Zusammenfassung: | Among emerging contaminants, pharmaceuticals are one of the most relevant groups of substances found in aquatic environment, due to their universal use, specific physical-chemical properties, and mode of action in aquatic organisms at low concentrations. Considering the magnitude of concentrations and the considerable small amount of information about their potential ecotoxicological effects on wildlife (especially towards organisms from tropical areas), the present study intended to assess the acute and chronic effects of three pharmaceuticals (the analgesic acetaminophen, the anti-inflammatory diclofenac, and the antihypertensive propranolol) in the tropical crustacean species
