Distribution Of Micro (Fe, Zn, Cu, and Mn) and Risk (Al, As, Cr, Ni, Pb, and Cd) Elements in the Organs of R. Alpinus L.

Abstract Background and aimsRumex alpinus is a native plant in the mountains of Europe, whose distribution is affected by its utilization as a vegetable and medicinal herb. The distribution of micro and risk elements in its organs and the possibility for phytoremediation are not well-known. We aimed to examine the safety of consuming R. alpinus from the Krkonoše Mountains, Czech Republic, and Alps (Austria and Italy).MethodsWe determined the total and plant-available concentration of Fe, Zn, Cu, Mn, Al, As, Cr, Ni, Pb, and Cd in the soil and total concentration in the organs of R. alpinus using inductively coupled plasma-optical emission spectrometry.ResultsThe uptake and distribution of elements by plants were characterized by bioaccumulation and translocation (TF) factors. The intensity of elements accumulation by R. alpinus is considerably different, depending on locality. R. alpinus has considerable tolerance to Zn, Cu, As, Cr, Ni, with easy accumulation strategy. High Al and Cd concentration in belowground biomass (rhizome) indicates a defensive mechanism for them. Although the aboveground biomass (emerging, senescent, mature leaves, petiole) has some degree of accumulation of risk elements, R. alpinus is potentially suitable for phytoremediation of moderately contaminated soils. The results revealed that R. alpinus excludes Al, with high TF for Mn, Zn, Cu, As, Ni, and Pb. Given the accumulation of As and Cr, we recommend caution in its usage.ConclusionDetailed elemental analysis of R. alpinus organs is recommended before its application as medicinal herb or food, especially in contaminated soils.

Precise estimation of metals in samples remains a challenge as a result of analytical biases and errors, which occur at sample collection, preparation, and measurement stages. A poor understanding of the nature and occurrence of these errors further aggravates this challenge. This study aimed at comparing the effectiveness of inductively coupled plasma (ICP) mass spectrometry (MS) and optical emission spectrometry (OES) techniques in quantifying metals from contaminated soils of Roundhill landfill vicinity. Using statistical tools, the study evaluated biases of the 2 methods. High coefficients of variation were realized for V, Cr, and Pb concentrations varied at various sampling sites. Concentrations of elements obtained using the 2 methods had no significant differences using t-test analysis. Definitive agreement for the 2 methods was observed for V, Cr, Co, Ni, Cu, Zn, Sr, and Pb concentrations, whereas the concentrations of Mg, Ca, Ti, Mn, and Fe showed some deviations in their regression lines. Spectral, systematic, memory, and carry over errors could be attributable to these deviations. The errors promote chelation and adsorption of ions in samples to form insoluble compounds that cannot be quantified. Overall, ICP-MS had greater sensitivity than ICP-OES in trace elements analysis compared with major elements.

Energy-dispersive X-ray fluorescence spectrometry (EDXRF) is a rapid and inexpensive method for soil analysis; however, analytical results are influenced by particle size effects and spectral interferences. The objective of this study was to optimise sample preparation and calibrations to improve the accuracy of EDXRF for soil tests. Methods of sample preparation were compared by calculating the recoveries of 13 elements in four International Soil-Analytical Exchange (ISE) standards prepared as loose powder (LP), pressed pellet (PP), and pressed pellet with wax binder (PPB). A matching library (ML) was created and evaluated against the fundamental parameters (FP) calibration using 20 ISE standards. Additionally, EDXRF results of 41 tillage soils were compared with Inductively coupled plasma optical emission spectrometry (ICP-OES) results. The PPB had most recoveries within the acceptable range of 80–120%; conversely, PP yielded the poorest element recoveries. For the calibration, the ML provided better recoveries of Ni, Pb, Cu, Mg, S, P, and Cr; however, for Zn, and Mn, it had the opposite effect. Furthermore, EDXRF results compared with ICP-OES separated by soil texture class for Al, K, Mn, and Fe. In conclusion, the EDXRF is suitable for quantifying both trace elements and macronutrients in contaminated soils and has the potential to provide screening or prediction of soil texture in agriculture.

Although the aboveground biomass (emerging, senescent, mature leaves, petiole) has some degree of accumulation of risk elements, the results showed that Rumex alpinus is an excluder.ConclusionRumex alpinus does not accumulate risk elements in organs that are consumed based on the World Health Organization (2001) and can therefore be consumed without concern.

Fennel, mint (peppermint), and sage herbal teas and apple, lemon, and rosehip fruit teas were selected for the determination of the following risk elements contents: aluminium (Al), arsenic (As), barium (Ba), cadmium (Cd), nickel (Ni), lead (Pb), and antimony (Sb). Moreover, the effect of lemon on these elements contents was also examined. Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) was used for these experiments on selected teas (2 g of tea infused in 100 ml of water). The maximum changes of elements concentrations after the lemon addition were as follows: Al 1077 µg/l in lemon tea; Ba 12560 µg/l in rosehip tea; Cd 183 µg/l in sage tea; Ni 1136 µg/l in fennel tea; and Pb 238 µg/l in lemon tea. Both As and Sb were below the detection limits in pure tea and lemon-infused teas. This study indicated that after the lemon addition, rosehip tea had a hazard index (HI) value of 10827 × 10<sup>–4</sup> for 200 ml/day (2 cups/day), which represents a high risk for human health. If lemon is added to rosehip tea for consumption, 100 ml/day is recommended according to the calculated HI values.

Iron Forms

This article presents studies on iron speciation in the pottery obtained from archaeological sites. The determination of iron forms Fe(II) and Fe(III) has been provided by a very simple test that is available for routine analysis involving the technique of molecular absorption spectrophotometry (UV–Vis) in the acid leachable fraction of pottery. The elemental composition of the acid leachable fraction has been determined by inductively coupled plasma optical emission spectrometry (ICP-OES). Additionally, the total concentration of the selected elements has been determined by X-ray fluorescence spectrometry with energy dispersion (EDXRF). The results of the iron forms’ determinations in archaeological pottery samples have been applied in the archaeometric studies on the potential recognition of the pottery production technology, definitely going beyond the traditional analysis of the pottery colour.
