Speciation of chromium in bread and breakfast cereals

Chromium(VI) content in breakfast cereals ranged between 20.4 ± 4 μg kg−1 and 470.4 ± 68 μg kg−1. Therefore, it can be concluded that bread and breakfast cereals contains Cr(VI) which does not exceed maximum acceptable concentration (MAC) of 0.003 mg kg−1bw−1 day−1 through daily consumption of half a bowl (65 g) of breakfast cereal and four slices of toasted (122 g) or untoasted bread (160 g).
