ANALYTICAL METHODS Toxicological Profile for Lead

Limits of detection for lead using AAS are on the order of µg/mL (ppm) for flame AAS measurements, while flameless AAS measurements can detect blood lead levels at about 1 ng/mL (Flegal and Smith 1995). A detection limit of 0.05 ng/mL has been achieved for lead in blood samples analyzed by GFAAS (Flegal and Smith 1995). ICP/MS is also a very

Analytical methods for measuring lead in blood

3.1 Atomic absorption spectrometry (AAS) AAS is based on the fact that free atoms absorb light at wavelengths characteristic of the element of interest. The amount of light absorbed can be correlated in a linear fashion to the concentration of the analyte in the sample. To conduct an AAS measurement, the lead-
