ABSTRACT Anthropogenically accelerated metal pollution of lotic systems draining mining landscapes remains a global concern due to its non‐degradability and ecotoxic nature. Nevertheless, the efficacy macrophytes as indicators remediators metal(loid) pollutants in aquatic ecosystems regions is recognised globally. However, mineral‐rich Central African Copperbelt (CACB), there limited research on effectiveness for management. Therefore, this study investigated phytopotential Typha domingensis Pers. (Typhaceae), nature‐based approach managing CACB. A total 252 samples each sediment T. were collected monthly between May 2022 April 2023 from seven streams Kansanshi sub‐catchment CACB analysed evaluate spatiotemporal variability phytoindication phytoremediation potential As, Cu, Pb Zn stream sediments. Metal(loid)s at 71% predominantly accumulated below‐ground biomass with mean concentrations 3–6 mg/kg 9–259 25–36 38–69 Zn. The BAF was above 1 As (0.8–2.6), (10.7–24.3) (1.4–4.3), indicating an accumulator these elements but excluder Cu (BAF < 1). Additionally, TF (1.5–2.0), (1.4–1.5) (1.0–2.0), macrophyte's extraction efficacy. For (TF 1), translocation characterised phytostabiliser. Similar seasonal trends also observed. response phytoindicator phytoremediator contaminants sediments should be considered management CACB's ecosystems.

“The paper cups Nile”: microplastics and other hazardous substances leached from paper cups: paper cups aquatic environmental bane in the River Nile, Egypt

Frontiers in Environmental Science, Journal Year: 2025, Volume and Issue: 13

Published: April 1, 2025

Recent studies suggest that paper cups may also contribute to environmental pollution, particularly through the release of microplastics (MPs). The Nile River, one world’s most vital water sources, faces alarming contamination levels, raising concerns about its ecological health. This study investigated whether MPs, ions, and heavy metals into assessed potential impact MPs on fish. In order completely comprehend nature scope issue, 1 L was collected from River in Assiut, Egypt were ripped tiny pieces. Paper similarly soaked similar volumes distilled tap water. Four months later, leachate each trail (three replicates for each) analyzed determine compare distribution specific microplastics. clarify availability freshwater fish, intestines two common fish species ( Oreochromis niloticus Bagrus bajad ) Assiut examined. Polyethylene, polystyrene polypropylene three main forms identified samples Nile. Also, leached same groups but lower amounts. Some take longer biodegrade water, as evidenced by absence other like rayon polyvinyl chloride any under investigation. present findings indicate a noteworthy accumulation O. B. . conclusion, these results indicated some metals, is polluted with which have negative effect aquatic organisms. brings us step closer investigating fully understanding extent problem posed their effects will ultimately be reflected human health risks.

Assessment of the Risk to Human Health and Pollution Levels Due to the Presence of Metal(loid)s in Sediments, Water, and Fishes in Urban Rivers in the State of Mato Grosso do Sul, Brazil

Urban Science, Journal Year: 2025, Volume and Issue: 9(4), P. 114 - 114

Published: April 5, 2025

This study aimed to assess the pollution levels, sources, ecological risk, and human health risks of metal(loid)s in water, sediment, muscle tissue Prochilodus lineatus Pimelodus maculatus from rivers state Mato Grosso do Sul, Brazil. The content river fish were determined by inductively coupled plasma optical emission spectrometry. Sediment assessment was carried out geo-accumulation index, contamination factor, enrichment load index. There significant differences concentration values for Al, As, Cd, Co, Cr, Cu, Mo, Ni, Pb, Hg. greater tendency elements N, Hg, Co waters Anhanduí River 2020 Cr Pb 2021. concentrations Hg are above permitted limit heavy metal ions drinking water established WHO. metals sediments set Conama/Brazil other countries. very highly contaminated Cd with moderate Pb. All showed a decline site quality, which indicates that it is polluted. Sediments classified severe Mo. Al highest P. relation analyzed. also presence such as tissues species. Therefore, these concern due consumption fish, since there carcinogenic risk related mainly As Cd.

Pollution of the Niger Delta with total petroleum hydrocarbons, heavy metals and nutrients in relation to seasonal dynamics

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Aug. 28, 2023

The African Niger Delta is among the world's most important wetlands in which ecological effects of intensive oil exploitation and global change are not well documented. We characterized seasonal dynamics pollution with total-petroleum-hydrocarbons (TPHs), heavy-metals (HMs) nutrient-loads relation to climate-driven variables. High TPH concentrations up 889 mg/L HMs 13.119 were found water samples, pronounced spatio-temporal variation throughout year. HM index contamination factor indicate serious human health hazards, especially for Cd, Cu, Hg, Ni. Significant differences TPHs/HMs observed between sites seasons, correlations TPHs-HMs, climate-variables TPHs-HMs. Nutrient levels, turbidity, salinity, temperature, SO42- high interlinked variability being greatest during wet season. These findings suggest an urgent need improved control taking into account exacerbation light climate change. Given levels contamination, further assessments exposure bioaccumulation biota should include future scenarios on humans who intensively depend system drinking water, food supply livelihood.

Lagos and Ologe Lagoons are parts of the Lagoon Complex, which provide fish as an animal protein source to locals. However, these species have a high propensity accumulate pollutants including Potentially Toxic Elements (PTEs) from their environment. This potentially constitutes health risk consumers. Therefore, this study investigated concentrations some PTEs (As, Cd, Cr, Cu, Fe, Pb, Ni, Zn) in water, sediment, (Sarotherodon melanotheron) Lagoons, ecological risks associated with consumption well likely sources PTEs.
