Multi-Elemental Analysis of Crepis Sahendi Boiss Grown in Iraqi Kurdistan Region Using ICP-OES/ICP-MS Techniques

Abstract

ABSTRACT:Crepis sahendi Boiss is perennial plant growing in Iraqi Kurdistan region. Traditionally, it is used for the treatment of abdominal ache. The objective of this study is to evaluate the element contents of root, stem, leaf and flower of C. sahendi, which were determined using microwave assisted digestion followed by ICP-OES/ICP-MS techniques. Sixty-five elements were analyzed from the studied plant parts. Element concentrations of Pt, Pd and Re have not been detected in any parts of the studied plant. Some elements were present only in specific parts, such as; Ta, Ti, U, Ho, Lu, Tm, Yb W, In and Te. The rest of the elements were detected in all parts of C. sahendi in different concentrations. Lead and Arsenic reach the toxic concentrations in flower with 45.9 ppm and 25.6 ppm respectively. Chromium was also showed in a toxic ratio within root, leaf and flower with 8.04 ppm, 7.43 ppm and 3.47 ppm respectively. The determination of metals as toxic ratio was depended on the WHO references. The presence of these toxic heavy metals in such a ratio in the selected parts of C. sahendi make us believe that this traditional plant is not safe to be used by consumers in the sampling area.

Inductively Coupled Plasma-Optical Emission Spectrometric Determination of Some Elements from Anchusa azurea Mill. Collected in Iraqi Kurdistan Region

“…To estimate the metals in plants, numerous techniques have been used after the dissolution step, for instance: colorimetric, polarimetry, voltammetry, capillary electrophoresis, neutron activation analysis, scanning electron microscopy-energy dispersive X-ray analyzer, flame atomic absorption spectrometry and electrothermal atomic absorption spectrometry, inductively coupled plasma-atomic emission spectroscopy which is the same to inductively coupled plasma optical emission spectrometry, inductively coupled plasma mass spectrometry. One of the most powerful technique is inductively coupled plasma, due to their quick multi-elemental analysis capability and high sensitivity (Ibrahim, et al, 2015;Osw & Masum, 2017). The use of ICP-OES is an appropriate choice for their determination of the higher concentration of metals because no further dilution of the sample solution is needed (Rodushkini & Huhtasaari, 1999;Wu et al, 1997).…”
