Four volcanic glass samples on the INternational focus group on Tephrochronology And Volcanism (INTAV) sample mount described by Kuehn et al. (2011) were analyzed to establish a new methodology for m...
Nisyros Island, Greece, is a stratovolcano known for its intense hydrothermal activity. On June 2013, during a multidisciplinary field campaign, soil samples were collected in the caldera area to dete...
Since the late 1990s there has been a growing impetus for a comprehensive global study of the marine biogeochemical cycles of trace elements and their isotopes (TEIs). This has led to the development ...
Biogenic coalbed methane (CBM), an end product of anaerobic coal biodegradation, is a natural gas. It is generated and trapped in large quantities in deep, unmineable coalbeds. This dissertation descr...
Annex 3 to: Trace elements mobility in soils from the hydrothermal area of Nisyros (Greece) .
All soil samples were air dried, thoroughly mixed and split into subsamples for analysis. Particular care was taken using a Riffle-type sample splitter to ensure that representative subsamples were ob...
The atmospheric concentrations of nonsea-salt (nss) SO4 2– and trace elements (As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sb, Se, V, and Zn) were measured for aerosol samples collected concurrently at ten site...
Water–rock interaction processes and trace elements distribution were studied in the Triassic dolomite aquifers of Sassolungo and Sella group (Dolomite mountains, northern Italy). These systems consi...
The Daliao River System (DRS) estuary in the Liaodong Bay has a highly industrial, urbanized, and agricultural catchment. The objective of this study was to investigate the multi-elemental geochemist...
The distributions of trace elements in ferromanganese concretions (FMCs) and the surrounding terra rossa (TR) matrix overlying dolomite have been examined to extend our understanding of their mobiliz...
This study states the potential trace elements (TE’s) content of red soils located at the centre region of Spain, characterized by low rainfall and slight acidity over prolonged weathering periods. Fo...
Using laser-ablation inductively coupled plasma mass spectrometer (LA-ICPMS), we have improved the reliability of the abundance data for trace-elements in geochemical samples using a glass bead ablat...
In an effort to understand and quantify the impact of local, regional, and far-distant atmospheric mercury sources to rainfall mercury deposition in the Pensacola, Florida watershed, a program of even...
Colloidal size spectra of Fe, Cu, Ag, La, and Pb were determined by asymmetrical flow field–flow fractionation coupled to high-resolution inductively coupled plasma mass spectrometry, in samples from ...
The liver is known to accumulate many trace elements; thus it is very important to determine their level in a sensitive way. The objective of this study was to develop a simple method for the simultan...
