尿砷浓度通常用于确定暴露量，但尿砷水平的最适当表达引起了许多关注。在这项研究中，我们研究了各种调整表达尿砷数据的影响。所有年龄小于72个月且接受过如厕训练的儿童均被邀请参加本研究。收集尿液、土壤和灰尘样本，并进行砷测量。在连续2个早晨提供第一次排尿尿样的儿童中，形态化尿砷的几何平均值为8.6 μ g/l（几何标准差= 1.7，n = 289）。裸露区尿砷形态与土壤砷含量呈显著正相关（p
Urinary arsenic concentration has been used generally for the determination of exposure, but much concern has been raised over the most appropriate expression for urinary arsenic levels. In this study, we examined the influence of various adjustments of expressing urinary arsenic data. All children who were less than 72 mo of age and who were potty trained were invited to participate in the present study. Urine, soil, and dust samples Were collected, and arsenic measurements were made. The geometric mean of speciated urinary arsenic among children who provided first-voided urine samples on 2 consecutive mornings was 8.6 mu g/l (geometric standard deviation = 1.7, n = 289). Speciated urinary arsenic was related significantly to soil arsenic in bare areas (p
