Abstract Three layered double hydroxides (LDH) [Mg1−xAlx(OH)2]x+(Am−)x/m]·nH2O and [MII 1−xMIII x (OH)2]x+(Am−)x/m]·nH2O (MII — Mg, Co, Ni; MIII Al; A CO3 2−) were successfully synthesized by the low supersaturation method. The as-synthesized LDH samples thermally decomposed derived mixed metal oxides reformed back to structures in water magnesium nitrate media at different temperatures. All characterized X-ray diffraction (XRD) analysis, thermogravimetric (TG) fluorescence (XRF) analysis...
Both real total and aqua regia contents of trace elements in soils are often denominated by the same word “total” though results not identical. The formulas would be helpful for recalculation to totals . Data primary were taken from International Soil‐Analytical Exchange Program Wageningen Evaluating Programs Analytical Laboratories. degree extractability DE element a sample was calculated weighting ratios median different periods with weights proportional respective number determinations....
Abstract The relationship between real total contents of the major elements Na, Mg, Al, Si, P, S, K, Ca, Ti, Fe and trace Ag, As, B, Ba, Co, Cr, Cu, Mn, Mo, Ni, Pb, Sb, Se, Sn, V, U, Zn in topsoil from central part Vilnius is analysed. amounts most were determined by energy-dispersive X-ray fluorescence, while Co measured optical atomic emission spectrophotometry. Two factors distinguished according to elements: anthropogenic (A) including Fe, S clayey (C) Ti. Boron, Cr U are significantly...
The aim of investigation was to find out the distribution and relationships between urban landscape sensitivity chemical pollution (S) topsoil additive contamination Zd in urbanized nucleus Vilnius taking into account different functional zones. calculated according concentration coefficients 13 elements, scores S were based on integrated evaluation 7 criteria. Comparison indices sampling sites. As indicates degree influence load elements‐pollutants an environment, it can only modify, but...
Intraspecific chemical polymorphism is characteristic of essential oil bearing Thymus pulegioides (Lamiaceae). Soil composition and climatic conditions can influence not only quantitative qualitative oils, but also on prevalence different chemotypes in space. The purpose study was to determine the impact edaphic factors T. potential prevalence. It were investigated 131 habitats all ten sub-districts Lithuania. Essential oils isolated by hydrodistillation analysed GC-FID GC-MS. content humus...
Abstract Lichen community changes were investigated on trees within a colony of great cormorants ( Phalacrocorax carbo sinensis ) established in pine forest the Curonian Spit, western Lithuania. The impact birds has altered number and characteristics substrata available to lichens. lowest lichen species occurrences was registered most active part with highest nest density. patterns strongly related P Ca content pH values. Some acidophytic showed negative correlations, both long-term...
Two sections (Daumantai-1 and Daumantai-3) in East Lithuania expose Early-Middle Pleistocene lacustrine-alluvial, deposits which lie on a thin Neogene layer older Devonian rocks. They are overlain by glacigenic deposits. Geochemical, palaeomagnetic, magnetic susceptibility, plant macrofossil, diatom investigations were performed to determine the changes sedimentary environment. Cluster analysis of geochemical variables (10 major elements, 16 trace total organic inorganic carbon) revealed...
Thermoluminescence dating of potsherds found in the Skomantai hill-fort and settlement areas western Lithuania confirms that they were fired from 4th to 10th century historical human activity existed at Skomantai. The aim this research was investigate relationship chemical elements with total organic carbon inorganic distinguish possible anthropogenic indicators study area which is characterised by sandy sediments wooden construction. Twenty-six determined EDXRF. Two groups distinguished:...
