Abstract: The Paranhana River, located in Southern Brazil, is one of the major tributaries of the Sinos River basin and receives mainly industrial and domestic effluents. In the present study, water physicochemical and microbiological analyses, condition factor, micronucleus test, gill histopathology and metal bioaccumulation in the muscle of the native fish Bryconamericus iheringii collected at two sites (S1 and S2) of the Paranhana River under different degrees of anthropogenic pressures were assessed in four sampling campaigns. Data from water quality parameters, condition factor, mucous ce...
