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