“…Desorption testing from the present study showed positive hysteresis for both compounds, suggesting that whatever amount of these two compounds were adsorbed to soil, they would not desorb readily after a single desorption cycle. Similar hysteresis was also reported for other organic compounds (e.g., Weber et al, 1998;Sukul et al, 2008;Peng et al, 2014). And organic matter in soil could play an important role in hysteresis phenomena from desorption isotherms as observed in previous studies (Carroll et al, 1994;Mersie and Seybold, 1996;Weber et al, 1998;Sukul et al, 2008).…”

“…The sandy Kaldenkirchen soil especially favors the microbial activity. The high degradation rate may result from i) a higher hydraulic conductivity that increases the oxygen migration through the soil and ii) lower pH values in the KAL soil as SDZ becomes persistent in anoxic soils and at pH values larger than 6.5 (Sukul et al, 2008b).…”

Based on small-scale laboratory and field-scale lysimeter experiments, the sorption and biodegradation of sulfonamide sulfadiazine (SDZ) were investigated in unsaturated sandy and silty-clay soils. Sorption and biodegradation were low in the laboratory, while the highest leaching rates were observed when SDZ was mixed with manure. The leaching rate decreased when SDZ was mixed with pure water, and was smallest with the highest SDZ concentrations. In the laboratory, three transformation products (TPs) developed after an initial lag phase. However, the amount of TPs was different for different mixing-scenarios. The TP 2-aminopyrimidine was not observed in the laboratory, but was the most prevalent TP at the field scale. Sorption was within the same range at the laboratory and field scales. However, distinctive differences occurred with respect to biodegradation, which was higher in the field lysimeters than at the laboratory scale. While the silty-clay soil favored sorption of SDZ, the sandy, and thus highly permeable, soil was characterized by short half-lives and thus a quick biodegradation of SDZ. For 2-aminopyrimidine, half-lives of only a few days were observed. Increased field-scale biodegradation in the sandy soil resulted from a higher water and air permeability that enhanced oxygen transport and limited oxygen depletion. Furthermore, low pH was more important than the organic matter and clay content for increasing the biodegradation of SDZ. A numerical analysis of breakthrough curves of bromide, SDZ, and its TPs showed that preferential flow pathways strongly affected the solute transport within shallow parts of the soil profile at the field scale. However, this effect was reduced in deeper parts of the soil profile. Due to high field-scale biodegradation in several layers of both soils, neither SDZ nor 2-aminopyrimidine was detected in the discharge of the lysimeter at a depth of 1 m. Synthetic 50 year long simulations, which considered the application of manure with SDZ for general agricultural practices in Germany and humid climate conditions, showed that the concentration of SDZ decreased below 0.1 μg/L in both soils below the depth of 50 cm.

“…Nevertheless, many studies have suggested that OC plays a major role in the sorption of sulfonamides to soils and sediments. 38,39 Thiele-Bruhn and Aust 33 reported a higher adsorption of sulfonamides in soils with higher OM content, although this relationship appears to be valid only when considering soil organomineral particles. Thiele-Bruhn 1 also claimed that the effect of SOM on sulfonamide adsorption depends not only on its quantity but also on its composition.…”
