The aquatic ecosystem elemental for global biodiversity and human sustenance confronts enduring threats from pollutants, notably pesticides. Metalaxyl, a prevalent agrochemical has garnered attention due to its extensive application and potential endocrine-disrupting characteristics. This study has utilized an untargeted metabolomics approach employing UHPLC-Q-Orbitrap MS, to evaluate the metabolic changes associated with chronic experimental exposure (60 days) to Metalaxyl at an environmentally relevant concentration (25 ng/g) using Wistar albino rats. The results demonstrated notable variations in phosphatidylethanolamines, amino acid profiles, and vitamins, suggesting them as potential biomarkers to elucidate the influence of this environmental contaminant on biological systems. Furthermore, the pathway analysis revealed significant alterations in steroid biosynthesis, citric acid (TCA) cycle, Phenylalanine, tyrosine, and tryptophan biosynthesis, purine, and pyrimidine metabolisms. These results on the health implications of Metalaxyl offer valuable insights into its ecotoxicological effects and associated health risks. They also uncover these contaminants' profound and far-reaching impact on biological pathways by providing invaluable insight into their disruptive and influential nature.

Zeolite-based materials have demonstrated exceptional potential in the adsorption and removal of various environmental pollutants due to their tunable properties and high efficiency. This review highlights the significant advancements and comparative performance of various zeolite-based composites and their applications in pollution remediation. Zeolite composites such as Fe-Mn oxide/zeolite exhibit a capacity of 53.35 mg/g for Cu(II) adsorption, while Ni/zeolite achieves a capacity of 147.06 mg/g for the same pollutant. For Pb removal, an activated carbon-zeolite composite exhibits an outstanding capacity of 213.3 mg/g, showcasing the effectiveness of hybrid materials. In dye removal, zeolite X incorporated with karaya gum demonstrated an extraordinary capacity of 409 mg/g for Brilliant Green, underscoring its effectiveness in cationic dye sorption. Notably, chitosan/zeolite composites exhibit an adsorption capacity of 221 mg/g for indigo carmine, demonstrating excellent potential for dye removal. In CO2 capture, 4A zeolite modified with TEPA achieved a record capacity of 9.4 mmol/g at 25 °C and 5 bar, illustrating the effectiveness of amine-functionalized materials in greenhouse gas mitigation. Zeolite-based materials also show promise in hydrogen sulfide removal, with Na/Y zeolite achieving an impressive adsorption capacity of 204 mg H2S/g, surpassing industrial molecular sieves. These findings highlight the adaptability of zeolite-based adsorbents in addressing diverse environmental challenges. This review consolidates state-of-the-art advancements by integrating insights into adsorption mechanisms, isotherms, and material modifications. It provides a strategic framework for future research to optimize zeolite-based materials for specific pollutant removal applications.

In this study, soil samples collected from Burusa and Bure agricultural sectors were analyzed for their physicochemical parameters and potentially toxic elements (Fe, Mn, Zn, Cu, Co, B, Se, Ni, Cr, Pb, Cd, As, and Hg). Physicochemical parameters were analyzed according to AOAC methods. For quantification of PTEs, the soil samples were digested by using aquaregia (HCl: HNO3; 3:1) and 5 mL of H2O2 (30%) at a digestion temperature of 250 °C for 3 hours prior to ICP-OES analysis. The percent recoveries (%R) and relative standard deviation (%RSD) of this method ranged from 83 to 106% and 0.39 to 9.2%, respectively. The LODs and LOQ values were in the range of 4.3 × 10–4–5.3 × 10–2 mg/L and 1.4 × 10–3–1.76 × 10–1 mg/L, respectively. The analyzed mean values of physicochemical parameter including pH, temperature, electrical conductivity, moisture, organic matter and nitrogen content were found in the range of 4.85–6.47, 20.5–21.4 °C, 101.6–230.7 µS/cm, 8.67–20.7%, 0.677–1.81% and 5.81–6.85%, respectively. The average amount of potentially toxic elements found in the soil samples were ranged as 57073–81279, 1185–3255, 41.0–72.2, 12.6–29.2, 18.8–50.8, 25.0–40.5, 42.2–60.8, 13.6–34.5, 41.9- 67.2, 25.0–59.4, 9.92–13.3, 0.933–1.12 and 4.97–8.63 in mg/kg for Fe, Mn, Zn, Cu, Co, B, Se, Ni, Cr, Pb, Cd, As and Hg, respectively. The highest concentrations of among the entire PTEs were recorded for Fe, followed by Mn, in the analyzed soil samples. All the studied elements are below the FAO/WHO permissible limit except Fe, Se, Cd, and Hg for all analyzed soil samples and Mn for the Bure soil sample. The target hazard quotient (THQ) and hazard index (HI) values are <1, suggesting an insignificant non-carcinogenic risk of the heavy metals to the adults via ingestion, inhalation, and dermal contact exposure of agricultural soils. Likewise, the individual element incremental lifetime cancer risk (ILCR) occurrence for all studied soil samples is below 1 × 10–4. The total ILCR of potentially toxic heavy metals (Ni, Cr, Pb, Cd and As) resulting from ingestion, inhalation, and dermal contact exposure of agricultural soil by an adult population indicate a slightly higher potential cancer risk (> 1 × 10–4) for soil samples obtained from Bure S1, Bure S2, and Bure S3. Therefore, continuous monitoring of these harmful elements should be made by agricultural sectors and responsible government regulatory authorities are crucial to prevent PTEs related to agricultural soils in Ethiopia.

Metallic iron (Fe0) seems to be a well-acknowledged reactive material for water treatment at several scales. Many operating systems have been designed based on the premise that Fe0 is a reducing agent, transforming reducible species (E0 > –0.44 V) under environmental conditions (electrochemical reaction – electrons from Fe0). However, Fe0-remediation systems developed from this starting point are not optimally suited for harnessing their full potential. In contrast, the alternative approach regarding Fe0 as a generator of contaminant scavengers (e.g. iron oxides) and reductive species (e.g. FeII, H2) can allow for the tailored development of innovative systems capable of achieving various treatment objectives, including contaminant reduction through an indirect mechanism (e.g. electrons from FeII, Fe3O4, H2). This perspective article comparatively analyzes the two distinct approaches for the Fe0-based water remediation technology. Results show that the alternative pathway facilitates the design of Fe0-remediation systems to accommodate different Fe0-driven treatment processes, while potentially accomplishing enhanced treatment efficiency, at reduced costs. The resulting science-based systems have the potential to drive technological revolution in water treatment for achieving water security worldwide.

Marine environments, particularly coastal areas, are significantly impacted by human activities that introduce pollutants. Consequently, researchers are exploring ways to link contaminant exposure to adverse ecological effects, with biomonitoring using biomarkers proving especially effective.
This review examines publications from 2000 to 2023 on field passive biomonitoring of contamination in Latin American and Caribbean (LAC) coastal ecosystems, aiming to identify knowledge gaps and improve conservation strategies. Of the 277 articles analyzed, almost 60 % originated from Brazil, with Argentina contributing 15.52 %, Mexico 14.8 %, and other countries 10.10 %. Metals were the most frequently quantified contaminants (28.77 %), followed by hydrocarbons (13.4 %). However, most studies focused on a single contaminant, overlooking the fact that organisms are typically exposed to complex contaminant mixtures.
The most studied species were bivalves, gastropods, and teleost fishes, representing 24.62 %, 22.73 %, and 22.73 % of the total, respectively. Few studies examined aquatic plants and macroalgae, despite their known effectiveness as bioindicators.
A majority of the studies (56.21 %) concentrated on a single type of biomarker, with oxidative stress biomarkers being the most common (17.03 %). Although useful as "early warning" signals, these biomarkers lack specificity. Future research should prioritize identifying more specific biomarkers for different contaminants. Given the importance of biomonitoring in conservation management, increasing investment in marine sciences and securing stronger government commitment is crucial.

Coastal lagoons are marine environments with high economic importance due to their great role in seafood production. However, only a small fraction of coastal lagoons has been investigated for microplastic pollution, and considering hypersaline lagoons, the percentage drops even further. This study investigated microplastics (MPs) pollution for the first time in a Mediterranean hypersaline coastal lagoon. Our work reports an average abundance of 60 MPs/L with a statistically significant positive correlation to salinity. The microplastic particles identified in this study were primarily fragments of semi-synthetic fibers of cellulose acetate. A small amount was determined as polyester polyethylene terephthalate (PET), originating from fishing and touristic activities that occur in the area and potentially transported by the surface circulation of the NE Ionian Sea. Finally, this study shows that the mechanisms controlling the hypersaline conditions in the lagoon (atmospheric forcing and seawater intrusions) are also responsible for the higher concentration of MPs compared to other lagoons.

Pulsed light (PL) technology was investigated as a pesticide removal process. The degradation of 20 pesticides in water was monitored by mass spectrometry and revealed 74 photoproducts. Structure hypotheses were proposed for 47 photoproducts according to their fragmentation, isotopic pattern, and literature data. This work enabled the development of a LC-MS method for the relative quantification of photoproducts and for the absolute quantification of their parent pesticides.
This analytical method was then applied in optimizing the PL parameters. It was demonstrated that increasing voltage and fluence leads to more efficient pesticide degradation, with concentration reduction of 99 % for 14 pesticides. The compound sensitivity seems to be family dependent. Moreover, PL succeeded in degrading the photoproducts themselves.
Acute toxicity tests were performed on the bacteria Aliivibrio fischeri. A significant reduction in toxicity was observed for 10 out of 18 individual pesticides, while no increase was observed for the remaining seven. When applied to a cocktail solution, the toxicity decreased by 7.25-fold between the untreated and the most PL treated solution. This work demonstrates that PL is a promising process for removing pesticides from contaminated water. Further studies are needed to demonstrate the safety of treated wastewater on various trophic links.

Microplastics (MPs) and polyfluoroalkyl substances (PFASs) have emerged as emerging contaminants, drawing global attention due to their persistence and extensive presence in ecosystems. Although comprehensive studies exist on their individual behavior, their synergistic interactions remain unexplored, necessitating in-depth investigation to understand their impacts on environmental compartments. This review investigates the combined sources of MPs and PFASs, including commonly used daily products of human and wastewater treatment plant effluents, which release approximately 7.2 billion microplastics daily into aquatic environments and PFAS concentrations ranging from 8.1 to 24 µg/person/day. The review also discusses the mechanisms and environmental parameters that govern PFAS sorption over MPs. Studies indicate that the efficiency of PFAS retention increases with smaller, aged, or biofilm covered MPs due to larger surface areas, with adsorption rates varying from 20% to 85% depending on the type of MP and environmental conditions. Furthermore, the review explores the trophic transfer and combined toxicity of these contaminants, demonstrating that MPs act as carriers for PFAS, affecting their distribution, accumulation, and impact within ecosystems. These interactions can severely affect aquatic species, causing intestinal damage, oxidative stress, and disrupted reproductive systems in fish and other organisms. Despite these findings, significant knowledge gaps remain in understanding their interactions in complex ecosystems, particularly in terrestrial environments. Addressing these gaps requires developing standardized detection methods and conducting studies under realistic environmental conditions. Finally, this review suggests that future research should focus on developing combined removal strategies and source abatement measures to effectively manage the associated environmental and health risks.

Although comprehensive studies exist on their individual behavior, their synergistic interactions remain unexplored, necessitating in-depth investigation to understand their impacts on environmental compartments. This review investigates the combined sources of MPs and PFASs, including commonly used daily products of human and wastewater treatment plant effluents, which release approximately 7.2 billion microplastics daily into aquatic environments and PFAS concentrations ranging from 8.1 to 24 µg/person/day. The review also discusses the mechanisms and environmental parameters that govern PFAS sorption over MPs. Studies indicate that the efficiency of PFAS retention increases with smaller, aged, or biofilm covered MPs due to larger surface areas, with adsorption rates varying from 20% to 85% depending on the type of MP and environmental conditions. Furthermore, the review explores the trophic transfer and combined toxicity of these contaminants, demonstrating that MPs act as carriers for PFAS, affecting their distribution, accumulation, and impact within ecosystems. These interactions can severely affect aquatic species, causing intestinal damage, oxidative stress, and disrupted reproductive systems in fish and other organisms.

The widespread production of plastics has inflicted profound damage on our ecological systems, with microplastics (MPs)–minuscule particles resulting from plastic degradation—emerging as a critical pollutant that negatively impacts living organisms and ecosystems. Conventional methods of plastic disposal are inadequate in effectively mitigating these pollutants. In this context, photocatalytic technology has surfaced as a promising approach for the degradation of MPs. This review offers a comprehensive overview of the mechanisms underlying photocatalytic degradation, thereby enhancing the discourse that follows. Driven by light energy, MPs can undergo two distinct degradation pathways: (1) MPs are mineralized into carbon dioxide (CO2) and water (H2O) with the aid of photocatalysts, resulting in complete degradation; (2) MPs can be upgraded and recycled into hydrogen and other valuable compounds through redox reactions and photoreforming processes, offering a cost-effective approach to generating useful products. Additionally, we have refined the classification of photocatalysts, highlighting representative examples such as titanium dioxide (TiO2) and zinc oxide (ZnO) for in-depth discussion, and have systematically summarized the current research trends in this field. Lastly, we address the prevailing technological challenges in the photocatalytic degradation of MPs and propose potential solutions and future research directions, grounded in the current landscape of study.

Carbon dots (CDs) have emerged as a promising class of nanomaterials for addressing critical environmental challenges. Their unique optical, chemical, and electronic properties enable various applications, including microplastic detection, gas sensing, and water remediation. By leveraging their fluorescence properties, CDs can sensitively detect microplastics in diverse environmental matrices. Additionally, their ability to interact with gas molecules makes them suitable for developing efficient gas sensors to monitor air pollutants. In water remediation, CDs can be utilized as adsorbents, photocatalysts, and electrochemical sensors to remove heavy metals, organic pollutants, and other contaminants. Despite significant advancements, several challenges persist. These include the need for scalable and environmentally friendly synthesis methods, improved selectivity and sensitivity, and long-term stability. Future research should focus on addressing these limitations and exploring innovative applications of CDs in environmental remediation. By harnessing the potential of CDs, we can contribute to a cleaner and more sustainable future.
