Abstract:

Mixed oxides based on Mg-Al, Mg-Fe, Zn-Al, and Ni-Mg-Al were prepared, characterized and used as sorption materials for different types of active pharmaceutical ingredients (APIs)– nicotinic acid, salicylic acid, ibuprofen, paracetamol and ascorbic acid. Immobilization of APIs on solid supports was confirmed using X-Ray diffraction and infrared spectroscopy. Overall, the best sorption material for mentioned substances showed to be mixed Mg-Al oxides (>80 % of immobilized substance after 4 h except ascorbic acid). On the other hand, Mg-Fe and Mg-Ni-Al materials did not possess high sorption capacity (max. 59 % after 4 h). From studied substances, the immobilization amount was the lowest in the case of ascorbic acid (max. 44 % immobilized after 4 h), the highest amount was immobilized in the case of salicylic and nicotinic acids (>95 %, 4 h). The discussion regarding the structure of substances and properties of sorption materials is also offered.

Abstract:

Nodular goiter (NG) is an internationally important health problem. The aim of this exploratory study was to examine the content of silver (Ag), bromine (Br), calcium (Ca), chlorine (Cl), cobalt (Co), chromium (Cr), cooper (Cu), iron (Fe), mercury (Hg), iodine (I), potassium (K), magnesium (Mg), manganese (Mn), sodium (Na), rubidium (Rb), ammonium (Sb), scandium (Sc), selenium (Se), strontium (Sr), and zinc (Zn) in the normal thyroid and in the thyroid tissues with diagnosed colloid NG.. Thyroid tissue levels of twenty chemical elements (ChE) were prospectively evaluated in 46 patients with NG and 105 healthy inhabitants. Measurements were performed using non-destructive energy-dispersive X-Ray fluorescent analysis combined with instrumental neutron activation analysis with high resolution spectrometry of short– and long-lived radionuclides. Tissue samples were divided into two portions. One was used for morphological study while the other was intended for ChE analysis. It was found that during a goitrous transformation the levels of Ag, Br, Cl, Co, Cu, Fe, Hg, Mg, Na, and Sc in thyroid tissue significantly increased, whereas the levels of I and Sr decrease. It was supposed that the changes in levels Ag, Br, Cl, Co, Cu, Fe, Hg, I, Mg, Na, Sc, and Sr in thyroid tissue can be used as NG markers.

Abstract:

Isparta city center is selected as a work area in this study because the public believes that the tap water is dirty and harmful. In this study, the city's drinking water in the distribution system and other spring waters which are used as drinking water in this region were investigated from the point of water quality and health risk assessment. Water samples were collected from major drinking water springs, tap waters, treatment plants and dam pond in the Isparta province center. Ca-Mg-HCO3, Mg-Ca-HCO3, Ca-Na-HCO3, Ca-HCO3, Ca-HCO3-SO4 and Ca-Mg-HCO3-SO4 are dominant water types. When compared to drinking water guidelines established by World Health Organization and Turkey, much greater attention should be paid to As, Br, Fe, F, NH4, PO4 through varied chemicals above the critical values. The increases of As, Fe, F, NH4 and PO4 are related to water–rock interaction. In tap waters, the increases of As and Fe are due to corrosion of pipes in drinking water distribution systems. The major toxic and carcinogenic chemicals within drinking water are As and Br for both tap water and spring water. Also, F is the non-carcinogenic chemical for only spring waters in the study area.

Abstract:

This study is an attempt to evaluate the hepatoprotective activity ofTabernaemontana divaricataagainst DEN and Fe NTA induced liver necrosis in rats. Ethanolic extract of the whole plant ofTabernaemontana divaricataat doses of 200 and 400 mg/kg body weight and 5-fluorouracil (standard drug) was orally administered to male Wistar Albino rats once daily for 24 weeks, simultaneously treated with the carcinogen DEN and Fe NTA. In simultaneously treated animals, the plant extract significantly decreased the levels of uric acid, bilirubin, AST, ALT, and ALP in serum and increased the levels of liver marker enzymes in liver. Treatment with the extracts resulted in a significant increase in the levels of antioxidants accompanied by a marked reduction in the levels of malondialdehyde when compared to DEN and Fe NTA treated group. When compared with 200 mg/kg bw rats, 400 mg/kg bw rats and 5-fluorouracil treated rats showed better results in all the parameters. The histopathological studies confirmed the protective effects of extract against DEN and Fe NTA induced liver necrosis. Thus, it could be concluded that the use ofTabernaemontana divaricataextract in the treatment of carcinogen induced hepatic necrosis.

Abstract:

The exotic flavor of Brazilian tropical fruits led to increased consumption. Consumers awareness regarding balanced diets, makes necessary determining nutritional composition - vitamins and minerals of the fruits ordinarily consumed. This study contributed to the evaluation of macro (K, Ca) and microelements (Mn, Fe, Cu, Zn and Br) in eight exotic Brazilian tropical fruits: "abiu" (Lucuma caimito Ruiz & Pav.), "jenipapo" (Genipa americana L.), "jambo rosa" (rose apple, Eugenia Jambos L.), "jambo vermelho" (Syzygium malaccence L., Merr & Perry), "macaúba" (Acrocomia aculeata Jacq. Lood. Ex Mart.), "mangaba" (Hancornia speciosa), "pitanga" (Brazilian Cherry, Eugenia uniflora L.), and tamarind (Tamarindus indica L.), using the Energy Dispersive X-Ray Fluorescence (EDXRF) technique. "jambo vermelho" and "macaúba" presented the highest values of K concentrations, 1,558 and 1,725 mg 100 g-1, respectively. On the other hand, Ca concentrations were highest in "macaúba" (680 mg 100 g-1) and "jenipapo" (341 mg 100 g-1). The microelemental concentrations in these eight fruits ranged from: 0.9 to 2.0 mg 100 g-1 for Mn, 3.9 to 11.4 mg 100 g-1 for Fe, 0.5 to 1.0 mg 100 g-1 for Cu, 0.6 to 1.5 mg 100 g-1 for, Zn and 0.3 to 1.3 mg 100 g-1 for Br. The amounts of macro and microelements in the eight fruits analyzed were compared to other tropical fruits and it was found that some of them could be classified as rich sources for these macro and microelements.

Abstract:

The marine sediment samples collected from the northeastern Brazilian continental shelf, at water depths between 20 and 80 m, consisted mainly of sands with an almost total absence of gravel and granules. Medium, coarse and very coarse sand grains are mostly composed of halimeda, lithothamnium, rodoliths and bioclastic sands with a carbonate content varying between 77 and 96 %. The chemistry in general shows a decreasing content of Ca (86.1 %) >Si (6 %) > Cl (3.6 %) > Sr (0.8 %) > K (0.66 %) > S (0.62 %) > Al (0.6 %) > Na (0.55%) > Mg (0.43 %) > Fe (0.4 %) > P (0.2 %) > Br (0.04 %) in the samples. There was no correlation between CaCO3 and chemical contents and grain size with depth and bio-components. With the exception of Sr of marine origin, all other elements (P, S, Br, Cl, Fe) are of continental origin. The lithothamnium of some offshore samples shows higher CaCO3 content, while Mg and Na are present only in halimedas. Bioclastic sands contain no Br, and silt and clay fractions are rare and characterize samples closer to the coast. These marine bioclastic granulates are of very pure biogenic calcium carbonates and are thus highly to be recommended for economic purposes.

Abstract:

In this paper, two multielement analysis techniques, Neutron Activation Analysis (NAA) and Total Reflection X-ray Fluorescence (TXRF), are combined to detect elemental concentrations in Barbula indica moss collected at Dalat, Vietnam. Combining these two techniques has improved the qualitative detection of elements due to atmospheric deposition on moss samples. The concentrations of 40 elements, including Na, Mg, Al, Si, P, S, Cl, K, Ar, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Kr, Rb, Y, Sb, I, Cs, Ba, La, Ce, Sm, Eu, Tb, Dy, Yb, Hf, Ta, Pb, Th, and U in the Barbula indicamoss samples collected at 19 locations at Dalat have been determined. It is shown that the air in Dalat is suspected of contamination by Na, Mg, Si, P, S, V, Mn, Cu, Se, Br, and U; slightly contaminated by Mg, Cl, K, Cr, Ni, S, and Ni; moderately contaminated by Sc, Fe, Co, Zn, As, Kr, Rb, Y, Sb, Cs, Ba, La, Ce, Sm, Eu, Dy, Yb, Ta, Pb, and Th; and seriously contaminated by Tb. Factor analysis has been used to explain the contamination sources of these elements, including V, As, Fe, Zn, Se, Rb, Sb, Cs, Al, Cu, and Pb in the investigated area. Four factors have been extracted that can explain 86% of the total variance, and the results suggest that the main sources of atmospheric pollution in Dalat originate from traffic and windblown dust.

O objetivo do trabalho foi avaliar, em casa de vegetação, a capacidade das plantas em oxidar o Fe reduzido (Fe2+) sobre a superfície das raízes, comparando duas variedades de arroz com diferentes sensibilidades ao Fe2+ em solução (BR IRGA 409 e EPAGRI 108) e duas soluções com diferentes concentrações de Fe2+. O delineamento experimental foi completamente casualizado e consistiu de um fatorial 2² com mais um tratamento em branco, no qual as plantas foram mantidas somente em solução nutritiva. Para obter soluções com diferentes concentrações de Fe2+, foram utilizados dois solos (Gleissolo Lâmico e Planossolo Hidromórfico). As plantas foram cultivadas em solução nutritiva completa por 30 dias e, posteriormente, em soluções extraídas dos solos inundados por mais 24 horas. A capacidade oxidativa das plantas foi estimada a partir da quantidade de compostos de Fe acumulados na superfície das raízes. Os cultivares BR IRGA 409 e EPAGRI 108 apresentaram a mesma capacidade de oxidar o Fe2+ sobre a superfície das raízes, não sendo a capacidade de oxidação a variável diferenciadora dos dois cultivares quanto à maior ou menor sensibilidade à toxidez de Fe. A solução do Planossolo, por ser mais concentrada em Fe2+ (280 mg L-1), promoveu maior precipitação de óxidos sobre as raízes do que a solução do Gleyssolo, menos concentrada (118 mg L-1). A camada de óxidos precipitada sobre as raízes do cultivar EPAGRI 108, tolerante à toxidez de Fe, foi menos ativa em adsorver P do que do cultivar BR IRGA 409, considerado sensível.

Abstract:

AbstractIn this work, superficial waters of two small rivers flowing in the São Domingos' abandoned mining area were analyzed in order to infer on soil-water transfer of the elements determined. Instrumental neutron activation analysis was used for elemental concentration assessment. The following elements were found at the mg L−1 level: As, Ba, Co, Cu, Fe, K, Na and Zn. The dry-mass residues varied between 70 mg and 1 g in 20-mL volumes. High enrichment relative to soil was found for most elements. Good statistical associations between Br and Na, between Cr and Sc, and between Ce, Co, Fe, Yb, and Zn, were found, suggesting a similar mechanism of soil-water, elemental transfer. Both the superficial waters' composition and their elemental levels indicate a potential risk of contamination of the underground waters and an actual health risk for the resident populations.

Abstract The concentration of the elements K, Ca, Mg, Na, Sr, Al, As, Ba, Br, Ce, Cr, Fe, Nb, Rb, Se, Sm, V, Zn, Co, Cs, U, Sb, Sc, Th, Eu and Hf in groundwater samples from the eastern phosphate and the southern volcanic area of Syria were investigated using INAA (instrumental neutron activation analysis) and γ-spectroscopy. The concentrations of first and second group elements are higher in the phosphate area than in the volcanic area. The concentrations of Fe, Co, Cr, Sc, Eu and Sm are high in some samples from the southern volcanic area. This can be explained by the occurrence of these elements in surrounding rocks and the solubility of their compounds. The results are compared with drinking water limits from different countries.

Abstract:

The correct assessment of the presence of potentially contaminating elements in soil, as well as in fruits cultivated and harvested from the same places has major importance for both the environment and human health. To address this task, in the case of the Republic of Moldova where the fruit production has a significant contribution to the gross domestic product, the mass fractions of 37 elements (Na, Mg, Al, Ca, Si, K, Mn, Fe, Sc, Ti, V, Cr, Co, Ni, Zn, As, Br, Rb, Sr, Zr, Mo, Cd, Sb, Cs, Ba, La, Ce, Nd, Sm, Eu, Tb, Yb, Hf, Ta, W, Th, and U) were determined by instrumental neutron activation analysis in soil collected from four Moldavian orchards. In the case of three types of fruits, grapes, apples, and plums, all of them collected from the same places, only 22 elements (Na, Mg, Cl, K, Ca, Sc, Mn, Fe, Co, Ni, Cu, Zn, As, Br, Rb, Sr, Sb, Cs, Ba, La, Th, and U) were detected. The enrichment factor, contamination factor, geo-accumulation index, as well as pollution load index were calculated to assess the soil contamination. At the same time, the metal uptake from the soil into fruits was estimated by means of transfer factors. Soil samples showed for almost all elements mass fractions closer to the upper continental crust with the exception of a slightly increased content of As, Br, and Sb, but without overpassing the officially defined alarm thresholds. In the case of fruits, the hazard quotients for all elements with the exception of Sb in fruits collected in two orchards were below unity. A subsequent discriminant analysis allowed grouping all fruits according to their type and provenance.

Abstract:

Spodosols are problem soils due to coarse texture, acid soil reaction, low nutrient status, and low soil moisture retention. About 2.16 million ha of Spodosols (1.1% of the Indonesian land areas) distributed in lowland and highland areas in Kalimantan, Sumatra, Sulawesi, and Papua. Spodosols of the Toba highland areas require special attention because these forested lands are gradually cleared, but then abandoned because they are not suitable for agricultural development, causing land degradation. This study aimed to evaluate mineralogical and chemical characteristics of Toba highland Spodosols, North Sumatra, and their implication on agricultural development. Three pedons of the Toba highland Spodosols from Humbang Hasundutan regency were studied, consisted of soils developed from volcanic sand overlying liparite tuff under the influence of low temperature and high rainfall. Field observation was conducted in January 2008. Fifteen soil samples were collected from the three pedons based on the depth of soil horizon. Results indicated that the formation of these Spodosols were influenced by parent material, high elevation (1676-1821 m) above sea level), and by high amount of rainfall (2167 mm). The Spodosols in Toba highland were still in the early stage of development as characterized by shallow effective soil depth (22-23 cm), domination of weatherable minerals (39-81%) in the sand fraction and dominated by amorphous mineral as shown by sum of A1 + 1/2 Fe extracted by ammonium oxalate as much as 0.6-12.8%. The Spodosols were also characterized by coarse texture (66-95% sand fraction in E and B horizons), high organic-C content (1.4-37.7%), acid soil reaction (pH 3.7- 5.3), very high K2O in Oa horizon (552-933 mg kg-1) and B spodic or C horizon (812-2028 mg kg-1), and low base saturation (< 5%). The existence of biological processes in the surface layer was indicated by accumulation of exchangeable bases (0.88-1.14 cmolc kg-1 in Oa horizon and 0.09-0.25 cmolc kg-1 in B horizon), P2O5 (181-298 mg kg-1 in Oa horizon and 3-24 mg kg-1 in E horizon), and K2O (552-933 mg kg-1 in Oa horizon and 13- 30 mg kg-1 in E horizon). However, these nutrients were easily leached after deforestation. With the sandy texture, loose structure, and no vegetation cover, the erosion hazard is high in the deforested areas. Therefore, lands with Spodosols of the Toba highland, especially are not recommended for agricultural development, rather they should be kept as forest lands.

The moss biomonitoring technique was used for assessment of air pollution in the central part of Georgia, Caucasus, in the framework of the UNECE ICP Vegetation. A total of 35 major and trace elements were determined by two complementary analytical techniques, epithermal neutron activation analysis (Na, Mg, Al, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, Se, B, Rb, Sr, Zr, Mo, Sb, I, Cs, Ba, La, Ce, Nd, Sm, Eu, Tb, Yb, Hf, Ta, W, Th, and U) and atomic absorption spectrometry (Cu, Cd, and Pb) in the moss samples collected in 2019. Principal Component Analyses was applied to show the association between the elements in the study area. Four factors were determined, of which two are of geogenic origin (Factor 1 including Na, Al, Sc, Ti, V, Cr, Fe, Co, Ni, Th, and U and Factor 3 with As, Sb, and W), mixed geogenic–anthropogenic (Factor 2 with Cl, K, Zn, Se, Br, I, and Cu) and anthropogenic (Factor 4 comprising Ca, Cd, Pb, and Br). Geographic information system (GIS) technologies were used to construct distributions maps of factor scores over the investigated territory. Comparison of the median values with the analogous data of moss biomonitoring in countries with similar climatic conditions was carried out.

Abstract:

Cocoa beans are raw materials of cocoa processed food products rich in protein and minerals. Availability of sufficient quantities greatly determines the nutritional quality of the food. One of the post-harvest processes affecting the protein and minerals contents in cocoa beans is fermentation. The purpose of this study was to determine the protein, macro, and micronutrients contents in fermented cocoa beans of PBC 123, BR 25, and MCC 02 clones with fermentation time variations for 24, 48, 72, 96, and 120 hours. Methods of analysis used Kjeldahl and Atomic Absorption Spectrophotometer. The results showed that clones, fermentation time, and their interaction affect protein, macro and micronutrients content in cocoa beans. The interaction between BR 25 clone and 48-hour fermentation time showed the highest protein content (13.34%). The highest macronutrients content were found in PBC 123 clone with 72-hour fermentation time for Ca, in MCC 02 clone with 24-hour fermentation time for Mg, in BR 25 clone with 72-hour fermentation time for Na, and in BR 25 clone with 24-hour fermentation time for K. The highest micronutrients contents were found in PBC 123 clone with 96-hour fermentation time for Fe, in MCC 02 clone with 120-hour fermentationtime for Mn, and in BR 25 clone with 96-hour fermentation time for Zn. Variations of protein, macronutrients and micronutrients contents in cocoa beans were affected by clone variety and fermentation time treatment.

Abstract:

Iron is an essential nutrient for plants. In aerobic conditions, Fe is highly unavailable for plant uptake, and Fe deficiency can be severe in plants grown in calcareous soils. In waterlogged soils, however, Fe availability increases and can reach toxic concentrations. Rice is an important staple crop worldwide and faces iron deficiency or excess, depending on the growth conditions. To contribute to the study of mechanisms involved in response to Fe deficiency and resistance to Fe excess, experiments were carried out with rice cultivars BR-IRGA 409 (I409, susceptible to Fe toxicity) and EPAGRI 108 (E108, resistant to Fe toxicity) grown in culture solutions and submitted to Fe excess, control concentration or deficiency (500, 6.5 or zero mg L-1 Fe, respectively). Analysis of shoot dry weight confirmed the resistance of E108 plants to Fe excess. Mössbauer spectroscopy analysis indicated the presence of four different Fe3+compounds. The parameters obtained match those expected for ferrihydrite, lepidocrocite (and/or citrate) and Fe-nicotianamine. Mineral concentrations were determined using the PIXE (Particle Induced X-Ray Emission) technique. E108 plants had lower Fe concentrations than I409 plants when exposed to excess Fe. Except for lower Mn levels in roots and shoots, the excess of Fe did not result in lower nutrient concentrations in the susceptible cultivar compared to the resistant one. I409 plants seem to be affected directly by Fe toxicity rather than by secondary effects on mineral nutrition, whereas E108 plants seem to make use of the avoidance mechanism in the resistance to Fe overload. Both cultivars responded to Fe deficiency with allocation of P from roots to shoots. In addition to being more resistant to iron overload, E108 plants seem to be more efficient in inducing Fe deficiency responses.

The elements detected in this sample were Mg , Al , Si , P , S , Cl , K , Ca , Cr , Mn , Fe , Cu , Zn , Br , Rb , and Sr . Among them, spatial differences in the distribution of nine elements were observed between the vascular and mesophyll tissue. Si , Cl , K , and Ca were mostly accumulated in vascular tissue, while Mg , P , S , Cr , and Mn were for the most part accumulated in the mesophyll. The distribution of Ca appeared to follow cell wall contours. The distribution of some of these elements is compared to the function of the elements in living tissue and future possibilities for this type of investigation are discussed.

Abstract:

The cultivation of crayfish in the structure of aquaculture in the Middle Volga region can be an important component. Currently, natural crayfish populations in the Republic of Tatarstan include 2 species – narrow-toed crayfish (Pontastacus leptodactylus Esch.) and wide-toed crayfish (A. astacus L.). The development of aquabiological technologies allows the use of natural crayfish populations for the tasks of creating industrial breeding farms. In connection with the global trend of the growing popularity of crayfish in food use, the importance of research on the chemical composition of crayfish as objects of consumption grows. The chemical analysis of narrow-fingered crayfish revealed 13 elements, of which calcium is found in maximum amount in the dry residue. The calcium content in the narrow crayfish was 154.057 g/kg dry weight (fig. 1), the chitinous shell of crayfish contains relatively more calcium – up to 376.282 g/kg of dry weight. The following sequences of the content of chemical elements in crayfish from the Kuibyshev reservoir are noted:  in the muscle tissue of edible parts Ca ˃K ˃S ˃P ˃Cu ˃Fe ˃Zn ˃Mn ~ Br ˃Sr;  in the shell Ca ˃Si ˃P ˃S ˃K ˃Sr ˃Ti ˃Fe ˃Mn ˃Cu ˃Br ˃Zn ˃As. In crayfish from the Kuibyshev reservoir we studied, the raw muscle mass of the edible parts of the crayfish contained 88.80% of water, 10.28% of organic substances and 0.92% of mineral substances, and in the chitin-containing raw shells of crayfish, respectively, contained 59.2% of water, 36.42% organic matter and 4.38% mineral matter. The particular interest is the study of crayfish shells, since they consist mainly of chitin. It is a bearing polysaccharide for invertebrate, reaching 85% of the weight of the integuments. In the cuticle of arthropods, chitin forms composite complexes with proteins, pigments, calcium salts. In the composition of the shells of crayfish, 376.282 mg/kg dry mass of calcium is noted. In smaller quantities phosphorus, potassium, iron and zinc are noted. Titanium was found in crayfish shells in the amount of 1845 mg/kg dry weight and was not found in their muscle tissue and other aquatic organisms in the region. In the studied crayfish, the content of heavy metals in the wet mass was: Zn – 0.42 mg/kg; Cu 6.5 mg/kg; Fe – 1.39 mg/kg; Sr – 0.23 mg/kg. Residual amounts of zinc and copper in the muscular tissue of the edible parts of crayfish of the Kuibyshev reservoir are within the normal range. The content of hazardous elements (lead, arsenic, cadmium and mercury) in the crayfish from the Kuibyshev reservoir is within the sanitary and epidemiological norms, and in the Volga delta crayfish the lead content is exceeded.

Abstract:

Size exclusion chromatography (SEC), which separates molecules based on molecular volume, can be coupled with online inductively coupled plasma mass spectrometry (ICP-MS) to explore size-dependent metal–natural organic matter (NOM) complexation. To make effective use of this analytical dual detector system, the operator should be mindful of quality control measures. Al, Cr, Fe, Se, and Sn all exhibited columnless attenuation, which indicated unintended interactions with system components. Based on signal-to-noise ratio and peak reproducibility between duplicate analyses of environmental samples, consistent peak time and height were observed for Mg, Cl, Mn, Cu, Br, and Pb. Al, V, Fe, Co, Ni, Zn, Se, Cd, Sn, and Sb were less consistent overall, but produced consistent measurements in select samples. Ultrafiltering and centrifuging produced similar peak distributions, but glass fiber filtration produced more high molecular weight (MW) peaks. Storage in glass also produced more high MW peaks than did plastic bottles.

Abstract:

This study was conducted to investigate the effects of root inoculations with Bacillus cereus (N2-fixing), Brevibacillus reuszeri (P-solubilizing), and Rhizobium rubi (both N2-fixing and P-solubilizing) on plant growth, nutrient uptake, and yield of broccoli in comparison with manure (control) and mineral fertilizer application under field conditions in 2009 and 2010. Bacterial inoculations with manure compared with control significantly increased yield, plant weight, head diameter, chlorophyll content, nitrogen (N), potassium (K), calcium (Ca), sulfur (S), phosphorus (P), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu) content of broccoli. The lowest yield per plant, plant weight, steam diameter, and chlorophyll content were recorded in the control, but the manure with Bacillus cereus (BC), Rhizobium rubi (RR), and Brevibacillus reuszeri (BR) inoculations increased yield 17.0%, 20.2%, and 24.3% and chlorophyll content by 14.7%, 14.0%, and 13.7% over control, respectively. Bacterial inoculations with manure significantly increased uptake of macronutrients and micronutrients by broccoli. In conclusion, seedling inoculation with BR and especially RR may partially substitute costly synthetic fertilizers in broccoli.

Abstract:

ABSTRACT Early season onion crops, despite lower yield, is an opportunity for farmers to explore market and better prices in southern Brazil. Knowing the amount absorbed and the distribution of nutrients in the plant is essential for adequate management of fertilization. However, little information on this matter is available for onion, especially for organic farming and nontraditional periods in southern Brazil. The objective of this study was to evaluate the nutrient absorption and partitioning in open-pollinated onion cultivars grown in organic system. The experiment was conducted in the Canguiri-UFPR experimental organic farm, Curitiba-PR, with sowing in January. The experiment was arranged in a completely randomized design with three replications. Cultivars Franciscana IPA-10 (purple), Vale Ouro IPA-11 and Brisa IPA-12 (from Empresa Pernambucana de Pesquisa Agropecuária - IPA), Alfa Tropical (from Embrapa Hortaliças), Alfa São Francisco (VIII cycle) and Alfa São Francisco-RT (thrips resistant- genotype under test; from Embrapa Semi-árido), and BR-29 (Topseed-Agristar) were selected for the study. Chemical analyses were performed for shoot and bulbs collected at harvest. The production potential of cultivars varied, and the most productive ones were the most efficient in converting the nutrients absorbed in bulb yield. The order of nutrient contents in the shoots was K > N > P > Ca > Mg > Fe > Zn > Mn = B > Cu, whereas in the bulbs it was K > N > P > Ca > Mg > Fe > B > Zn > Cu > Mn. Nutrients were required in the following order of amount K > N > P > Ca > Mg > Fe > Zn > B > Mn > Cu, per ton of fresh bulbs, and accumulated in greater quantity in the shoot, except Zn, which had higher concentration in the bulb.

Abstract:

Thyroid adenomas (TA) are benign tumors, but there is a 20% possibility of malignant transformation. The distinguishing between the TA and thyroid cancer (TC) is tricky, therefore new TA biomarkers are needed. Furthermore, the role of chemical elements (ChE) in etiology and pathogenesis of TA is unclear. The aim of this exploratory study was to evaluate whether significant changes in the thyroid tissue levels of twenty chemical elements (ChE) Al, B, Ba, Br, Ca, Cl, Cu, Fe, I, K, Li, Mg, Mn, Na, P, S, Si, Sr, V, and Zn exist in the adenomatous transformed thyroid. Thyroid tissue levels of twenty ChE were prospectively evaluated in 19 patients with TA and 105 healthy inhabitants. Measurements were performed using a combination of non-destructive and destructive methods: instrumental neutron activation analysis and inductively coupled plasma atomic emission spectrometry, respectively. Tissue samples were divided into two portions. One was used for morphological study while the other was intended for ChE analysis. It was found that contents of of Al, B, Br, Cl, Cu, Na, and Zn are significantly higher whereas the levels of I some lower. in TA than in normal tissues. It was supposed that the changes in levels Al, B, Br, Cl, Cu, I, Na, and Zn in thyroid tissue can be used as TA markers.

Abstract:

The problems of production of copper-nicckel alloys ingots by semicontinuous casting method are analysed. The requirement of grain size refinement in cast alloys macrostructure is shown. It is necessary to reduce the probability of hot cracks formation and increase the fabricability of cast bars during plastic working. The reasonability of fine fraction of Ni-Mg-Ce master alloy application for inoculation of copper-nickel alloys is established. The results of laboratory experiments on the study of master alloy quantity influence the structure and hardness of Cu-5Ni-1Fe, Cu-10Ni-1Fe-1Mn and Cu-30Ni-1Fe-1Mn copper-nickel alloys are presented. On the basis of industrial experiments it is revealed that inoculation of Cu-5Ni-Fe alloy ingots of diameter 200 mm by Ni-Mg-Ce master alloy leads to considerable reducing of macrograin size. It allows to improve mechanical properties of ingots and ensure their uniform distribution in cross section of ingots. It is established that residual magnesium content in alloy must be in range from 0,02 to 0,06 wt. %. The use of Ni-Mg-Ce master alloy makes it possible to increase the processability of copper-nickel alloys during plastic working and utilize the fine fraction master alloy scrap inevitably formed during its production.

Abstract For the first time active moss biomonitoring was used to assess trace element deposition in the capital of the Republic of Moldova, Chisinau. Moss Sphagnum girgensohnii samples were exposed in bags at three sites of Chisinau from October, 2016 to March, 2017. The content of 30 elements: Na, Mg, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, As, Br, Rb, Mo, Sr, Sb, Ba, La, Ce, Cs, Hf, Th, Cu, Cd, Pb, and U in the exposed and unexposed mosses was determined by neutron activation analysis and atomic absorption spectrometry. According to the relative accumulation factor, the most abundant elements in the samples were V, Cr, Fe, Ba, La, As, Sb, U, and Pb. Such elements as Cl, K, and Rb were depleted from the moss tissue during the time of exposure. Principal component analysis was used to identify and characterize different pollution sources. The obtained results indicate that the use of S. girgensohnii moss bags is a simple and inexpensive technique to monitor major and trace element content in the air of urban area.

This study investigates the elemental composition of Cement, Granite, Ceramic tiles and Plaster of Paris (POP) which are extensively used as building material in Zaria, Kaduna State. X-ray fluorescence (XRF) technique was employed in this work to determine the elemental composition of the building materials. The samples were crushed to a fine powder, sieved through a 250 mm mesh and dried in an oven at 1100 C to ensure the complete removal of moisture. The results showed the presence of (Mg, Al, Si, Ca, Fe, Sn, Cl, Ti, S, P, Mn, Co, Zn, Mo, Pb, Cr,V, Cu, Br, Cd, Ba, Hg, and Ni) in various concentrations. Mg, Al, Si, Ca, Fe, Sn, Cl, Ti and S were available in relatively high concentration in all the samples with P, Mn, Co, Zn, Mo and Pb, found in relatively lower concentrations in some of the samples while Cr and Ni were only present in Ceramic tile samples; which was attributed to coloring agents used in the tile making process. This shows that the elemental composition is in agreement with the composition of the earth crust which is the source of the building materials. The analysis is of importance and useful to the construction industry as well as dwellers of the Zaria built environment. Keyword: Composition, Plaster of Paris, Cement, Granite, Ceramic Tile

Bk. and Br. isolate 238B were grown in a split-plot factorial design with pH as main plots and Al concentration and ectomycorrhizal fungal species as subplots. No Al, 50 mg Al/g substrate, and 100 mg Al/g substrate were added to the potting soil mixture, which was adjusted to a final pH of 3, 4, or 5. The seedlings were watered with one-fifth strength Arnon's solution having a pH of 3, 4, or 5 and containing 100, 50, or 0 mg Al/L. The experiment was conducted to determine the effect of acidity and concentration of Al on ectomycorrhizal formation. As solution acidity and concentrations of Al increased, ectomycorrhizal formation, root weight, shoot weight, total weight, root:shoot ratio, and B concentration decreased; however, concentrations of Fe, Mn, P, and Zn in the seedlings increased. N, Ca, K, and Mg concentrations did not vary significantly in any of the treatments. Results of this study suggest that pH and Al have a complex effect on ectomycorrhizal formation and nutrient uptake in A. balsamea seedlings.

Abstract:

Pearl millet (Pennisetum glaucum(L.) R. Br.) is an important staple cereal cultivated in the arid and semi-arid tropics of Asia and Africa, regions severely affected by malnutrition. Knowledge about the extent of genetic variability and patterns of agro-morphological variation in local germplasm from a target region is an important prerequisite for efficient crop improvement. To assess the potential of Sudanese pearl millet landraces as sources of desirable traits for pearl millet improvement including biofortification, a total of 225 accessions were evaluated in Sudan at three locations for agro-morphological traits and at one location for grain mineral nutrient contents (Fe, Zn, Ca, P, K, Mg, Mn, S, Na, Cu and β-carotene). Genetic variation was highly significant, but relatively limited for some agro-morphological traits (62–78 d to flowering, 119–188 cm plant height and 16–34 cm panicle length), pointing to the potential usefulness of a targeted diversification for these traits. Self-pollinated grain micronutrient contents showed a wide variation: 19.7–86.4 mg/kg for Fe and 13.5–82.4 mg/kg for Zn. Significant and positive correlations among most of the nutritional traits were observed; therefore, enhancement of the concentrations of some nutrients will lead to the improvement of other related nutrients. No significant associations were observed between the nutritional and agro-morphological traits, indicating good prospects for simultaneous improvement of both trait categories. No clear patterns of geographic differentiation for specific traits were detected for the Sudanese pearl millet. Nutrient-rich accessions were identified and those with acceptable agro-morphological traits are encouraging materials for future pearl millet biofortification programmes in Sudan.

Abstract:

Pepaya sangat potensial dibudidayakan di lahan rawa pasang surut, tetapi ketersediaan hara dalam tanahnya tergolong rendah. Nitrogen dan kalium merupakan hara yang relatif banyak dibutuhkan pepaya, sehingga budidaya pepaya di lahan rawa pasang surut perlu penambahan hara tersebut melalui pemupukan. Penelitian dilakukan di lahan rawa pasang surut eks proyek lahan gambut (PLG) sejuta hektar di Kecamatan Mantangai, Kabupaten Kapuas, Provinsi Kalimantan Tengah dari bulan Juni 2007 sampai April 2008. Tujuan penelitian ialah untuk mengetahui pengaruh pemberian hara N dan K terhadap pertumbuhan dan produksi pepaya. Benih pepaya yang digunakan ialah varietas Merah Delima. Penelitian disusun dengan rancangan acak kelompok faktorial dengan tiga ulangan. Faktor I ialah takaran pupuk nitrogen yaitu 0, 125, 250, 375 g/tanaman dan faktor II ialah takaran pupuk kalium (K20) yaitu 0, 150, 300, 450 g/tanaman. Tiap unit perlakuan terdiri atas 10 tanaman. Parameter yang diamati meliputi sifat kimia tanah, pertumbuhan vegetatif, dan produksi tanaman. Hasil penelitian menunjukan bahwa ketersediaan N, P, dan Fe di lokasi penelitian tergolong sangat tinggi, K rendah, sedangkan Ca dan Mg sangat rendah. Pemupukan N hingga taraf 375 g/tanaman tidak berpengaruh nyata terhadap peningkatan pertumbuhan vegetatif tanaman pepaya. Namun pada fase produktif (10 bulan setelah tanam), panjang buah secara nyata meningkat dengan pemberian N 250 g/tanaman. Pemberian K2O pada taraf 300g/tanaman secara nyata meningkatkan pertumbuhan vegetatif dan produksi tanaman (jumlah, bobot, panjang, dan PTT), sedangkan pemberian K2O yang melebihi 300 g/tanaman mengakibatkan penurunan pertumbuhan, produksi, dan kualitas buah. Hasil penelitian ini dapat digunakan sebagai landasan penelitian dan penyusunan rekomendasi pemupukan pepaya di lahan rawa pasang surut. Papaya has opportunity to be cultivated in tidal swamp land but the availability of its nutrient in the soil is low. Nitrogen and potassium are the major nutrients needed by papaya, so that the nutrient should be added through fertilization. The research was conducted in tidal swamp land in Mantangai, Kapuas, Central Kalimantan Province, from June 2007 to April 2008. The objective of this research was to investigate the effect of nutrient N and K on growth and production of papaya in tidal swamp land. Merah Delima variety was used as a seed in this research. The factorial experiment was arranged in a randomized block design with three replications.The first factor was dosage of nitrogen of 0, 125, 250, and 375 g/plant and the second factor was amount of potassium (K2O) from 0, 150, 300, and 450 g/plant. Each unit of treatment consisted of 10 plants. The parameters observed include the chemical properties of soil, vegetative growth, and crop production. The results showed that the availability of N, P, and Fe at the research location was classified as very high, whereas K was low, Ca and Mg were very low. Nitrogen fertilization up to level 375 g/plant did not significantly increase the vegetative growth of papaya plants because of its high availability of the nutrition on the soil. However, in the productive phase (10 months after planting), fruit length was significantly increased with application of N in dose 250 g/plant. Application of K2O fertilizer on 300/plant increased significantly vegetative growth and yield (number of fruit, fruit weight, fruit length, and TSS), whereas application of more than 300 g/plant decreased their growth, yield, and fruit quality. The results can be used as the basis to arrange and formulate fertilizer recommendation on papaya which is mainly grown on tidal swamp land.

Schimp.) and lichen (Cladonia fimbriata (L.) Fr.) collected in three locations in Eastern Serbia over years 2006-2010. Concentrations of six elements (Zr, Nd, Gd, Tm, Yb, and Lu) in mosses in Serbia are measured for the first time. For other elements, the obtained concentrations fall within the ranges reported for mosses and lichens in Europe, but no declining trend in concentrations of V, Cd, Cr, Zn, Ni, Fe, and Cu, that has been described in the literature, can be inferred from our results. Factor analysis shows that terrigenous and industrial components are the highest contributing factors to the elemental composition and that the most polluted measurement site is in the vicinity of a copper mining and smelting complex.

Abstract:

THE DEBRIS PARTICLES ANALYSIS OF RSG-GAS COOLANT TO ANTICIPATE SEDIMENT-INDUCED CORROSION. The reliability of the structures, systems and components (SSC) of the G.A. Siwabessy Multipurpose Research Reactor (RSG-GAS) should be maintained to keep the reactor operates safely. Chemical control and management of coolant is one factor which determines the SSC’s reliability. The debris sedimentation in the primary coolant system must be examined. Debris occurs in the reactor pool, originating from airborne dust from the engineering hall. Several elements contained by the sediment can induce corrosion. This research was conducted to identify the trace elements which were contained in the sediments and determine their concentrations. The objective was to anticipate the occurrence of galvanic and pitting corrosion due to the presence of elements which are more noble than aluminum. The measurement methodology is Neutron Activation Analysis (NAA). Two groups of samples were analyzed; the first group was sampled from the debris trapped in the mechanical filter after the resin column, or known as the resin trap, and second was sampled from the debris which adhered to the heat exchanger tube. The primary coolant debris analysis showed that the neutron-activated sediment contained Na-24, Na-25, Al-28, Mg-27, Cr-51, Mn-54, Mn-56, Co-58, Co-60, Ni-65, and Fe-59. The Mn, Cr, Co, Ni, and Fe are more noble than aluminum can induce galvanic corrosion while Na, Ba, Al, and Mg are not. The radionuclides contained by the result of neutron activation of sediment from the heat exchanger tube are Mn-56, Na-24, As-76, Br-82, Fe-59, Zn-65, Cr-51, La-140, and Sc-46 which are mostly carbon steel corrosion products. Those elements do not initiate galvanic corrosion. The prevention of galvanic corrosion can be done by periodic maintenance.Key Words : sediment, debris, corrosion, galvanic, pitting, RSG Gas

1. During a period of 2·5 years, every 3 months 221 different food items forming a ‘market basket’ were purchased, prepared and divided into twenty-three food-commodity groups. The ‘market basket’ was based on a study of the dietary intake of 18-year-old male, Dutch adolescents. In the (homogenized) food groups various minerals and trace elements were determined.2. The mean daily amounts of cadmium (21 μg), mercury (0·7 μg), lead (32 μg), tin (0·65 mg), arsenic (38 μg) and bromine (8 mg) in the diet of adolescents, as calculated from the concentrations analysed in the food groups, were all (well) below the Food and Agriculture Organization/World Health Organization acceptable daily intake (ADI) value (Codex Alimentarius Commission, 1984).3. The mean daily amounts of zinc (14 mg) and selenium (72 μg) seemed to be adequate compared with the Dutch recommendations, (Voedingsraad (Dutch Nutrition Council) 1986). The amounts of copper (mean value 1·5 mg/d) and iron (mean value 14 mg/d) in the total diet were marginal. Contents of calcium (1340 mg/d), magnesium (433 mg/d) and iodine (402 μg/d) were all well above the Dutch recommendations for male adolescents. Sodium intake, corresponding to 11 g sodium chloride/d, was higher than advised.4. It is concluded that the amounts of As, Br and toxic heavy metals in Dutch total-diet samples of male adolescents are of little concern as regards health aspects. Among the essential trace elements, Fe and Cu contents seem to be marginal. Some concern regarding the salt content is indicated.

Abstract:

In the present study, the effects of copper oxide nanoparticles (CuO NPs) on bioactive compounds, the ultrastructural modifications which can occur, and elemental content of wheat were investigated. Changes in the wheat plants grown in presence or absence of CuO NPs were estimated. The application of CuO NPs decreased the amounts of chlorophylls and carotenoids and increased the amounts of polyphenols and antioxidant capacity. Ultrastructural analysis showed that the plants treated with CuO NPs were negatively affected. Soil amending completely inhibited the accumulation of seventeen elements, while K, Br, Al, and Zn were accumulated and Cl, Na, Ba, and Sr content decreased in wheat samples, regardless of the type of NPs applied. The application of chemically obtained NPs induced the most significant changes, completely blocking the assimilation of Fe, Mo, As, Sb, and Sm, and favoring much higher accumulation of Br than biogenic NPs. The decrease in chlorophylls and carotenoids is correlated with increase in antioxidant capacity, and occurs with increase of Mo, Al, Mg, K, Zn, and Ca content. The behavior of total polyphenols is correlated with Br content, and antagonist to Al behavior. From the point of view of bioactive compounds, the most affected plants were those that grew in the presence of CuO-NP-cel, while from the point of view of elementary analysis, the most affected plants were those grown in the presence of CuO-NP. By corroborating the obtained results, it was found that the CuO NPs have a negative effect on wheat plants.

Abstract:

Within the increase of Coffee production and its export as well, a larger resourcefulness is been required to manufacture its bags. Due to these increases, a natural fiber source became valued again despite its growing had been forgotten for some years. The mallow is being observed as an excellent ecological alternative, but the knowledge of its handling and natural requirements are restricted, by the fact of lately inattention in this natural fiber. In this context with the purpose of contributing with the knowledge of this cultivation, an experiment was settled aiming to evaluate its growth, to characterize the visual of macro and micronutrients deficiency symptoms to determine the analytical levels of these nutrients. The mallow plants, variety BR-01, were cultivated in the Department of Soil’s greenhouse from Universidade Federal Rural da Amazônia-UFRA, in plastic vases containing 3 kg of ground silica and submitted to the following treatments: complete, omission of N, omission of P, omission of K, omission of Ca, omission of Mg, omission of S, omission of B, omission of Cu, omission of Fe, omission of Mn and omission of Zn. After a period comprehended between 7 and 29 days, the occurrence of deficiency symptoms has started, except for the treatments with omission of S, Cu and Zn. The plants development were mostly affected by the treatments with omission of B and Ca.
