Abstract I describe a micro-scale method for determining lead in whole blood by utilizing a graphite furnace. Sample pretreatment consists of fivefold dilution with a dilute surfactant. The method is directly calibrated with lead standards prepared in dilute HNO3. To eliminate a small, nonspecific absorption signal from the blood matrix, simultaneous background correction is used. Interlaboratory comparison with a flame atomic absorption technique that requires extraction yielded high correlation (r = 0.98). Within-run precision (coefficient of variation) ranged from 2 to 4%. Lead in blood can be accurately measured in as little as 20 µl of blood, hence the method is suitable for routine laboratory use and for pediatric screening.

Absorption Technique

A flameless atomic absorption technique, employing a tantalum strip atomizer, has been developed to determine barium and antimony in gunshot residue. Cotton swabs, wetted with 5% HNO3, are used to collect residue. Barium and antimony are released from the swabs by acid leaching or plasma ashing. Both techniques give good recoveries; the ashing technique is preferred for blood-stained swabs. The sensitivity for barium is 0.1 ng/10 µl and antimony 0.2 ng/10 µl. At nanogram levels the standard relative deviation for barium is 8.3% and for antimony 8.5%.

Abstract I describe a sensitive, specific, automated method for determination of mercury in urine by the "flameless atomic absorption" technique. One can analyze 20 samples per hour, with less than 0.5-ml samples of urine. The detection limit is 0.01 mumol/liter (2mug/liter) and the mean coefficient of variation 12%. The procedure is being used to monitor mercury excretion by workers exposed to mercury.
