Special Issue Information

Dear Colleagues,

With the rapid development of nanotechnology, functional nanomaterials offer numerous unique properties and functionalities that enable them to effectively remove and mitigate various types of pollutants. These materials can be tailored to target specific new pollutants, such as persistent organic pollutants (especially perfluorinated compounds), endocrine disrupters, antibiotics, and even microplastics. Their small size and high reactivity also make them suitable for real-time monitoring and the analysis of pollutants in the environment.

However, the ecological risk assessment of nanomaterials is of utmost importance. Despite their potential benefits, these materials may also introduce unintended ecological risks due to their unique physicochemical properties. Potential risks include the toxic effects of nanomaterials on aquatic organisms and terrestrial organisms, bioaccumulation in food webs, and the potential transport of nanomaterials through different environmental compartments.

This Special Issue seeks submissions that address the control of new pollutants released by functional nanomaterials and the ecological risk assessment of the latter. In this Special Issue, original research articles and reviews are welcome.

In recent years, microplastics (MPs) have emerged as a significant environmental pollutant, garnering substantial attention for their migration and transformation behaviors in natural environments. MPs frequently infiltrate natural porous media such as soil, sediment, and rock through various pathways, posing potential threats to ecological systems and human health. Consequently, the migration and adsorption mechanisms applied to MPs in porous media have been extensively studied. This paper aims to elucidate the migration mechanisms of MPs in porous media and their influencing factors through a systematic review. The review encompasses the characteristics of MPs, the physical properties of porous media, and hydrodynamic factors. Additionally, the paper further clarifies the adsorption mechanisms of MPs in porous media to provide theoretical support for understanding their environmental behavior and fate. Furthermore, the current mainstream detection techniques for MPs are reviewed, with an analysis of the advantages, disadvantages, and applications of each technique. Finally, the paper identifies the limitations and shortcomings of current research and envisions future research directions. Full article
