- Abstract:
- The potential toxicity of antibiotics and other emerging contaminants in water has attracted widespread attention. Chlorinated disinfection by-products (DBPs) can be produced from sulfonamide antibiotics during the chlorine disinfection process, resulting in risks to human health. In this study, the transformation pathways of sulfonamide antibiotics in the disinfection processes using free chlorine (FC), chlorine dioxide (ClO2), and UV/FC are summarized, respectively. The toxicity of the chlorinated DBPs is discussed. In addition, the potential effects of these chlorinated DBPs from sulfonamide antibiotics on the bacterial resistance and horizontal gene transfer were also studied. Finally, the future research directions of sulfonamide antibiotics as precursors of chlorinated DBPs in water are proposed. The purpose of this work is to provide basis for ecological risk assessment and pollution control of sulfonamide antibiotics during chlorine disinfection.
