Abstract

The purpose of this study was to estimate total selenium concentration in Helianthus Annuus L. collected from different regions in Turkey by graphite furnace atomic absorption spectrometry (GFAAS), prior to microwave digestion. The accuracy of the techniques was evaluated by using certified reference material NIM-GBW07404 (GSS-4) and WEPAL-IPE-168 for soil and sunflower plant . The precision of the techniques, expressed as relative standard deviation, was observed under 8 % for GFAAS measurements. The concentrations of total selenium in plant , seed and soil collected from different regions were found in the range of 0.10-1.76 mg/kg for Helianthus Annuus L. in Turkey during 2 years.
