“…On the other hand, areas OV2 and TA2 had a greater number of REEs with high levels of enrichment, especially TA2, which showed signi cant enrichment for all REEs, with the exception of Sc, which had extreme enrichment (Sutherland, 2000). EF results above 1.5, which indicate predominantly anthropogenic origin (Mîndrescu et al, 2022;Mor et al, 2022), were evidenced for all elements in OV1, TA1, OV2, TA2 and OV3 (except Eu ), and only for Eu and Sc in TA3.…”

A artisanal mining is applied on a large scale in developing countries, and in the Amazon region, the scenario is no different. This method of mineral exploration generally does not employ mitigation techniques for potential damages and can lead to various environmental problems and risks to human health. The objectives of this study were to quantify the concentrations of Rare Earth Elements (REEs) and estimate the environmental and human health risks in artisanal mining areas for cassiterite and monazite in the Amazon region, as well as to understand the dynamics of this risk over time after exploitation. A total of 32 samples of waste classi ed as sterile and mining reject in active areas, as well as in areas deactivated for one and ten years, were collected. Soil samples were also collected in a forest area considered as a reference site. The concentrations of REEs were quanti ed using alkaline fusion and ICP-MS. The results were used to calculate pollution indices and environmental and human health risks.REEs showed higher concentrations in anthropized areas. Pollution and environmental risk levels were higher in areas deactivated for one year, with considerable contamination factors for Gd and Sm and signi cant to extreme enrichment factors for Sc. Human health risks were low in all studied areas. The results indicate that artisanal mining of cassiterite and monazite has the potential for contamination and enrichment by REEs.

“…Most researchers take into account all three pathways of exposure (ingestion, inhalation, and dermal contact) [96][97][98][99][100] when assessing the health risk; however, since inhalation has the smallest share of the risk [43,44,59], some researchers based their study only on ingestion [4,59] or ingestion and dermal contact [9,10,44,[101][102][103]. Several terms are used to define the chronic intake of HMs, such as the chronic daily intake (CDI) [47,66,70,76,98,104,105], the average daily intake (ADI) [36,40,73,93,106], and the most commonly used the average daily dose (ADD) [5,37,52,67,[107][108][109]. Less frequently used indices are D [39,43], daily intake of metals (DIM) [80], and Exp [101].…”

Heavy metal(loid)s (HMs) play an important role in economic development since they are used in various branches of industry. However, all industrial activities emit HMs into the environment, where they are no longer useful but potentially toxic. It has been observed that HMs enter the soil and sediment, and potential human health risk may arise due to their excessive accumulation. Having in mind the importance of assessing the risk due to HMs in these media, we analyzed published works in the last decade and created a summary of exposure factors in health risk models for HMs in soil and sediment. This analysis revealed a remarkable increase in the number of publications about health risk assessment of HMs, especially in the last few years. Since many differences in the values of the exposure factors and their distributions were noted, this study focused on elucidating these differences. Non-carcinogenic and carcinogenic health risk assessment models were evaluated through a deterministic approach that is prevalent in use, and a probabilistic one, which is gaining more and more attention in research. In the end, guided by the studied literature, we propose the values and distributions for the exposure factors.

“…Saha explored different types of GIS spatial interpolation methods, and the final results show that the inverse distance weighting method (IDW) is the optimal interpolation model for studying the spatial distribution pattern of toxic metal content (Saha et al, 2022). Sediment quality guidelines (SQG), pollution load index (PLI), and human health risk assessment have been widely applied to metal ion hazard assessment in various regions (Kolawole et al, 2022;Lim et al, 2022;Mor et al, 2022;Tnoumi et al, 2022;Zhang et al, 2022a). Xu studied the Hulan River Basin and found that Cd has caused serious biological risk in estuarine areas.…”

Metal pollution of river sediments in industrial areas has attracted widespread attention. In this study, 11 metal ions (including Fe, Al, Mn, Ag, Cd, Cr, As, Cu, Pb, Zn, and Ni) were determined and analyzed in river sediments of typical industrial areas in the Kuye River Basin, a first-level tributary of the Yellow River. The geological accumulation index, enrichment factor, and pollution load index indicated that the metal ions in this area were enriched and polluted to different degrees. The spatial distribution of the 8 kinds of heavy metals showed that the content in the upstream and downstream was higher, and the middle reaches were lower. The heavy metals mainly came from local industrial activities, coal mining and transportation, and soil weathering, Human activities were the main reasons for the dramatic spatial changes and high levels of heavy metals. Mass inventories of metal ions in sediments should not be ignored. The results of the combined potential ecological risk index and sediment quality guidelines showed that the ecological risk downstream of the area was high, and Ni and Pb have caused adverse biological reactions. The human carcinogenic risk assessment result showed that the non-carcinogenic hazard quotient of metal ions in the study area was at an acceptable level, but the carcinogenic risk level of Ni and Cr was higher than 10− 4, which was an unacceptable level and must be got enough recognition. The results of this study can provide theoretical support for the pollution control and environmental restoration of rivers in energy-enriched areas.
