본 연구에서는 ICP-MS의 혈장 중 극미량의 납 분석법을 검증하기 위하여 Class 1,000 이내의 환경조건을 확보한 후 특이성, 일내 및 일간 정확도, 정밀도, 검정곡선 등을 확인하였다. 청정실의 부유 분진량을 측정한 결과, 0.3 μm 크기는 0.3~62개, 0.5 μm 크기는 0.0~28.3 개로 총 부유분진량이 최대 90.3개로 요구 환경에 부합하였다. 우태아 혈청 공시료로 조제한 시료의 MDL (Method detection limit)은 1.77 ng/L이고, LOQ (Limit of quantification)값은 5.55 ng/L 이었다. 검정곡선은y=1.09×10−3x+4.88×10−2이었고, 상관계수 r=0.9999이었다. 분석법 확립을 위한 특이성, 일내 및 일간 정확성, 정밀성, 그리고 검정곡선을 확인한 결과 50 ng/L 이상에서 분석법 확인 기준에 적합하였다. 이를 토대로 분석한 일반인의 혈장 중 납 농도 평균은 55.4 ng/L 이었으며, 현직 근로자는 440 ng/ L 이었고, 퇴직 근로자는 132 ng/L 이었다.
The analytical method of lead in plasma by ICP-MS was validated after securing environment within class 1,000 classification. We tested specificity and accuracy of within-run and between-run. According to measurement of the amount of suspended particulates in a clean room, 0.3~62 particles were detected in 0.3 μm size while 0.0~28.3 particles were observed in 0.5 μm size. Total suspended particulates met required environment with up to 90.3 particles. The MDL (Method detection limit) of the sample which has been fabricated using fetal bovine serum (FBS) blank was 1.77 ng/L, and LOQ (Limit of quantification) was 5.55 ng/L. The slope, intercept and correlation coefficient of the calibration curve were y=1.09×10−3x+4.88×10−2 and r=0.9999, which showed good correlation. The specificity, withinrun and between-run accuracy satisfied the standard at more than 50 ng/L. The average lead concentration in plasma of the general people, current workers and retired workers was 55.4 ng/L, 440 ng/L, and 132 ng/L.
