Occurrence and fate of PTE, PAH, and PFAS trace contaminants in soils and river suspended particulate matter in three DANUBEAN river catchments.

ABSTRACT: This study aimed to investigate the occurrence and concentration patterns of three groups of trace contaminants-potentially toxic elements (PTEs), polycyclic aromatic hydrocarbons (PAHs), and per- and polyfluoroalkyl substances (PFASs)-in river catchments with contrasting land use and landscape characteristics. A second objective was to relate the concentrations in suspended particulate matter (SPM) to those in soils and to catchment attributes in order to identify dominant transport processes and contaminant sources. A spatially explicit monitoring campaign was conducted in three river catchments of the central Danube River Basin: Zagyva and Koppány in Hungary and Wulka in Austria. Composite soil samples (∼10 per catchment, totaling ∼200 subsamples) were collected from forest, pasture, an
