Journal ArticleDOI
Occurrence of antibiotics and antibiotic resistance genes in hospital and urban wastewaters and their impact on the receiving river.
Sara Rodríguez-Mozaz,Sara Chamorro,Elisabet Marti,Belinda Huerta,Meritxell Gros,Alexandre Sànchez-Melsió,Carles M. Borrego,Damià Barceló,José Luis Balcázar +8 more
TL;DR: A widespread occurrence of antibiotics and ARGs in urban and hospital wastewater and how these effluents, even after treatment, contribute to the spread of these emerging pollutants in the aquatic environment is demonstrated.
Journal ArticleDOI
Occurrence, partition and removal of pharmaceuticals in sewage water and sludge during wastewater treatment.
Aleksandra Jelic,Meritxell Gros,Antoni Ginebreda,Raquel Cespedes-Sánchez,Francesc Ventura,Mira Petrovic,Mira Petrovic,Damià Barceló,Damià Barceló +8 more
TL;DR: Most of the substances are incomplete and improvements of the wastewater treatment and subsequent treatments of the produced sludge are required to prevent the introduction of these micro-pollutants in the environment.
Journal ArticleDOI
Removal of pharmaceuticals during wastewater treatment and environmental risk assessment using hazard indexes
TL;DR: In a long term study, a total of 84 samples from seven WWTP located in the main cities along the Ebro river Basin as well as receiving river waters were analyzed to assess the occurrence of 73 pharmaceuticals covering several medicinal classes, results indicated that pharmaceuticals are widespread pollutants in the aquatic environmental.
Journal ArticleDOI
Development of a multi-residue analytical methodology based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) for screening and trace level determination of pharmaceuticals in surface and wastewaters.
TL;DR: The developed analytical method was successfully applied to the analysis of pharmaceutical residues in WWTP influents and effluents, as well as in river water, and justifying the selection of internal standard calibration as the most suitable approach for this study.
Journal ArticleDOI
Fast and comprehensive multi-residue analysis of a broad range of human and veterinary pharmaceuticals and some of their metabolites in surface and treated waters by ultra-high-performance liquid chromatography coupled to quadrupole-linear ion trap tandem mass spectrometry.
TL;DR: The development of an analytical method, based on automated off-line solid phase extraction followed by ultra-high-performance liquid chromatography coupled to quadrupole linear ion trap tandem mass spectrometry (UPLC-QqLIT) for the determination of 81 pharmaceutical residues, covering various therapeutic groups, and some of their main metabolites, in surface and treated waters.
