Abstract In this study, we present a screening method based on molecular absorption spectrometry to study PFAS uptake and fate in plants. To evaluate the suitability of this method we analyzed plant extracts with molecular absorption spectrometry (MA

The presence of microplastic (MP) particles in aquatic environments raised concern about possible enrichment of organic and inorganic pollutants due to their specific surface and chemical properties. In particular the role of metals within this conte

Per- and polyfluoroalkyl substances (PFAS) are emerging organic pollutants and can occur in surface and groundwater. To identify the degree of pollution in surface water with PFAS, often targeted HPLC–ESI–MS/MS has been employed in which commonly

In this study, we compare analytical methods for PFAS determination–target analysis, non-target screening (NTS), direct total oxidizable precursor assay (dTOPA) and extractable organically bound fluorine (EOF). Therefore, suspended particulate matt

Combination of microdroplet generator and ICP-ToF-MS for nanoparticle sizing via on-line ID (on-line ID-MDG-sp-ICP-ToF-MS). 194Pt/195Pt ratio was used for sizing of the particles, while 182W/183W ratio used simultaneously for mass bias correction.

Highly transparent CeO2/polycarbonate surfaces were manufactured that prevent adhesion, proliferation, and spread of bacteria. CeO2 nanoparticles with diameters of 10-15 nm and lengths of 100-200 nm for this application were prepared by oxidizing aqu

A new approach relying on AF4 for gentle on-line removal of the ionic background from cells during single cell-ICP-ToF-MS analysis was developed. In a first proof-of-concept study the new approach was applied for the analysis of yeast cells.

The European Marine Strategy Framework Directive (MSFD) requires good ecological status of the marine environment. This also includes the Wadden Sea located in the southeastern part of the North Sea and its chemical status of sediments. Based on resu
