Description:
Results of this study indicate that representative members of three environmentally relevant antibiotic classes – fluoroquinolones, sulfonamides, and dihydrofolate reductase (DHFR) inhibitors – are substantially degraded under conditions simulating chlorination of water supplies during disinfection processes, yielding a wide variety of lower and higher mass degradates. The mechanistic understanding of the reactions between chlorine and these three antibiotics classes provides a critical basis for predicting the fate of related antibiotics and pollutants in the chlorination disinfection processes.
