“… 25 : where is the ratio of the concentration of a particular metal i (C i ) to the Al concentration (C Al ) in the sediment sample; and is the ratio of the background concentration of a particular metal i (C i ) to the reference background concentration of Al (C Al ). Either Al or Fe has been used as a conservative element for EF calculations in many studies to distinguish the source of heavy metals 26 , 27 . In this study, Al was selected as a reference metal.…”

Dongting Lake is one of the most important inland freshwater lakes in China. To investigate the spatial distribution and seasonal variation characteristics of heavy metals (Cr, Co, Cu, Zn, Cd, and Pb) in the lake, 53 surface sediment samples were collected in the East Dongting Lake (ED Lake) in the wet and dry seasons. Results show Cr, Co, Cu, Zn, Cd, and Pb contents were 1.7 (1.9), 1.8 (2.0), 2.9 (3.0), 1.9 (1.9), 11.7 (13.1), and 2.0 (2.2)-fold of their geochemical soil background values of Hunan province (China) in the wet (dry) season. Spatial and seasonal heterogeneity could be found in the distribution of Cr, Co, Cu, Zn, and Pb in the surface sediments. The enrichment factor (EF) suggested that Cd has reached severe enrichment in the sediment. The result of the geo-accumulation index ($${I}_{geo}$$ I geo ) indicated that Cr, Co, Cu, Zn, and Pb were at levels corresponding to low contamination, and moderately to highly polluted with Cd. Multivariate statistical analysis including pearson correlation analysis and principal component analysis was used for the identification of potential sources of the heavy metals in the sediments. The results showed that Cu, Zn, and Pb from the sediments of the East Dongting Lake in the wet and dry seasons were possibly anthropogenic sources, such as emissions from mining and smelting while Al, Fe, and Cr are attributed for natural sources. Cd enrichment in the sediments is influenced by both natural factors, and human activities in local areas.

“…Results indicated that the investigated samples were moderately contaminated with Ag, Cr and As, moderately to severely contaminated with Zn and Ni, and severely contaminated with Cu. 30 Our previous study conducted between 2011-2012, a study on marine pollution in the region identified Pb, As, and Cu levels above those permitted by the Turkish Food Codex in shrimp sample collected from the coasts of Tekirdağ 31 .In addition, another research is to determine the mercury, lead and cadmium accumulation in scads (Trachurustrachurus) caught in the near Tekirdag in the sea of Marmara in 1996. Fish sample average mercury contents were 0.029 ppm and average lead contents were 0.038 respectively.…”

Objective: The aim of this report is to evaluate the heavy metal pollution of the Ergene Basin and its effects on public health. Methods: Local people, as well as the surrounding ecosystem, are exposed to varying levels of chemical substances. Those working in different industrial sectors are particularly vulnerable. Ergene river, one of the most important water sources in the Thrace region, is being rapidly polluted due to increasing industrialization and urbanization in the region. Many chemicals are discharged into the Ergene river without proper treatment. This is largely due to the inadequacy of residential and industrial treatment plants, as well as the proliferation of illegal dumping in the region. Thus, both the environment and the people face a serious threat. For many years there have been many studies investigating the presence and effects of heavy metals on the water, soil, air, plants, animals and people of the region. In our study, the literature on heavy metal concentrations in the region was summarized and the five-year cancer statistics were evaluated. Results: The lead concentration, which is a common metal in all the different environmental compartments, has been found to be above the maximum limit value. Furthermore, the evaluation of cancer data showed an increase in all cancer types between 2006 and 2011. Conclusion: Although it is difficult to relate cancer and environmental factors directly, studies show that there may be a close relationship between lead concentration (largely produced by the textile and leather industries) and the occurrence of bladder and kidney cancers. However further research, such as risk assessments, is required to establish more definitive conclusions.

“…Heavy metals are characterized by low water solubility, which facilitates sedimentation and accumulation in river sediments. The migration of heavy metals in a river system mainly depends on sediments, particularly their organic matter content and granulometric composition [15,16]. The presence and concentration of heavy metals in river sediments are linked to the influence of diverse pollution sources and the geological structure and climatic conditions affecting the natural erosional processes of parent rocks.…”

“…Moreover, the chemical composition of sediments often serves as a more reliable indicator of water contamination than the chemical composition of water, which exhibits more significant temporal variability [1]. At the same time, sediments' role in assessing the aquatic environment's state is becoming increasingly important, as the direct relationship between the quality of river sediments and the state of water contamination is undeniable [9,13,16,21,22].…”

Heavy metals play a crucial role in the environment due to their toxicity, persistence, and bioaccumulation ability, which can lead to severe ecological and health risks. This study aimed to investigate the impact of urbanization and agricultural practices on the heavy metal content in the sediments of the Bug River catchment. To this end, 96 surface sediment samples were collected from various points in the Bug River catchment, including from urban, agricultural, and forested areas. The samples for laboratory analysis were collected in July 2018, 2019, and 2020 in the Polish part of the Bug River watershed. Heavy metal (Zn, Pb, Cr, Ni, Cu, Fe, Mn, and Cd) concentrations were determined using atomic absorption spectroscopy (AAS). The geoaccumulation index (Igeo), contamination factor (CF), and pollution load index (PLI) were used to assess the degree of sediment contamination. The results indicate higher concentrations of heavy metals in urban sediments, where cadmium concentrations reached up to 2.5 mg/kg, compared to agricultural and forested areas, where concentrations were significantly lower. The average Igeo value for cadmium was 0.24 in agricultural areas and 0.15 in urban areas, suggesting the predominance of anthropogenic influences over natural sources. The highest PLI values were found in urban areas, reaching a maximum of 0.33, indicating higher pollution levels. Statistical analysis revealed that urban emissions and agricultural activities significantly influenced the presence of these metals in the Bug River sediments. This study’s conclusions emphasize that effective river water quality management requires continuous monitoring and an understanding of anthropogenic and natural pollution sources. The results contribute to a better understanding the interactions between human activities and water quality, crucial for planning protection and remediation strategies. Additionally, this study provides critical insights into optimizing pollution management strategies and developing remediation methods, serving local and regional policymakers in planning protective actions.
