	abstract = {The H-D exchange processes in MHn or MDn hydrides (M = As, Sb, Bi, n = 3; M = Ge, Sn, n = 4) taking place when they are in contact with H2O or D2O solution at different pH or pD values (interval of pH = [0,13]) have been investigated using gas chromatography-mass spectrometry (GC-MS). MHn or MDn compounds were injected into the headspace of reaction vials (4-12 ml) containing 1-2 ml of buffered solution maintained under stirring or shaking conditions. The isotopic composition of the gaseous phase hydrides/deuterides was determined at regular intervals in the range of time 0-15 min. The MHn or MDn compounds were synthesized in separate vials and their purity was checked separately before injection into the reaction vials. The mass spectra were deconvoluted in order to estimate the relative abundance of each species formed following the H-D exchange process (AsHnD3-n, SbHnD3-n, BiHnD3-n, n = 0-3; GeHnD4-n, SnHnD4-n, n = 0-4) and the relative abundance of H and D. In the investigated pH (or pD) interval arsanes and stibanes undergo H-D exchange in alkaline media for pH > 7. No H-D exchange was detected for the other hydrides, where the prevailing process is their decomposition in the aqueous phase. A reaction model, based on the formation of protonated or deprotonated intermediates is proposed for H-D exchange of MHn or MDn compounds placed in contact with H2O or D2O at different pH or pD values. The H-D exchange in the already formed hydrides can be source of the interference in mechanistic studies on hydride formation performed using labeled reagents; no H-D exchange was detected within the following pH intervals that can be considered free from interference: arsanes pH = [0,7), stibanes pH = [0,7), bismuthanes, germanes and stannanes pH = [0,13]. © 2006 Elsevier B.V.

Standard reference concentrations - internal standards - of Fe in the two leaf samples were measured using the method of Relaxation Weighted Magnetic Resonance Imaging. From the spectra obtained using Laser Induced Breakdown Spectroscopy technique, spatial distribution of Fe within the leaf was identified. Thus, this technique could potentially be used as a complementary technique for identification of storage and trafficking of iron ions within different plant compartments. In particular, individual plant cells can be investigated without collateral damage with high spatial distribution.},

A simple and highly sensitive SPME-GC-pyrolysis-AFS system was used to analyse the aqueous MeHg and EtHg standard solutions after derivatization with sodium tetraphenylborate (NaBPh4). Samples were irradiated in a microwave digester at microwave powers ranging from 20 to 160 W for durations of 2 to 10 min. The different tolerances towards microwave treatment of the two organomercury species were evident. Practically no degradation was experienced for MeHg for up to 8 minutes of irradiation at 120 W or for up to 4 minutes at 160 W. Significant analyte loss was observed for EtHg after 2 minutes at 40 W of microwave power.},
