Trace element concentrations are typically expressed in parts per million.
Trace element concentrations were determined by laser ablation ICP-MS and electron microprobe.
The second possibility also is unlikely, because there is no correlation, or rather an inverse correlation, between ash content and trace element concentrations.
Foliar trace element concentrations of Zn, Cr, Cu, Ni and sulfur are close to essential nutrient levels.
In this study we report Nd, Sr, Pb and Hf isotopes and multiple trace element concentrations of the Krishna lamproites.
Geostatistics has been used to map the probability that trace element concentrations in soil exceed or fall below particular thresholds.
Aaris-Sørensen, K., Rasmussen, K. L., Kinze, C. & Petersen, K. S.. Late Pleistocene and Holocene whale remains (Cetacea) from Denmark and adjacent countries: species, distribution, chronology, and trace element concentrations.
Whole-rock trace element concentrations were analyzed following the procedure of Ionov et al.59 adapted by for the analysis of ultra-depleted peridotites60 using an Agilent 7700x quadrupole ICP-MS at Géosciences Montpellier (Université Montpellier 2, France).
Sander, R. et al. Gas phase acid, ammonia and aerosol ionic and trace element concentrations at Cape Verde during the reactive halogens in the marine boundary layer (RHaMBLe) 2007 intensive sampling period.
Trace element concentrations in these samples were analysed by Inductively Coupled Plasma (ICP -mass spectrometry and ICP -massc emispectrometryometry (and).
These test programs included a range of fuel types with varying trace element concentrations, along with different combustion systems and particulate control devices.
