Sediment, suspended matter, river water and ground water samples were collected at twelve sites in the drainage valley of the Nile River, around Sohag (Central Egypt) and close to the Aswan High Dam. Elemental composition of the river water (27 elements), ground water (eight elements), suspended matter (12 elements) and sediments (12 elements) was studied. Aswan High Dam construction, agricultu...

V. F. Laurie, E. Villagra, J. Tapia, J. E. S. Sarkis, and Marcos A. Hortellani. 2010. Analysis of major metallic elements in Chilean wines by atomic absorption spectroscopy. Cien. Inv. Agr. 37(2): 77-85. A set of 75 wine samples from seven of the major wine producing regions in Chile were analyzed with flame atomic absorption spectroscopy (AAS) to determine their content of major metallic eleme...

Dietary fibers, major phenolics, main minerals, and trace elements in persimmons and apples were analyzed and compared in order to choose a preferable fruit for an antiatherosclerotic diet. Fluorometry and atomic absorption spectrometry following microwave digestion were optimized for the determination of major phenolics and minerals. Total, soluble, and insoluble dietary fibers, total phenols,...

background: the present study investigated the effect of the middle east dust storm episodes on the concentration and composition of pm 10 during april to september 2013 in sanandaj city, western iran. methods: sampling was once every six days, and on dusty days using an omni air sampler. the pm 10 sample was collected on polytetrafluoroethylene filters. average of 24 h values of pm 10 mass con...

introduction: soil has an important role in nutrient cycle and an important function in storage, refinement, and movement of nutrients for the living and non-living parts. soil pollution of heavy metals and elements is one of the common pollution impacts of human activities, especially industry. realization of distribution pattern of these elements and their anthropogenic sources is a major par...

The presence and bioavailability of potentially toxic elements in the soil–plant system are major limitations to application compost agricultural soils. In this study, content changes nutrients four organic wastes, namely household waste, sewage sludge, chicken manure, cow/sheep were analyzed during composting, quality products was assessed view their impact on environment. objective study dete...

The transition from the Semail ophiolite mantle to underlying metamorphic sole was drilled at ICDP OmanDP Hole BT1B. We analyzed bulk major, volatile and trace element compositions of mantle-derived listvenite series rocks, with aim constrain chemical transfers associated peridotite carbonation along basal thrust. comprise variously carbonated serpentinites (fuchsite-bearing) listvenites. They ...

1. introduction dust storm is a natural phenomenon that occurs frequently in the arid and semi-arid regions all over the world (alijani, 1997). dust can affect soil fertility, forests, rivers, lakes, and marine ecosystems around the world (mctainsh et al., 2007). therefore, soil erosion can lead to the loss of the minerals and organic matter of topsoil. some elements of dust have also an indire...

Energies, transition probabilities, and lifetimes are calculated for 3d states in Ca-like ions with nuclear charges Z ranging from 22 to 100. Relativistic many-body perturbation theory ~MBPT!, including the Breit interaction, is used to evaluate retarded M1 and E2 matrix elements. The calculations start from a 1s2s2p3s3p Dirac-Fock potential. First-order perturbation theory is used to obtain in...
