Antibiotic contamination poses serious risks of ecotoxicity and resistance gene induction. Advanced oxidation processes (AOPs) have demonstrated effectiveness in the degradation of antibiotics. However, the production of degradation intermediates in the oxidation process raises concerns about potential ecological risks. In-depth investigations on the ecotoxicity and resistance genes induction of antibiotic degradation products are important for addressing the environmental problems of antibiotics.
Antibiotic contamination could cause serious risks of ecotoxicity and resistance gene induction. Advanced oxidation processes (AOPs) such as Fenton, photocatalysis, activated persulfate, electrochemistry and other AOPs technologies have been proven effective in the degradation of high-risk, refractory organic pollutants such as antibiotics. However, due to the limited mineralization ability, a large number of degradation intermediates will be produced in the oxidation process. The residual or undiscovered ecological risks of degradation products are potential safety hazards and problems necessitating comprehensive studies. In-depth investigations especially on the full assessments of ecotoxicity and resistance genes induction capability of antibiotic degradation products are important issues in reducing the environmental problems of antibiotics. Therefore, this review presents an overview of the current knowledge on the efficiency of different AOPs systems in reducing antibiotics toxicity and antibiotic resistance.
