Conventional methods are based on atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS).
The conventional methods for determining Mn are based on atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICPMS).
Most of them are based on atomic absorption spectroscopy (AAS) [ 11– 15], atomic fluorescence spectroscopy (AFS) [ 6, 16, 17], inductively coupled plasma optical emission spectrometry (ICP-OES) [ 18] and inductively coupled plasma mass spectrometry (ICP-MS) [ 19– 23].
The 3D model can be built based on atomic positions, and colored based on atomic charges, or built based on residue positions, and colored based on residue charges.
Our definition of burial level is based on atomic contact graph.
Several methods have been reported for Pb2+ and Cr3+ determination based on electrothermal atomic absorption spectrometry [3, 4], X-ray fluorescence [5], chromatography [6], electrochemical methods [7, 8, 9], mass spectroscopy [10, 11] and photometric methods [12].
Each specimen was analyzed for Pb in duplicate, using a method based on electrothermal atomic absorption spectrometry (ETAAS) with longitudinal Zeeman-effect background correction.
All analytical measurements for blood lead were carried out in the Wadsworth Center's Lead Poisoning and Trace Elements Laboratory (Albany, NY), using a well-established method based on electrothermal atomic absorption spectrometry (ETAAS) (Parsons and Slavin 1993).
Different definitions for heavy metals have been proposed based on density, atomic number or atomic weight, chemical properties and toxicity.
