The critical role of groundwater, as a critical freshwater resource, in supporting sustainable social and economic development is especially pronounced on estuarine islands with complicated aquifer formations. Employing stable isotopes and hydrochemical analyses, 19 groundwater and 4 surface water samples were collected from Chongming Island, the world's largest estuarine alluvial island, in September 2022 to identify the origin and hydrogeochemical processes involved in groundwater formation. Groundwater and surface water, both replenished by precipitation in a humid environment, reveal a stable isotopic composition indicative of enrichment from evaporation. Shallow groundwater, alongside surface water, exhibited the Ca-HCO3 water type as their primary constituent. Ionic correlation analysis, Gibbs diagrams, ionic ratios analysis, and mineral saturation index assessments demonstrate that water-rock interactions, including processes like carbonate and silicate weathering, are key factors in the evolution of groundwater chemistry; however, the influence of cation exchange reactions is comparatively weak. The Revelle index (RI) analysis revealed that seawater intrusion impacted 105% of shallow groundwater samples. Nitrate levels, measured in groundwater, demonstrated a considerable variation between 120 and 1808 milligrams per liter, with 316% of the samples exceeding the World Health Organization's standard of 50 milligrams per liter. Shallow groundwater pollution was predominantly caused by the combined effects of agricultural and industrial activities. This study's conclusions provide a scientific justification for enhancing groundwater management practices on coastal estuarine islands.

Pollution, alongside natural fluctuations in the biotic and abiotic factors of the environment, affects organisms. Several populations of Dreissena polymorpha and Dreissena rostriformis bugensis have had a battery of sub-cellular biomarkers measured in a seasonal manner. Also incorporated in the study of biomarker variability were the analyses of water physicochemistry, sediment contamination, and the internal concentrations of contaminants within soft tissues. Evaluated results displayed seasonal, inter-specific, and inter-populational inconsistencies in the measured responses, thus emphasizing the necessity of (1) acquiring long-term data on the investigated populations and (2) considering environmental factors and contaminants when interpreting biological reactions. Biomonitoring studies identified strong relationships between biomarkers, inner contaminant levels within soft tissues, and sediment contamination in *D. r. bugensis* and, to a lesser degree, in *D. polymorpha*. The complex task of individually interpreting each battery biomarker's details is simplified by a comprehensive analysis of all biomarkers, providing a signature of contamination for the sites under study.

Many developing nations face considerable challenges in securing access to quality groundwater. The El Fahs shallow aquifer, a critical water source in northeastern Tunisia, supports the region's diverse agricultural and economic sectors. The heavy reliance on this groundwater source has negatively impacted its quality. Indeed, evaluating the decline in water quality proves invaluable in crafting conservation and management strategies for water resources within this watershed. This research strives to evaluate the quality of groundwater and its suitability for irrigation, analyzing the primary chemical processes in its composition and exploring the potential origins of persistent organic pollutants (POPs). To conduct the hydrogeochemical investigation, groundwater samples are gathered and their physicochemical properties are examined. Nine groundwater stations yielded samples for the determination of polycyclic aromatic hydrocarbons (16 PAHs) and polychlorinated biphenyls (7 PCBs). Sampling operations were carried out during the month of July in the year 2020. The comparative abundance of cations was sodium (Na) exceeding magnesium (Mg), exceeding calcium (Ca), exceeding potassium (K). Correspondingly, anions showed chloride (Cl) exceeding sulfate (SO4), exceeding bicarbonate (HCO3) Groundwater displays two distinct hydrochemical facies, namely Ca-Mg-Cl/SO4 and Na-Cl. The significant presence of nitrate, exceeding pollution thresholds, was directly attributable to the intensive agricultural practices. Irrigation suitability was evaluated using various parameters, including EC, SAR, %Na, TH, PI, Mh, and Kr. To be precise, the results highlighted the unsuitability of a significant portion of the samples for irrigation purposes. The organic pollutant investigation discovered that PAH and PCB concentrations collectively exceeded the regulatory standards. To distinguish pyrolytic and petrogenic PAH sources, a substantial quantity of naphthalene and PCB28 was observed; the calculation of the low-molecular-weight (LPAH)/high-molecular-weight (HPAH) ratio followed. Based on the results, the majority of PAHs were unequivocally linked to petrogenic sources. The evaporation process, ion exchange, and water-rock interaction during groundwater flow were also found by the results to influence the chemical composition of the groundwater. The heightened pressure on groundwater quality, stemming from anthropogenic activities, has accentuated the risk of organic contamination. The presence of organic pollutants represents a rising threat to the ecological balance of our groundwater resources and human health.

In the environment, the hazardous pollutant chromium (Cr) is largely present in the forms of Cr(VI) and Cr(III). Cr(VI) exhibits greater toxicity than Cr(III) owing to its superior mobility and solubility. acute otitis media Various human activities increase chromium concentrations in agricultural soils. Consequently, plants absorb this chromium, which drastically decreases crop yields and quality by causing detrimental physiological, biochemical, and molecular changes. Harmful effects in humans are induced by biomagnification, a consequence of its infiltration through crop plants into the food chain. A causative link between Cr(VI) and human cancer has been suggested in research. multimedia learning Therefore, it is vital to implement soil remediation techniques to address chromium pollution and restrict its uptake by plants to guarantee safe food. Recent investigations into metal and metal oxide nanoparticles (NPs) have highlighted their capacity to effectively mitigate chromium accumulation and associated plant toxicity. Experimental conditions, alongside NP type, dose, exposure method, and plant species, play a role in determining the effects of these NPs. This review compiles recent research on chromium uptake and distribution, delving into the effects and potential mechanisms of metal and metal oxide nanoparticles in lessening chromium-induced stress in plants. Discussions have included the latest advancements, outstanding research gaps, and future research priorities in Cr stress reduction using nanoparticles within plant systems. The review, overall, delivers valuable insights for minimizing Cr accumulation and toxicity through the application of metal and metal oxide nanoparticles, thereby promoting safe and sustainable food production and phytostabilizing chromium-polluted soil.
