Quantitative correlation among the four metals cadmium, copper, manganese, and zinc was examined in nearly 1500 urine samples collected from adult female inhabitants in 8 nonpolluted regions in various parts of Japan. In addition to a significant correlation between urinary cadmium and zinc as previously reported, copper levels significantly correlated with those of cadmium and zinc. In contrast, manganese did not show any significant correlation with cadmium, copper, or zinc. These findings are in agreement with the fact that cadmium, copper, and zinc are known to combine with metallothionein in vivo, whereas this is not the case with manganese.
在从日本各地8个无污染地区的成年女性居民收集的近1500份尿液样本中，检测了镉、铜、锰和锌这四种金属之间的定量相关性。除了先前报道的尿镉和锌之间存在显著相关性外，铜水平与镉和锌的水平也显著相关。相比之下，锰与镉、铜或锌均未显示出任何显著相关性。这些发现与镉、铜和锌在体内已知会与金属硫蛋白结合，而锰并非如此这一事实相符。
