本研究对韩国人全血中的总汞和甲基汞进行了分析，以探讨总汞（T-Hg）和甲基汞（Me-Hg）之间的相关性。 4000份全血样本根据百分位T-Hg浓度分为四组：I组（p25-p50）、II组（p50-p75）、III组（p75-p95）和IV组（p95-p100）。每组随机抽取100份样品，测定Me-Hg浓度。使用直接汞分析仪-80分析全血中的T-Hg浓度，得到的检测限(LOD)为0.2μmgL(-1)。采用顶空气相色谱-质谱联用技术对Me-Hg浓度进行乙醇衍生化分析，得到甲基汞的LOD为0.5μgL(-1)。 T-Hg和Me-Hg的几何平均值分别为6.35μgL(-1)和4.44μgL(-1)，其中71.91%的T-Hg以Me-Hg形式呈现。
In this study, total mercury and methyl mercury in whole blood of Korean was analyzed so as to investigate the correlation between total mercury (T-Hg) and methyl mercury (Me-Hg). 4000 whole blood samples were divided in four groups, according to T-Hg concentration in percentile: group I (p25-p50), group II (p50-p75), group III (p75-p95) and group IV (p95-p100). 100 samples were randomly selected from the each group, and Me-Hg concentration was measured. T-Hg concentration in whole blood was analyzed using a Direct Mercury Analyzer-80 and obtained limit of detection (LOD) was 0.2 mu mgL(-1). Me-Hg concentration was analyzed with ethylate derivatization using headspace-gas chromatography-mass spectrometry, and obtained LOD of methyl mercury was 0.5 mu gL(-1). The geometric means of T-Hg and Me-Hg were 6.35 mu gL(-1) and 4.44 mu gL(-1), respectively, and 71.91% of T-Hg was presented as Me-Hg.
