ABSTRACT
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 cells proliferation in fish gills and bioaccumulation of chromium and manganese in muscle evidenced higher impacts at S2, whereas a higher genotoxic potential was observed at S1. Gill histopathological alterations were found in fish captured at both sampling sites. Temporal variations in all biomarkers analyzed and bioaccumulation of manganese and nickel were observed at S1, whereas only variations in condition factor, gill alterations and bioaccumulation of manganese and aluminum were found at S2. Our study evidences that S1 is under minor anthropogenic impacts and that the high urbanization at S2 reflects in a poor water quality. Nonetheless, the human consumption of fish from the Paranhana River should be avoided given the high concentrations of cadmium, chromium and lead.
