Hence, this study was conducted to address the existing research gap by evaluating heavy metal contamination and its associated risk assessment in surface water bodies, in Mohammedia prefecture, Morocco. A total of 22 water samples were evaluated regarding physicochemical factors and heavy metals. The parameters analyzed are pH, temperature (T), electrical conductivity (EC), total dissolved solids (TDS), calcium (Ca²⁺), Sodium (Na⁺), Potassium (K⁺), Ammonia (NH⁺), dissolved oxygen (DO), Sulphate (SO₄²⁻), nitrite (NO²⁻), nitrate (NO³⁻), phosphate (PO₄³⁻), total phosphate (TP), total kjeldahl nitrogen (TKN), cadmium (Cd), copper (Cu), Iron (Fe), lead (Pb), and zinc (Zn). Overall water quality (Ow) and status of contamination presented the water quality and pollution quantitatively. Carcinogenic and noncarcinogenic risks were estimated for health risk assessment. Ca²⁺ was the most abundant cation, and SO₄³⁻ was the most abundant anion. Heavy metal concentrations were within permissible limits. Ow was good in terms of being suitable for parameters, i.e., &lt;1 except for NH+. Which indicated water quality in the category of “highly polluted” &gt;2.5. Pollution index (PI) indicated high pollution (14–74) at S3, S4, S5, and S6 sample points. In addition, Pb was a significant contributor to deteriorating water quality, with individual contributions ranging from 1 to 12 at sites S1, S2, and S3. For heavy metal hazards, i.e., adverse health effects, Hazard Quotient (HQ) (0.0002–0.01) was &lt;1 for sample points, and Hazard Index (HI) (0.007–0.01) had a similar trend. They were inferring no significant non-carcinogenic health impact on its consumers. Carcinogenic risk (CR) was found to be within acceptable limits for CD, Cu, Pb, and Zn, i.e., 10⁻⁴ to 10⁻⁶.

It focuses on MXene-mediated degradation pathways, especially photocatalytic and electrocatalytic mechanisms, considering their redox potential and light-harvesting capabilities. Additionally, the adsorption dynamics of MXene-based adsorbents are scrutinized, covering adsorption capacity, kinetics, and regeneration/recyclability. The review offers a comparative evaluation of MXenes with other 2D materials, positioning MXenes within the broader context of toxin management solutions. This article stands out for its novel and comprehensive approach, being the first to concurrently address the detection, degradation, and removal of environmental toxins using MXenes. The review concludes by underscoring the vast potential of MXenes in addressing environmental toxins. It emphasizes the urgent need for continued research to optimize their performance, scale up production, and enable practical implementation. This detailed reference aims to serve researchers and practitioners in environmental management, guiding future innovations and applications of MXenes in toxin control.</p></div>","PeriodicalId":100480,"journal":{"name":"Environmental Chemistry and Ecotoxicology","volume":"6 ","pages":"Pages 390-407"},"PeriodicalIF":9.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590182624000353/pdfft?md5=9bc26f736be11514cb54556eeff8e338&pid=1-s2.0-S2590182624000353-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142129152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
