Serial radiographs of lead-poisoned children showed separation of lead lines from the zone of provisional calcification within four weeks at sites of rapid growth. Lead lines do not appear until blood lead attains a concentration of 70 to 80 micrograms/dl. They are not affected by treatment, but disappear spontaneously within four years. While they remain in the diaphysis, they provide a marker for the time of onset of lead toxicity and the subsequent rate of bone growth.
铅中毒儿童的系列X光片显示，在生长迅速的部位，铅线在四周内从临时钙化区分离。直到血铅浓度达到70至80微克/分升时铅线才会出现。它们不受治疗影响，但会在四年内自行消失。当它们留在骨干时，可为铅中毒的发病时间及随后的骨骼生长速度提供一个标记。
