“…In recent years, there has been considerable interest in the impacts of human-induced trace metal pollution in the water and sediment quality of the largest rivers in the world (Benet, 2019;Zhou et al, 2020) such as the Amazon (Telxeira et al, 2018), Brahmaputra (Saikia et al, 2016), Yamuna (Pandey et al, 2011), Ganga (Paul, 2017), Lerna (Mendoza et al, 2018), Niger (Izah et al, 2017), Nile (Lasheen and Ammar, 2009;El Bouraie et al, 2010;Satar et al, 2017), Danube (Rusina et al, 2019;Belis et al, 2019;Abonyi et al, 2019) and Po (Farkas et al, 2007). In Turkey, densely populated cities have also been established along the 8333 km-long coastline, especially alongside rivers and on delta plains where overpopulation leads to the same environmental risks (Gazioğlu, 2018).…”

Metals have come to the fore among the pollutants monitored in aquatic ecosystems in recent years. Fresh waters especially constitute a "hot spot" due to their limited reserves. In order to analyze the sources of metal-induced pollution, ecological risk level and pollutants of the Sarıçay River passing through the city of Çanakkale, sediment samples were collected from 26 stations and element analyses were carried out in ICP-MS. Anthropogenic effects and the risks they cause were determined by calculating the enrichment factor, geoaccumulation index, and potential ecological risk from the obtained data. Anthropogenic enrichment was detected for Cr, Ni, Pb, Au, Ag and Ba, Bi, Tl, Na, Zn, Mg, K, As, Sb, and Mn with the largest amount being Cd. The level of enrichment varies from moderate to very high. According to the results of risk analysis, a moderate risk for Cd was determined and a very high risk for Ni and Pb. Agricultural activities, atmospheric deposition and mineral deposits in the basin were identified as the major sources from the multivariate statistical analysis performed to determine the main sources of metal inflows.

“…It is important to mention that, in contrast to industrial mining that is committed to standard working procedures and for recovering mined areas, Au mining activity can also occur in an artisanal form, using rudimentary and less efficient extraction methods (Pereira et al, 2020;Teixeira et al, 2018Teixeira et al, , 2021. In addition, little or no environmental control measures are often implemented, which can make artisanal mining extremely harmful to the environment and pose a risk to the health of people influenced by these activities.…”

“…Soil contamination by potentially toxic elements (PTE) is a concern in mining areas, especially in Au exploration sites that are commonly enriched with elements such as As, Cd, and Hg (Teixeira et al, 2018, 2021; Xiao et al, 2017). Depending on the concentrations, these elements can threaten the ecosystem and human health, causing ecological risks and diseases such as cancer (Sharafi et al, 2023), which indicates the need for practices to mitigate the dispersion of PTE in the environment.…”

Monitoring key soil and vegetation attributes in mining areas under environmental rehabilitation is essential to ensure that the intervention techniques are effective. There are several approaches to monitoring mining areas and their integration is necessary to process large amounts of information. Thus, this study aimed to (i) assess soil multi‐contamination with potentially toxic elements (PTE) and human health risks; (ii) obtain a soil quality index with soil fertility data; (iii) calculate spectral index; (iv) show rehabilitation status based on vegetation attributes, and (v) compile these indices in a single measure. Four tailings' ponds (TPs), two waste piles (WPs), and an area of native forest from a gold mine in the Carajás National Forest were evaluated. Soil quality and vegetation cover are good in forest areas, with no evidence of PTE contamination. On the other hand, the TPs have poor fertility and vegetation cover, as well as higher levels of PTE. Human health risk indices obtained for all PTE were lower than 1, indicating a low risk to human health. The results of integrating the different indices suggest that the environmental conditions of the WPs are better than those of the TPs, which are still far from the environmental conditions of native areas. Soil attributes and vegetation development in TPs areas could be enhanced by the incorporation of organic materials and fertilizers and by planting species with phytoremediation potential. Finally, the integrative approach of the different indices proved to be useful in assessing the rehabilitation progress of the areas.
