Dissolved Cd concentrations in river water samples from the Koppány and Zagyva catchments at low and high water discharges, using two sample preservation procedures. Cd concentrations were determined by ICP-MS. Measurement uncertainty is better than ± 3%

Purpose
According to standard procedure recommended by the Water Framework Directive (WFD), dissolved concentrations of potentially toxic elements (PTEs) in river water are determined by inductively coupled plasma mass spectrometry (ICP-MS) in filtered (0.45 µm) and acidified (pH 2) samples. Properly prepared and stored composite samples can enhanc...

... Four published articles consider freshwater environments focusing on river transport, land degradation, and distribution of contaminants. Analytical challenges in different sample preservation procedures of potential toxic elements (PTEs) in river water are presented by Milačič et al. (2023). The focus is on the potential co-precipitation of PTEs with calcium carbonate (CaCO 3 ) in low-temperature storage conditions, which could affect analytical results. ...
