The region of Warmia and Mazury is characterized by the special diversity and richness of its natural environment, including large forest complexes, where wild mushrooms are commonly collected and consumed. This study aimed to examine the differences in mineral content (calcium, magnesium, sodium, potassium, iron, zinc, copper, manganese) of three species of mushrooms collected in north-eastern Poland. The research material consisted of dried samples of king bolete (Boletus edulis), bay bolete (Boletus badius), and chanterelle (Cantharellus cibarius) collected in the region of Warmia and Mazury. The content of the above-mentioned elements in mushroom fruit bodies was determined using the flame atomic absorption spectrometry (acetylene-air flame) and the emission technique (acetylene-air flame) for sodium and potassium. For the majority of micro- and macroelements, the studies confirmed the presence of significant differences in their content, depending on the species of fungi. The studied mushrooms cover a significant percentage of daily demand for many of the minerals. This concerns mainly copper, zinc, and potassium, although none of the species was a good source of calcium and sodium. Among the analyzed mushrooms, chanterelle is the best source of most minerals.

Abstract Background: Neurodegeneration is complex and multifaceted leading to many chronic diseases like Parkinson’s disorder. Electrolytes imbalance have significant role in the pathophysiology of neurological disorders, which might be serve as a bio-indicator of the neurological problems. In present study, the disturbances of electrolytes (calcium, magnesium, sodium and potassium) and its correlation with biochemical parameters in patients with Parkinson’s at different stages with related to referent were studied. Methods: The biological samples were collected from patients recently diagnosed for mild Parkinson disease (MPD) (n=95) as well as chronic PD (CPD) patients, diagnosed for last 5 to 10 years (n=125).The Precision of digestion method was verified by applying matrixes matched certified reference materials of biological samples. The recovery of electrolytes was obtained in the range of 98.4–99.1 % of certified reference materials. The electrolytes concentrations were measured by acid digested biological samples preliminary analysis through flame atomic absorption spectrometry. Results: The experimental data indicated the content of Calcium and Magnesium were found to be higher in scalp hair samples of both patients while Sodium and Potassium showed inverse relation (p<0.05 for both groups). Electrolytes levels in blood serum and plasma was found to be lower in both types of patient groups than healthy groups (p<0.01). Conclusions: These results suggest a disturbance in the elemental homeostasis during the diseases of PD at different stages. In spite of, additional work is proposed to study the actual correlation among micro elemental level and the grade of diseases in neurological sick person.

Samples of barley, oats, lupins, peas, rape, linseed and safflower were analysed at five growth stages for nitrogen, phosphorus, potassium, sulphur, calcium, magnesium, sodium, chlorine, silicon, copper, zinc and manganese. The results are summarized and compared with those for wheat published in a previous paper. The data are discussed in relation to nutrient removal and the effect on soil fertility.

Seven elements, namely, arsenic, lead, cadmium, copper, zinc, iron and manganese were determined in 31 samples of Serbian plum brandies by applying atomic spectrometry techniques. Flame atomic absorption spectrometry was used for quantification of copper, iron, zinc, manganese, lead and cadmium; and hydride generation atomic spectrometry absorption for arsenic quantification. Measured concentrations of heavy metals and arsenic was assessed according to the Serbian regulations, official regulations of some other countries and in respect of microelements content in other similar distilled alcoholic beverages. Amounts of microelements in maximal recommended daily and weekly intake of plum brandy were determined. The influence of production (home made and industrial), type of wooden barrel (oak and mulberry), and duration of ageing process on the content of Zn, Cu, Fe and Mn in plum brandies, as well as coefficient of correlation between Cu content and pH value were also studied.
