“…Determination of nutrient and toxic elements in food samples can be carried out using inductively coupled plasma-optical emission spectrometry (ICP-OES) [8][9][10][11] inductively coupled plasma mass spectrometry (ICP-MS) [12][13][14], flame atomic absorption spectrometry (FAAS) [15][16][17], and graphite furnace atomic absorption spectrometry (GFAAS) [18][19][20][21]. Among the spectrometric techniques used for elementary determination, ICP techniques are outstanding due to their wide linear response, low limits of detection (LODs), multielementary capability, fast analysis, good precision, and accuracy [22].…”

Food security is a priority issue for sustainable global development. In rapid industrialization areas with high fallout of airborne particles, metal uptake by plants could strongly impact crop quality. In this study, concentrations of some heavy metals (Cu, Zn, and Pb) in flour samples supplied in Çorum, defined as one of the “New Industry Focus”, were investigated using inductively coupled plasma-optical emission spectrometry (ICP-OES) to determine the heavy metal contamination. The results showed that the concentration of Pb in all samples examined exceeded the maximum permissible limit. To monitor the increase in Pb concentration and its relationship with air pollution, a two-year laboratory experiment was conducted. It was found that the increase in Pb concentration of about 47% and 77% for two flour samples was consistent with the increase in annual average PM10 concentrations (55% and 82%) obtained from two stations.

“…It is clear that the conventional approach for wet digestion is the use of inorganic acid mixtures. It is worth mentioning that the use of formic acid has also been proposed as a way to completely extract macro-and microelements from feedstuff samples using ICP-OES [22].…”

The present study represents the determination of Ti and Cr in dry animal feeds using wet acid digestion and inductively coupled plasma–atomic emission spectrometry (ICP-AES), in order to use these metals as digestibility markers. A radiofrequency power of 1350 W and a nebulizer argon flow of 0.8 L/min was selected. The limits of detection were between 11.4 and 16.1 μg/g for titanium and between 10.7 and 38.2 μg/g for chromium. The recovery values for the aqueous solutions were 89.5–103.9% (titanium) and 85.3–104.2% (chromium), with relative standard deviations (RSD%) under 2.1% and standard errors under 2.32%, demonstrating that the method offered good accuracy and repeatability. Six different samples of commercially available feedstuffs (two cat foods, two dog foods, and two poultry foods) were analyzed and the levels of investigated metals were found to be in the ranges of 0.10 g/kg and <LOD for chromium and titanium, respectively (dog foods); 0.10–0.18 g/kg, 0.70 g/kg for chromium and titanium, respectively (cat foods); and 0.07 g/kg, 0.82–1.35 g/kg for chromium and titanium, respectively (poultry foods).
