The concentrations of zinc, copper, iron, nickel, cadmium, lead, manganese, sodium and chloride in the sweat of six males and three females were determined after collections utilizing a total body washdown technique. From our results, sweat appears to be an important excretory pathway for zinc and copper. The mean concentrations of nickel and cadmium in sweat were higher than those reported for urine, that of lead was similar to urine. The loss of manganese in sweat is significant. Levels of zinc and iron were lower in sweat from females, possibly reflecting compensation for menstrual and other losses. Collections were made in six subjects simultaneously utilizing a total body washdown method and collections from one arm in an occlusive arm-bag. The arm-bag collection method gave higher and more variable results and is not recommended as an indicator of loss from the entire skin surface.
采用全身冲洗技术收集六名男性和三名女性的汗液后，测定了其中锌、铜、铁、镍、镉、铅、锰、钠和氯的浓度。根据我们的结果，汗液似乎是锌和铜的重要排泄途径。汗液中镍和镉的平均浓度高于尿液中的报道值，铅的浓度与尿液中的相似。汗液中锰的流失量很大。女性汗液中锌和铁的含量较低，这可能反映了对月经及其他流失的补偿。同时采用全身冲洗法对六名受试者进行收集，并通过封闭的手臂袋收集一只手臂的汗液。手臂袋收集法得到的结果更高且更具变异性，因此不建议将其作为整个皮肤表面流失情况的指标。
