Concerns about the effect of sewage treatment plant (STP) effluent on he health of freshwater ecosystems have increased. In this sludy, a unique approach was designed to show the effect of an STP effluent-dominaled stream on naive wild brown Luna (Sohn trultu L.) exposed under fully natural conditions. Zivny stream is located in South Bohemia, Czech Republic. The downstream site of Zivny stream is an STP-affecled sire, which receives 25% of is wafer from Prachalice STP effluent.. Upsffeam, however, is a minimally polluted water site and i is considered Lo be the control sire. Native fish were collected from the upstream site, Lagged, and distributed W both upstream and downstream sites. After 30, 90, and 180 days, fish were recaptured from both sites to determine whether the downstream site of the Zivny stream is associated with the effects of environmental pollution. Several biomarkers indicating the oxidative stress and antioxidant enzyme activities, cytochrome P450 activity, xenoestrogenic effects, bacterial composition, and lipid composition were investigated. Additionally, polar chemical contaminants (pharmaceuticals and personal care products (PPCPs)) were quantified using polar organic chemical integrative samplers (POCIS). Fifty-three PPCPs were detected in the downstream site, 36 of those were constantly present during the 180-day investigation period. Elevated hepatic 7-benzyloxy-4trifluoromethylcoumarin-0-debenzyloxylase (BFCOD) (alter 90 days) and blood plasma vitellogenin concentrations in males were detected in fish downstream of the SIP effluent during all sampling events. An increase in the fishes' total fat content was also observed, but with low levels of omega-3 fatty acid in muscle tissue. Two bacterial taxa related to activated sludge were found in the intestines of fish from downstream. Our results show that Prachatice STP is a major source of PPCPs in the Zivny stream, which has biological consequences on fish physiology
