The compounds were extracted from water samples using Oasis HLB cartridges. The analytes were then identified and quantified using LC-MS/MS with dual-polarity electrospray ionisation in the MRM mode. Good linearity was obtained for all tested compounds (R2 > 0.99). The limits of detection (LODs) ranged between 0.15 and 24.0 ng l–1. Spike recoveries ranged from 84 to 115% and from 81 to 117% for urban wastewater and surface water samples, respectively, with satisfactory precision (RSD < 20%). Finally, the method was used to analyse real effluent and surface water.en-USPharmaceuticalsAntimicrobial agentsLC-MS/MSSurface waterWastewaterArticle
