We developed a novel, robust and quantitative analytical method for multi-elemental mapping of ancient glass, using the LA-ICP-MS technique. In each pixel of the maps, concentrations od 54 elemental oxides is determined. Subsequently, elemental maps are analyzed with image analysis software in order to understand ancient fabrication techniques, provenance of the artefact and its raw materials.

A "sequential" analytical methodology was developed - focusing on total Zn, spatial Zn distribution, extractability, chemical speciation and bioaccessibility of Zn and its species - to obtain information on zinc and its species in pumpkin seeds, and their possible degradation in the human gastrointestinal tract. It was shown that under simulated stomach conditions the zinc species identified completely decompose to Zn2+, which may become less bioavailable under intestinal conditions, possibly due to complexation with antinutrients such as phytate.

A new type of the antimony electrode based on a carbon paste bulk-modified with antimony powder (Sb-CPE) was presented for measuring μg L-1 concentration levels of Cd(II) and Pb(II) with square-wave anodic stripping voltammetry in 0.01 M HCl. The Sb-CPE exhibited highly linear response in the examined concentration range with favorable LoDs of 1.4 μg L-1 for Cd(II) and 0.9 μg L-1 for Pb(II). Its applicability was demonstrated through the analysis of real tap-water sample.
