- Abstract
Abstract The removal efficiency of pharmaceuticals in wastewater treatment plants (WWTPs) is variable and some of these compounds pass these plants almost intact and others presenting a removal efficiency close to 100%. Their incomplete removal results in a continuous discharge of pharmaceuticals into the environment. To assess the profile of contamination of influents and effluents over a day, a set of 83 pharmaceuticals were evaluated hourly in a WWTP in Leiria, Portugal. The composite samples of the influent and effluent were also collected. Concentrations varied from
1 in WWTP influents, and carbamazepine, fluoxetine, sertraline the pharmaceuticals with an RQ > 1 in WWTP effluents. Graphical abstract Unlabelled Image Highlights • Hourly variation of 83 pharmaceuticals in WWTP influent and effluent is presented. • Pharmaceuticals belonging to different therapeutic classes were analysed. • Some pharmaceuticals were detected in the influents in the μg/L range. • The importance of the determination of metabolites and transformation products is highlighted.
