Occurrence and environmental risk assessment of pharmaceuticals in the Mondego river (Portugal).

ABSTRACT: In this case study pharmaceuticals were analysed in the Mondego river (Portugal) and their environmental risk assessed by means of risk quotients based on an extensive retrieval of ecotoxicological data for freshwater and saltwater species. The Mondego river crosses Coimbra, the most populated city in the Portuguese Centro Region hosting a complex of regional hospitals. Environmentally relevant and prioritised pharmaceuticals were investigated in this study and their potential hazards were evaluated by conducting a separate risk assessment for the freshwater and estuary parts of the examined river section. A target analysis approach with method detection limits down to 0.01 ng L^-1 was used to determine pharmaceuticals. Twenty-one prioritised target analytes out of seven therapeu
