“…5b). Some researchers reported that if EF values exceed 1.5 enrichment is the most probable origin of anthropogenic activities (Ravisankar et al, 2015;Tepe et al, 2022;Topaldemir et al, 2022). However, in this study, EF values greater than 2 for Nickel do not suggest an anthropogenic source, because the study region is not an industrial area, but an area with rural and agricultural activities.…”

This study describes the role of grain size in controlling the pollution levels in clastic sedimentary rocks, by presenting results from the Eocene sequence in NE Türkiye. The mean concentrations of the potentially toxic elements (PTEs) declined in order of Ni(179) > Zn(89.6) > Cu (62.5 ) > Cr(24.6) > As(15.9 ) > Pb(13.8) > Cd(0.21) > Hg(0.11) in the shale/marl and Ni(113) > Zn(48.2) > Cu(22.3) > Cr(21.7) > As(10.8) > Pb (7.4) > Hg(0.09) > Cd (< 0.1) the in sandstone. Among the PTEs, Ni, Cu, As, Cd, and Hg in the shale/marls, and Ni, As, and Hg in the sandstones were enriched to the upper continental crust. Based on the values of the enrichment factor shales/marls were “minor enrichment” – “very severe enrichment” with As and “moderate enrichment” – “moderately severe enrichment” with Ni, and the sandstones were “moderate enrichment” – “very severe enrichment” with As and “moderate enrichment – “moderately severe enrichment” with Ni, respectively. The potential ecological risk index indicated that the PTEs in the shale/marl samples have a moderate to considerable potential ecological risk and the sandstone samples pose a low to moderate potential ecological risk. In a shale sample, the hazard quotienting, and hazard index values of the As were found to be greater than 1 for children. The carcinogenic risk indexing values of the As in the samples are higher than the acceptable level of risk for children. The multivariate statistical analysis summarized that PTEs accumulation in the Eocene sedimentary sequence was related to anthropogenic, hydrothermal fluid, and lithological influence.

“…Similar to the previous studies performed in the Giresun rivers, Al and Fe were found to be the most dominant metals in the Ordu river sediment and water samples. Furthermore, the spatial-temporal pollution indices and distribution of heavy metals in Ordu at the Turnasuyu stream sediment were assessed systematically by considering seasonal samples from various sites . As expected, average concentrations of 15 080 and 6416 mg/kg were observed for Fe and Al elements, respectively.…”

Identifying Geogenic and Anthropogenic Aluminum Pollution on Different Spatial Distributions and Removal of Natural Waters and Soil in Çanakkale, Turkey

The Çanakkale–Kirazlı region (Turkey) is enriched with minerals, especially aluminum (Al), which dangerously get transported into aquatic media due to several mining and geological activities in recent years. In this study, Al and other potentially toxic metals (PTMs) including B, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Si, and Zn, in both water and soil samples, were measured for quality determination. Selected metals were also analyzed by the enrichment factor (EF), the geoaccumulation index (I geo), the contamination factor (CF), and the pollution load index (PLI) to evaluate both water and soil pollution geogenically or anthropogenically. Also, the metals were clustered to support the pollution source with Pearson’s correlation, principal component analysis (PCA), and hierarchical cluster analysis (HCA). Forty-five natural water samples and 12 soil samples were collected spatially. To perform pollution assessment, two fundamental treatment processes to remove Al pollution from the sample including the highest Al concentration (38.38 mg/L) in water were applied: (1) precipitation with pH adjustment and (2) removal with ion exchange. The pH values of water samples were changed in the range of 3–9 to test the dissolution of Al. The results demonstrated that the study area was mostly under the influence of geogenic aluminum pollution.

“…The EFc values greater than 1.5 suggest that human activity was most likely the cause of enrichment. Conversely, metals with an EFc of 0.05–1.50 are considered lithogenic [ 63 ]. [ 63 ].…”
