“…Final disposal of effluents from treated and untreated wastewater contains toxic metals from different industries, as well the indiscriminate use of fertilizers and pesticides, which contain heavy metals, can contaminate the quality of the water (Ammann, 2002;Gowd & Govil, 2008;Islam, Han, Ahmed, & Masunaga, 2014;Jarvie, Whitton, & Neal, 1998;Jonnalagadda, Mathuthua, Odipo, & Wandiga, 1991;Jonnalagadda & Mhere, 2001;Kar, Sur, Mandai, Saha, & Kole, 2008;Lantzy & Mackenzie, 1979;Mathuthu, Zaranyika, & Jonnalagadda, 1993;Nriagu, 1979;Simeonov et al, 2003;Srebotnjak, Carr, de Sherbinin, & Rickwood, 2012;Su et al, 2013). Within the Pampean Plain, numerous basins are affected by the discharge of industrial effluents, modifying not only the quality of water but also that of the sediments in the riverbed where metals tend to accumulate (Biruk et al, 2017;Cantera, Scasso, Tufo, Villalba, & dos Santos Afonso, 2018;Castro, Rendina, & Orgeira, 2018;Magdaleno, de Cabo, Arreghini, & Salinas, 2014;Mendoza, García, de Cabo, Weigandt, & de Iorio, 2015;Rendina, Bargiela, Cabo, Arreghini, & Iorio, 2001). The Samboromb on River basin comprises a mainly agricultural-livestock region where populated centers and some industries such as battery factory, tannery or car assembly factories, among others are located only in the headwaters sector.…”

Chemistry of surface water and groundwater can be conditioned by geology, anthropic influence, and exchange of flow between them. The Pampean Plain located in Argentina has gaining streams and mainly rural activities. An increase in the concentration of chemical values of surface waters with respect to groundwater can be attributed to the anthropogenic contribution. The aim of this work was to identify the natural and/or anthropic processes that determine the chemistry of surface water and groundwater in a sector of the Pampean Plain of Argentina through the analysis of major and trace elements, 18 O and 2 H isotopes, and statistical tools. A surface water and groundwater sampling network was designed, where physicochemical parameters were measured, and samples were taken to determine major and trace elements and stable isotopes of water. The results indicate that dissolution, cation exchange, and evaporation are the main processes that determine the chemistry of the major elements associated with natural processes without showing evidence of anthropic involvement. Some trace elements that are statistically associated with major ions evidence water-sediment interaction within the aquifer. On the other hand, trace elements, as heavy metals, present a higher concentration in surface water compared to groundwater. This fact, evidences an anthropogenic contribution attributable to anthropic activities. The multivariate statistical analysis allowed discriminating between those trace elements associated with natural processes from those influenced by anthropic activity, even when these elements' concentration was very low.

“…Contamination assessment of stream sediments depends on the accurate determination of the background values. To assess the degree of contamination and evaluate the adequate background for determining anthropogenic contamination in Cd, Cr, Cu, Ni, Pb and Zn in bed sediments of the Pampean area river basin, Castro et al [25] calculated the I geo values using selected lithogenic backgrounds (loess, loessial sediments and paleosoils), the metal concentrations of riverbed sediments in the residual fraction and the global average shale (ASTW) [26]. Magni et al [27] used the ASTW to evaluate the anthropogenic contamination of Cd, Cr, Cu, Ni, Pb and Zn in riverbed sediments of the Pampean area of Argentina.…”

Concentration, Spatial Distribution and Potential Ecological Risk of Heavy Metals in Stream Sediments of the Misiones Province, Argentina

One hundred and twenty-eight stream sediment samples were collected in the Misiones province of Argentina by the low-density geochemical mapping project of the China Geological Survey. The analyzed data were used to study the concentration, spatial distribution, local pollution level and potential ecological risk of eight heavy metals (As, Cd, Cr, Cu, Hg, Ni, Pb and Zn) by factor analysis, geoaccumulation index (Igeo), enrichment factor (EF) and the Hakanson’s potential ecological risk index (Eir and RI) methods. Results showed that the background values (median) of those elements were 2.97 ppm, 0.13 ppm, 212.60 ppm, 322.53 ppm, 0.013 ppm, 64.42 ppm, 12.58 ppm, and 198.85 ppm, respectively. Except for Hg, the contents of other elements were higher than the abundance of continental crust. The spatial distribution of Cu and Zn in stream sediments were consistent, while that of other elements were different. The factor analysis results implied that Cd, Cr, Cu, Ni and Zn were mainly affected by geological background and inherited the characteristics of regional parent rocks. Furthermore, Pb was not only controlled by natural conditions but also related to human activities, while As and Hg represented the anthropogenic sources, and their concentrations were affected by human activities. The results of Igeo and EF told us that Cu was heavily polluted in stream sediments; Pb and Zn were largely mildly polluted; As, Cr, Cd, Ni and Hg were mostly nonpolluted. The ecological risks were ordered as As > Cu > Cd > Pb > Hg > Cr > Ni > Zn. In general, the potential ecological risk of heavy metals in the Misiones province was low, but As and Cu also have a high ecological risk at some sampling points, which should be considered.

“…where (M/Al) sample is the ratio of the trace elements and aluminum content of the sediments, while (M/ Al) Loess is the ratio between the concentrations of the trace elements and aluminum of selected background (Castro et al, 2018;Simex & Helz, 1981). The 0 B EF \ 1 indicates no enrichment (Level I), 1 B EF \ 3 indicates minor enrichment (Level II), 3 \ EF \ 5 indicates moderate enrichment (Level III), 5 B EF \ 10 indicates moderately severe enrichment (Level IV), 10 B EF \ 25 corresponds to severe enrichment (Level V), 25 B EF \ 50 is assigned to very severe enrichment (Level VI), and EF C 50 is attributed to extremely severe enrichment (Level VII).…”

The mineralogical and geochemical characterization of sediments of the Reconquista River allows analyzing the geochemical partition of trace elements in one of the most polluted water courses of Argentina. The low dissolved oxygen and high ammonia contents, together with the high chemical oxygen demand, attest to the poor water quality. Ammonia, Cd and Cu content in surficial water exceeds the maximum guidelines for freshwater in Argentina. The recent sediments of the uppermost bed are enriched in organic matter (OM), sulfur, Zn, Cu and Pb. The enrichment factor is moderate, and the geoaccumulation index (Igeo) for Cu and Pb indicates uncontaminated to moderately contaminated sediments. The positive and significant correlation between As, Cr, Pb and Zn with the iron content suggests that their retention is controlled by the amount of iron oxy (hydr)oxides in the sediments, probably combined with the silt ? clay abundance. In comparison with its tributary, the Las Catonas Stream, the Reconquista River, has less OM and trace elements in the sediments and more dissolved trace elements in the interstitial water. We interpret that OM is the main
