The occurrence of pharmaceuticals in the environment can have undesirable effects on nontarget animals, including fish. The present experiment assessed the effects of subchronic exposure to waterborne acetaminophen (N-acetyl-p-aminophenol) (APAP) on selected behavioral aspects (physical avoidance response, ventilation rate, and food detection rate) and erythrocyte nuclear abnormality (ENA) in juvenile . Two groups of fish were exposed to APAP dissolved in aged municipal water (T: 2 mg/L and T: 10 mg/L) for 8 weeks in three replicates ( = 7 fish per tank), alongside a control group (C) without APAP.
