“…These results agreed with those of the previous studies, that is, dietary Se supplementation could increase the total egg Se levels, and the total egg Se levels increased with the improvement of the dietary Se supplementation (75,76). Heavy-metal accumulation in eggs had a positive correlation with the intake of feed contaminated with heavy metals (77), similar to that in fishes and other animals (78). Moreover, a previous study has found that Cr could aggregate more easily than other heavy metals in eggs.…”

Se-rich agro-foods are effective Se supplements for Se-deficient people, but the associated metals have potential risks to human health. Factors affecting the accumulation of Se and its associated metals in Se-rich agro-foods were obscure, and the prediction models for the accumulation of Se and its associated metals have not been established. In this study, 661 samples of Se-rich rice, garlic, black fungus, and eggs, four typical Se-rich agro-foods in China, and soil, matrix, feed, irrigation, and feeding water were collected and analyzed. The major associated metal for Se-rich rice and garlic was Cd, and that for Se-rich black fungus and egg was Cr. Se and its associated metal contents in Se-rich agro-foods were positively correlated with Se and metal contents in soil, matrix, feed, and matrix organic contents. The Se and Cd contents in Se-rich rice grain and garlic were positively and negatively correlated with soil pH, respectively. Eight models for predicting the content of Se and its main associated metals in Se-rich rice, garlic, black fungus, and eggs were established by multiple linear regression. The accuracy of the constructed models was further validated with blind samples. In summary, this study revealed the main associated metals, factors, and prediction models for Se and metal accumulation in four kinds of Se-rich agro-foods, thus helpful in producing high-quality and healthy Se-rich.

“…In general, it seems that the eggs of GLP are characterized by higher content of many essential elements (macro-and microelements), while the concentrations of toxic elements (including heavy metals/metalloids) did not differ from the values given in previous reports [38][39][40]. This is of particular importance in the context of consumer health and safety.…”

“…It should also be remembered that the amount of absorbed metal depends on its form, pH in the digestive tract, the speed of its passage through the digestive system, and the presence of other substances that may modify its absorption. However, the interpretation of the results is complicated due to the complex relationships between chemical elements (synergistic, antagonistic, and agonistic), which makes it difficult to interpret the results objectively, even with the appropriate statistical analysis performed [40,45,46].…”

The goal of this research was to determine the concentration of macro-, micro-, trace, and ultratrace elements in egg albumen and yolk of Green-Legged Partridge (GLP) hens (Polish native breed) maintained in a free-range system. The hens received two feed mixtures (FM), which differed in mineral content (Gr-1 and Gr-2). Analyses of 57 chemical elements were performed using inductively coupled plasma spectroscopy by ICP-OES and ICP-MS techniques. FM from Gr-2 were characterized by a significantly (p < 0.05 or 0.01) higher concentration of macro- and microelements (Al, Ba, Ca, K, P, S, Si) than that from Gr-1. Among the trace and ultratrace elements there were significantly higher levels of Co, Cr, Li, Nb, Ni, Pb, Ru, Sn, and Zr, and significantly lower levels of Cs, Pd, and Te in Gr-2 compared with Gr-1. Egg albumen from hens from the Gr-2 group contained a significantly higher Ba concentration. In the case of trace and ultratrace elements, significantly greater Au, Co, Cr, Mo, Nb, Ru, and Se, and less As were recorded in the albumen from Gr-2. No significant differences were observed in the concentrations of macro- and microelements in the egg yolk. Among the examined trace and ultratrace elements, substantial differences were observed in the level of Co, Cr, Ni, Se, Sn, and Y (more in Gr-2), and Au, Hf, Hg, Nb, Nd, and Rb (less in Gr-2). Only in the case of Co and Cr concentrations in the feed (Gr-2) was a significant increase found in the albumen and yolk. Gr-2 also showed a significantly greater concentration of Ba, Nb, and Ru in the albumen, and Ni and Sn in the yolk.

“…Як відомо, важкі метали здатні накопичуватися на всіх рівнях екологічної піраміди, що значно посилює проблему, а особливо гостро постає проблема їх накопичення у кормах для сільськогосподарських тварин (Zhang et al, 2012;Eskandari & Pakfetrat, 2014;Hejna et al, 2019;Kabeer et al, 2021). Виходячи з вищевказаного, контроль якості та безпеки кормів завжди був актуальним і залишається одним із напрямків роботи ветеринарної медицини України.…”

Assessment of the toxicity of pollutants is an integral part of the quality and safety control of the animal feed. Today, when determining the toxicity of a particular substance, alternative methods are increasingly being used, which involve using cell cultures, protozoa, and photobacteria in a toxicological experiment. The bioluminescence effect of bacteria makes it possible to use them as a substitute for laboratory animals or as an additional test to determine the effect of toxicants, which significantly reduces the cost of work due to the simplicity and speed of research, high sensitivity, and reproducibility. This work aimed to conduct a toxicological assessment of feeds with different levels of heavy metals using the luminescent microorganisms Photobacterium phosphoreum. Under the study of heavy metals, corn grits, which did not possess toxic properties, were used as a “matrix.” Heavy metals were used in the form of State standard samples: Arsenic, Cadmium, Lead, Mercury, Copper, and Zinc. Before adding heavy metals to the feed, the “matrix” was previously examined for their content (background). Toxicants were added to the “matrix” in different concentrations, taking into account the “background” indicators (5 series each), which were prepared by diluting in distilled water, depending on the maximum residue limits (MRL). As a result of the work, the possibility of using luminescent microorganisms Photobacterium phosphoreum (strain IMV B-7071; Sq3) was established for rapid toxicological evaluation of feeds with different levels of heavy metals based on the decrease in the intensity of the glow. However, if for Cd, Hg, Zn, Cu under the conditions of the study of feed with the content of heavy metals at the MRL (0.4; 0.1; 25.0 and 120.0 mg/kg, respectively), the feed was characterized as “non-toxic,” then for Pb and As according to the MRL (5.0 and 0.5 mg/kg, respectively), the feed was characterized as “toxic,” which indicates the need for further studies on the toxicological characteristics of heavy metals in the body of laboratory and productive animals, possibly with a further revision (downward) of the MRL of the relevant pollutants in feed in Ukraine.
