“…Pollution indices are widely applied to evaluate the enrichment of heavy metals from anthropogenic sources in a given geological medium (Jahan and Strezov 2018). Here, we used the metal pollution index (MPI) and the I geo to compare the pollution status of oxbow sediments.…”

Purpose Oxbow lakes, reaches that were cut off from a river during river straightening works, can accumulate during flooding metal-rich suspended sediments transported by a river from mining-impacted source areas and other anthropogenic sources. Additionally, the anthropogenic use of oxbow lakes may significantly impact the sediment-bound metal concentrations. The aim was to determine the dominating effect in the sediments' enrichment in heavy metals. Materials and methods We collected surface sediments (< 10-cm depth) from seven oxbow lakes once connected to the Tisza River (a transboundary river in Central and Eastern Europe). Four of the oxbows were located on the active floodplain, while three oxbows were at the reclaimed side (i.e., outside the flood defense levee). The sediment samples were subjected to total metal analyses (Cd, Co, Cr, Cu, Ni, Pb, and Zn) and sequential chemical extractions. Results and discussion Contamination indices (geoaccumulation index (Igeo) and pollution load index (PLI)) show a moderate but significant metal pollution of oxbow lakes situated on the active floodplain (I geo (Pb) 0.95-1.25, PLI 2.1-2.8) and an overall unpolluted to slightly polluted status of those at the reclaimed side (I geo (Pb) − 0.36-0.51, PLI 1.3-1.7). Additionally, the geochemical fractionation of the target metals showed that Cd and Zn were the most labile (Cd 29-48%, Zn 18-37% of nonresidual proportions), indicating their environmental significance. Conclusions Canonical discriminant analysis of the sediment-bound metal concentrations revealed the prevalent role of the river connection over the anthropogenic use in controlling the metal enrichment of oxbow sediments.

“…The EF normalizes the measured metal content with respect to a sample reference metal, such as Fe, Sc or Al [44]. Aluminum being one of the main elements of Earth's crust; it serves as the normalizing element to calculate EFs of PTM and metalloids element [11,44]. In the present work, aluminum was chosen as reference element for geochemical normalization.…”

“…The PERI was originally based on eight parameters, namely the levels of As, Cd, Cr, Cu, Hg, Pb, PCB and Zn [2]. However, since its postulation, a few authors have added more metals to the calculation of PERI such as Vanadium (V), Nickel (Ni), Antimony (Sb) and cobalt (Co) with the aim of making the PERI more precise when including other PTMs [11,44,49,51]. In the present work, the PCB value was excluded since it was not assessed.…”

The Valsequillo reservoir is a Ramsar wetland due to its importance as a point of convergence of migratory waterfowl. It is located in Central Mexico and is currently endangered by the constant spill of municipal and industrial discharges from Puebla city. On this context, we evaluated thirteen potential toxic metals (PTMs) in water, Water hyacinth (E. crassipes) plants and sediments at this site. A combined number of 31 samples were collected from the study area. The degree/extent of metal contamination in sediments was assessed through different geochemical indexes, namely: Geoaccumulation index (Igeo), Enrichment Factor (EF) and Potential Ecological Risk Index (PERI). The ability of Water hyacinth plants residues as a phytodepurator in the Ramsar site was tested in terms of the bioaccumulation factor (BF) and the translocation factor (TF). The results concerning sediments showed that Pb, Cu and Hg pose a threat to the aquatic environment since Igeo and EF indicate sediments ranging from moderately contaminated to contaminated. Moreover, PERI pointed out Hg as the main contributor to the ecological risk in sediments, especially in the part of the reservoir covered by E. crassipes. Water hyacinth plants displayed good capacity to absorb PTMs from the water, since the content of Co, Zn, As, Ni, Cu, Pb, Ti, Cr, Ba, Mo and V in the total plant was (all values in mg/kg of dry weight) 21 ± 9, 408 ± 300, 12 ± 6, 93 ± 21, 93 ± 69, 53 ± 29, 1067 ± 643, 78 ± 55, 362 ± 39, 14 ± 0.6 and 96 ± 35, respectively. Metal content in sediments resembles to that of E. crassipes; especially in the roots, suggesting a constant deposition of plants at the bottom of the reservoir, which contributes to the eutrophication of the water. The present work encourages the need for a sustainable management of Water hyacinth plants in the Ramsar site, since they represent a plague and a natural phyto-depurator at the same time.

Aim of the study The aim of the study was to assess the degree of heavy metal pollution in bottom sediments of lakes on the basis of geochemical and ecotoxicological indicators. Material and methods The analysis was conducted for 16 lakes located in the Gniezno Lakeland in central-western Poland. The studied lakes were included in the research program obtained from the Inspector of Environmental Protection within the framework of the State Environmental Monitoring. The Contamination Factor (CF), Pollution Load Index (PLI) and Metal Pollution Index (MPI) were calculated to assess the level of sediment contamination. Assessment of the potential toxic effects of heavy metals accumulated in bottom sediments were made on the basis of TEC, MEC and PEC values. Cluster analysis (CA) was used to show similarities between lakes in terms of heavy metal concentration in bottom sediments. To identify factors affecting metal content in bottom sediments and potential sources of pollution, the PCA analysis was applied. Results and conclusions The analyses showed a large variation of heavy metals concentration in bottom sediments. The bottom sediments of lakes were polluted mostly with lead. High concentrations of lead in individual lakes may cause harm to living organisms. The lowest concentrations of heavy metals were found in the bottom sediments of Kamienieckie Lake and the highest in Ostrówieckie Lake. Cluster analysis allowed to divide the lakes into two groups with similar concentration of heavy metal in bottom sediments. The studies did not allow to clearly expose the factors responsible for determining the heavy metal content in bottom sediments of lakes.
