TLDR
It is suggested that Ag MNP coating does not need to be taken into account to understand fate of AgMNPs applied to soil through biosolids amendment, because pre-incubation with sewage sludge negated these effects.About:

Comparative biokinetics of pristine and sulfidized Ag nanoparticles in two arthropod species exposed to different field soils
Iva Talaber,Cornelis A.M. van Gestel,Anita Jemec Kokalj,Gregor Marolt,Sara Novak,Primož Zidar,Damjana Drobne +6 more
TL;DR: In this article, the authors analyzed the biokinetics of pristine and sulfidized Ag NPs in two arthropod species with different routes of exposure to soil contaminants (isopod Porcellio scaber and springtail Folsomia candida) exposed to 4 different soils, widely differing in chemical and physical properties.

Impact of anaerobically digested silver and copper oxide nanoparticles in biosolids on soil characteristics and bacterial community.
TL;DR: The population of the highly abundant bacteria that have important physiological roles in soil decreased, while the less important bacteria for soil function were able to thrive, indicating the need for long-term field studies.

Transport and fate of silver as polymer-stabilised nanoparticles and ions in a pilot wastewater treatment plant, followed by sludge digestion and disposal of sludge/soil mixtures: A case study
TL;DR: The findings show that risk assessments and toxicological studies of Ag NPs suspensions must take into account possible chemical and particle transformations upon environmental entry, as silver in general become less soluble when transported to WWTPs and interacting with sludge, and soil.

The fate of cerium oxide nanoparticles in sediments and their routes of uptake in a freshwater worm.
TL;DR: Assessment of the contribution of dietary and transdermal uptake in the bioaccumulation of cerium oxide nanoparticles (CeO2 NP and soluble Ce(III)NO3) using the freshwater worm Lumbriculus variegatus as a model species concluded that these particles may translocate across the gut wall.

Fate and Transport of Silver Nanoparticles in the Environment
TL;DR: In this paper, the authors introduce recent model and experimental studies on the transport and distribution of AgNPs in air, aquatic, and terrestrial systems, and discuss the transformation of AgNs in the environment including change of coating, aggregation, sedimentation, dissolution and re-reduction, sulfidation and chlorination.

A study of the nucleation and growth processes in the synthesis of colloidal gold
TL;DR: In this paper, a preliminary survey with the electron microscope of various preparations of colloidal gold, a study was made of the process of nucleation and growth in gold colloids, and it was shown that nucleating agents may be identified with reducing agents which form a mixed polymer with chlorauric ion before the reduction to the nucleus takes place.

Analysis of Macromolecular Polydispersity in Intensity Correlation Spectroscopy: The Method of Cumulants
TL;DR: The first order electric field correlation function of laser light scattered by polydisperse solutions of macromolecules can be written as a sum or distribution of exponentials, with decay rates proportional to the diffusion coefficients of the solute molecules as discussed by the authors.

Modeled Environmental Concentrations of Engineered Nanomaterials (TiO2, ZnO, Ag, CNT, Fullerenes) for Different Regions
TL;DR: The results of this study indicate that risks to aquatic organisms may currently emanate from nano- Ag, nano-TiO(2), and nano-ZnO in sewage treatment effluents for all considered regions and for nano-Ag in surface waters.

Nanoparticle Silver Released into Water from Commercially Available Sock Fabrics
Troy M. Benn,Paul Westerhoff +1 more
TL;DR: Variable leaching rates among sock types suggests that the sock manufacturing process may control the release of silver, and physical separation and ion selective electrode (ISE) analyses suggest that both colloidal and ionic silver leach from the socks.
