“…At present, essential and toxic metals in food and beverages are qualitatively and quantitatively studied by using mainly atomic absorption spectrometry (AAS) (dos Santos et al 2009;Jalbani et al 2010;Kazi et al 2010), inductively coupled plasma mass spectrometry (ICP-MS) (Roychowdhury et al 2003;Nardi et al 2009;Kaňa 2010) and inductively coupled plasma optical emission spectrometry (Lara et al 2005;Oleszczuk et al 2007;Santos et al 2008). Other techniques include X-ray fluorescence spectrometry (Jastrzebska et al 2003), electromigration techniques (Sadecka & Polonsky 1999;Szlyk et al 2004), and some electrochemical techniques (Karadjova et al 2000;Abbasi et al 2010;Alghamdi 2010).…”

We determined the mineral nutrients and toxic elements (Ca, Cu, Fe, Mg, Zn, Cd, Cr, Mn, Ni, and Pb) in five types of coffee by atomic absorption spectrometry and inductively coupled plasma mass spectrometry. The decomposition of the samples took place in a microwave digestion system with HNO 3 and H 2 O 2 reagents. Partial validation of the method was performed by using the certified reference material (NCS ZC 73014). Univariate and multivariate statistical methods were used to compare both the coffee samples and the techniques used. No significant differences were found between two used methods. Significant differences occurred between the coffee samples but only the application of multivariate statistics helps to distinguish among samples from different locations.

“…Several techniques are used for element analysis, including flame atomic absorption spectrometry (Rosa et al., 2015), differential pulse anodic stripping voltammetric techniques (Alghamdi, 2010), stripping potentiometry (Clark, Kontoudakis, Barril, Schmidtke, & Scollary, 2016), capillary zone electrophoresis (Suárez‐Luque, Mato, Huidobro, & Simal‐Lozano, 2006), inductively coupled plasma emission spectroscopy (Chung, Kim, Lee, & Kim, 2015), and microwave plasma atomic emission spectroscopy (Nelson et al., 2015). In particular, the kinetic energy discrimination (KED) in collision/reaction cell ICP‐MS is an effective technique to reduce polyatomic ion interferences (Yamada, 2015); this technique was widely used in this study to alleviate polyatomic interferences.…”

Bupleuri Radix is a famous traditional Chinese medicine (TCM) and an important raw material in TCM patent prescriptions. It is widely used in several countries, including China, Japan, South Korea, and America. However, the impact of heavy metal transfer rules on TCMs remains unknown. In this study, a total of 45 paired original medicines (OMs), decoction pieces (DPs), and vinegar‐processed (VPs) samples were simultaneously determined via inductively coupled plasma‐mass spectrometry after a microwave digestion. The concentrations of the elements were shown at three levels: (a) Al and Fe at the mg/g level; (b) Pb, Cu, Ba, Mn, Cr, and Ni at the mg/kg level; (c) Co, As, Cd, and Hg at μg/kg level. It is worth noting that the Cu levels were found to exceed the maximum concentration set by Chinese legislation (20.0 mg/kg). In addition, Mn, Ni, and Cu levels were higher in samples from the Gansu province than those from other provinces. The accumulation of the heavy metals decreased in the order of OMs > DPs > VPs; this was especially true for the Al and Fe levels. Furthermore, the results indicate that decocting the samples may reduce the intake of heavy metals. The element transfer ratios for decoctions were under 50% compared to herbal medicines and decreased in the order of Co > As > Mn > Hg > other metals. Our study strongly suggests that long‐term and regular monitoring for heavy metals in the plant is necessary.
