Trace Metal Contents of Some Medicinal, Aromatic Plantsand Soil Samples in the Mediterranean Region, Turkey

In this study, concentrations ofnine trace metals, i.e., manganese, zinc, copper, nickel, lead,. ... ..cadmium, iron, chromium and .copalt··have:·been determined in thirteen different spices. . .... .and plants having folk medecinal uses. Arnicrowave -digestion procedure has been used todissolve trace metals in samples HN03:H202 4:2). All metals in the samples were analyzedusing flame and graphite furnace atomic absorption spectrometry. The metal concentrationsin the samples were found to be 26.4-324.0, 78.2-2 11.0, 14.5-214.0, 1.9-330.2, 0.1-0.4,0.3-0.7, 117.6-619.7, 0.1-0.9 and ·0.1-0.3 (mu)g/g for manganese, zinc copper, nickel lead,cadmium, iron, chromium and cobalt, respectively. The present study provides baseline dataon essential trace metal levels in spices and medicinalplants.
