Samples of blood, sweat and urine were collected from eight control subjects and 19 lead workers in a battery manufacturing factory in the tropics. Sweat samples were collected while workers cycled on a bicycle ergometer at room temperature (27-31C). All samples were analysed by atomic absorption spectrophotometry. Workers with blood lead levels of 13-36g/dl had sweat levels of 72-256g/l and urinary levels of 28-288g/g creatinine, while controls had levels of 9-12.2g/dl, 9-30g/l and 9-19.6g/g creatinine, respectively. Estimations of sweat lead in lead workers can be masked by skin contamination.
