“…Rare-earth elements (REE) in geologic materials were analyzed by Lagarde and Larcher (284) who utilized 241 Am to excite the K lines of the REE, achieving analytical sensitivity in the Mg/g range on pressed-powder pellets. Margolin et al (285) summarized the use of a MECA-10-44 (XR-500) EDXRF for the determination of 10 major and 25-30 rare-earth and other elements in rocks and ores.…”

“…[1] PEDXRF is a very sensitive, fast, easy, highly recommended, nondestructive, reliable, and useful technique to determine the chemical compositions of various types of samples. [2][3][4][5][6][7][8][9][10] Recently, the XRF techniques are one of the most popular methods for food and plant samples analysis. Carvalho and coworkers analyzed heavy metals in wild edible mushrooms under different pollution conditions by XRF spectrometry.…”

In this study, the elemental concentrations of some spice plants gathered from Mut-Mersin in Turkey were analyzed by polarized energy dispersive x-ray fluorescence (PEDXRF) spectrometry. The analyzed spices are peppermint (Mentha piperita), thyme (Thymus vulgaris), and sumac (Rhus glabra). These samples are very often used in the preparation of Turkish foods. The spice samples are indispensable in foods for Turkish people. The results of the analysis show that each sample has different compositions, and some of these elements have a great benefit in human health. The spice samples results reveal that the PEDXRF method is more reasonably sensitive in the determination of the elemental composition of the plants.
