Abstract: An assessment of the concentrations of thirteen different therapeutic pharmaceutical compounds was conducted\non water samples obtained from different wastewater treatment plants (WWTPs) using solid phase extraction and\nhigh- and ultra-high-performance liquid chromatography with mass spectrometry detection (HPLC-MS/MS and\nUHPLC-MS/MS), was carried out.\nThe target compounds included ketoprofen and naproxen (anti-inflammatories), bezafibrate (lipid-regulating),\ncarbamazepine (anticonvulsant), metamizole (analgesic), atenolol (?-blocker), paraxanthine (stimulant), fluoxetine\n(antidepressant), and levofloxacin, norfloxacin, ciprofloxacin, enrofloxacin and sarafloxacin (fluoroquinolone\nantibiotics).\nThe relative standard deviations obtained in method were below 11%, while the detection and quantification limits\nwere in the range of 0.3 ? 97.4 ng·L-1 and 1.1 ? 324.7 ng·L-1, respectively. The water samples were collected from\ntwo different WWTPs located on the island of Gran Canaria in Spain over a period of one year. The first WWTP\n(denoted as WWTP1) used conventional activated sludge for the treatment of wastewater, while the other plant\n(WWTP2) employed a membrane bioreactor system for wastewater treatment.\nMost of the pharmaceutical compounds detected in this study during the sampling periods were found to have\nconcentrations ranging between 0.02 and 34.81 ?g·L-1.
