the concentrations and sources of heavy metals in shallow sediments in Lake Bafa were investigated. the concentrations of nine heavy metals and the total organic carbon content in sediment samples were determined for between Summer 2015 and Spring 2016. The mean contents of heavy metals were in decreasing order fe > Mn > ni > cr > Zn > cu > co > pb > cd. Sediment quality guidelines indicate that Cr, Cu, and Ni pose a considerable threat to the aquatic ecosystem in Lake Bafa. Site L3 was found to be contaminated with cd, cr, and ni, and the pollution load indices suggest that these metals had anthropogenic sources. the sediment samples were notably enriched with cd and ni. there is no consistent trend for seasonal effect in terms of the sample locations. However, at all sampling points, an increase in heavy metal concentrations was observed in the autumn. the results of a multivariate analysis indicate that the sources of co, cu, fe, Mn, pb, and Zn were all natural, the sources of cd were anthropogenic, and the sources of ni and cr were both anthropogenic and natural. these results highlight that cd, cr, and particularly ni represent the most serious threat in terms of heavy metal pollution in the ecosystem of the lake. Heavy metals mainly enter aquatic environments as a result of a variety of human activities (e.g., agriculture, combustion, corroded underground pipes, industrial plants, sewage, smelting, and vehicles) 1-3. Exposure to heavy metals has been linked to various negative health effects, including cancer, behavioural problems, impaired intelligence, developmental problems, kidney damage, and miscarriage or stillbirth 4. Heavy metals are not readily degraded in the environment, and those that enter a water body can remain there for some time. They are usually found in low concentrations in aquatic systems 5 , and high concentrations of heavy metals in sediments can indicate anthropogenic rather than natural sources 6,7. Heavy metals are poorly soluble in water, so predominantly sorb to suspended particles that then settle as sediment 8. Heavy metals can thus enter the food chain in the aquatic environment, and become available for accumulation in biota 9. Fish, which are at the top of the food chain and are an important food source for humans, can accumulate heavy metals in their tissues 10 , and this characteristic makes them an effective indicator of pollution 11. Accordingly, assessment of pollution from heavy metals in sediments in the environment is very important in terms of its effects on aquatic organisms and human health 12. Lake sediments are a sink for heavy metals 13,14 , and heavy metal concentrations are generally higher in sediment than in water 15. Indeed, concentrations of heavy metals in water are sometimes lower than detection limits, meaning that sediment should be analysed to assess levels of contamination by heavy metals in the aquatic system 16-18. Lake sediments mostly act as a sink for heavy metals; on the other hand, they can also act as a source to the overlying water 19,20. C...

“…The most crucial place in this area is the Upper Silesian Industrial Region (in Polish: Górnośląski Okręg Przemysłowy; GOP). This is the largest industrial area in the country and one of the biggest in Europe, a so-called key anthropogenic “hot spot” area [ 3 , 4 , 5 ]. In 2018, in the Silesian Voivodeship there were 201 municipal WWTPs in operation, among which 109 were biological and 91 with increased biogene removal.…”

“…The most commonly used indices are ER, RI and RAC [ 2 , 9 , 31 , 32 ], while ICF and GRI are rarely applied [ 2 , 33 ]. The above-listed indices (except for IER and GER) were also used to assess the ecological risk in other environmental samples, like soils and sediments [ 5 , 30 , 34 ]. So far, there have been only a few studies regarding the identification of the chemical forms of heavy metals in sewage sludge at different stages of its processing [ 2 , 4 , 35 ].…”

The present study aimed to demonstrate that identification of the chemical forms of heavy metals in sewage sludge produced in municipal Wastewater Treatment Plants (WWTPs) is a critical element of ecological risk assessment, especially in terms of its agricultural or natural use. The concentrations of seven heavy metals (Cd, Cr, Cu, Ni, Pb, Zn and Hg) were determined using inductively coupled plasma optical spectrometry (ICP-OES) and cold vapor atomic absorption spectrometry (CV-AAS). The chemical forms of heavy metals were analyzed in accordance with the sequential extraction method proposed by the Community Bureau of Reference (BCR). Sludge samples were collected at the five municipal WWTPs located in the largest industrial area in the country, i.e., the Upper Silesian Industrial Region (southern Poland, central Europe). The ecological risk was assessed by calculating the Potential Ecological Risk Factor (ER), Risk Index (RI), Risk Assessment Code (RAC), Individual Contamination Factor (ICF), Global Risk Index (GRI) as well as the author’s indices, i.e., Individual Ecological Risk (IER) and Global Ecological Risk (GER). To demonstrate the differences between the level of ecological risk posed by the different heavy metals, sludge samples were collected at two specific points of the processing line. Considering the chemical forms of heavy metals, the highest ecological risk was posed by Zn, Cd and Ni, while in the case of their total concentrations, by Cd and Hg. The obtained results confirm that quantitative determination of the total content of heavy metals in sewage sludge is not a sufficient criterion in assessment of the ecological risk that these elements pose to the natural environment and living organisms. Moreover, multivariate statistical analysis revealed a significant correlation between the concentrations of heavy metals, which indicates that they plausibly originate from the same source of pollution.

“…The sedimentological approach is commonly used in ecological risk assessment of the aquatic environment [7][8][9]. However, one of its limitations is the absence of background concentrations due to lack of pristine (preindustrial) sediment environments devoid of anthropogenic contamination in most settings.…”

“…However, one of its limitations is the absence of background concentrations due to lack of pristine (preindustrial) sediment environments devoid of anthropogenic contamination in most settings. Thus PTEs in shale and the earth's crust are used as background values [9]. The current study used the widely applied average shale concentrations as background values [7,10].…”

Limited information is available on trace element-water contamination and health risk assessment of small-scale intensive fish farming in low-income settings. Such information creates awareness among fish consumers, policy makers and the scientific community, regarding dietary exposure and health risks for not well-reported settings. The concentrations of potentially toxic trace elements in water, sediment and fish (T. rendalli, O. nitloticus and M. salmoides) were determined by spectrometry. The ecological and potential human health risks were assessed for Magobo dam, NE Zimbabwe, using the Hakanson ecological approach and the United States Environmental Protection Agency risk-assessment model, respectively. Concentrations in water and sediment appeared to increase in the order: cadmium < arsenic < lead. They restricted water use for irrigation and human consumption. The potential ecological risk factors for individual trace elements were below the index range for low risk. The potential ecological risk index for the dam (7.20) did not constitute ecological risk. The concentrations of trace elements in fish significantly varied with species, length and tissue (p < 0.05). The concentrations of arsenic and lead in gills, liver and muscle for O. niloticus and arsenic in M. salmoides were greater than international maximum permissible limits for fish. The target cancer risk due to dietary exposure to arsenic in the three fish species was in the range 10-6. There is no obvious cancer risk to the exposed population.
