“…Micronutrients may become harmful when their ingestion rates are too high. In contrast, trace elements such as Cd and Pb are well known as toxic if their intake through ingestion or inhalation is excessive (Al-Gahri and Almussali, 2008). The levels of some elements can vary in a large scale.…”

Cereal-based foods have great importance in the compensation of micro- and trace element deficiency, because 50% of the foods produced worldwide are made up of cereal grains. The aim of the research was to determine the concentration of macro-elements and trace elements in different cereals cultivated in Latvia. Various cereals were used in the research: rye (n = 45), barley (n = 54), spring wheat (n = 27), winter wheat (n = 53), triticale (n = 45) and oats (n = 42). Thirteen macro- and trace elements (Cd, Pb, Ni, Cr, Al, Cu, K, Na, Mn, Fe, Zn, Mg, Ca) were determined in cereal grain samples (n = 266). Macro-elements and trace elements varied significantly (p < 0.01 or p < 0.001). The highest concentrations of macro- and trace elements were found in oats and the lowest in rye. The obtained data will expand the opportunity for food and nutrition scientists to evaluate content of the examined elements in grain products, and dietary consumption (bioavailability) of the examined macro-elements and trace elements.

“…The deficiencies, excesses or imbalances in the supply of inorganic elements from dietary sources can have an important deleterious influence on human health [12]. Since 1973, As, Cu, Cd, Fe, Hg, Pb, and Zn have been considered by the joint FAO/WHO Codex Alimentarius Commission to be potentially toxic for human diet with As (as arsenite) being carcinogenic [13].…”

Abstract:Wheat flour is an important source of nutrient and as such is widely consumed in most part of the world, as bread and other pastries. Due to its high consumption, the presence of heavy metal at high concentration would be a significant health risk. Based on the soil in which the wheat was grown and the milling technology employed in making the flour, the heavy metal content of wheat flour varies. In analyzing heavy metal content of flour on the Ghanaian market, (one made in Ghana and another made in Turkey) an atomic absorption spectrophotometric analysis of milestone acid digested flour was used with the appropriate standards. With a 9% -100.4% recovery rate, Fe, Zn, Mn, Cd, Pb were detected at varying concentrations in both flour brands, while Co, Ni, Cu, Cr, As, Hg were below detection limits. The levels of the nutritionally important elements such as Fe and Zn would be beneficial to human health, while those of the toxic element present are not likely to pose any health risk to consumers of this flour.

Abstract. Manganese (Mn) is known to be essential for maintaining the proper function and regulation of many biochemical. To investigate the toxicity of Mn on bird brains, 50-day-old cocks were fed either a commercial diet or a Mn-supplemented diet. the following were determined: Mn concentration, Ca2+ concentration, the expression of Calmodulin (CaM) and Calcineurin (CaN) gene. Exposure to Mn significantly lowered expression of CaM and CaN gene. However, Mn was accumulated in brain and the Ca2+ concentration was increased. These findings suggested that Mn exposure resulted in the damage of cock cerebral tissue by altering calcium homeostasis, which are possible underlying neurotoxicity mechanisms.
