This study, carried out in tailings from two sediment-hosted stratiform copper deposits the Lublin-Głogów Copper District Poland (Kupferschiefer-type deposit) and Zhezkazgan (cupriferous sandstone-type Kazakhstan, analysed mineralogy of copper, zinc, lead minerals as related to metal accumulation sediments. Microscopic study reflected light SEM–EDS (Scanning Electron Microscope—Energy Dispersiv...

Ambient air dust samples were collected from industrial, commercial and residential areas of four metropolitan cities (Delhi, Calcutta, Madras and Cochin) in India, and were analysed for 27 elements (As, Ba, Br, Ce, Co, Cr, Cs, Cu, Eu, Hf, Hg, Fe, Ga, La, Lu, Na, P, Sb, Sc, Se, Sr, Ta, Tb, Th, Rb, Yb and Zn) by Instrumental Neutron Activation Analysis (INAA). Samples were irradiated with therma...

A simple and sensitive method for the determination of some metalloids and heavy metals in water samples is presented. The method is based on the preconcentration of the attachment of chelating functionalities with metalloids and toxic metals irreversibly and targeted towards toxic metals adsorbed on modified activated carbon, activated carbon and red soil particles at pH 3.0–9.0±0.2, followed ...

Introduction: Mantle derived peridotite xenoliths ranging in modal composition between fertile lherzolites and modally metasomatized harzburgites has been analyzed by instrumental neutron activation analysis (INAA) for As, Sb and REE. In many melt depleted mantle samples (harzburgites) the incompatible element concentrations are much higher than those estimated for the fertile mantle. The reaso...

OBJECTIVE Relatively little is known about the trace elements content of human milk from different countries. This has not been fully investigated especially among Iranian women. This study aimed to assess the concentration of Rubidium (Rb) as a poisonous trace element in transitional breast milk of lactating mothers living in Mashhad. METHODS Forty nursing mothers in early lactation 3 days t...

Instrumental neutron activation analysis (INAA) and inductively coupled plasma mass spectrometry (ICP-MS) were used to analyse water and sediment samples of the Paraopeba and the Das Velhas Rivers in the state of Minas Gerais, Brazil to assess the impact of mining activities on the water environment. Elemental concentrations of Cr, Fe, Co, Ni, Cu, As, Cs, Ba, La and Ce were measured in water an...
