Since Fleming discovered penicillin in 1929, thousands of antibiotics have been extensively used in medical treatment, farming and animal husbandry. However, 50%-80% of antibiotics used are excreted as parent compounds and primary metabolites in feces and urine. Numerous studies have reported the occurrence of antibiotics in wastewater, surface water, groundwater and soil. Antibiotics, as emerging contaminants, pose a threat to the ecological security due to their direct toxicity to organismsand induction of antibiotic resistant bacteria (ARBs) and the proliferation of antibiotic resistant genes (ARGs).
Given the environmental impacts and persistence of antibiotics, ARBs and ARGs, there is an urgent need to understand the fate, removal mechanisms and interaction mechanisms with microorganisms of common antibiotics during wastewater treatment, and take steps towards formulation of effective removal strategies. |
