No full textThe trace element contents of seven kinds of herbal plants and spice samples retailed in local markets in Kayseri-Turkey were determined by flame atomic absorption spectrometry after digestion with HNO3/H2O2 mixture. The concentration ranges for the studied elements were found as 6.0-15.2, 0-32.2, 80.0-324.8, 8.1-386.3, and 13.1-36.2 mu g/g for copper, nickel, iron, manganese, and zinc, respectively. The levels of cobalt, lead, and chromium ions in all the investigated samples were found to be below the detection limit of flame atomic absorption spectrometry. The results found in the present work were compared with values in the literature
