对5名铅作业男工在离开作业环境后不同时间段采集全血和非刺激性混合唾液样本。所有工人的初始血铅浓度都是升高的，然后在清除后缓慢下降。唾液中的铅浓度比血液中的浓度下降得更突然，唾液的半衰期估计为5-7天。2名工人短暂复工后唾液铅浓度明显升高。唾液铅与近期铅暴露密切相关。
Samples of total blood and unstimulated mixed saliva were obtained from 5 male workers occupationally exposed to Pb at various time intervals after removal from their work environment. Initial blood Pb concentrations were elevated in all workers and then slowly decreased upon removal. Pb concentrations in saliva fell more abruptly than those in blood, the saliva half-lives being estimated at 5-7 days. Temporary return to work in 2 workers resulted in relatively marked increases of salivary Pb concentrations. Salivary Pb is closely related to recent Pb exposure.
