This paper presents the study of the chemical composition of Petrovskaya variety of turnip after the non-root treatment of vegetating plants with the solution of trivalent chromium. The treatment has been performed with the solutions of chromic potassium sulphate with chromium concentrations of 0.002% and 0.005%. The experiment has been conducted according to the following scheme: 1. NPK (background) – control version; 2. NPK + HO Cr 0.002%; 3. NPK + HO Cr 0.005%. Nitroammophoska was used as the background macro fertiliser during the sowing at the rate of 30 g/m2. In the control versions plants have been treated with the distilled water. The content of chromium in root vegetables has been assessed using the method of atomic absorption spectroscopy. It is shown that after the treatment with the solution of chromic potassium sulphate the average content of chromium in root vegetables increased by 31.3% in NPK + Cr 0.002% version and by 55.6% in NPK + Cr 0.005% version in comparison with the control version. At the chromium concentration of 0.002% the content of dry matter in turnip remained at the level of control version, the content of dry soluble matters and ascorbic acid decreased down to 5.9% and 28.60 mg/100 g, the level of nitrates in root vegetables increased up to 286.0 mg/kg of wet mass. At the chromium concentration of 0.005% the content of dry matter in turnip decreased down to 10.4%, the content of dry soluble matters increased up to 7.3%, the content of ascorbic acid and nitrates decreased down to 27.81 mg/100 g and 210.2 mg/kg of wet mass, respectively.

Root Treatment

The paper presents data on the study of the chemical composition of Petrovskaya turnip variety when using non-root treatment of vegetating plants with a selenium-containing solution. Treatment of plants was carried out with a solution of sodium selenite with a concentration of 0.0005 and 0.001% by Se. The experiment was carried out according to the following scheme: 1) NPK (background) – control variant; 2) NPK + NRT Se 0.0005%; 3) NPK + NRT Se 0.001%. As a background macro fertiliser, nitroammophosca was added to the soil at the rate of 30 g/m2. In the background options the treatment of plants was carried out with distilled water. The content of selenium in turnip roots was determined by atomic absorption spectroscopy. It is shown that when treated with a solution of sodium selenite, the selenium content in the product part of plants in the variant of NPK + Se 0.0005% increased by 1.5 times, and in the variant of NPK + Se 0.001% – by 1.8 times compared to the control variant. It was found that non-root treatment of vegetating plants with selenium-containing solution led to a decrease in the content of dry matter in turnip roots by 1.5-1.6%, and the content of dry soluble substances remained at the level of the control variant. At the concentration of selenium in the 0.0005% solution, the content of ascorbic acid in root crops decreased by 7%, and the content of nitrates increased by 10.1% relative to the control variant. An increase in the concentration of selenium in the 0.001% solution led to a decrease in the content of ascorbic acid in root crops by 15.9% and an increase in the content of nitrates in them by 20.6% compared to the control variant.

The bulk mineralogy and uptake ability of four samples (SA1 to SA4) of clinoptilolite-bearing tuffs from Samos Island, Greece were investigated. The semi-quantitative mineralogical analyses of the samples were determined by powder-XRD (PXRD). The chemical composition of the samples analysed by Atomic Absorption Spectroscopy (AAS), reflected the bulk mineralogy of the samples. The semi-quantitative mineralogy of the samples was found to be in good agreement with their chemical compositions. The uptake ability was measured using the ammonium saturation method (AMAS). The samples consist of clinoptilolite (47-74 wt. %), micas (muscovite and/or illite) (4-13 wt. %) and smectite (2-13 wt. %) and have uptake abilities between 133 and 184 meq/100g. Such materials, especially the clinoptilolite-rich ones, could be used in a wide range and scale of agricultural, aquacultural, industrial and environmental applications.

Abstract In several series of 581 samples, Higher Fungi, especially from the Boletales and Gasteromy­cetes, were analyzed by atomic absorption spectroscopy on their content of the trace metal silver. The highest Ag-content was found in the Lycoperdales (max. 50 mg/kg dry matter) and in some species of the genus Boletus (max. 15 mg Ag/kg). The other fungi tested showed a mean silver content of 1 mg/kg or lower. The species with the highest amounts of the trace metal were found to enrich silver 300 fold compared to the substrate.

Experimental Parameters

In this paper, a manual-controlled injection nanometer calcium titanate based on glass fiber filter enricher (MICTE) was prepared, and its application in speciation of Cr (III) and Cr (VI) was studied. The optimum experimental parameters for separation of the Cr (III) and Cr (VI) have been investigated. The results showed that the MICTE had adsorption capacity towards the Cr (III) and Cr (VI). And two forms of chromium show different adsorption capacities at different pH values, Cr (III) could be adsorbed at pH 9, but Cr (VI) cant be adsorbed. Whereas Cr (VI) retained at pH 3, but Cr (III) cant be adsorbed. Therefore, it is possible that the two forms of chromium are complete separated. The Cr (III) and Cr (VI) could be completely eluted with 1 mol·L1 HCl and 1 mol·L1NaOH, respectively. The chromium concentration was measured by atomic absorption spectroscopy. A new method for determination of the speciation of chromium in environmental water samples based on the manual-controlled injection enricher and atomic absorption spectroscopy determination was proposed. The method was successfully applied for the determination of Cr (III) and Cr (VI) in environmental waters with satisfactory results.

Colorimetric Methods

Abstract Colorimetry of iron in serum with Ferrozine (as used in the Technicon SMAC) or with bathophenanthroline (as used in the Du Pont aca) is influenced by EDTA, in contrast to such measurements with atomic absorption spectroscopy. Therefore EDTA contamination should be avoided with these colorimetric methods. If, however, contamination with EDTA is suspected, addition of zinc sulfate to serum or to the SMAC "ascorbic acid reagent" will cancel the influence of EDTA on measurements of iron in the SMAC.

The presence of some chemical compounds at higher levels than maximum permissible concentrations (MPC) in the drinking water, suggests of water resources pollution. In this paper the following elements were analyzed: total arsenic, cadmium, lead, cooper and zinc. Twelve samples of water from the water supply system from the city of Skopje were examined during one year from three different springs. Also, ten samples of bottled water from three producers from the Macedonian market were tested.The determined average mass concentrations of total As, Cd(II), Pb(II), Cu(II) and Zn(II) in the analyzed water samples from the water supply system are 1.35 μg/l, 0.06 μg/l, 0.6 μg/l, 0.9 μg/l and 1,12 μg/l, respectively, and for the tested bottled water, the mean values ranges from 0.56 - 0.83 μg total As / l, 0.053 - 0.056 μg Cd(II)/l, 0.51 - 0.54 μg Pb(II)/l , 0.6 - 0.87 μg Cu(II)/l and 0.68 - 0.8 μg Zn(II)/l water.The following instrumental analytical methods and techniques were used for the analysis of the tested samples of drinking water: flame atomic absorption spectroscopy (AAS), atomic absorption spectroscopy with hydride cеll, electrothermal atomic absorption spectroscopy.The obtained results are shown in tables and graphic form. According to the obtained results a comparative analysis was carried out indicate that it is a water of good quality that can be used in different branches of the process industry.The obtained results in this paper do not exceed the values of the MPC of the Republic of Macedonia prescribed by the legal regulations for the drinking water, which confirm the health safety of the drinking water from the water supply system in the city of Skopje and the packed waters from the Macedonian market in relation to the tested elements.
