the sanganeh formation crops out throughout the kopeh-dagh basin and is mainly composed of shale and marl with interbeds of siltstone and limestone. in this study, the sanganeh formation, with 550 meter thickness, has been studied at north of the sanganeh village in eastern parts of the basin. according to distribution of organic matter content, four palynofacies types are identified. the main ...

have continued to use the same analytical system (that is, the same sample preparation and decomposition methods, with atomic absorption spectroscopy as the final determination step) to determine 13 elements in stream and lake sediments collected for the RGS program. In the early 1980s, simultaneous determination of 30 elements or more by inductively coupled plasma emission spectroscopy (ICP-ES...

n this study, the elemental status of hair adolescent girls in Orenburg region (n=120) with different levels body mass index was studied and their average daily diet evaluated. A nutrition assessment program used to study diet. Estimation element carried out through chemical composition by ICP-AES ICP-MS. It found that there a general imbalance elements all groups, students obesity had lower co...

After a catastrophic 9.0 magnitude earthquake struck the east coast of Japan in April 2011, a chain of events was set in motion leading to the release of several volatile radionuclides of Cs and I into the atmosphere due to explosions in three of the six reactor cores at the Fukushima-Daiichi Nuclear Power Plant (FDNPP). This study shows the enrichment of stable Cs relative to other alkali meta...

In this study, geochemical and particle size analyses of thirty-four street sediment samples collected from an urban environment around Guanabara Bay, shows highway run-off to be a potential source of heavy metals for the pollution of near-shore sedimentary deposits. Concentrations of Fe, Mn, Zn, Cu, Pb, Cr and Ni were found to be higher in these sediments when compared to concentrations found ...

Present study consists geochemical variations and spatial distribution of trace elements (Fe, Mn, Cr, Co, Cu, Ni, Pb and Zn) of the ocean floor sediments collected along the continental shelf off East coast Tamil Nadu (Chennai to Velanganni) during the 2009 southwest monsoon period. Results indicate sand dominance with abundant calcareous debris and shell fragments. Normalisation of trace metal...

Introduction: The early history of the Moon, namely the first ~700 My following its formation, was an era marked by the formation of 43 basins (impact craters >300 km in diameter) [1,2,3]. Basin formation during this period had significant effects on the entire lunar crust; material from depth was excavated and redistributed across the entire surface [4]. The material redistributed by basins ca...

The present study aimed to calculate the water quality index (WQI) by the study of nine physico-chemical parameters on the basis of Weighted Arithmetic Index in order to assess the suitability of water for drinking purpose and other human uses in Ranebennur Taluka, Haveri District, Karnataka, India. WQI, a tool of rating water quality, is a valuable model to assess spatial and temporal changes ...
