The samples of soils, drinking water and hair of habitants of 15 districts in Tashkent region studied using the method of neutron activation analysis. The results obtained from soil and drinking water analyses indicated that contents of Zn, Co, Cu and other elements in a number of districts are higher in comparison with average values throughout the region. This is related to developed industry in these regions. The analysis of the habitants' hair also indicated increased values, which are caused by environmental contamination and working conditions. For generalized assessment of environmental condition it was suggested to use the logarithm of multiplication of the lithophylic elements (Ba, Ca, K, La, Na, Rb, Sc, Sr) content, characterizing the geochemical condition. And similarly, the logarithm of multiplication of potential pollutants, typical for this area, such as Br, Co, Cr, Sb, U, Zn content in soil, water and hair was used as conditional index of overall pollution. It was demonstrated, that fluctuations of lithophylic elements content logarithm value throughout the districts of the region are insignificant and fall within range of 3941, while logarithm values for the potential pollutants vary from 3.1 to 9.3. The distribution of a hypothetical integral pollutant is presented in the cartogram. The correlation analysis conducted has established a relationship between the content of elements in environmental objects and some diseases, indicating that increased or decreased content of elements in the hair is highly likely one of the signs of a particular disease, especially in environmentally disadvantaged districts of the region.

A study was undertaken to evaluate the inorganic elements for humans in two Indian medicinal plants leaves, namely Sphaeranthus indicus, and Cassia fistula by Instrumental Neutron Activation Analysis (INAA). INAA experiment was performed by using 20 kW KAMINI Reactor at Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam. The emitted gamma rays were measured using gamma ray spectrometer. The concentrations of Al, Br, Ca, Fe, K, La, Mg, Mn, Na, Sc, V and Zn were determined in the selected medicinal plants. The medicinal leaves are using in treatment of various important ailments. The elemental content in selected medicinal leaves is various proportions depending on the soil composition, location of plant specimen and the climate in which the plant grows.

Abstract The synthesis of gold and silver nanoparticles by the blue-green algae Spirulina platensis for medical purposes was studied. A complex of optical and analytical methods was used in order to characterize produced nanoparticles. It was shown that the extracellular formation of metal nanoparticles of spherical shape with sizes in the range between 8 and 40 nm (the average size of 20-30 nm) takes place. The characteristics of gold and silver nanoparticles in the Spirulina biomass were compared. The role of biosorption processes in the synthesis of nanoparticles was estimated by using equilibrium dialysis. A positive influence of sonication on the process of microbial synthesis and yield of nanoparticles were demonstrated. The neutron activation analysis and the atomic absorption spectrometry were applied for characterizing the dynamics of gold and silver nanoparticles formation in the Spirulina platensis biomass. The neutron activation analysis was used for studying the elemental content of the Spirulina platensis biomass.

Analytical Technique

Most powerful primary analytical technique, neutron activation analysis, was applied to study indigenous bacteria, namely, Arthrobacter genera which can be successfully used in detoxification and immobilization of toxic substances. In the present study the effect of Cr(VI) on the elemental content of these bacteria has been examined. The concentrations from 12 to 19 elements such as Na, Al, Cl, K, Fe, Co, Zn, As, Br, Rb, Sr, Sb, Ba, Tb, Th, U were determined in the bacterial cells. The high rate of Cr accumulation in the tested bacterial cells was shown. In bacteria treated with chromate some similarity in the behaviour of the following essential elements − potassium, sodium, chlorine − was observed. Such non-essential elements as Ag, As, Br and U were determined in all bacteria and have to be considered by cells as toxins.

Abstract The botanical origin of seven types of Slovenian honey was investigated by analysis of their elemental content using k0-instrumental neutron activation analysis. A total of 28 representative samples were collected from beekeepers all over Slovenia in 2 consecutive years. Nineteen of the 37 elements measured were present in amounts above their LOD. The present study suggests that the determination of only alkali elements might be sufficient for the classification of Slovenian honeys according to their botanical origin. Linden and multifloral honeys can be differentiated on the basis of Na content. The differentiation of forest, spruce, and fir honeys is possible on the basis of differences in Cs, K, and Rb content. The difference between Na and Rb content can be used as a discriminating tool between light and dark honeys, because light honeys (black locust, linden, and multifloral) contained more Na than Rb, whereas it was the opposite for dark honeys (chestnut, forest, spruce, and fir). Statistically significant correlations were found between K and Rb and between K and Cs content. This study represents a considerable step in filling the knowledge gap concerning both the determination of elements present in low concentrations and the botanical origin of Slovenian honey.

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.
