Fluoroquinolones are frequently found at high levels in hospital effluents, particularly in comparison to municipal wastewater . Fluroquinolone AAs are used to treat a range of infections, from, combined with their stability and they are often excreted as parent compounds in urine (30-85%) , explains their high prevalence in environmental matrices. Regarding CIP, the average levels in hospital effluent for the five days were reported at 0.9 ± 1.6 µg/L, in comparison to the yearly average of CIP in community wastewater at 0.52 ± 0.24 µg/L. The highest concentrations of CIP were reported on the 06/08/2019 in hospital effluent at 3.9 ± 0.5 μg/L. Similar variable concentrations of CIP have been reported elsewhere in hospital effluents , with some studies reporting significantly higher quantities, ranging 101-236 µg/L .
