In this study, the lead contents of different kinds of lipsticks were determined by solid sampling high resolution
continuum source electrothermal atomic absorption spectrometry (SS-HR-CS ET AAS) and the
results were compared with those obtained after microwave-assisted acid digestion of the samples.
The experimental parameters for solid sampling such as the maximum amount of sample on the platforms
of solid autosampler, graphite furnace program were optimized. Samples were directly loaded
on the platforms of solid autosampler between 0.25 and 2.0 mg and lead was determined applying
800 C for pyrolysis and 2100 C for atomization. Under optimized conditions, interference-free determination
could be performed using aqueous standards. The LOD and the characteristic mass were 21.3 and
12.6 pg, respectively. The lead in the same lipstick samples was determined after microwave-assisted
acid digestion and compared with those found by solid sampling. Mostly, there was no significant difference
between the lead concentrations found by the two techniques. The lead in 25 lipstick samples with
different properties were 0.11–4.48 ng mg1 which were not significantly different from those (
