Sweat was collected from the arms of 24 normal healthy subjects while they sat in a hot chamber. Blood, urine and saliva samples were also collected. These were analyzed for lead by atomic absorption spectrophotometry. Sweat lead levels recorded in this study are lower than those previously reported. Subjects with mean blood lead levels of 8.62 micrograms dl-1 (range 6-13.6) had mean sweat levels of 5.2 micrograms l-1 (range 1.5-13.0), approximately 25% of their urinary levels. Although salivary lead levels with a mean of 4.8 micrograms l-1 (range 2.5-10) are comparable to sweat levels, their relationship to blood lead levels is poor (r = -0.186 compared with r values of 0.7208 and 0.234 for sweat and urinary levels, respectively).
24名正常健康受试者坐在热室内时，从其手臂采集汗液。同时还采集了血液、尿液和唾液样本。通过原子吸收分光光度法对这些样本进行铅含量分析。本研究记录的汗液铅水平低于先前报告的水平。平均血铅水平为8.62微克/分升（范围为6 - 13.6）的受试者，其平均汗液铅水平为5.2微克/升（范围为1.5 - 13.0），约为其尿液铅水平的25%。虽然唾液铅水平平均为4.8微克/升（范围为2.5 - 10），与汗液铅水平相当，但其与血铅水平的关系较差（相关系数r = -0.186，而汗液和尿液水平的r值分别为0.7208和0.234）。
