The study aimed at assessing the sodium and potassium content in chosen tissues and organs of free-ranging European bisons in Białowieża Primeval Forest depending on the gender and age of animals. In order to determine the content of elements in parenchymal tissues, ribs and hair, the ICP-OES method was used. In the hooves, sodium and potassium were determined with the help of ICP-MS. The sodium content in organs and skin appendages varied from 0.30 in hair to 4.77 mg g-1 in ribs. In the analysis of the age effect, some significant differences were observed between the investigated groups in the sodium content of the hoof wall, namely, a higher mean value was noted in young individuals. The potassium content in the examined samples was within the range of 0.96 in the hoof wall to 3.63 mg g-1 in kidneys. Significant age dependent differences were noted only in the ribs. Sodium and potassium concentrations in the hoof wall were correlated in a highly significant way. Similar dependences also appeared between the content of sodium and potassium in kidneys and liver and kidneys and muscles. On the basis of the results it can be concluded that the status of sodium and potassium supply in the European bison from Białowieża Forest is adequate.
Foliar application of growth regulators or fertilizers containing biostimulators can influence the uptake and accumulation of mineral elements by plants. A pot experiment carried out in two annual series (year of experiment I and II) examined the effect of various concentrations of Tytanit applied once or twice against mineral fertilization (NPK), in comparison with the control object (without fertilization) and the object with mineral fertilization (NPK), on the total content of potassium, calcium, magnesium and sodium in petioles and leaf blades of celery. The experiment involved the application of various concentrations of Tytanit, ranging from 0.001% to 3.6%. The content of selected elements in the plant material was determined after dry mineralization, using the ICP – AES method. The total content of potassium in petioles of celery fertilized with NPK + 3.6% was higher or the same as in the control and in plants fertilized with NPK (I and II series). The results were similar in the case of leaf blades (except for series I). The highest concentration of Tytanit (3.6%) resulted in a reduction of the total calcium content in both of the tested parts of celery and magnesium in petioles, compared with the control. On the other hand, the total content of sodium increased along with the growth of the fertilizer concentration. The highest bioaccumulation of calcium was observed in celery cultivated in the object without fertilization (control). A significantly higher potassium content (mean from both series of research) and over two-fold higher content of calcium were found in celery leaf blades than in petioles, while a higher content of magnesium and sodium appeared in petioles than in leaf blades. The values of (K+Na) : (Ca+Mg) ratios in leaf blades were found to be over two-fold higher than in petioles of celery fertilized with Tytanit.
This paper discusses some aspects of the research conducted in the hydrological years 2000/2001-2002/2003 on arable areas around several small water bodies located on the outskirts of villages in the commune of Kąty Wrocławskie. The aim of the paper was to assess the content of selected chemical elements in the groundwater and small water bodies. The water bodies included in the research appeared a few decades ago as a result of human activity; in Zybiszów and Bliż they are small post-mine water bodies, whereas in Smolec and Rybnica they are ponds filling former clay excavation sites. Their surface ranges widely between 0.05 and 2.2 ha, while the average depth reaches 1.2 to 3.5 m. Since no flows come to these water bodies, they are fed only by ground and rain water. In the research period the water level of the bodies fluctuated between 3 and 40 cm, while the maximum changes in the groundwater level were above 1 m. The examined waters contained elevated levels of elements, the fact which is directly related to the kind of soils in the region. Another factor affecting the content of elements is whether or not soils are used agriculturally. It has been observed that arable areas are distinguished by positive correlation of magnesium, potassium and sodium concentrations in ground and surface waters. Increased content of these elements in Rybnica suggests that the waters receive pollutants from nearby houses. In the groundwater examined the ratio of calcium and magnesium concentrations ranged from 2.7 to 6.9, whereas in the surface water it varied from 1.2 to 5.1. Values below 3 were obtained for both types of water only in Rybnica, which proves the influx of sewage from households.
The study aimed at evaluating the influence of soil contamination with nickel on a background of varied liming on cadmium, molybdenum, and sodium contents in red clover biomass. The four-year pot experiment was carried out using a completely randomized pattern in which the following factors were examined: I – soil contamination with nickel (0, 50, 100, 150 mg Ni kg⁻¹ soil); II – liming (no liming or liming according to 0.5, 1.0, and 1.5 Hhsoil). Red clover (Trifolium pratense L.) as a test plant of which the seeds were sown every year, with its biomass harvested 4 times per each vegetation season. The content of Na, Cd and Mo was determined by the ICP-EAS technique. Study results were statistically processed by applying variance analysis, while LSD(0.05)values were calculated according to the Tukey test. In order to find dependencies between examined features, linear correlation analysis was performed as well. The soil contamination due to nickel up to 100 mg kg⁻¹ soil caused a decrease of Cd content with an increase at the highest contamination level of 150 mg kg⁻¹ soil, while decrease of Na and Mo concentrations at all applied nickel rates. Liming made average Na and Cd contents lower and mean Mo level higher in red clover biomass.
Na podstawie wyników badań wypiekowych uzyskano wskazanie o możliwości absorpcji do struktury produktu, otrzymanego z mąki pszennej, dodanych pierwiastków z równoczesnym zmniejszeniem o 50% udziału soli technologicznej (chlorku sodu). Zastosowanie soli dolomitowych dodatnio wpłynęło na spektrum pierwiastków w eksperymentalnym produkcie, szczególnie wapnia i magnezu. Obniżenie udziału soli (chlorku sodu) w procesie technologicznym spowodowało wyrównanie proporcji między sodem a potasem, do 1:1. W obrazach mikrostruktury eksperymentalnego ciasta pszennego po procesie fermentacji wystąpiło zjawisko wydłużonych, przestrzennych „kieszeni" białek glutenowych, zachowujących gazowe metabolity fermentacji. Spowodowało to poprawę cech funkcjonalnych produktu. Istniejąca możliwość uzyskania produktu uzupełniającego dzienne niedobory pierwiastków z ograniczeniem podaży sodu jest wskazaniem o jego charakterze profilaktycznym, jednak przy akceptacji mniej słonego smaku.
Mineral alluvial and deluvial soils, mineral-organic mucky soils and organic peat-muck soils were developed from the Holocene deposits in northern Poland. The total content of Ca, Mg, K, P, Na, Fe, Mn, Zn and Cu was analysed in the following soils: alluvial soils which were formed from riverine deposits in delta and riverine landscapes, deluvial soils which were developed from slope deposits in a landscape of moraine hills and plains and in a riverine landscape as well as in mucky soils and peat-muck soils located in a landscape of moraine hills and plains and delta landscape. The aim of the paper was to determine total amount of the elements in a soil profile and catena sequence in the mentioned landscapes. Total content of analysed elements in the soils developed from the Holocene deposits varied considerably among the soil types, in a soil profile, among catena sequences and landscapes. The highest content of Fe, Mn, Mg, K, Zn and Cu was reported in alluvial soils whereas Ca reached the highest level in peat-muck soils. In the riverine landscape, the highest accumulation of total Ca, Mg, K, P, Na, Fe, Mn, Zn and Cu was stated for alluvial soils, having the lowest location in the catena. In the landscape of moraine hills and plains, total content of K, Zn and Cu was the highest in deluvial soils and mucky soils located in the lower part of the slope. The total content of Ca and P was the highest in peat-muck soils having the lowest location in the catena. Statistically significant differences in the content of Ca, Mg, K, and Cu were stated between alluvial soils in the riverine and delta landscapes. The differences in the content of analysed elements, excluding Cu, were also statistically significant between alluvial and deluvial soils.

Presenting detailed picture of psychical problems in healthy controls and patients enabled to see indirect important effect of polyetiological determinants of metabolism of minerals in 388 subjects included in the study, whose blood serum and hair were tested for the content of magnesium, potassium, sodium, calcium, phosphorus, chlorine, zinc, copper, iron, lithium and lead. The most important factor is nutrition. The subjects, except 79 healthy controls, were fed in residential accomodation, so they received almost the same meals in their institution. Psychiatric patients and mentally handicapped received drugs from the same group - psychotropic drugs, they stayed in the same accomodation and microclimate, their lifestyle was also similar (little exercise, little fresh air) and therefore they had a limited oportunity to obtain vital elements from surrounding environment. They were not much exposed to heavy metals in their environment, so the content of lead is much lower than in the studies by other authors from more industrialized areas. In the mentally handicapped, decreased contents of magnesium and calcium were found in serum and hair, the content of copper was lower than in the controls, but the content of iron was higher. The content of potassium in serum and hair in psychiatric patients was the highest of all subjects, which may be important for diagnosis.
The field trials were conducted in the years 2007–2009. Examined herbicide mixtures contained Betanal Progress 274 OF, Lontrel 300 SL and adiuvant Trend 90 EC, this was supplemented with Goltix 70 WP, Flirt 460 SC or Venzar 80 WP. The components of mixtures in two reduced doses (by 50% and 67%) were applied. The conducted trials indicated that examined microrate systems did not significantly differentiate the level of sugar and melassogenic contents in sugar beet roots. The sum of all detected residues amounted to 0.0022–0.0149 mg/kg. The highest levels of residues in the case a application of Betanal Elite 274 EC in full rates were detected. The examinated mictorate herbicide systems lower residues level were characterized. Rate reduction in these systems caused in general a significant decrease of residues.
Stosując płomieniową metodę ASA oznaczano zawartość sodu w zębach, żuchwie i surowicy krwi zwierząt doświadczalnych: grupy kontrolnej, sztucznie operowanej, po usunięciu jajników oraz po zastosowaniu estrogenowej terapii zastępczej (17ß-estradiol). W indukowanej hypoestrogemii poziom sodu zarówno w zębach jak i w żuchwie obniżył się. Również zawartość sodu w surowicy krwi była niższa od poziomu Na w grupie kontrolnej. Zastosowanie 17ß-estradiolu zapobiegło procesowi demineralizacji badanych tkanek narządu żucia.
The content of magnesium in the blood serum or hair was determined in 88 patients using atomic spectrometry, and the content of magnesium, potassium, sodium, calcium, chlorine, phosphorus in the blood serum and magnesium, potassium, sodium, calcium, zinc, copper, iron, lithium, lead in their hair of 300 patients. When a considerable magnesium deficiency was revealed in blood serum and hair in 28 mentally handicapped males with increased aggression, restlessness, psychomotor excitation and coexisting epilepsia, a 1-month supplementation was administered, which resulted in a considerable improvement in the social functioning in 17 patients. The remaining 11 patients who did not show improvement after the first supplementation, were given the second 2-month supplementation, which resulted in the expected considerable improvement.
