Abstract Influenced by human activities, microplastics (MPs) are widely distributed in terrestrial ecosystems. However, their ecotoxicity remains unclear. Therefore, we assessed the of polyamide (PA-MPs) investigating toxic effects on model insect, silkworms Bombyx mori (Lepidoptera: Bombycidae). In this study, fifth-instar silkworm larvae were fed mulberry leaves treated with PA-MPs for 120 hours, but no changes mortality rates observed. body weight, pupal cocoon egg laying amount, and shell weight F 0 generation significantly reduced. This indicates that have sublethal silkworms. To further investigate offspring silkworms, applied age-stage, two-sex life table analysis. We found treatment group, duration larval stages 1 was prolonged, while lifespan adults total longevity shortened. Meanwhile, history parameters ( s xj , e l x f m v values) population R λ, r T ) group also lower than control. transgenerational effects, affecting growth, development, reproduction Our research findings demonstrate providing evidence ecotoxicity.

Application of Graphene-Based Solar Driven Interfacial Evaporation-Coupled Photocatalysis in Water Treatment

Catalysts, Journal Year: 2025, Volume and Issue: 15(4), P. 336 - 336

Published: March 31, 2025

The global shortage of freshwater resources and the energy crisis have propelled solar-driven interfacial evaporation (SDIE) coupled with photocatalytic technology to become a research focus in efficient low-carbon water treatment. Graphene-based materials demonstrate unique advantages SDIE–photocatalysis integrated systems, owing their broadband light absorption, ultrafast thermal carrier dynamics, tunable electronic structure, low enthalpy characteristics. This review systematically investigates enhancement mechanisms graphene photothermal conversion on processes, including (1) improving absorption through surface morphology modulation, defect engineering, plasmonic material compositing; (2) reducing via hydrophilic functional group modification porous structure design; (3) suppressing heat loss insulation layers 3D structural optimization; (4) enhancing transport efficiency fluid channel engineering wettability control. Furthermore, salt resistance strategies optimization significantly improve system practicality stability. In treatment applications, graphene-based SDIE systems achieve synergistic “adsorption–catalysis–evaporation” effects, enabling degradation organic pollutants, reduction in/fixation heavy metal ions, microbial inactivation. However, practical implementation still faces challenges steam condensation efficiency, insufficient long-term durability, high scaling-up costs. Future should prioritize mass transfer optimizing environmental adaptability, developing low-cost manufacturing processes promote widespread application systems.

Fate of microplastics in soil-water systems: View from free radicals driven by global climate change

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 295, P. 118138 - 118138

Published: April 1, 2025

Microplastics are ubiquitously distributed and persistently present in soil-water systems, posing potential ecological health risks worldwide. Free radicals highly reactive particularly at soil-water-air interface. The dynamic changes of free sensitive to environmental conditions may greatly impact the fate microplastics. However, pathways, reaction kinetics, or transformation products microplastic degradation by systems remains unclear. Climate change alters physical chemical environment this can directly affect microplastics, indirectly influence it altering generation species radicals. Here, we summarized analyzed fluctuations (such as superoxide radicals, hydrogen peroxide, peroxyl hydroxyl radicals) on microplastics their derivants. We also discussed how driven climate By integrating aspects such change, radical chemistry, pollution, work delineates critical issues pollution exacerbated condition changes. In response existing challenges deficiencies current research, feasible countermeasures proposed. This offers valuable insights for future research predicting controlling ecotoxicity caused associated with global change.

Aerobic and anaerobic microbial degradation in the wastewater treatment process affected by the presence of biodegradable packaging material made from plant by-products

Polymer Bulletin, Journal Year: 2025, Volume and Issue: unknown

Published: April 16, 2025

Abstract The paper explores how biodegradable packaging materials influence microbial respiration in activated sewage sludge. Experiments were conducted to measure biological oxygen demand (BOD) and anaerobic biodegradation, evaluating the biodegradability methane production potential of different bioplastic samples. These bioplastics often contain metal additives like silver, zinc, titanium, which are incorporated enhance antimicrobial properties, durability, functionality. presence these metals can degradation behavior materials, affecting both aerobic processes. Understanding role is crucial for environmental impact efficiency packaging. Findings reveal that containing silver nanoparticles those without biodegrade effectively. Despite variations, all samples consistently produced methane, indicating their suitability digestion findings suggest integration into waste management systems could provide a dual benefit reduction energy through capture, though further analysis needed understand practical potential. This work contributes novel insights metal-containing biodegradation processes real-world applications, advancing development more sustainable solutions.
