The mean lead content of deciduous teeth from children living in the city of Birmingham (U.K.) has been shown to be 11.8 ppm dry weight, irrespective of the sex of the donor. Lead content varies according to type of tooth, and there is a gradient from incisors, with the highest level, to second molars, with the lowest. A relationship was shown between age of donor and lead content of canines and (when lognormalized data were considered) first molars. We were not able to demonstrate a correlation between tooth lead levels and residence near a potential industrial lead source, and we conclude that pollution from a general source is responsible for the body burdens we found.
居住在英国伯明翰市儿童的乳牙平均铅含量经测定为干重11.8 ppm，与供体性别无关。铅含量因牙齿类型而异，从含量最高的门牙到含量最低的第二磨牙呈梯度变化。供体年龄与犬齿以及（在考虑对数正态化数据时）第一磨牙的铅含量之间存在关联。我们未能证明牙齿铅含量与潜在工业铅源附近的居住情况之间存在相关性，因此我们得出结论，一般来源的污染是导致我们所发现的人体铅负荷的原因。
