Adsorption of enrofloxacin in presence of Zn(II) on a calcareous soil

On the contribution of reclaimed wastewater irrigation to the potential exposure of humans to antibiotics, antibiotic resistant bacteria and antibiotic resistance genes – NEREUS COST Action ES1403 position paper

“…Once in the soil, these contaminants can interact with other pollutants such as metals or alkaline earth cations (Fe, Cu, Al, Ca), forming complexes or chelates, which dramatically modify their fate. Limited information exists on how these cations influence the effect and the fate of pollutants [26][27][28][29], and, hence, the ability of plants to uptake them.…”

Enrofloxacin—The Ruthless Killer of Eukaryotic Cells or the Last Hope in the Fight against Bacterial Infections?

“…The following facts have also been confirmed: the interaction of enrofloxacin with Cu 2+ ions via pyridone and carboxylate moieties [ 168 ], the modulation of binding of this antibiotic to the outer membrane protein OmpF of E. coli in the presence of Mg 2+ ions [ 169 ], and the increased adsorption of enrofloxacin in calcareous soil in the presence of Zn(II) [ 170 ] have all been observed. The list of other studies reporting the significant effects of enrofloxacin in combination with metals is presented in Table 5 .…”

The role of soil components in the sorption of tetracycline and heavy metals in soils

“…Sorption process plays a critical role in controlling mobility and bioavailability of contaminations in soil environment. 8,9 For different kinds of antibiotics and heavy metals, their structures and functional groups may be the main factors affecting their sorption behaviors. 1 Previous studies indicated that antibiotics and heavy metals might be sorbed on soils mainly via the electrostatic interaction between the positivecharged groups and the negative-charged sorption sites, or via the cation exchange between the positive-charged groups and the cations adhering to the surface of soil.…”

“…1 Previous studies indicated that antibiotics and heavy metals might be sorbed on soils mainly via the electrostatic interaction between the positivecharged groups and the negative-charged sorption sites, or via the cation exchange between the positive-charged groups and the cations adhering to the surface of soil. 9 The -OH and -CONH groups of antibiotics could be sorbed on the negativecharged sorption sites of soils via the cation bridging, and also be sorbed on the surface of metal oxide via the surface complexation with metal ions. 6 In addition, the sorption of these pollutions was further dependent on environmental factor (e.g., soil pH, soil texture, and cation exchange capacity).…”

“…[23][24][25][26] Although the co-sorption of antibiotics and heavy metals in soil has been widely investigated, it is still not clear that the effect of heavy metals on sorption of antibiotics on the separated components from natural soil. 9,17,27 In this study, tetracycline (TC), Cu 2+ and Cd 2+ were chosen as the representation of antibiotics and heavy metals. A natural black soil (BS) was used as a good sorption material as it represents a kind of typical Chinese soil with rich organic matter.…”
