ABSTRACT

In this study, we evaluated acute toxicity of four different pharmaceutical compounds: 17 α-ethinylestradiol (EE2), fluoxetine,diclofenac and ibuprofen to Daphnia similis. The average values of EC50 were 1.63 mg/L to the 17α-ethinylestradiol(EE2), 4.41 mg/L to the fluoxetine, 46.0 mg/L to the diclofenac and 97.0 mg/L to the ibuprofen. The effects of these drugs,in particular those caused to aquatic biota, still unknown especially at low concentrations in a range from ng/L up to mg/L.

Os valores médios de CE50 foram de 1,63 mg/L para 17 α-ethinylestradiol (EE2), 4,41 mg/Lpara fluoxetina, 46,0 mg/L para diclofenaco e 97,0 mg/L para ibuprofeno. Os efeitos desses fármacos, sobretudo à biotaaquática, ainda são pouco conhecidos especialmente em baixas concentrações na ordem de ng/L a mg/L.
