The temporal variation of As, Co, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn in surface waters and sediments, and trace element accumulation and physiological changes in the macrophytes Stuckenia filiformis and Potamogeton pusillus, were estimated in the Ctalamochita River, Argentina, both upstream and downstream of Río Tercero. Chromium, Fe, Pb and Zn in surface water were higher at the downstream site, while Cu and Mn were higher upstream. Chromium, Mn and Zn in S. filiformis correlated with concentrations observed in sediments, whereas only Zn did in water. In P. pusillus, As, Co, Cr, Ni, Pb and Zn correlated with concentrations in sediments. P. pusillus revealed greater variations in the photosynthetic pigments and malondialdehyde content in the site downstream of the city than those observed in S. filiformis. Therefore, P. pusillus has a greater potential use in monitoring studies in aquatic environments with ecological risk than S. filiformis.

Freshwater and groundwater are important resources for the drinking water supporting agricultural and livestock activities in the Córdoba province, Argentina. The aim of this study was to assess the physicochemical and microbiological quality of surface water (n = 14) and groundwater (n = 17) sites in the middle-lower basin of the Ctalamochita River (Córdoba, Argentina) for human and animal consumption. A total of 18 physicochemical and five microbiological parameters were evaluated to determine the hydrogeological characteristics of both water resources and their suitability for human and animal consumption using the Water Quality Index (WQI).

A research gap exists in baseline concentrations of organic micropollutants in South American rivers. Identification of areas with different degrees of contamination and risk to the inhabitant biota is needed to improve management of freshwater resources. Here we inform the incidence and ecological risk assessment (ERA) of current used pesticides (CUPs), pharmaceutical and personal care products (PPCPs) and cyanotoxins (CTX) measured in two river basins from central Argentina (South America).

Surface water sources are greatly impacted in areas with major agricultural land use. The atrazine quantification in surface waters as well as the spatial-temporal patterns of this herbicide was studied to detect pollution hotspots and to understand the putative factors responsible of its occurrence at the Ctalamochita river basin. The samples were collected on the aeolian fluvial plain of the river basin during five consecutive years.

The aim of this study was to evaluate the ability of Palaemonetes argentinus to evidence the environmental degradation due to pollutants mixture in a freshwater aquatic ecosystem. For this purpose, an active monitoring (96 h exposure) was carried out in seven sites along the Ctalamochita River basin (Córdoba, Argentina), as a case of study. Our results evidenced sewage discharges impact in the water quality index, as well as metal pollution in water (Ag, Al, B, Pb, Hg) and sediments (Hg) with a potential effect on aquatic biota.
