Nearly 1500 spot urine samples were collected in the winter of 1987-1988 from women of seven farming prefectures located throughout Japan. Samples were analyzed for copper by flameless atomic absorption spectrometry. The copper content of the urine samples (Cu-U) distributed log-normally with a geometric mean (geometric standard deviation) of 36.9 (1.47) micrograms/l after adjustment for the specific gravity of urine of 1.016. The 95% confidence range was 17.1-79.7 micrograms/l. Neither alcohol consumption nor smoking habit affected the Cu-U. A literature survey showed that the observed level appears to be somewhat higher than previously reported values.
1987年至1988年冬季，从日本各地七个农业县的女性中收集了近1500份随机尿样。采用无火焰原子吸收光谱法对样品中的铜进行分析。尿样铜含量（Cu-U）经尿比重1.016校正后呈对数正态分布，几何均值（几何标准差）为36.9（1.47）微克/升。95%置信区间为17.1 - 79.7微克/升。饮酒和吸烟习惯均不影响Cu-U。文献调查表明，观察到的水平似乎略高于先前报道的值。
