Abstract: Total chromium and Cr(VI) contents of cigarets, ash, and smoke formed while burning cigarets were determined The determinations of chromium species were carried out according to procedures developed earlier. Cr(VI) was determined in a combined system, which involves a flow injection (FI) sorption pre-concentration system, hydraulic high-pressure nebulization (HHPN) sample introduction technique, and flame atomic absorption spectrometric (FAAS) detection. The total chromium of samples in Cr(VI) form was determined in this same combined system after ashing cigarets at 800°C [after total conversion of Cr(III) of the sample to Cr(VI)]. It was found that while burning cigarets 0.8-1.2% of the original chromium content of the cigarets comes to smoke in the toxic Cr(VI) form.
