Composting is a cost-effective approach for the removal of antibiotics from the environment; however, the consequence of this approach on fluoroquinolone antibiotics is limited. The fate of five representative fluoroquinolone antibiotics, namely ciprofloxacin, enrofloxacin, lomefloxacin, norfloxacin, and sarafloxacin, was investigated in a pilot-scale composting of broiler manure over 42 days. The effect of antibiotic concentrations (at a dose of 15, 30, or 60 mg/kg for each and a control without antibiotic addition) on the composting process was also assessed. The 42-day composting showed 45.3–75.4% of antibiotic removal with species-specific patterns. However, the observed variations in such removal among both antibiotics concentrations and composting times were not significant in most cases, possibly indicating a slight side-effect of the tested antibiotic concentrations on the composting process. To the best of our knowledge, this study is among few studies with a focus on the persistence of fluoroquinolone antibiotics during a pilot-scale composting, which warrants further study in regards to the mechanism underlying the removal of these compounds during composting.
