“…The mean REE concentrations detected in the EVOOs are shown in Figure 2a, while the mean REE contents (≥LOQ) of each olive oil sample during the 2019-2021 period from different geographical origins are reported in Table 2. Despite the limited data on REE contents available in the literature, the concentration range that we detected ranged between 0.09 and 4.22 ng g −1 , in accordance with the results of different authors, which were well summarized in a recent study [69], who reported ranges varying between 0.002 and 7 ng g −1 in olive oils from costal region. Our values also agree with those described by other authors in other areas [2,[70][71][72].…”

Extra virgin olive oil is a food product from the Mediterranean area that is particularly and continuously experiencing to increasing instances of fraudulent geographical labeling. Therefore, origin protection must be improved, mainly based on its intrinsic chemical composition. This study aimed to perform a preliminary chemical characterization of Abruzzo extra virgin olive oils (EVOOs) using rare earth elements (REEs). REEs were evaluated in EVOO samples of different varieties produced in different geographical origins within the Abruzzo region (Italy) in three harvest years using ICP-MS chemometric techniques. Principal component, discriminant, and hierarchical cluster analyses were conducted to verify the influence of the variety, origin, and vintage of the REE composition. The results of a three-year study showed a uniform REE pattern and a strong correlation in most EVOOs, in particular for Y, La, Ce, and Nd. However, europium and erbium were also found in some oil samples. Compared with cultivar and origin, only the harvest year slightly influenced the REE composition, highlighting the interactions of the olive system with the climate and soil chemistry that could affect the multielement composition of EVOOs.

“…Very scarce are the data about trace elements and, in particular, REE distributions in Olea europaea L. However, as in other food products, the behaviour seems typical with a low amount in olive pulp [ 3 , 39 , 40 ]. Our results of REE concentrations, from olive pulp analysis for each cultivar, are reported as average values with standard deviations, in nanomoles kg −1 in Table 2 .…”

The identification of a product, with its geographical origin, is a guaranty of the value of the foodstuff and protection from potential fraud. Extra virgin olive oil is produced or marketed as a single variety or a blend of two or more cultivars, often of different geographic origins. Therefore, to study a possible link between the soil and olive oil, we accounted crucial to analyse the behaviour of olive of different cultivars. We studied Rare Earth Elements (REE) amounts and their relationship to trace their distribution from soil to the olive pulp (Olea europea L.). The results obtained pointed out that the different cultivars of Olea did not drive significant differences in reciprocal ratios of REE in the uptake from the soil up to olive (except for Eu). However soil-plant Rare Earth relationships depend exclusively on the soil REE composition. This method can be the starting point to enforcing the laws, in fact, it is important to develop analytical methods to measure the authenticity of the samples, and to verify the geographical origin even when olive oil is blended.

“…Chem. Acta 2020, 93 (2) Al and P. [37] Even though the influence of soil characteristics on plant uptake of REY in a natural environment is still largely unknown, the study of Pošćić et al [37] suggests that the specific local soil condition, such as pH and phosphorus availability, could explain most of the REY variability in plants, including also leaves. Interestingly, the REY levels in studied citrus leaves were substantially lower or comparable to the lowest values reported by Miao et al [38] for leaves of Eucalyptus globulus Labill, Dicranopteris dichotoma, and Pinus massoniana, although the concentrations of REY in soils reported by these authors are comparable to REY levels in soils from Croatia.…”

[37,39,40] Thereby, it should be noted that the concentration levels of major and trace elements recorded in the ornamental plant substrate (pH 5.0-6.5) available on the Croatian market [41] are comparable or even lower than those in Croatian soils. [40] Furthermore, the general order of REEs concentrations in different compartments of the citrus system was reported to decrease in the following order, soil > leaf > peel > pulp > seed > juice.…”

The present study aims to discuss the data on levels and distribution of rare earth elements, including Y, (REYs) in leaves of three different citrus species (lemon, orange, and tangerine) and provide additional information about the major, minor and trace elements in two biological certified reference materials (CRMs), Apple leave (NIST SRM 1515) and Rye grass (ERM CD281). In all samples, element concentrations were determined by High Resolution Inductively Coupled Plasma Mass Spectrometry. The obtained data display substantial variability in the distribution of REY elements, not only between different citrus species but also between different genera of plants indicating their different uptake and accumulation abilities. Measured concentrations of REYs in citrus leaves were substantially lower compared to the literature values, although the fractionation indices were comparable. The data for CRMs provide additional information for the 14 elements in NIST SRM 1515 and the 30 elements in ERM CD281, including rare earth elements.
