Volatile hydrides of As, Se, Sb, Sn and Bi were generated from aqueous sample solutions using a tetrahydroborate reductant. The gaseous analytes were...
Saline Ca-Na/Cl type groundwaters and brines sampled in deep mines over an extensive area of the Canadian Precambrian Shield have elevated BrCl ratios which...
A rapid method for the determination of total and inorganic mercury in biological tissues is presented using electrothermal vaporization inductively coupled...
Spectrochimica Acta Part B: Atomic Spectroscopy, 1993, Volume : 48, Numéro : September 11
The formation of background polyatomic ions in electrothermal vaporization inductively coupled plasma mass spectrometry is reported. Vaporization temperatures...
This study presents the abundances of Ru, Ir, Pt, Pd, Rh, and Au (platinum-group elements; PGE) in the ejecta layer at the Cretaceous-Tertiary boundary and...
Ruthenium and Ir are the least mobile platinum group elements (PGEs) within the Cretaceous-Tertiary (K-T) boundary clay. The Ru/Ir ratio is therefore the most...
Basinal strata spanning the Late Ordovician extinction have been determined for major and trace elements, and isotopes of C, O and S. A marked increase in...
Grain size separates of the Cretaceous-Tertiary (K-T) fireball layer at marine sites and the entire K-T boundary interval at nonmarine sites (fireball layer,...
We report new Sr, S, and B isotopic data for evaporites (gypsum, anhydrite), carbonates, melt rocks, gneisses, and groundwaters recovered in and around the...
Some metal species in river surface water, rain and snow were characterized by size and molecular weight, using filtration and ultrafiltration, and by their...
