The aim of the study has been to determine the effect of some substances such as dolomite, loam, compost, pinewood bark, peat, lime, charcoal, natural and synthetic zeolite on reducing the impact of soil contamination with arsenic on the content of manganese in some plant species. The content of manganese in the test plants depended on the degree of soil contamination with arsenic, application of different substances as well as on the plant species and organ. Soil contamination with arsenic caused either an increase or a decrease in the content of manganese in plants depending on a plant species and organ. In the series without soil amending substances, in the arsenic contaminated objects the manganese content decreased in above-ground parts of cocksfoot and swede but increased in above-ground parts and roots of maize and yellow lupine, in roots of cocksfoot and swede and in straw and roots of spring barley. On the other hand, the highest rates of arsenic depressed the content of manganese in roots of cocksfoot, swede and spring barley. Addition of any of the aforementioned substances to contaminated soil changed the content of manganese in the plants. The most unambiguous effect of the different substances was determined in the case of above-ground parts of maize as well as above-ground parts and roots of cocksfoot, in which the manganese content fell down, and in roots of yellow lupine, grain and straw of spring barley, in which the content of manganese rose. Charcoal and loam caused the largest and synthetic zeolite led to the smallest changes in the content of manganese in plants.

Manganese contents in various extracts (2 M HN03, 0.05 M EDTA and 0.01 M CaCl2) and total Mn content in soil samples of various soil types from 6 regions of Slovakia were determined. After simulated loading the Mn extraction in 2 M HN03 decreased in order Lgp > Hcf > Jc Chc > Lga > Rc. The same order was also in 0.05 M EDTA and 0.01 M CaCl2. The results showed that Mn extractability is significantly determined by physicochemical soil properties (soil reaction, humus content and quality). Acid soils with a low humic acid content and high fulvoacid content appeared to be the highest risk soils.

Manganese is a component and cofactor for many important enzymes. In blood Mn is complexed to transferrin, and it quickly passes through the body to be extracted mainly in the bile and urine. Almost all Mn pool in blood is located in erythrocytes. Content of manganese in serum, erythrocytes, and hair of 26 men, workers of an airport, was determined. The control group consisted of administrative workers and the test group was composed of airplane servicemen. Hair samples of 0.5 g and 3-4 cm in length measured from the scalp were taken from some places on a head, washed with a detergent solution, rinsed with deionized water, acetone, and dried. Samples of blood were spun. All the samples were mineralized in a mixture of spectrally clean acids HNO3 and HClO4. Concentration of Mn was analyzed by electrothermal atomic absorption spectrometry GFAAS. The concentrations of Mn in the samples of erythrocytes were statistical significantly higher in the test group. In samples of hair, Mn concentrations were comparable between both groups of men. The coefficients of correlation between Mn concentrations in serum and hair, erythrocytes and hair, and between serum and erythrocytes did not imply significant correlations between Mn concentration in the analyzed clinical samples. In contrast, in the erythrocytes of men exposed on aviation fuel the content of Mn was significantly higher.

A two-factorial field experiment in a randomized subblock desing was performed in the years 2001-2003 on light soil. The aim of reasearches was qualification of fertilization of winter rye and of liming intervention's influence on formation of mobility manganese content (1 mol HCl-dm-3) in the soil and on the concentration and removal of this element from tested cultivars' yield. Balanced NPK fertilization (N - 90, P - 30, K - 72 kg-ha-1) was applied with and without liming (CaO 1.76 t-ha-1). The following fertilizers were applied: single-component fertilizers - ammonium nitrate (presowing fertilization), urea (top-dressing), triple superphosphate, 56% potassium salt; multi-component fertilizers - Polifoska 8, Polimag 305, Luboplon and Lubofoska. The soil after harvest of rye characterised with middle abudance in available manganese and according to cultivar fluctuated aproximatety from 121 to 151 mg Mn-kg-1. Although limmng interventions reduced the amount of this form of manganese it hasn't changed its class of resources. The last contents of manganese was stated in grain of hybrid cultivar Ursus F1, more in grain Dankowskie Złote and Nawid F1. Similar tendency showed concentration of manganese in rye straw. on removed manganese from plants' crop had influence both liming and cultivar. From testd cultivars the least of component was drawn by rye Dankowskie Złote - 175 g, more Ursus - 181 g and Nawid - 197 g Mn per ha.

In pot experiments with lettuce, the effect of chelated and mineral forms of manganese on the fresh matter of plants and on the content of Mn, Cu, Zn and Fe in lettuce leaves were compared. Lettuce plants were grown in a peat substrate where the manganese content was differentiated in four levels: 10, 20, 30, and 60 mg Mn‧dm⁻³. Independent of the form of the applied manganese, no differences were found in fresh matter of lettuce heads at manganese levels of 10 to 30 mg Mn‧dm⁻³ substrate. When the plants were nourished with the mineral form of manganese, then in comparison with the chelated form of manganese, the content of manganese in lettuce leaves was higher. The differentiated fertilization with manganese exerted an effect on the nutritional status of plants with copper, zinc and iron. After the application of chelated manganese, there was more copper and iron in the lettuce, but a lesser amount of zinc than in case of manganous sulphate application. The increase of manganese content in the substrate caused an increase of this component in the plants.

The impact of mineral fertilization with or without multi-component fertilizers on the content of microelements in soil and spring triticale grains was investigated in field trials, in 2009-2011. The experiment was carried out on 8 fertilizing treatments with three replications, which included two varieties of spring triticale: Andrus and Milewo. The content of available zinc and manganese was higher on plots cropped with the cultivar Andrus and nitrogen fertilization with urea or with urea and ammonium nitrate. It was also found out that the content of available manganese, zinc and iron in the analyzed soils was within the natural average range. A higher content of manganese and zinc in grains was detected after the application of multi-component fertilizers. Nitrogen fertilization at a dose of 120 kg.ha-1 together with Azofoska and Ekolist resulted in an increase in the iron content in cv. Andrus. The regression analysis between the content of the analyzed microelements in soil and in triticale grains revealed a significant increase in the iron, manganese and zinc content in grains together with an increase in the content of these elements in soil under cv. Milewo. With respect to the zinc content in soil and in grain from this variety, the coefficient of determination was the closest to the coefficient of a linear correlation (R2 = 0.9105). It was shown that an increase in the content of microelements in soil was not always accompanied by an increase in the content of these elements in spring triticale grains.

The aim of the study was to analyze the total content of micronutrients in the soils in some habitats in the area of the Jezierzyca River Valley Landscape Park. Experimental sites were chosen with regard to different habitats (humid mixed coniferous forest, fresh mixed coniferous forest, humid mixed forest, fresh mixed forest). There are arenosoils, rusty and podzol soils and gley soils. The soils were developed from the river alluvial sands and fluvial sands and prove the acidic reaction. Results showed that the total content of Mn, Zn and Cu is highest in the organic levels and decreases with the depth in the analyzed soils. Only in the podzols soils the total content of Mn decreases in the eluvial horizon and increases in the iluvial horizon. The conducted investigations indicate no pollution of the soils with the micronutrients. The exception was a higher content of Cu in the superficial level of soils in humid and fresh mixed coniferous forest.

Research on grasslands is conducted to assess the yielding potential and determine changes of sward quality depending on applied fertilization. Therefore, the present study was undertaken to assess the contents of manganese, nickel and iron in soil and meadow sward shaped under the influence of diversified mineral fertilization and liming. The experiment is established in the village Czarny Potok near Krynica, about 720 m above sea level., at the foot of Mount Jaworzyna Krynicka. The experiment was set up in 1968 on a natural mountain meadow of mat-grass (Nardus stricta L.) and red fescue (Festuca rubra L.) type with a large share of dicotyledonous plants. Total content of manganese, nickel and iron was determined in the plant and soil material after sample mineralization in a muffle furnace. The studied were extracted with 0.025 mol·dm-3 NH4EDTA solution and the content of Mn, Ni and Fe in the solutions was assessed with the ICP-AES method. The content of total forms of manganese was higher in the soil of the limed series. The soil reaction significantly affected amounts of this element extracted with NH4EDTA solution. Soil liming limited manganese bioavailability and improved the forage value of the analyzed biomass. Small quantities of nickel bound to the soil organic substance were found in the analyzed soil, which suggested considerable mobility of this elements and its translocation into deeper levels of the soil profile, beyond the reach of the plant root system. Liming increased the content of iron forms in combinations with the soil organic substance. Iron deficiency in the meadow sward may have a physiological basis such as difficult iron transport from the root system to aerial plant parts, but it was not caused by limited iron uptake from soil.

The aim of the study was to determine the effect of inoculation of Virginia mallow (Sida hermaphrodita [L.] Rusby) with fungus Sclerotinia sclerotiorum [Lib.] de Bary, which causes stem rot, on the contents and distribution of aluminium, manganese and iron in the shoots of this plant. Field study was carried out during three years (2011-2013) in the soil and weather conditions of central-west Poland. Inoculation was carried out with isolates obtained from rapeseed and mallow. It consisted in a slight damage of stem epidermis and inserting wheat grain overgrown with mycelium of a given isolate. During plant growth, strong infection of mallow shoots was observed, which caused inhibition in the growth and development of the plant. At the stage of technological maturity, shoots were harvested from both the control and inoculated plots for chemical analyses. Contents of the studied elements were determinated in analytical solutions obtained from biomass ash after its “dry combustion” method, using ICP-OES spectrometer. Contents and distribution of aluminium, manganese and iron in mallow shoots depended upon plant parts and placement of pathogens on the stem. The highest amount of aluminium was found in the inoculated part, and the lowest in the apices part, regardless of isolate origin. In the case of iron and manganese distribution, statistically significant effect of the applied pathogen was found. Isolate from the mallow caused greater manganese accumulation and lower iron accumulation. The conducted study demonstrates a significant effect of infection with fungus S. sclerotiorum on the physiological processes that occur in Virginia mallow plants.

The aim of the research was to estimate the impact of manure, municipal sewage sludge and compost prepared from municipal sewage sludge on crop yield and content of microelements (Mn, Zn, Cu, Ni) as well as Pb, and Cd in spring rape and spring triticale and also to specify the bioaccumulation indexes of microelements in test plants. A pot experiment was set up in the Vegetation Hall of the University of Agriculture in Szczecin 2006. Manure, raw sewage sludge and compost prepared from sewage sludge with the GWDA method were used. The pot experiment was set up with the split plot method in three repetitions. Objects of the first factor were types of fertilizers (manure, municipal sewage sludge and compost prepared from sewage sludge) and objects of the second factor were the doses of individual fertilizers introduced to soil in conversion to the amount of incorporated nitrogen (85 and 170 kg N⋅ha-1 i.e. 0.26 and 0.52 g N per pot). The results indicate that the best yields of spring rape seeds and spring triticale grains were obtained from the object fertilized with a double dose of sewage sludge. Fertilization with manure, sewage sludge and compost prepared from sewage sludge increased the content of microelements as well as Pb and Cd in seeds and grains of the test plants. These contents did not exceed permissible values for industrial plants. The calculated bioaccumulation indexes of microelements indicate that spring rape and spring triticale were accumulating moderate amounts of manganese and zinc.

Serum, livers and kidneys of 30 silver foxes from one breeding farm were subjected to analysis of the four microelements contents. The samples derived from 3 groups of animals (An=10) selected according to age and developed reproduction disorders. Cu, Cr and Mn were determined by a graphite furnace AAS whereas Zn by the flame AAS methods. Serum levels of Zn were the least variable (×(n=30)=4.72 ± 2.313 μg ·mL-1) and the mean of Cu content was 0.26 ± 0.244, of Cr was 0.029 ± 0.032 and of Mn was 0.074 ± 0.085 μg ·mL-1. The livers and kidneys contained respectively: 159.9 ± 23.66 and 74.25 ± 14.44 μg g⁻¹ of Zn; 34.03 ± 12.43 and 13.66 ± 1.67 μg g⁻¹ of Cu as well as 6.28 ± 0.97 and 2.60 ± 0.33 μg g⁻¹ of Mn. The most variable was Cr level achieving 1.00 ± 1.06 and 1.43 ± 2.64 μg g⁻¹ (all results per gram of wet weights). The differences between means and medians within the age groups did not exceed 41%, however chromium was an exception, its values differed more than 2 times. High zinc level found both in the serum and the organs resulted from its concentration in feedstuff being 1040,5 μg g⁻¹, exceeding the recommended level for farming foxes. Over-supplementation of dietary Zn might suggest connection between subtoxic action of Zn or its interaction with Cu or Cr followed by subsequent effect on reproduction events. Whether nature of Zn effects derived from direct target action or from Zn – Cu or Zn – Cr interactions have to be solved experimentally. Some foxes contained copper and chromium in livers and kidneys at levels exceeded significantly those concidered as physiological ranges for mammals, whereas manganese was within these limits. Thus, manganese was considered to keep homeostasis status of this element in the examined foxes.
