“…The fluctuating health risk values across different months in NURB highlight distinct water flow process and hydrochemical dynamic conditions between surface and underground water flow fields. Similar phenomenon has been observed in Tebessa, Algeria (Bilal et al 2021). Except for July, the maximum health risk values for adults and children exposed to metal elements in the water through drinking were consistently higher than 5.0×10 −5 a −1 throughout the other months.…”

To investigate the presence of metal elements and assess their health risk for the populace in the Nandong Underground River Basin (NURB), we conducted an analysis of eleven common heavy metals in the water body. A Health risk assessment (HRA) model was employed to analyze 84 water samples from the NURB. The detection results revealed the following order of heavy metals concentrations: Fe > Al > Mn > Zn > As > Cd > Pb > Cr > Ni > Cu > Hg. Correlation analysis indicated a certain similarity in material source and migration transformation among these eleven metal elements. Our study identified that the health risks for local residents exposed to metal elements in the water of NURB primarily stem from carcinogenic risk (10 −6 -10 −4 a −1 ) through the drinking water pathway. Moreover, the health risk of heavy metal exposure for children through drinking water was notably higher than for adults. The maximum health risks of Cr in both underground and surface water exceeded the recommendation standard (5.0×10 −5 a −1 ) from ICRP, surpassing the values recommended by the Swedish Environmental Protection Agency, the Dutch Ministry of Construction and Environment and the British Royal Society (5.0×10 −6 a −1 ). The results of the health risk assessment indicate that Cr in the water of NURB is the primary source of carcinogenic risk for local residents, followed by Cd and As. Consequently, it is imperative to control these three carcinogenic metals when the water was used as drinking water resource.

“…In addition, they found that the children's average HI values were higher than those for adults. Our previous study on groundwater and surface and spring water in an area affected by a phosphate mine [6] showed higher average HIs among children, almost twice as high as those among adults, indicating that children are more susceptible to non-carcinogenic health effects. However, these researchers found that the non-carcinogenic risks due to PTMs resulted in HI values of less than 1 (HI < 1).…”

“…This is due to the fact that Cd is one of the main emissions from phosphate mining activities [83]. In addition, our earlier study in the vicinity of the phosphate mine area, including wells and surface and spring water, showed that Cd and U were among the main contaminants, exceeding the international standards for PTMs [6]. On the other hand, the individual E i r values of the other toxic metals were less than 40, indicating a low potential risk.…”

“…They are characterized by extensive sources, non-degradable properties, and cumulative behaviors, which are mainly dependent on their speciation and persistence in the environment [1][2][3]. During recent decades, research on PTMs has focused on understanding their spatial distribution and extent and the identification of different sources of contamination [2,[4][5][6].…”

Environmental Geochemistry of Potentially Toxic Metals in Phosphate Rocks, Products, and Their Wastes in the Algerian Phosphate Mining Area (Tébessa, NE Algeria)

This study is focused on the environmental geochemistry of potentially toxic metals (PTMs)-bearing products and wastes in a mining area in Djebel Onk (NE Algeria) and their potential ecological and health risk assessment. Representative samples from (i) commercial products and (ii) grain size classes of wastes were mineralogically characterized using X-ray diffraction. The major and PTMs elements in the samples were chemically analyzed via ICP-AES and ICP-MS, respectively. The results reveal that the samples were mostly composed of carbonate fluorapatite (P2O5 > 24 wt %) and yielded PTM concentrations within the average range of phosphorites in neighboring countries and worldwide deposits as well. The concentrations of V, Cd, As, Ni, and Pb in the products were found to be within the acceptable values according to various standards, such as the Canadian and German Fertilizer Ordinance policies. Geochemically, PTMs distribution is linked to the main sub-composition of phosphate rock (apatite, clay, and dolomite). The Enrichment Factors (EF) display very-high-to-extremely-high enrichment of PTMs (Cr, Zn, As, Sr, Mo, Cd, Sb, Tl, Th, and U), while V, Co, Cu, Ni, Zr, Ga, Nb, and Pb show minor and moderate-to-high enrichments. Among all the PTMs, Cd, Tl, and U display a very high ecological risk (PERI) and contribute most to the total risk index (RI). The human health risk assessment of PTMs represented by the Hazard Index (HI) indicates that the non-carcinogenic risks are below the threshold values (HI < 1), while the HI values are higher for children than they are for adults. However, the cancer index (life time cancer risk) for Cr, Ni, As, and Cd for children and Cd for adults is greater than the acceptable threshold. These results are useful for phosphate beneficiation via removing these PTMs from the commercial product for efficient waste management.

“…Furthermore, heavy metals are the most commonly found contaminants in wastewater that are a public-health concern due to their high toxicity [ 10 ]. Sources of heavy-metal pollution include mining waste [ 11 , 12 ], water leaks in landfills [ 13 ], municipal wastewater, and industrial wastewater [ 14 ], especially from industries, such as electroplating and electronic metal fabrication [ 15 ]. Heavy metals are necessary for human metabolism; however, high concentrations can be toxic and dangerous to humans [ 16 , 17 ].…”

A Critical Review of Snail Shell Material Modification for Applications in Wastewater Treatment

2023

Sea material is becoming increasingly popular and widely used as an adsorbent in wastewater treatment. Snail shell, a low-cost and natural animal waste material, has been shown to have a high calcium content (>99%) and a large potential surface area for the development of sustainable adsorbents. This paper presents a novel synthesis of methods for using snail shell absorbent materials in the treatment of wastewater containing heavy metals, textile dyes, and other organic substances. Modified biochar made from snail shells has gained popularity in recent years due to its numerous benefits. This paper discusses and analyzes modification methods, including impregnating with supplements, combining other adsorbents, synthesis of hydroxyapatite, co-precipitation, and the sol–gel method. The analysis of factors influencing adsorption efficiency revealed that pH, contact time, temperature, initial concentration, and adsorbent dose all have a significant impact on the adsorption process. Future research directions are also discussed in this paper as a result of presenting challenges for current snail adsorbents.
