Summary: Silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) can be extracted from their ions using magnetic dispersive micro-solid phase extraction with non-functionalised ferrite particles. The extraction is based on controlling the acidity of the medium, without involving oxidation-reduction processes. The analytes are desorbed and determined by electrothermal atomization atomic absorption spectrometry. The method has a high enrichment factor, low detection limits, and good reproducibility.

Summary: This study examined the mobility of potentially toxic elements (PTEs) in contaminated soils and road dusts in Volos, Greece. The results showed that lead and zinc had the highest remobilization potential, while nickel, chromium, and iron had low mobility. The extractability of PTEs in soil samples was controlled by carbonate content and organic matter, while magnetic susceptibility played a key role in the geochemical partitioning of PTEs in road dust. It was suggested that sequential extraction procedures should be combined with source identification of PTEs to better estimate their remobilization in soil and road dust influenced by industrial emissions.
