Assessing the impacts of river bed mining on aquatic ecosystems: A critical review of effects on water quality and biodiversity

HydroResearch, Год журнала: 2024, Номер 7, С. 122 - 130

Опубликована: Янв. 1, 2024

River bed mining, an activity crucial for meeting the demands of construction and infrastructure development, has raised concerns about its potential adverse impacts on aquatic ecosystems. This critical review explores multifaceted consequences river mining water quality biodiversity, aiming to provide a comprehensive understanding ecological implications. The methodology consisted searching through number different scientific databases in order locate works that had been subjected peer published between years 1985 2023 subject matter this study. Among keywords controlled vocabulary were incorporated into search strategy ecosystem, quality, remedial measures. degradation emerges as primary concern associated with mining. Sediment release, altered flow patterns, increased turbidity are identified key contributors deterioration. These changes have cascading effects physicochemical parameters environment, influencing nutrient cycles, dissolved oxygen levels, overall ecosystem health. Biodiversity, fundamental component ecosystems, faces spectrum challenges due alteration riverbed habitats disruption natural dynamics pose direct threats survival various species. Additionally, sedimentation resulting from activities can smother affect reproductive success sensitive organisms, further exacerbating biodiversity loss. role sustainable practices, habitat restoration, implementation buffer zones is evaluated context preserving supporting conservation. provides nuanced analysis emphasizing importance holistic approach address findings underscore urgency adopting practices robust regulatory measures ensure long-term health resilience riverine environments face ongoing development pressures.

Electrochemical Sensors based on Gold–Silver Core–Shell Nanoparticles Combined with a Graphene/PEDOT:PSS Composite Modified Glassy Carbon Electrode for Paraoxon-ethyl Detection

ACS Omega, Год журнала: 2024, Номер 9(2), С. 2896 - 2910

Опубликована: Янв. 2, 2024

Herein, a nonenzymatic detection of paraoxon-ethyl was developed by modifying glassy carbon electrode (GCE) with gold–silver core–shell (Au–Ag) nanoparticles combined the composite graphene poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS). These were synthesized using seed-growth method and characterized UV–vis spectroscopy high-resolution transmission electron microscopy (HR-TEM) techniques. Meanwhile, structural properties, surface morphology topography, electrochemical characterization Au–Ag core–shell/graphene/PEDOT:PSS analyzed infrared spectroscopy, field emission scanning (FE-SEM), atomic force (AFM), impedance (EIS) Moreover, proposed sensor for based on modified GCE demonstrates good electroanalytical performance when investigated cyclic voltammetry (CV), differential pulse (DPV), chronoamperometry It found that synergistic effect between graphene/PEDOT:PSS provides higher conductivity enhanced electrocatalytic activity at an optimum pH 7. At 7, shows linear range concentrations from 0.2 to 100 μM limit 10 nM high sensitivity 3.24 μA μM–1 cm–2. In addition, confirmed reproducibility, possibility being further as disposable electrode. This also displayed selectivity in presence several interfering species such diazinon, carbaryl, ascorbic acid, glucose, nitrite, sodium bicarbonate, magnesium sulfate. For practical applications, this employed determination real samples (fruits vegetables) showed no significant difference standard spectrophotometric technique. conclusion, might have potential be platform sensors pesticide detection.

Risk assessment of heavy metals in the major surface water system of Nepal with potential remediation technologies

Environmental Challenges, Год журнала: 2024, Номер 14, С. 100865 - 100865

Опубликована: Янв. 1, 2024

This paper presents an analytical risk assessment of heavy metals (HMs) in twenty-three rivers and two typical lakes across five different provinces Nepal. The study examines their effects on humans varying age groups ecological systems using indexes such as Hazard Index (HI), Cancer (CI), hazard quotient (HQ). human health reveals that female children are the most vulnerable to metal risks, followed by male children, adults, adults. Notably, Co, Pb, Cd, As, Cr, Cu present substantially high non-carcinogenic risks for all adults with HI values ranging from 1 more than 100. However, this is confined only (both female) Mn Ni. HMs Ni, Pb have a very carcinogenic some (CI > 1.00E-3). Concerning risk, HQ found be significantly above permissible limit order Cu>Cd>Pb>Fe>Zn>Co>Ni>Mn. Furthermore, integration various treatment technologies would enhance effectiveness eliminating polluted river water, ensuring water becomes suitable irrigation other purposes. identified priority controlling factors potential remediation can provide valuable insights policymakers making informed decisions concerning safety system.
