Comprehensive study of ibuprofen and its metabolites in activated sludge batch experiments and aquatic environment

► Fast quantification of ibuprofen and its metabolites in batch studies, real wastewater and river samples ► First detection of 1,2-dihydroxy ibuprofen in activated sludge batch experiments ► First removal study of ibuprofen metabolites in activated sludge batch experiments ► Very high levels of metabolites in comparison to ibuprofen in real influent, effluent and river water
