“…Thus, oils originating from almonds or hazelnuts are used for discussion. Compared to the literature data, the Cd content found is lower in other types of edible oil, such as hazelnut oil [21,33,34]. Conversely, the results for Cr are higher than in all reported hazelnut oils [32,33,34].…”

Walnuts (Juglans nigra) are considered to be a functional food. In the present study, twenty one macro-, micro-, and trace elements (Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Se, Sr, and Zn) were selected to be determined in walnuts and walnut oils. The beneficial content of essential elements could be shown by the obtained results, the macro-elements Ca, K, Mg, and Na being present in nuts with 1062 mg/kg, 2771 mg/kg, 1426 mg/kg, and 42.3 mg/kg, respectively. Regarding micro- and trace elements, the following order (decreasing content) was found: Mn > Fe > Zn > B, Mo > Cu > Ni > Co > Al > Sr > Ba > Li > Pb > Se > Cr > As > Cd. Furthermore, the potentially toxic trace elements (As, Cd, Pb) determined were below the maximum allowed values in most of the investigated walnut samples. A comparison of oils and nuts revealed that the former contain lower concentrations of all elements analyzed except for Fe and Zn. This suggested the origin from contamination during oil processing. Fe influences the oil oxidation rate, thus its entry during production should be avoided.

“…The levels of nickel in a comparison study were also not detected in sunflower oil and were lower than the LODs [30]. The presence of four elements, Cr, Cu, Fe, and Mn, was observed in all types of oils, and in the case of Cr, its concentration was higher in the vegetable oils other than olive oils.…”

The water aquifers of the regions of Asopos River in Viotia and Messapia in Evia (Greece) have been contaminated with hexavalent chromium (Cr (VI)) and bivalent nickel (Ni (II)). Given that these areas are the two biggest tuber producing regions of Greece, in our previous work, the cross-contamination of the food chain with these two heavy metals was quantified. In the present study, the potential of sunflower (Helianthus annuus) cultivation in these regions is evaluated. The scope of our study was to investigate the uptake of chromium and nickel by sunflower, in a greenhouse experiment. The study included two cultivation periods of plants in six irrigation lines with different levels of Cr (VI) and Ni (II) ranging from 0 μg/L (control) to 10,000 μg/L. In all plant parts, statistically significant increased levels of Cr (VI) and Ni (II) were found when compared to control ones. Also, a positive correlation, both for Cr and Ni, between levels of heavy metals in irrigation water and plants was observed. Following European Food Safety Authority recommendations, the obtained oil was evaluated as safe for consumption, therefore, sunflower cultivation could be a valid bioremediation solution for the Asopos and Messapia regions.

“…The chemical analysis constitutes an important tool for the quality control in food industry where on-line, fast and simple methods are required [10][11][12]. Several studies have been carried out on the determinations of the metals in various edible oils, in different parts of the world, by using the analysis techniques, such as: flame and graphite furnace atomic absorption spectrometry [13,14], neutron activation analysis [15], electrothermal atomic absorption spectrometry [16,17], inductively coupled plasma-atomic emission spectrometry [18,19] and inductively coupled plasma optical emission spectrometry [20].…”

In recent years, increasing attention has been paid to oils consumed by humans. The human body uses oils in the diet for three purposes: energy source, structural component and powerful biological regulators. Elemental profiling of macro-, essential elements constitutes an important tool for quality control in terms of nutritional values of these products. Regarding this, Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) determinations were performed to assess the quantitative complement of essential mineral and toxic metals content of different edible oil types, from Romania market, summing 33 samples, after microwave digestion. Additionally, the carbon stable isotope ratios (13C) were determined by Isotope Ratio Mass Spectrometry (IRMS) in order to differentiate the specific fingerprint of investigated oils.
