!--[if gte mso 9]> In South America, there is a lack of data concerning occurrence and levels of pharmaceuticals in main rivers as well as their negative effects on the biota. Here we report the occurrence as well as the spatial and temporal variations of some common prescribed pharmaceuticals in the Suquía River basin (Córdoba, Argentina). We also report the bioconcentration of two of them in Gambusia affinis, a widely distributed fish species inhabiting the river basin. The influence of the wastewater treatment plant of Córdoba city was critical (up to 70 km downstream). Among 15 compounds analyzed, atenolol, carbamazepine and diclofenac were the most f
