Special Issue Information

Dear Colleagues,

Nanoplastics are widely distributed in all environmental systems, including air, water, soil, and living organisms. Nanoplastics are heterogeneous nanomaterials that consist of polymers and additives such as plasticizers, fillers, and pigments. They are generated or derived from the degradation of everyday plastic consumer products. In addition to their complex composition, nanoplastics can adsorb toxic pollutants from the surrounding environment, such as metals and organic contaminants. Because of their complex composition, interaction with environmental contaminants, small size, and large surface area, nanoplastics could later the fate and transport of other contaminants, release metallic and organic contaminants, and, therefore, pose risks to environmental and human health.

This Special Issue is dedicated to original research and critical review articles. Topics of interest include state-of-the-art nanoplastic sources, emission, distribution, and monitoring in different environmental compartments; fate, transport including in porous media, water treatment, acute and chronic effects of nanoplastics; and the biophysical–chemical mechanisms of their potential toxicity. This Special Issue is open to original contributions on mechanisms, modeling, solutions limiting teratogenic effects, genomic and proteomic approaches, remediation solutions, recommendations, standards and intelligence artificial (IA) based methods.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Information about the influence of surface charges on nanoplastics (NPLs) transport in porous media, the influence of NPL concentrations on porous media retention capacities, and changes in porous media adsorption capacities in the presence of natural water components are still scarce. In this study, laboratory column experiments are conducted to investigate the transport behavior of positively charged amidine polystyrene (PS) latex NPLs and negatively charged sulfate PS latex NPLs in quartz sand columns saturated with ultrapure water and Geneva Lake water, respectively. Results obtained for ultrapure water show that amidine PS latex NPLs have more affinity for negatively charged sand surfaces than sulfate PS latex NPLs because of the presence of attractive electrical forces. As for the Geneva Lake water, under natural conditions, both NPL types and sand are negatively charged. Therefore, the presence of repulsion forces reduces NPL’s affinity for sand surfaces. The calculated adsorption capacities of sand grains for the removal of both types of NPLs from both types of water are oscillating around 0.008 and 0.004 mg g−1 for NPL concentrations of 100 and 500 mg L−1, respectively. SEM micrography shows individual NPLs or aggregates attached to the sand and confirms the limited role of the adsorption process in NPL retention. The important NPL retention, especially in the case of negatively charged NPLs, in Geneva Lake water-saturated columns is related to heteroaggregate formation and their further straining inside narrow pores. The presence of DOM and metal cations is then crucial to trigger the aggregation process and NPL retention. Full article
