The more intensive growth of agricultural crops adding mineral fertilizers, environmental pollution make the soil degraded: reduce the fertility of soil, increase the concentration of heavy metals. Especially dangerous is a common, synergistic effect of heavy metals. Vermicompost optimizes pH, texture and organic material content – the soil indicators, which are the major contributors to migration of heavy metals in the soil and to the plants from it. In the article there is an investigation of vermicompost influence on bioaccumulation of heavy metals in common meadow-grass. After experimental research it is determined that immobilization of heavy metals was the best in soil-vermicompost substrate, prepared in a ratio 1:2. The cadmium (Cd) concentrations were lowest and the difference of HM content determined between roots and shoots was the most in biomass grown up in that mixture. In the underground part of plant the concentration equal to 11.10 mg/kg and in the part of above ground – 1.05 mg/kg. The situation of lead (Pb) and copper (Cu) is analogous. This is the optimal ratio of mixture preparation. Intensyvesnis žemės ūkio kultūrų auginimas, tręšiant mineralinėmis trąšomis, aplinkos tarša nualina dirvožemį: sumažėja dirvožemio derlingumas, didėja sunkiųjų metalų koncentracijos. Ypač pavojingas bendras, sinergetinis sunkiųjų metalų poveikis. Vermikompostas optimizuoja dirvožemio pH, granuliometrinę sudėtį, organinės medžiagos kiekį – rodiklius, nuo kurių labiausiai priklauso sunkiųjų metalų migracija dirvožemyje ir iš jo į augalus. Straipsnyje nagrinėjama vermikomposto įtaka sunkiųjų metalų bioakumuliacijai pievinėje miglėje. Atlikus eksperimentinį tyrimą nustatyta, kad geriausiai sunkiuosius metalus „surakino“ dirvožemio-vermikomposto substratas, paruoštas santykiu 1:2. Tame mišinyje užaugintoje biomasėje kadmio (Cd) koncentracijos buvo mažiausios, o skirtumas tarp SM kiekio nustatyto šaknyse ir ūgliuose didžiausias. Požeminėje augalo dalyje koncentracija lygi 11,10 mg/kg, o antžeminėje – 1,05 mg/kg. Švino (Pb) ir vario (Cu) atvejais situacija yra analogiška. Tai optimalus mišinio ruošimo santykis.

Heavy metals over acceptable limits established by the world health organization can source complications to human beings and animal life in the environment. Several analytical approaches have been established to screen the air, water, food quality by tracing different heavy metal ions in samples. The review work begins with the introduction of pharmaceutical analysis, including metal's effect on the body and various instruments used in the heavy metal determination. The potential of ICP-OES to sense heavy metal ions was discussed. This review article provides an impression of the metals present in the environment and their detection through ICP-OES. In addition, recapitulates the body of work on heavy metal determination in the previous years using ICP-OES. The strengths and limitations of ICPOES have also been conversed. The review illustrates that ICP-OES has great prospective in heavy metal ion determination. Keywords: ICP-OES, Heavy elements, Multi-element determination, Plasma, Metals

The article deals with the application of optimal portfolio theory and pair trading theory on the metals futures market. Advantages of the futures market over the spot market include relatively small initial price, low transaction costs, and high volatility. The main aim of the study is to explore the potential of both strategies for effective trading. The following financial instruments were chosen as the inputs of the models: futures on industrial metals (aluminum, copper, nickel, zinc, lead, tin), futures on precious metals (gold and silver). When building the optimal portfolio, it was decided to include Dow Jones Index futures and S&amp;P Index futures among metals. This is because these instruments are extremely volatile and may play the role of a hedge in the portfolio. A drawdown indicator was used to assess the effectiveness of each strategy. The results show that both strategies can be applied on the real-life market. The final choice will depend on the level of risk taking by investors and the desired value of return.

Heavy metals in organic fertilizers pose a risk to the agricultural ecosystem. The environmental risk of heavy metals depends not only on the total amount but also on the speciation. Hence, more information on heavy metals speciation in organic fertilizers is needed to avoid adverse effect. At present, the speciation information of heavy metals is usually obtained by the single-extraction method and sequential extraction method. Common heavy metals that have received attention include Cu, Zn, Pb, Cd, Cr, Hg and As. There is a lack of reviews on speciation analysis methods for heavy metals, specifically in organic fertilizers. This work aims to comprehensively review the methods, explore the problems of the sequence extraction procedure and summarize the factors affecting the distribution of heavy metals speciation. Each sequence extraction procedure of heavy metals in organic fertilizers is described in detail, and the affecting factors are proposed. The review could contribute proposing the directions of optimizing the sequence extraction procedure of heavy metals in organic fertilizers in the future.

Проведен анализ огнетушащих составов, применяемых для тушения активных металлов (пожары класса D). Отмечено, что основные современные средства обеспечения пожаротушения представляют собой галогенсодержащие соли (фториды или хлориды щелочных и щелочно-земельных металлов), препятствующие доступу кислорода без ингибирующего эффекта по отношению к самому горящему металлу. При этом данные солевые композиции не лишены недостатков из-за их высокой гигроскопичности (содержания кристаллизационной воды), что усложняет тушение. Ввиду последнего разработка более эффективных огнетушащих составов для тушения активных металлов является достаточно актуальной и перспективной. Ignition of active metals and their alloys often results in significant material damage. This determines the relevance for development of means to eliminate the possibility of ignition of metals and their alloys in zones of their most likely occurrence - during their melting and refining in metallurgical processes, in the technological processes of their processing and manufacturing of products by enterprises of various industries. For these purposes it is necessary to equip both consumers and special fire departments with highly effective means to ensure fire safety. Burning of active metals is characterized by a very rapid development of the oxidation reaction in the air due to their high reactivity. At the same time, for example, in a D1 class fire (burning of light metals except alkaline), the upper temperature threshold can reach 3000 °C. Alkaline and alkaline-earth metals are able to sustain combustion with limited air oxygen or contact with nitrogen or oxygen-containing substances. Extinguishing metals and their compounds differs from extinguishing fires of other classes. The main extinguishing agent used at protection facilities is a special purpose extinguishing powder. Class D fire extinguishing with a special purpose extinguishing powder consists in creating a protective layer on the burning surface. The use of calming nozzles practically prevents the formation of the air suspension when applying a fire extinguishing agent to burning area. Thus, the principle of extinguishing metals with powder extinguishing agents is to isolate and interrupt the chain reaction of burning. Despite the sufficient effectiveness of the powder compositions used, there was also identified a number of significant drawbacks in the work: a large consumption of extinguishing agent, the difficulty of supplying extinguishing agent to the hearth due to high temperature, the high cost of special extinguishing powders of a new generation, etc. As a matter of fact, it is concluded that the search for more effective means of extinguishing fires of metals and their alloys is relevant and promising, with the absence of these shortcomings.

For the technology of EBSD, the twinning of metals was described in the form of rotation angle combined with rotation axis, while the twinning of metals was usually described in the form of twinning plane combined with twinning direction. In this report, the corresponding relationship between the two description forms of twinning of face-centered cubic (FCC) metals has been built, based on this relationship, the twinning plane and twinning direction of FCC metals can be determined by EBSD. As the practical application of this relationship above, the twinning variants of two kinds of Ni based superalloys were analyzed.

The paper focusses on analysis of the impact of iron particles on heavy metals migration in the soil within the northern area of Klaipeda city. The city has been chosen due to its function as a transit harbour locating 19 big companies related to the sea business and cargo services. Like every ecosystem, the soil is characterized by accumulating different substances with no exclusion of contaminants. For the analysis of iron impact on heavy metals migration, an experimental stand with six fixed columns was constructed. Copper salt solution was passed through the columns on quartz sand with iron filings (1.5 and 10%) in it and without (the control column). Quartz sand was chosen due to its inert properties. The analysis proves that iron forms a geochemical barrier and it has significant impact on the mode of the heavy metal (Cu) migration in the soil. Santrauka Straipsnyje analizuojama geležies daleliu itaka sunkiuju metalu migravimui šiaurineje Klaipedos uosto dalyje. Klaipeda pasirinkta, nes tai tranzitinis uostas, kuriame vyksta kroviniu krovimas, laivu statyba, rekonstravimas ir visos kitos funkcijos, susijusios su jūrine veikla ir krovininiu laivu paslaugomis. Kaip ir kiekvienoje ekosistemoje dirvožemiams būdingos akumuliacines savybes, juose kaupiasi ivairios medžiagos, kartu – ir teršalai. Geležies itakai sunkiuju metalu migravimui tirti buvo sukonstruotas specialus eksperimentinis stendas su šešiomis kolonomis, pro kurias per tiriama terpe – kvarcini smeli (nes jis yra inertiškas) buvo leidžiamas vario druskos tirpalas. Eksperimente naudotas kvarcinis smelis su geležies drožlemis (1, 5 ir 10 %) ir be ju (kontrolinis). Iš analizes rezultatu akivaizdu, kad geležis turi reikšminga itaka sunkiojo metalo (Cu) migracijos pobūdžiui dirvožemyje bei sukuria geochemini barjera. Резюме Клайпеда – крупный транзитный порт, в котором погрузкой грузов, строительством кораблей и их реконструкцией, а также всеми остальными функциями, касающимися морской деятельности и услуг грузоподъемных кораблей, занимаются 19 больших компаний. Как и каждая экосистема, почва функционирует как накопитель и резервуар материалов, включая и загрязняющие вещества. В статье главное внимание уделено исследованию частиц железа, оказывающих влияние на миграцию тяжелых металлов в северной части города Клайпеды около Клайпедского порта. С этой целью была сконструирована специальная доска с шестью колоннами, через которые в анализируемую среду – кварцевый песок (инертный материал) – пропускался раствор. Для эксперимента был выбран кварцевый песок со стружками железа (1, 5 и 10%) и без него. Результаты анализа показали, что железо оказывает значительное влияние на формы миграции тяжелого металла (меди), а также создает геохимический барьер.

The phenomenon of electrochemical phase formation in metals and alloys via a supercooled liquid state stage was discussed. Assuming the electrodeposited metal to be a product of formation and ultrarapid solidification of supercooled metallic liquid, a possibility of metastable phase formation during electrodeposition of polymorphous metals was suggested. It was anticipated that the polymorphic transition of the metal’s metastable form to the stable one occurs by shear, as does the martensitic transformation. To enable revealing an orientation relationship between grains of the two phases, a method for X-ray texture analysis of metals was developed using a combination of direct pole figures. It was established that the phase formation during electrodeposition of polymorphous metals produces metastable modifications typical of entities that crystallized from a liquid state at extremely high rates. In regards polymorphic transitions in metal electrodeposition, certain orientation relationships were observed between grains of the stable and the metastable phase, which is typical of phase transformations proceeding at extremely high rates. The results obtained provided additional arguments in favor of the phenomenon under discussion.
