本研究的目的是：(1)测量南非偏远农村社区个体牙齿各部分（牙釉质、牙本质和牙髓周围牙本质）和血液中的铅浓度；(2)调查这些牙齿组织和血液中的铅浓度之间的关系；(3)根据其他研究中报道的牙齿铅浓度来估计血铅。采集48例儿童的乳牙和血液，采用石墨炉原子吸收法进行分析。铅的中位浓度（以mg/kg表示）如下：血液中，0.025；搪瓷,0.25;牙本质,2.04;牙髓周围牙本质，6.71。牙齿铅浓度与来自偏远农村地区的其他研究相似，但由于缺乏先前的数据，无法对血铅进行比较。其他研究中的血铅可以根据本文报道的比率来计算。(C) 2000 Elsevier Science Ltd.版权所有。
The purpose of this study was: (1) to measure the lead concentrations in various parts of the teeth (enamel, dentine and circumpulpal dentine) and in blood from individuals of a remote rural South African community; (2) to investigate any correlation between the lead concentrations in these various dental tissues and in blood; and (3) to estimate blood lead from the tooth lead concentrations reported in other studies. Primary teeth and blood were collected from 48 children and analysed by graphite-furnace atomic absorptiometry. The following median concentrations (expressed in mg/kg) of lead were found: blood, 0.025; enamel, 0.25; dentine, 2.04; circumpulpal dentine, 6.71. The tooth lead concentrations were similar to those from other studies from remote rural areas but comparisons of blood lead were not possible in the absence of previous data. Blood lead in other studies could be calculated from the ratios here reported. (C) 2000 Elsevier Science Ltd. All rights reserved.
