Three children were born in the Broken Hill Australia lead mining community with delayed visual maturation of the optic nerve (blindness) within a period of 19 months. Because of the association with the lead pollution, the delayed visual maturation was attributed to lead exposure of the fetus during pregnancy. Lead isotopic analyses of the shed deciduous teeth from the three children demonstrate that they were not exposed to increased levels of lead from a mining or any other source during pregnancy and the etiology of the delayed visual maturation must be sought elsewhere.
在澳大利亚布罗肯希尔铅矿开采社区出生的三名儿童，在19个月内出现了视神经视觉成熟延迟（失明）的情况。由于与铅污染有关联，视觉成熟延迟被归因于胎儿在孕期接触了铅。对这三名儿童脱落的乳牙进行的铅同位素分析表明，他们在孕期并未接触到来自采矿或任何其他来源的铅含量增加，视觉成熟延迟的病因必须从其他方面寻找。
