“…During the two-or three-step simulation of digestion, a sample is fragmented and incubated in typical organism temperature, which is around 37°C, with the addition of corresponding enzymes and in the appropriate environment (strongly acidic for gastric and neutral for intestinal digestion). 21 Usually, the first step, imitating digestion in the oral cavity is neglected, and the number of enzymes used is reduced to the two most important ones (pepsin for gastric and pancreatin for intestinal digestion). 20 In this way, a rapid, convenient and cheap method is obtained, which gives the opportunity of measuring various parameters on each step of digestion.…”

BACKGROUND The transformation of nanoparticles (NPs) internalized in plant tissues is the human digestive system that can provide a better understanding of the impact of NPs on the human system. The presented methodology was developed to study the bioaccessibility of cerium oxide (CeO2) and copper oxide (CuO) NPs from radish after the in vitro simulation of gastrointestinal digestion using single‐particle inductively coupled plasma mass spectrometry (SP‐ICP‐MS). RESULTS Radish plants were cultivated hydroponically in a growth medium containing: (i) CeO2 NPs and (ii) CuO NPs. Both cerium (Ce) and copper (Cu) were found in all organs of the radish plants after analysis by standalone ICP‐MS. This confirms the bioaccumulation of CeO2 and CuO NPs and the translocation of their Ce and Cu to the aerial parts of the plant. Less Ce (4.095 μg g−1) has been detected in leaves than in roots (1.156 mg g−1) while Cu content in leaves was 5.245 μg g−1 and in roots was 10.41 μg g−1. Analysis of the digestive extracts obtained after the in vitro simulation of gastro (pepsin) and gastrointestinal (pancreatin) digestion showed that Ce has easy access to human system at least by 73%. CONCLUSION The size of CeO2 NPs in digestive extracts showed no significant changes. However, the results obtained for CuO NPs digestion were variable and suggested that CuO NPs dissolved during the digestion process. The CuO NPs were observed in roots after the gastrointestinal digestion concluding that CuO NPs recovered after the initial dissolution. © 2020 Society of Chemical Industry

“…Of course, both anion and cation exchange columns are sometimes used in a complementary fashion [130]. Based on the requirement of pH, phosphate [131], carbonate [132], nitrate [133], acetate [134] or miscellaneous [122,135] are commonly used as buffers. The anion-exchange mode with phosphate buffer elution is classically used for the separation of As(III), As(V), MMA and DMA.…”

In order to obtain a well understanding of the toxicity and ecological effects of trace elements in the environment, it is necessary to determine not only the total amount, but also their existing species. Speciation analysis has become increasingly important in making risk assessments of toxic elements since the toxicity and bioavailability strongly depend on their chemical forms. Effective separation of different species in combination with highly sensitive detectors to quantify these particular species is indispensable to meet this requirement. In this paper, we present the recent progresses on the speciation analysis of trace arsenic, mercury, selenium and antimony in environmental and biological samples with an emphasis on the separation and detection techniques, especially the recent applications of high performance liquid chromatography (HPLC) hyphenated to atomic spectrometry or mass spectrometry.

“…5 Currently, there is a great interest for the determination of a large number of essential macroelements, microelements and toxic elements in vegetables and fruits (tomato, asparagus, garlic, parsley, spinach, strawberry, cherry, grape, apples, etc.). [7][8][9][10][11][12][13][14][15][16][17][18][19][20] Various analytical methods such as inductively coupled plasma optical emission spectrometry (ICP-OES), 7,[21][22][23] inductively coupled plasma mass spectrometry (ICP-MS), 24,25 flame atomic absorption spectrometry (FAAS), 13,18,26 electrothermal/graphite furnace atomic absorption spectrometry (ETAAS/GFAAS), 13,15,[27][28][29] thermal decomposition atomic absorption spectrometry (TDAAS), [30][31][32] cold vapor atomic fluorescence spectrometry (CV-AFS), 33 X-ray fluorescence spectrometry (XRF), 25 proton induced X-ray emission spectrometry (PIXE) 34 and photochemical vapor generation capacitively coupled plasma microtorch optical emission spectrometry (UV-PVG-µCCP-OES) 19 were used for the determination of elements in vegetables and fruits. Until now, the ICP-OES is standardized method for the determination of selected elements in water, 35 while GFAAS for Pb, Cd, Zn, Cu, Fe, Cr and As in foodstuffs.…”

This study presents the validation of inductively coupled plasma optical emission spectrometry (ICP-OES) for the determination of macroelements and microelements, graphite furnace atomic absorption spectrometry (GFAAS) and thermal decomposition atomic absorption spectrometry (TDAAS) for essential traces and toxic elements in vegetables and fruits. The limits of detection were in the range 0.02-5 mg kg-1 for ICP-OES, 0.004-0.025 mg kg-1 for GFAAS and 0.004 mg kg-1 Hg for TDAAS. Accuracy of the methods was checked by analysis of certified reference materials that provided recovery in the range 87-108%. The precision assessed from the analysis of real samples of dried goji berry was in the range of 1.5-10.0%. The spectrometric methods fulfilled the requirements of Association of Official Agricultural Chemists (AOAC) and European Commission so that ICP-OES, GFAAS and TDAAS were considered appropriate for determination of elements in vegetables and fruits.
