“…After mineralization at 450 • C, the residue was etched with a mixture of concentrated nitric acid (HNO 3 ,) and perchloric acid (HClO 4 , 70%) (Wieczorek et al, 2005). The metal levels were determined using a flame atomic absorption spectrophotometer PYE UNICAM 939/959 model after extraction into the organic phase with 4-methylpentan-2-one (Skibniewska et al, 2008). The components were analyzed at the Central Analytical Laboratory, University of Warmia and Mazury in Olsztyn.…”

“…Studies by Grzybowski et al (2004Grzybowski et al ( , 2005 and Skibniewska et al (2004) addressed the effect of pesticide tombs located in the region of Warmia and Mazury on flora and fauna as well as on the bioaccumulation of organochlorine pesticides and heavy metals in aquatic ecosystems (Skibniewska et al, 2008). The results of these studies demonstrated that despite the presence of low levels of contaminants including persistent organic pollutants (POP) and heavy metals in most of the environmental samples from the region of Warmia and Mazury, there is still a risk that areas adjacent to the pesticide tombs may contain increased concentrations of contaminants.…”

The concentrations of the heavy metals lead (Pb) and cadmium (Cd) were determined in berries (blackberry, raspberry, bilberry, wild strawberry), and hazelnuts picked from plants in the wild as well as in fruit (blackberry, raspberry, blueberry) and hazelnuts picked from orchard-farmed plants in northeastern Poland. The levels of seven congeners of polychlorinated biphenyls (PCB(7)), gamma isomer of hexachlorocyclohexane (gamma-HCH), and sum of dichlorodiphenyl trichloroethane and its metabolites (SigmaDDT) were also measured in plants and nuts. In addition, the concentrations of Pb, Cd, PCB(7,) gamma-HCH, and SigmaDDT were determined in the surface samples of soil from the sites of fruit picking. The highest acceptable concentrations based upon Polish standards for Pb and Cd were not exceeded in forest fruit. In wild berries, Pb occurred at a level below the detection limit, whereas the concentration of Cd ranged from 6 to 49 microg/kg fresh weight. The levels were Cd 72 microg/kg fresh weight and Pb 290 microg/kg fresh weight in raspberries from orchard plants and exceeded the maximal acceptable limit of 50 microg/kg for Cd and 200 microg/kg for Pb. The level of Pb at 210 microg/kg fresh weight in hazelnuts from orchard plants also exceeded maximal acceptable limits. Individual samples of fruit, regardless of their origin, were found to contain trace amounts of organic pollutants such as 1,1-dichloro-2,2-bis(4-chlorophenyl)ethylene (p,p'-DDE) and PCB congeners 101 and 118. All soil samples contained from 3.2 to 14.9 mg/kg dry weight concentrations of Pb and most soil samples also contained Cd. Further, individual soil samples were found to contain high levels of SigmaDDT (145 microg/kg), including p,p'-DDT at a concentration of 67 microg/kg. The concentrations of persistent organic pollutants (POP) in wild and orchard-farm-grown fruit in northeastern Poland were generally below threshold permissible limits, and no correlation was found between levels of contaminants in soils and POP concentrations in fruit.

“…However, there is a risk associated with the consumption of fish, as pollutants from the environment may enter the body (Jia et al 2017). Water and soil contamination lead to the transfer of heavy metals (e.g., mercury, arsenic, lead) and chemical compounds into living organisms, where they accumulate in fish tissues and organs (Skibniewska et al 2008).…”

Magnesium is the second most abundant intracellular cation and one of the most abundant element in the body. Although the total serum magnesium content does not represent more than 1% of total body magnesium, serum magnesium determinations have been routinely used in clinical practice to assess body magnesium status. Hypomagnesemia (low magnesium status), which is associated with many chronic diseases, is diagnosed using the serum magnesium reference range. In the recently published paper [Rosanoff et al. 2022], the authors have discussed the cut off value of the lower level of magnesium normal status in blood serum. However, this recommendation concerns only the total magnesium concentration. It is known for many years that ionized magnesium concentration in blood serum can give us additional and valuable information about body magnesium status [Saaris et al. 2000]. Ionized magnesium concentration in blood serum was found significantly lower, compared to control, in acute myocardial infarction and diabetes mellitus type I (D I). Total magnesium level was within physiological range in both cases. Recently, the serum Mg isotopic signature was investigated in a cohort of patients suffering from D I and compared to that in age-and gender-matched reference population (assumed healthy individuals) [Grigoryan et al. 2019]. Patient were re-evaluated after one year. Several references materials were measured for validation purposes. The serum Mg isotopic composition of D I patients Year 1 and Year 2 was lighter than the serum Mg isotopic composition of the reference population. To investigate the possible source of isotopic composition changes during Mg transfer through the cellular membrane, diffusion of Mg and Ca through the artificial, ion selective membrane, has been investigated.

“…Recently, various dumps have become sources of serious environmental contamination. Very often they were built without due care which allowed leaks to occur from the deposits (Skibniewska et al, 2008). Every kind of waste, including pesticides, contains some quantity of heavy metals that can escape into the soil and ground water.…”

Fifteen samples of fish fillets were collected from different Egyptian markets to detect the residues of some heavy metals in them. The average weights of fish fillets samples were 250g. The samples were separately packed in polyethylene bag and sent to the laboratory for preparation and analysis. All equipment surfaces and utensils which used in this study were thoroughly cleaned with detergent, rinsed with water, dried and then rinsed with 2-propanol solution. The samples were stored at -2C prior to analysis. The mean levels of lead and cadmium in fish fillets collected from the Egyptian markets were 1.51  0.34 and 0.60 0.0.25 mg/kg; respectively. The concentration of lead in fish muscle were less than the permissible heavy metal limit in fish meat (2.0 mg kg) as stated by the World Health Organization, also these results were in line with the corresponding EU regulations. However the level of cadmium concentration was over than the heavy metal limits in fish meat (0.5 mg/kg) for the World Health Organization.
