Mercury (Hg) concentrations were determined in human urine and hair samples from Gouxi (GX, n=25) and Laowuchang (LWC, n=18), Tongren, Guizhou, China, to evaluate human exposure from artisanal Hg mining. Geometric means of urinary Hg (U-Hg) were 216 and 560 μg g(-1) Creatinine (μg g(-1) Cr) for artisanal mining workers from GX and LWC, respectively, and clinical symptoms (finger tremor) were observed in three workers. The means of hair Me-Hg concentrations were 4.26 μg g(-1) (1.87-10.6 μg g(-1)) and 4.55 μg g(-1) (2.29-9.55 μg g(-1)) for the population in GX and LWC, respectively. Significant relationship was found between estimated rice Me-Hg intake and hair Me-Hg levels (r=0.73, p<0.001). Co-exposure to Hg vapor and Me-Hg may pose health risks for the study population.
在中国贵州铜仁的高溪（GX，n=25）和老钨厂（LWC，n=18），测定了人体尿液和头发样本中的汞（Hg）浓度，以评估手工 Hg 开采对人体的暴露情况。来自 GX 和 LWC 的手工开采工人的尿汞（U-Hg）几何平均值分别为 216 和 560μg g(-1) Creatinine（μg g(-1) Cr），有 3 名工人出现了临床症状（手指震颤）。GX 和 LWC 人群的头发中 Me-Hg 浓度均值分别为 4.26μg g(-1)（1.87-10.6μg g(-1)）和 4.55μg g(-1)（2.29-9.55μg g(-1)）。估计的大米 Me-Hg 摄入量与头发 Me-Hg 水平之间存在显著关系（r=0.73，p<0.001）。Hg 蒸气和 Me-Hg 的共同暴露可能会对研究人群的健康构成风险。
