Graphical abstract of the publication "Between Underground and the Deep Blue Sea: Contamination of Mine Water Effluents by Polychlorinated Biphenyls (PCBs)" published in ACS EST Water 2023. Presented is a drawing of flooded mine tunnels from which water is pumped and discharged to rivers. A low volume sample aliquot is shown for analysis by SPME. Additionally, an excerpt of a bar chart is shown with congener specific PCB concentrations.

From the ClayHOC project: our publication on adsorption of the hydrophobic organic pollutant hexachlorobenzene (HCB) to phyllosilicate minerals

Read more (Environmental Science and Pollution Research, open access):
doi.org/10.1007/s113...
Photography of the 12 natural phyllosilicate clays used in the publication. The clays are in powder form on a ceramic plate and show different colours (e.g. white, grey, brown, ...). Photo: Leonard Böhm Figure 1 from the publication (Böhm et al. 2023 ESPR, https://doi.org/10.1007/s11356-022-24818-4). Adsorption isotherms for the interaction of HCB with the cation-modified clay mineral montmorillonite STx-1b. Homoionic cation exchange was performed with a) alkali metal cations, and b) alkaline earth metal cations (clay mineral concentration: 10 g L−1; particle size fraction: < 2 µm, HCB concentration: 1–5 µg L−1). Note different scales of y-axes. All isotherms in Fig. 1b are in the range of adsorption to Na+-modified montmorillonite in Fig. 1a Left panel shows increasing adsorption with increasing radius of alkali metal cations used for cation-exchange (except for Li that is comparable with K). Right panel shows equal adsorption independant of radius of alkaline earth metal cations used for cation-exchange. Figure 2 from the publication (Böhm et al. 2023, ESPR, https://doi.org/10.1007/s11356-022-24818-4) Adsorption of HCB in the presence of cation-exchanged montmorillonite (CMS, STx-1b). Exchange was performed with alkali and alkaline earth metals. Left panel shows relation between log Kd and the period of table of elements: log Kd is increasing depending on increasing atomic number after alkali cation modification of clay, but not after alkaline earth cation modification of clay. Right panel shows relation between log Kd and hydrated radius: Higher hydrated radius of alkaline earth cations compared to hydrated radius of alkali cations shows grouping without overlapping.
