Sažetak
The aim of this paper was to determine impact of soil chemical properties and different wheat genotypes in Croatia on micronutrient and toxic elements content in wheat integral flour. Research was conducted and soil sampes were collected from two different production areas in Republic of Croatia: Ovčara and Dalj. Besides soil samples, grain samples of four different Croatian wheat genotypes were also collected and analyzed. In total, 40 samples of soil and 40 samples of wheat grain were analysed to total (aqua regia) and plant available (EDTA extraction) heavy metal content of Fe, Mn, Zn, Cu, Pb, Cd. Determined soil pHKCl ranged from 5, 63 to 6, 25 at Ovčara and from 6, 95 to 7, 37 at Dalj site. The highest total concentration of heavy metals in soil were determined for Fe, followed by Mn, Zn, Cu, Pb and the lowest total concentration was recorded for Cd. The highest EDTA concentrations in soil were determined for Mn, than followed Fe, Cu, Pb, and the lowest EDTA concentration was recorded for Cd. The highest concentration in integral wheat flour was found for Fe, than lower for Mn, Zn, Cu, Pb and the lowest concentration was found for Cd. If consumers in Croatia use daily 203 g of bread made by integral flour, thay would intake 2, 31 to 8, 44 µg Cd daily, depending on soil and wheat genotype. The analysed soils and winter wheat genotypes have significant impact on potential daily intake of toxic and essential heavy metals by integral flour or bread.
