    A method is described for the determination of microgram quantities of lead in small volumes of urine. Recoveries from urine samples of added lead show that the mean results of triplicate analyses will, 19 times out of 20, lie within ±12·5 μg. per litre of the true concentration. The determination of lead in a single specimen of urine may be carried out in three hours.
