Petry-Podgórska, Inga ; Matoušek, Tomáš ; Migašová, M. ; Zemanová, Veronika ; Pavlík, Milan ; Pavlíková, D. ; Kratzer, Jan
This work was focused on an analysis of arsenic in selected plants and mercury in hair. A combination of HPLC and ICP-MS was used for analysis of biological tissues extracts. The\nspeciation analysis of low molecular arsenic and mercury species like inorganic iAs3+ and iAs5+, methylarsenic and dimethylarsenic forms was carried out with hydride generation (HG)\ntechnique, arsenic peptides and inorganic mercury (iHg2+) and its methylated form (MHg+) - with reverse phase (RP) chromatography and detected by ICP-MS.
