead concentrations of human whole blood were ranged of $2.50{\sim}22.8{\mu}g/dL$. The accuracy of this analysis method was verified by analyzing of NIST SRM 955a series(lead in blood).

ICP/MS에 의해 전혈 중의 납을 정확하게 분석하는 방법을 개발하였다. 전혈시료를 납의 오염과 손실 없이 마이크로파 분해장치에서 분해시키고, 96개 혈액시료 중의 $Pb^{208}$을 ICP/MS로 측정하여 분석하였다. 실제 인체 혈액 시료 중의 Pb 함량은 $2.50{\sim}22.8{\mu}g/dL$ 범위였다. NIST SRM 955a series를 분석함으로써 이 분석방법의 정확도를 확인하였다.
