Abstract

A dry ashing method is described for the determination of lead in whole blood. Within the range of 16-200 μg. lead per 100 ml. blood recoveries were 82 to 100%. The method agreed with a standard wet method and is more convenient. Possible sources of error and the uses of the ashing aid are discussed.
