“…Similar to our results, their contents in laboratory‐extracted oils were ~10 times lower than in the industrially processed oils made from roasted seeds. Mitić et al () also analyzed the content of potassium in Serbian pumpkin seed oils and found similar values for roasted oils; however, values for cold pressed oils were much higher than the ones from this research.…”

“…Nickel, manganese, and cobalt were not detected. Furthermore, Mitić et al () reported even higher values of iron (up to 67.4 mg/kg). Roasted pumpkin seed oils analyzed in their work seemingly contained higher amounts of iron, even though the statistical significance was not established.…”

“…The levels of selenium for oils in their research were below the method limit (0.001 mg/kg). On the other hand, Mitić et al () determined concentration of selenium in pumpkin seed oils up to 1.21 mg/kg, which indicates that the amount of that element can vary greatly. Because oils from this study and previous ones have been performed on the pumpkin seed samples originating from different areas, this variation in the content of selenium can be explained by differences of its concentrations in the soil.…”

Macro‐ and microelements in the samples of virgin and cold pressed pumpkin seed oils produced in Croatia through two consecutive crop seasons were determined by inductively coupled plasma–optical emission spectroscopy (ICP‐OES). Croatian oils were also compared to oils from Slovenia and Austria in order to assess differences in the element content. Magnesium, potassium, calcium, sodium, selenium, and iron were the dominant elements in all pumpkin seed oils. Their amounts together with barium, strontium, manganese, copper were up to ninefold higher ( p ≤ 0.05) in virgin compared to cold pressed pumpkin seed oils. These differences occur due to the different processing conditions which include salt addition, heat treatment, and higher degree of equipment ware out during virgin pumpkin seed oil production. As the sodium level increases with the addition of salt, virgin pumpkin seed oil could be considered its hidden source and producers should pay attention to the amount added. Contents of cobalt, copper, selenium, and thallium significantly differed ( p ≤ 0.05) between the two crop seasons. Principal component analysis revealed clear differences between samples with different origin that can be explained by the specifics in the production processes of each country. In comparison with Austrian and Slovenian, Croatian pumpkin seed oils had significantly lower contents of sodium, potassium, calcium, magnesium, and tin while bismuth and selenium were higher.

“…23 In the present study, using a 27.12 MHz ICP, RF power, and nebulizer argon flow rate were varied under the constant values of other plasma conditions. 24,25 Also, both viewing modes (axial/radial) were considered in this study. In order to eliminate the memory effect, the delay time for washing between samples and signal measurement was set to 30 s. Mermet 26 reported that plasma robust conditions can be represented by a Mg II 280.270 nm/Mg I 285.213 nm ratio (Mg II/Mg I) higher than 10.…”

This study aimed to optimize and validate the inductively coupled plasma optical emission spectrometric method (ICP OES) for the simultaneous determination of eleven potentially toxic elements (Al, Cd, Cr, Co, Cu, Ni, Pb, Fe, Sb, Mn, and Zn) in lipstick samples. The method was evaluated by applying the standard addition method. The recoveries for all elements in lipsticks were between 90% and 110%, except for Cd and Pb they were <90% and >110%, respectively. The health risk assessment was determined by calculating the average daily intake (ADD), hazard quotient (HQ), and hazard index (HI). The highest mean value for ADD was for Fe (4.8 × 10-1 mg kg-1 day-1), and the lowest was for Co (9.3 × 10-6 mg kg-1 day-1). There was no significant toxic health risk for any of the elements (HQ < 1), except for Fe (HQ < 3) which indicates a potential health risk. Based on PCA, all potentially toxic elements have been classified in the three groups. The first group includes Fe, the second includes Al, and all other elements belong to the third group. The cluster analysis of the elements provided the identical grouping that was obtained on the basis of PCA. Two separate clusters were obtained when cluster analysis was applied to the analyzed samples. The first cluster contained the only sample that was brown. The second cluster was divided into two sub-clusters. The first sub-cluster included the samples belonging to category I regarding the price, while the second sub-cluster included the samples belonging to category II and III regarding the price.
