摘要

纳米技术为环境挑战提供了创新的解决方案,包括废水处理和工业废物管理。然而,城市污水、工业溶剂、农用化学品、重金属和纳米颗粒的广泛排放威胁着水生生态系统。虽然纳米材料有望用于污染修复,但它们的高表面反应性和小尺寸促进了生物转化,增加了它们与环境的相互作用,破坏了水生食物网,特别是在热带和亚热带地区。本文综述了工程纳米颗粒(ENPs)对水生生物的不利影响,重点介绍了它们在物种中的生物积累。二氧化钛纳米粒子的生物累积率高达86%,而铜纳米粒子的累积率仅为0.9 ppb。受影响的器官包括鳃、脑和肺,这突出了纳米颗粒污染的广泛影响。生物膜增强纳米颗粒吸附和污染物运输。本研究引入生物积累指数(BAI),改进了生物积累评价方法。研究结果强调需要监管框架、可持续纳米技术和先进的监测来减少环境风险。未来的工作应侧重于长期毒性研究、生态友好型设计和缓解策略。整合生物积累模型和风险评估工具可以帮助平衡技术进步和水生生态系统的可持续性,促进负责任的纳米技术,创造一个更清洁的未来。图形抽象

Ecotoxicological evaluation of nanosized particles with emerging contaminants and their impact assessment in the aquatic environment: a review

Nanotechnology offers innovative solutions to environmental challenges, including wastewater treatment and industrial waste management. However, the widespread discharge of municipal sewage, industrial solvents, agrochemicals, heavy metals, and nanoparticles threatens aquatic ecosystems. While nanomaterials hold promise for pollution remediation, their high surface reactivity and small size facilitate biotransformation, increasing their environmental interactions and disrupting aquatic food webs, particularly in tropical and subtropical regions. This review examines the adverse effects of engineered nanoparticles (ENPs) on aquatic life, emphasizing their bioaccumulation in species. Titanium dioxide nanoparticles exhibit bioaccumulation rates of up to 86%, whereas copper nanoparticles accumulate at only 0.9 ppb. Affected organs include the gills, brain, and lungs, highlighting nanoparticle contamination’s widespread impact. Biofilms enhance nanoparticle adsorption and pollutant transport. This study introduces the bioaccumulation index (BAI), improving bioaccumulation assessment over conventional methods. Findings stress the need for regulatory frameworks, sustainable nanotechnology, and advanced monitoring to reduce environmental risks. Future work should focus on long-term toxicity studies, eco-friendly designs, and mitigation strategies. Integrating bioaccumulation models and risk assessment tools can help balance technological progress with aquatic ecosystem sustainability, promoting responsible nanotechnology for a cleaner future.

期刊介绍: The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
