“…Photocatalytic techniques, involving the activation of catalysts under light irradiation, offer an environmentally sustainable approach to the degrading of pharmaceutical compounds present in wastewater, achieving substantial removal efficiencies while minimizing energy consumption and chemical usage [33]. Additionally, the application of ultrasonic waves showed efficacy in disrupting pharmaceutical molecules and enhancing their removal from wastewater matrices under controlled conditions [34]. By integrating these advanced methods into wastewater treatment facilities, it is possible to achieve superior removal efficiencies, mitigate the environmental impact of pharmaceutical pollutants, and safeguard water quality for human consumption and ecosystem health.…”

A multi-residue UHPLC–MS/MS analytical method, previously developed for monitoring 52 pharmaceuticals in drinking water, was used to analyse these pharmaceuticals in wastewater originating from healthcare facilities in the Czech Republic. Furthermore, the methodology was expanded to include the evaluation of the effectiveness of drug removal in Czech wastewater treatment plants (WWTPs). Of the 18 wastewater samples analysed by the validated UHPLC-MS/MS, each sample contained at least one quantifiable analyte. This study reveals the prevalence of several different drugs; mean concentrations of 702 μg L−1 of iomeprol, 48.8 μg L−1 of iopromide, 29.9 μg L−1 of gabapentin, 42.0 μg L−1 of caffeine and 82.5 μg L−1 of paracetamol were present. An analysis of 20 samples from ten WWTPs revealed different removal efficiencies for different analytes. Paracetamol was present in the inflow samples of all ten WWTPs and its removal efficiency was 100%. Analytes such as caffeine, ketoprofen, naproxen or atenolol showed high removal efficiencies exceeding 80%. On the other hand, pharmaceuticals like furosemide, metoprolol, iomeprol, zolpidem and tramadol showed lower removal efficiencies. Four pharmaceuticals exhibited higher concentrations in WWTP effluents than in the influents, resulting in negative removal efficiencies: warfarin at −9.5%, indomethacin at −53%, trimethoprim at −54% and metronidazole at −110%. These comprehensive findings contribute valuable insights to the pharmaceutical landscape of wastewater from healthcare facilities and the varied removal efficiencies of Czech WWTPs, which together with the already published literature, gives a more complete picture of the burden on the aquatic environment.
