摘要

磁性氧化铁纳米粒子(FexOy NPs,主要是 Fe3O4 和 γ-Fe2O3)是一种普遍存在于水生、陆地和大气环境中的纳米材料,具有高普遍性和复杂的来源。过去十年间,随着分离和检测方法的快速发展,关于人体内存在外源粒子的报道层出不穷。由于磁性非氧化物 NP 存在于人体血液和脑组织中,特别是可能与阿尔茨海默病等神经退行性疾病相关,因此其对健康的危害日益受到关注。本文全面概述了磁性 FexOy NP 的来源、分析方法、环境影响和健康风险。目前,大多数研究主要基于工程化的 FexOy NP,而关于实际环境中存在的磁性 FexOy NP 的报道仍然有限,特别是关于它们在各种环境基质中的出现水平、环境转化行为和生物毒性效应的报道。我们的研究回顾了这种新兴污染物,为解决当前研究的不足提供了见解,并为未来的研究指明了方向。

Magnetic iron oxide nanoparticles: An emerging threat for the environment and human health

Magnetic iron oxide nanoparticles: An emerging threat for the environment and human health

Magnetic iron oxide nanoparticles (FexOy NPs, mainly Fe3O4 and γ-Fe2O3) are nanomaterials ubiquitously present in aquatic, terrestrial, and atmospheric environments, with a high prevalence and complex sources. Over the past decade, numerous reports have emerged on the presence of exogenous particles in human body, facilitated by the rapid development of separation and detection methods. The health risk associated with magnetic FexOy NP have garnered escalating attention due to their presence in human blood and brain tissues, especially for their potential association with neurodegenerative diseases like Alzheimer's disease. In this paper, we provide a comprehensive overview of sources, analysis methods, environmental impacts, and health risks of magnetic FexOy NP. Currently, most researches are primarily based on engineered FexOy NP, while reports about magnetic FexOy NP existing in real-world environments are still limited, especially for their occurrence levels in various environmental matrices, environmental transformation behavior, and biotoxic effects. Our study reviews this emerging pollutant, providing insights to address current research deficiencies and chart the course for future studies.

期刊介绍: The Journal of Environmental Sciences is an international journal started in 1989. The journal is devoted to publish original, peer-reviewed research papers on main aspects of environmental sciences, such as environmental chemistry, environmental biology, ecology, geosciences and environmental physics. Appropriate subjects include basic and applied research on atmospheric, terrestrial and aquatic environments, pollution control and abatement technology, conservation of natural resources, environmental health and toxicology. Announcements of international environmental science meetings and other recent information are also included.
