Opis:
Background. In addition to N, P and K, S is a valuable plant nutrient that determines the size, and quality of harvested crop yields. Its deficiency leads to lower yields of plants and deterioration of their quality parameters. Material and methods. The research was aimed to determine the effect of S fertilizer in various forms on the content of this component ($S$tot and $SO_4 -S$) in the dry matter (DM) of tested plant species: spring wheat (Triticum aestivum L.), white mustard (Sinapis alba L.), spring oilseed rape (Brassica napus L. var. napus), spring barley (Hordeum vulgare L.) and orchard grass (Dactylis glomerata L.). The study was performed based on a strict three-year pot experiment. The variable factor was S applied in seven different forms, plus the control – without S fertilization. The subject of the research were treatments: the control – without S fertilization (1); RSMS – sulphate-urea solution with addition of $Na_2 S_2 O_3·5H_2 O$ (2); $(NH_4 )_2 SO_4$ (3); $K_2 SO_4$ (4); $Na_2 SO_4$ (5); elemental sulphur (S-S°) (6); $CaSO_4·2H_2 O$ (7); $H_2 SO_4$ (8). Results. The highest content of total sulphur occurred in the vegetative and generative parts of spring wheat fertilized with sulphur in the form of RSMS. In barley and orchard grass, similar trends were found after the application of $K_2 SO_4$, $H_2 SO_4$ and $CaSO_4·2H_2 O$. The most favourable form of sulphur applied for the total sulphur concentration in the vegetative parts of white mustard and spring oilseed rape was RSMS, for white mustard seeds – S-S° and $H_2 SO_4$, while for the generative parts of spring oilseed rape – $K_2 SO_4$. Among the used forms of S nutrition, the largest impact on $SO_4 ^(2-)-S$ content was exerted by this component application as RSMS (in spring wheat, white mustard seeds, spring barley grains), $K_2 SO_4$ (straw of white mustard, seeds of spring oilseed rape) and S-S° (straw of spring barley, orchard grass). Conclusion. Among the sulphur forms used, the largest amounts of total sulphur were found in the dry matter of the tested plants in which RSMS, $K_2 SO_4$, $H_2 SO_4$ and $CaSO_4·2H_2 O$ were used in cultivation. However, in the case of sulphate sulphur, this referred to the use of RSMS, $K_2 SO_4$ and S-S°.
Siarka obok azotu, fosforu i potasu jest cennym składnikiem pokarmowym roślin, który decyduje nie tylko o wielkości, ale również jakości plonów roślin uprawnych. W związku z tym, celem podjętych badań była próba określenia wpływu siarki pochodzącej z różnych źródeł na zawartość tego składnika ($S_(og)$. i $S-SO_4$) w suchej masie badanych gatunków roślin: pszenicy jarej (Triticum aestivum L.), gorczycy białej ( Sinapis alba L.), rzepaku jarego (Brassica napus L. var. Napus), jęczmienia jarego (Hordeum vulgare L.) i kupkówce pospolitej (Dactylis glomerata L.). Badania przeprowadzono w oparciu o ścisłe trzyletnie doświadczenia wazonowe. Czynnikiem zmiennym była siarka użyta w siedmiu różnych formach. Badania obejmowały obiekt kontrolny – bez nawożenia siarką (1) oraz obiekty traktowane związkami siarki: RSMS – roztwór saletrzano-mocznikowy z dodatkiem $Na_2 S_2 O_3·5H_2 O$ (2); $(NH_4)_2 SO_4$ (3); $K_2 SO_4$ (4); $Na_2 SO_4$ (5); siarka elementarna (S-S°) (6); $CaSO_4·2H_2 O$ (7); $H_2 SO_4$ (8). Najwyższą zawartością $S_(og)$. charakteryzowały się wegetatywne i generatywne części pszenicy jarej nawożonej siarką w postaci RSMS. W przypadku jęczmienia i kupkówki pospolitej podobne tendencje stwierdzono po zastosowaniu $K_2 SO_4$, $H_2 SO_4$ i $CaSO_4·2H_2 O$. Najkorzystniejszą formą nawożenia siarką w przypadku zawartości siarki całkowitej w wegetatywnych częściach gorczycy białej i rzepaku jarego było stosowanie RSMS, dla nasion gorczycy białej – siarki elementarnej i $H_2 SO_4$, natomiast dla generatywnych części rzepaku jarego – użycie $K_2 SO_4$. Wśród zastosowanych form nawożenia siarką największy wpływ na zawartość $S-SO_4$ wywarło stosowanie tego składnika w postaci RSMS (w przypadku pszenicy jarej, nasion gorczycy białej i ziarna jęczmienia jarego), $K_2 SO_4$ (słoma gorczycy białej, nasiona rzepaku jarego) i siarki elementarnej (słoma jęczmienia jarego, kupkówka pospolita).

Opis:
A three-year field experiment was conducted in Byszwałd near Lubawa in 2000-2002. The aim of this study has been to determine the influence of increasing rates of sulphur on the dynamics of available phosphorus in soil at two horizons: 0-40 and 40-80 cm. The trial was set up on acid brown soil of the granulometric composition of heavy loamy sand. The initial soil had the following properties: pH(KCl) = 5.30, mineral nitrogen 24.0, sulphate sulphur 4.10, available phosphorus 34.5 and potassium 110.0 mg kg-1 of soil. Three levels of sulphur fertilization were applied: 40, 80 and 120 kg⋅ha-1 in the sulphate form (S-SO4) and as elementary sulphur (S-S0). During the whole duration of the field trials, the results demonstrating the effect of fertilization with different forms and rates of sulphur on the content and transfer of available phosphorus in soil were inconsistent. Only the dose of 120 kg⋅ha-1 S-SO4 caused a significant increase in the concentration of available sulphur in soil in the 0-40 and 40-80 cm layers. All the rates of elementary sulphur as well as 40 and 80 kg⋅ha-1 sulphate sulphur caused little less but an increasing tendency in the content of phosphorus in soil. The effect of elementary sulphur became apparent as late as the third year of the trials. The effect of the doses of 40 and 80 kg⋅ha-1 of sulphur on properties of soil depended on the form of sulphur, duration of the experiment.
W latach 2000-2002, w Byszwałdzie, w pobliżu Lubawy, przeprowadzono 3-letnie doświadczenie polowe. W doświadczeniu badano wpływ nawożenia siarką na dynamikę przyswajalnego fosforu w glebie w dwóch poziomach: 0-40 cm i 40-80 cm. Eksperyment założono na glebie brunatnej, kwaśnej o składzie granulometrycznym piasku gliniastego mocnego. Gleba wyjściowa miała następujące właściwości: pH(KCl)=5,30, azot mineralny 24,0, siarka siarczanowa 4,10, przyswajalny fosfor 34,5, potas 110,0 mg⋅kg-1 gleby. Zastosowano 3 poziomy nawożenia siarką: 40, 80 i 120 kg⋅ha-1 w formie siarczanowej (S-SO4) i elementarnej (S-S0). W ciągu całego okresu badań otrzymano niejednoznaczne wyniki dotyczące wpływu nawożenia różnymi formami i dawkami siarki na zawartość i przemieszczanie się przyswajalnego fosforu w glebie. Jedynie dawka 120 kg⋅ha-1 S-SO4 przez cały okres badań wpływała na uruchamianie i migrację fosforu glebie oraz spowodowała istotne zwiększenie zawartości przyswajalnego fosforu w glebie w warstwie 0-40 cm i 40-80 cm. Wszystkie dawki siarki elementarnej oraz 40 i 80 kg siarki siarczanowej powodowały jedynie tendencję zwyżkową. Wpływ siarki elementarnej uwidocznił się dopiero w trzecim roku doświadczenia. Działanie dawek 40 i 80 kg⋅ha-1 siarki na właściwości gleby zależało od formy siarki oraz czasu trwania doświadczenia.

Opis:
The aitn of the research was to evaluate the influence of the metallurgy-sulphur railroad (LHS) on some soil properties of the Roztoczański National Park. Special attention was paid to sulphur risks, due to sulphur transport that way, although in smaller quantities as compared to the previous decade. The study Was based on the analysis of basic properties of selected soils and content of total and sulphate sulphur in soif samples taken in 2 cross-section profiles, located 400 and 900 m from the border of the Park and 50, 100, and 150 m from the rails; from 3 levels of forest soils; litter, 0-10 cm, and 30-40 em. Pedological survey indicated that within the study area predominated light soils. They are derived from river sands (mainly gley, gley-podzolic, podzolic soils, and black earth), and contain low amounts of the fine fraction. It was found that the line, which runs across the protected areas of the national park, does not exert nowadays a direct negative influence on the investigated soil properties (C-organic, reaction, mobile aluminium). The amount of total and /sulphate sulphur reniainjjon the level characteristic for such soil types in natural environment. No decrease in the content of both forms of sulphur was found along with the distance of sampling points from the LHS rails.

Opis:
Nowadays, sulfur is considered one of the primary resources of the chemical industry, most of which is produced as a refinery by-product during the processing of oil and natural gas. Sulfur production volumes are increasing every year, while the demand for it does not always match the growing supply, which leads to a serious problem of sulfur surplus in the world market. Granulated sulfur – the main commercial type of elemental sulfur – is transported in large quantities both by land and sea and can have a negative impact on the environment. At the moment, the issue of the negative impact of granulated sulfur on the environment has not been fully studied, which determines the relevance of this research. This review article presents the global market of granulated sulfur, paying attention to its safe transport – from the producer to the consumer. The potentially harmful factors of the impact of sulfur handling on elements of the natural environment, such as atmospheric air, water reservoirs, soil and vegetation, were also taken into account.

Opis:
The work aims to assess the degree of soil sulphur contamination of the various abandoned reclamation efficiencies, within the microhabitats formed in the “Jeziórko” inoperative boreholes of former sulphur-mining areas. These areas have been reclaimed to the forest. Three plot categories were initially determined in the post-mining areas: category D – degraded, i.e. ineffectively reclaimed and unsuccessfully afforested plots, with low cover-abundance or complete lack of vegetation, pine stands category, category (P) – birch stands and category (B) – successfully afforested. Afterwards, four circular plots were defined within each of the determined categories (4 replications, i.e. a total of 12 plots). For each plot, cover-abundance (according to the Braun-Blanquet scale) and dominant herbaceous vegetation species, tree species and stand density were determined. Height (Ht) and diameter at breast height (DBH) measurements were taken, and a vitality assessment was completed, according to the IUFRO classification. Soil samples were collected at each plot, in five points, at two different depths (0–5 cm and 5–40 cm). Finally, laboratory analysis was undertaken. Soil properties such as texture, pH, electrical conductivity (EC), hydrolytic acidity (Hh), the contents of soil organic carbon SOC, total nitrogen TN, total sulphur TS, and exchangeable cations (Ca2+, Mg2+, K+, Na+) were determined. Soils from the D plot category were characterised by high sulphur contamination, excess salinity (EC) and strong acidity in top soil. These parameters indicated that completed neutralization was not performed effectively at certain sites. Pine (P) and birch (B) stands categories showed good growth rates and soil parameters, indicating that the reclamation treatments were completed successfully.

Opis:
This study presents the development of a composite electrode material for lithium–sulphur (Li–S) batteries, combining MOF-74 with carbon black and sulphur. The MOF-74 structures, incorporating Ni(II), Mg(II), and Fe(II) metal ions, were synthesized via a solvothermal method and used to encapsulate sulphur. The microporous nature of MOF-74 facilitates the physical confinement and storage of sulphur, potentially enhancing the performance of Li–S batteries. The investigation focuses on how different central metal ions in MOF-74 influence the performance of sulphur-based electrodes. Among the metal ions studied, Fe(II) and Mg(II) were selected for their low toxicity, cost-effectiveness, and availability, while Ni(II) was included for its high catalytic properties. The materials were thoroughly characterized using infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, powder X-ray diffraction, elemental analysis and X-ray photoelectron spectroscopy. The thermal stability and textural properties of the materials were assessed, showing that MOF-74(Mg) exhibited the highest stability, followed by MOF-74(Ni) and MOF-74(Fe). Nitrogen adsorption/desorption measurements indicated that the specific surface area and pore volume varied with activation temperature, impacting the material’s performance. Among the tested materials, MOF-74(Ni) exhibited the strongest interaction with sulfur, as confirmed by XPS analysis. Electrochemical tests revealed that the S/MOF-74(Ni) electrode demonstrated superior stability and capacity retention with a minimal capacity fading rate of 0.001% per cycle over 200 cycles, achieving a reversible capacity of $465 mAh g^{−1}$ and a capacity retention of 99.75%. In contrast, the S/MOF-74(Fe) electrode showed significantly reduced performance. A structure–performance correlation was established to assess sulfur interaction, electrode stability, and degradation behavior. Overall, the results highlight that MOF-74(Ni) offers the most promising performance due to its effective sulphur immobilization and superior electrochemical properties compared to MOF-74(Mg) and MOF-74(Fe).

Opis:
Shipping emits a variety of air pollutants: sulphur dioxide (SOx), nitrogen oxides (NOx ), carbon dioxide (CO2 ) and particulate matter PM. Air pollutant emissions from maritime transport can be transported over long distances and thus increasingly contribute to air quality problems. Key environmental regulations (international and European) coming into force in this decade address emissions of SOx , NOx , CO2 and PM to control and limit their impact in the atmosphere. In the European Union, accordingly to the legal regulations, in the sulphur emission control areas the required SOx content of fuel will be reduced from 1.5 % to 0.1 % beginning January 2015. Globally, from 2020 onwards, ships operating in all other European Sea areas will have to use fuels with sulphur content of 0.5 % or less.

Opis:
A new method for description of thermodynamic properties of Cu-S mixtures is put forward. The basic feature of this method is the assumption that the activity coefficient of sulphur dissolved in liquid copper is equal to 1 for infinite dilute solution (y[S] = 1 for x[S] = 0). In consequence the following relationships were established: 1. The equilibrium constant for the reaction of sulphur dissolution in liquid copper (0.5S2 (g) = [S] Cu ): [wzór]. 2. Non-temperature dependence of the activity coefficient of sulphur dissolved in the copper-reach liquid (Liquid I): lnγ[S] =-18.25 · x[S] . 3. The chemical potential of the sulphur dissolved in copper in infinite dilute solution: [wzór]. 4. Non-temperature dependence of the activity of sulphur in Cu-S sulphur-rich liquid (Liquid II) – Fig. 6. 5. Non-temperature dependence of the activity of copper in Cu-S sulphur-rich liquid (Liquid II) – Fig. 7. 6. The equilibrium constant for the reaction of sulphur removal from liquid copper ([S] Cu + 2[O] Cu = SO2 (g)): [wzór].
