he Suquía River middle-lower basin (Córdoba, Argentina) is subjected to a strong anthropogenic impactbecause it receives pollutants from different sources. The main goal of this study was to evaluate theintroducedfish species Gambusia affinis as a bioindicator of environmental pollution in the middle-lowerbasin of the Suquía River. The assessment was performed by measuring biomarkers at different levels ofbiological organization, at two sampling sites (before and after Córdoba city), and at dry and wet seasons.Water quality evaluation was made through a water-quality index (based on physico-chemicalparameters), heavy-metals and pesticides concentrations in water. The water quality varied betweensampling sites, showing the most degraded conditions downstream Córdoba city. The same pattern ofvariation was detected in the biomar
