“…Hydrophobic acid fraction (if present in the coatings) could again increase repulsion between the soil surface and negatively charged molecules of sulfamethoxazole. In the case of carbamazepine, sorption of its neutrally charged molecules (which should be mainly controlled by the organic matter content; Kodešová et al 2015;Kočárek et al 2016) did not substantially differ. When comparing the sorption affinities resulted from the different applications of the compounds (i.e., single and in a mixture) it is evident that the sorption of all three compounds did not decrease due to the competition between these compounds for the same sorption sites.…”

“…Three compounds (Table 2) were selected from a set of seven pharmaceuticals that have been applied previously by Kodešová et al (2015Kodešová et al ( , 2016 or by Kočárek et al (2016) in an evaluation of the impacts of soil properties on sorption affinities, or in an assessment of dissipation half-lives in various soils taken from 11 topsoils and 2 substrates. Pharmaceuticals (Table 2) were chosen based on their different forms depending on pH (Table 1) of the soil-water environment, their pKa values (Table 2) and their corresponding sorption behaviour (Kodešová et al 2015): atenolol (cation), sulfamethoxazole (anion) and carbamazepine (neutral).…”

Fér M., Kodešová R., Golovko O., Schmidtová Z., Klement A., Nikodem A., Kočárek M., Grabic R. (2018): Sorption of atenolol, sulfamethoxazole and carbamazepine onto soil aggregates from the illuvial horizon of the Haplic Luvisol on loess. Soil & Water Res., 13: 177−183.The leakage of pharmaceuticals present in soils towards groundwater is largely controlled by sorption of those compounds in soils. In some soils, soil aggregates are covered by coatings, which may have considerably different composition in comparison to that in an inner part of the aggregates. The aim of this study was to evaluate the sorption of three pharmaceuticals, which were applied in single or all compounds solutions, onto soil samples taken from the Bt horizon of a Haplic Luvisol. Analyses were performed on three types of disturbed soil samples: (1) entire aggregates, (2) aggregates from which coatings were removed, and (3) clay-organic coatings. Sorption of atenolol onto material from coatings was slightly higher than that onto material from the inner parts of the aggregates. On the other hand, sorption of sulfamethoxazole onto material from the coatings was lower than that from the aggregate interior. Both associates with a dominant fraction of clay particles (that are mostly negatively charged) in the coatings in comparison to soil composition in interiors and thus larger cation exchange capacity, which increased sorption of the positively charged atenolol and decreased sorption of the negatively charged sulfamethoxazole. Sorption of carbamazepine, which was in neutral form, did not substantially differ. The sorption of all three compounds did not decrease due to the competition between these compounds for the same sorption sites when applied simultaneously. Atenolol sorption was similar for both applications. Sorption of sulfamethoxazole increased when applied in solution with the other two compounds in comparison to its negligible sorption measured for the single compound solution likely due to sorption of the positively charged molecules of atenolol onto the negatively charged surface of soil components and reduction of repulsion between the soil components and the negatively charged molecules of sulfamethoxazole. Carbamazepine sorption also increased probably due to ionization of molecules due to dipole -induced dipole interaction between non-polar and polar molecules in solution.

“…Sorption coefficients for mixture of all compounds were not measured. Since sorption coefficients of all or some compounds should be impacted by their competition for sorption sites or synergy (Kočárek et al, 2016;Fér et al, 2018;Schmidtová et al, 2020), correlations between DT 50,M and evaluated K F were not calculated.…”

Soils groups according to basic soils properties and sorption of compounds matched. • Soils groups according to microbial community structure and half-lives corresponded. • Half-lives could be predicted using one microbial criterion and sorption coefficient. • Simultaneous application of all compounds mostly reduced their dissipation in soils. • The average increase in multiple-solute half-lives varied between 7 and 39%.

“…37 Moreover, the different sources of DOM inevitably affect its distribution characteristics and structural properties, degradation process and interaction with soil components, which ultimately affected the biogeochemical processes of DOM in farmland soil. [38][39][40] Similarly, in the latest studies, Martin et al 41 studied the sorption affinities of 4 pharmaceuticals applied in solute mixtures to soils taken from different horizons of 3 soil types. This experiment revealed that the content of organic matter would be different for various types of soil.…”
