A pilot study to evaluate the efficacy of using high precision lead isotopes as an indicator of previous lead exposure in children was undertaken on deciduous teeth from 10 children in a lead-mining city. The present study illustrates the applicability of the method and provides data from two subjects who had different exposure to lead during early childhood. Teeth were examined by slicing the crowns into upper and lower sections and/or by selective dissolution with different mineral acids. Different exposures to mine lead and other sources, such as food, water, air (gasoline), are readily detected in any tooth from an individual.
在一个铅矿开采城市，对10名儿童的乳牙进行了一项初步研究，以评估使用高精度铅同位素作为儿童既往铅暴露指标的有效性。本研究说明了该方法的适用性，并提供了两名在幼儿期铅暴露情况不同的受试者的数据。通过将牙冠切成上下两部分和/或用不同的无机酸进行选择性溶解来检查牙齿。在个体的任何一颗牙齿中都能很容易地检测到来自矿山铅和其他来源（如食物、水、空气（汽油））的不同暴露情况。
