Whole teeth obtained from handicapped children and from controls have been analysed for lead by anodic stripping voltammetry. No significant differences were found between the two groups. Teeth originating from the same patient showed systematic variations in lead content that are dependant on anatomical tooth type. The nature of this association is discussed. Analyses of sectioned teeth revealed, for cadmium and copper, unexpectedly large variations. High concentrations of cadmium found in the tips of deciduous incisor teeth indicate a probable contribution from maternal blood.
已采用阳极溶出伏安法对残疾儿童和对照组儿童的完整牙齿进行了铅含量分析。两组之间未发现显著差异。同一患者的牙齿铅含量呈现出因牙齿解剖类型而异的系统性变化。本文讨论了这种关联的性质。对牙齿切片的分析显示，镉和铜的含量存在意想不到的巨大差异。在乳牙切牙尖端发现的高浓度镉表明可能来自母体血液。
