The concentration of Al, Cr, Fe, Mn, Ni, Cu, Zn, Hg, Sr, Mo, Ag, Cd, Pb and As was analyzed in water,sediment, and muscle of Odontesthes bonariensis from the eutrophic San Roque Lake (Córdoba-Argentina).The monitoring campaign was performed during the wet, dry and intermediate season. The concentrationof Cr, Fe, Pb, Zn, Al and Cd in water exceeded the limits considered as hazardous for aquaticlife. The highest metal concentrations were observed in sediment, intermediate concentrations, in fishmuscle, and the lowest in water, with the exception of Cr, Zn, As and Hg, which were the highest in fishmuscle. Potential ecological risk analysis of heavy metal concentrations in sediment indicated that theSan Roque Lake posed a low ecological risk in all sampling periods.The target hazard quotients (THQs) and carcinogenic risk (CR) for individual metals showed that As inmuscle was particularly hazardous, posing a potential risk for fishermen and the general populationduring all sampling periods. Hg poses a potential risk for fishermen only in the intermediate season. It isimportant to highlight that none of these two elements exceeded the limits considered as hazardous foraquatic life in water and sediment. This result proves the importance of performing measurements ofcontaminants, in both abiotic and biotic compartments, to assess the quality of food resources. Theseresults suggest that the consumption of this fish species from this reservoir is not completely safe forhuman health.
