In the Valdichiana area (Tuscany, Italy) an ancient native landrace of elephant garlic (Allium ampeloprasum L.), locally known as “Aglione della Valdichiana”, has long been cultivated. The aim of this study was to check whether there are differences in the mineral and nutraceutical profiles of the Aglione della Valdichiana cultivated conventionally and organically. Based on the analysis by ICP-MS of a wide array of major, minor, essential, and non-essential trace elements as well as rare earth elements, and the evaluation of the content of polyphenols, flavonoids, antioxidants, soluble proteins, soluble sugars, and starch, as well as the weight and water content, it was concluded that differences in the mineral and nutraceutical profiles of organically and conventionally grown bulbs were very limited. Only a statistically (p < 0.05) higher concentration of Cd (+2620%), Co (+113%), Mn (+55%), Rb (+180%), and Sb (+180%), as well as glucose (+37%) in conventionally cultivated bulbs emerged. Cadmium was the only element slightly higher than in the “reference plant,” but with a negligible risk (three orders of magnitude lower) for human health based on consumption. It is concluded that we failed to find evidence of healthier food or a higher nutraceutical quality for organically cultivated elephant garlic.

Effective Procedures

There are several international regulations regarding trace elements. The use of ICP-MS for their determination is usually a difficult task, especially when Hg is one of the target elements.

Introduction: This study focuses on the distribution of rare earth elements in rocky shore ecosystem along east coast of Peninsular Malaysia coastal waters using the soft tissue of Saccostrea cucullata, Thais clavigera and Nerita chameleon as bioindicator, and deliberating on interspecies variability. The results were examined in relation to human health as well. Methods: Samples were treated using Teflon Bomb technique and concentrations of 14 naturally occurring REEs were measured using ICP-MS technique, along with selected trace metals for added data. Results:The results were certified using standard reference material BCR 668 with quality control practices. Constant REEs abundance patterns were found in all samples, with enrichment of LREEs over HREEs, which suggests that REEs are transported as a coherent group through aquatic ecosystems. There are variations in the REEs abundance for every site, however, they reveal connections in their REEs distribution patterns, which suggest that they are of parallel origins. As no data on the permissible limits of REEs in biota reported, assessment with permissible limits are quantified by comparing with Hg, Pb and Cd data as REEs concentrations seems to be lower compared with these metal values. Conclusions: Results showed that the values are considerably below the safety limit, with the exception of Ce and Nd in the soft tissue of S. cucullata.

Detecting Method

Food nutrition and food safety have been paid more and more attention, so it is important to find new detecting method. ICP-MS is a good method to detect many elements simultaneously with high accuracy, but detecting more than ten elements simultaneously has little been reported, especially in cereal. Contents of forty elements in corn kernel from Beijing were detected by ICP-MS, we conclude that; 19 elements (Li, I, Co, Ni, Mo, Cs, B, Mn, Fe, Cu, Zn, Rb, Sr, Ti, Cd, Sn, Tl, Pb and Cr) in corn can be precisely and accurately determined simultaneously. As, Se, Bi, Th, U, Sb, Al and rare earth elements could not be precisely detected at this condition, probably due to too low concentrations; Corn from Beijing contains many wholesome trace elements, such as Mo, B, Mn, Fe, Cu, Zn, Rb and Sr; but the toxic elements little, so it is safe and not polluted.

&lt;p&gt;&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;Because the abundances of rare earth elements are strongly intercorrelated, lacking data can be estimated from adjacent element concentrations. Because Ce can be oxidized to Ce(IV) and Eu can be reduced to Eu(II), deviations from the calculated values have been defined as positive or negative anomalies. The anomalies permit conclusions of mineral weathering, transportation and adsorption.&lt;/p&gt;&lt;p&gt;Anomalies detected in soils did not cause respective anomalies in apple leaves, blossom leaves nor fruits, which prevents conclusions of geographical origin. In the apple plants, Ce showed negative anomalies throughout, particularly in the blossom leaves. To the contrary, Eu showed positive anomalies throughout, particularly in the green leaves, which suggests uptake similar to Ca.&lt;/p&gt;&lt;p&gt;In green leaves (apples) growing in the temperate climatic zone, concentrations of rare earth elements increase with age, like for other elements of low physiological interaction also, whereas nutritional and essential trace elements remain constant or decrease.&lt;/p&gt;&lt;p&gt;&amp;#160;&lt;/p&gt;

Siliciclastic Rocks

Fine-grained siliciclastic rocks from the Triassic-Jurassic transition (Rhaetian–Hettangian) in the former Mid-Polish Trough were the subject of the geochemical study at the Polish Geological Institute – National Research Institute in Warsaw. Ninety-four samples of claystones and mudstones from six archived drill cores were analysed by ICP-MS and XRF for rare earth elements (REE) and other trace elements. The results indicate that the sources of most of the claystones and mudstones were sedimentary rocks of the upper continental crust of old cratonic areas, where the protolith had a moderately felsic character. Weathering and recycling processes modified the original chemical composition to some extent. However, during Rhaetian and early Hettangian, some geochemical data in the south-eastern segment of the MPT suggest significant input from a mafic volcanic protolith. Moreover, a clear enrichment in rare-earth elements was observed in few samples, caused by admixtures of accessory minerals (being a main carrier of REE). Nevertheless, based on currently obtained data, the Rhaetian–Hettangian concentrations of REE (and other trace elements) in the MPT are low and they are of scientific indicative significance, not of raw material importance.

Degree Of Differentiation

In the Tanshan area, which is at the Liupanshui Basin, abundant oil shale resources are associated with coals. We analyzed the cores, geochemistry of rare earth elements (REE) and trace element of oil shale with ICP-MS technology to define the palaeo-sedimentary environment, material source and geological significance of oil shale in this area. The results of the summed compositions of REE, and the total REE contents (SREE), in the Yan'an Formation oil shale are slightly higher than the global average of the composition of the upper continental crustal (UCC) and are lower than that of North American shales. The REE distribution pattern is characterized by right-inclined enrichment of light rare earth elements (LREE) and relative loss of heavy rare earth elements (HREE), which reflects the characteristics of crustal source deposition. There is a moderate degree of differentiation among LREE, while the differences among HREE are not obvious. The dEu values show a weak negative anomaly and the dCe values show no anomaly, which are generally consistent with the distribution of REE in the upper crust. The characteristics of REE and trace elements indicate that the oil shale formed in an oxygen-poor reducing environment and that the paleoclimatic conditions were relatively warm and humid. The degree of differentiation of REE indicates that the sedimentation rate in the study area was low, which reflected the characteristics of relatively deep sedimentary water bodies and distant source areas. The results also proved that the source rock mainly consisted of calcareous mudstone, and a small amount of granite was also mixed in.
