“…The International Federation of Clinical Chemistry (IFCC) had recommended that each laboratory should produce its own reference values. In recent years, a growing number of evidence suggests that reference values of those elements for children would be affected by gender and age . Based on the above studies, established gender‐ and age‐specific reference intervals for relatively healthy pediatric population in local region may help obtaining more accurate estimates of trace elements status.…”

“…Essential metals are coactivators of several important enzymes, including antioxidant enzymes, and proteins which are necessary for health maintenance [ 6 , 7 ]. Therefore, their interactions with lead may affect various fundamental biological processes, including intra- and intercellular signaling, cell adhesion, protein folding and maturation, apoptosis, ionic transportation, enzyme regulation, and release of neurotransmitters [ 3 ].…”

“…Conversely, supplementation with zinc and iron has been shown to reduce intestinal absorption of lead [ 2 ]. Consequently, it is postulated that there are possible feedback loops between blood lead and essential metals [ 7 ].…”

The present study was designed to explore the possible influence of subacute exposure to lead on the levels of selected essential metals, selected proteins related to them, and oxidative stress parameters in occupationally exposed workers. The study population included 36 males occupationally exposed to lead for 36 to 44 days. Their blood lead level at the beginning of the study was 10.7 ± 7.67 μg/dl and increased to the level of 49.1 ± 14.1 μg/dl at the end of the study. The levels of calcium, magnesium, and zinc increased significantly after lead exposure compared to baseline by 3%, 3%, and 8%, respectively, while the level of copper decreased significantly by 7%. The malondialdehyde (MDA) level and the activities of catalase (CAT) and superoxide dismutase (SOD) did not change due to lead exposure. However, the level of lipid hydroperoxides (LPH) in serum increased significantly by 46%, while the level of erythrocyte lipofuscin (LPS) decreased by 13%. The serum levels of essential metals are modified by a short-term exposure to lead in occupationally exposed workers. A short-term exposure to lead induces oxidative stress associated with elevated levels of LPH but not MDA.

“…Nutritional essential elements such as calcium (Ca) and selenium (Se) are coactivators of several important enzymes and proteins which are necessary for health maintenance (Zhao et al, 2013;Wu at al., 2011). Selenium is a naturally occurring micronutrient that is essential for several known major metabolic pathways, including thyroid hormone metabolism and antioxidant defense systems.…”

The aim of this study was to determinate the actual contamination of selected area of Slovakia, in view of its environmental character referred both to the suitability or unsuitability of the use of milk from this area, to other food processing. This article deals with analysis of the content of selected compounds in soil, feed and milk, at the cow and sheep farms. Village in Eastern Slovakia, Tulčík, was the area of investigation. This area is characterized as an area with mild disturbance of environment. 11 compounds have been analyzed (calcium, selenium, cadmium, arsenic, polychlorinated biphenyls -congeners 138, 153, 180, and pesticides -p,p´ DDE, Endosulfan I., Beta-HCH, aflatoxin M 1 ). Samples of soil were collected once a year (spring season), samples of feeds and milk were collected two-times a year (spring and autumn season). Analysis of samples was performed in Eurofins Bel/Novamann (Nové Zámky, Slovak Republic). Analyses were performed by routine methods, according to the valid methodologies. Levels of compounds were obtained and then results have been compared with the most acceptable limits in according to applicable legislation. At both farms, 73.08% (38 samples) of analyzed compounds were below the limit of quantification (LOQ) and 26.92% (14 samples) of compounds were quantifiable. The most significant differences between monitored farms were recorded in soil (27 720 mg·kg -1 Ca), feed (27 620 mg·kg -1 Ca) and milk (960 mg·kg -1 Ca). The high content of calcium in soil and feed did not affect the content of calcium in milk. The results showed that the content of toxic elements, polychorinated biphenyls, pesticides and aflatoxin M 1 in analyzed area of Eastern Slovakia was very low and under the limit of quantification. It can be concluded, that the use of milk from this area for direct use or for dairy products is appropriate and poses no health risk to the consumers.Keywords: essential elements, feed, milk, monitoring, soil, xenobiotics
