Abstract

The total chromium, Cr(III) and Cr(VI) contents of cigarettes of different types and of ash and smoke formed during the burning of cigarettes were determined. Determinations of Cr(VI) were performed in a combined system, which involves a flow injection (FI) sorption preconcentration procedure, hydraulic high-pressure nebulization (HHPN) sample introduction and flame atomic absorption spectrometric (FAAS) detection. The total chromium of the samples in Cr(VI) form was determined using sorption preconcentration in FI-HHPN/FAAS system after ashing cigarettes at 800°C (total conversion of Cr(III) in the sample to Cr(VI)). The Cr(IH) contents of the samples were determined using C18 column chromatographic preconcentration with KH-phthalate and FAAS detection. During the burning of cigarettes, 0,8-1,2 % proportion of the original chromium content of the cigarettes gets into the smoke in the form of toxic Cr(VI). It was studied how the different chromium forms depend on the temperature of the ashing and how large the conversion of the Cr(III) to Cr(VI) at different temperatures is.
